Show HN: Write a private diary using good old email

    Yesterday Paul Graham asked for an email diary service (

    > Is there an easy way to build, or a startup that offers, something that will email you once a day asking "What's happening?" and then accumulate the replies?

    I did just that! Let me know what you think.

      He also wrote

      > Unfortunately, though, in this one case I can't promise that if you build it, I'll use it. Unless I know you, I can't trust that you won't read my emails. (I trusted the previous startup that did it because we'd funded them.)

      How do you solve the "won't read my emails" problem ?

      I've seen the statement in your website:

      > Your data stored and transferred securely. No one will ever read or process your notes even the staff. Your data belongs to you and can be easily exported in preferable format by request.

      But once the data leaves the browser there is no way to know, wouldn't you consider to partner with Gmail(or others) and appear as an addon to an already trusted company in order to start off the business ?

        99% of the people who tell you they wouldn’t use the product unless it can’t read your email wouldn’t actually use it regardless, and are just asking for things they don’t really have any intention of using.

        edit: I just wanted to add I think it's kind of a dick move on pg's part to ask someone to build this when there are like four different versions that already exist. If you like those products then you should promote them, and if you don't like them then you should email the creators with feedback. Asking folks to build additional competing products without doing that first is poor form, as is asking people to build stuff that you don't actually care enough about to Google to see if it already exists. I don't mean to pick on pg specifically, I just see this kind of behavior on Twitter (and HN) all the time, often from startup investors, and I think it deserves to be called out.

          Working for a manufacturing company this is of my biggest pet peeves. Our Salesforce (and customers) insist that they _would/could_ sell (or buy) our product if only it had feature x. In my experience, most of those people aren’t really interested to sell (or buy) the product regardless of feature set.

          • keanzu 10 days ago

            Contingent Purchase Order : You put in a purchase order and we'll build feature x.

            Separate the wheat from the chaff.

            • jakobegger 9 days ago

              I think this is how a lot of enterprise software is sold. Potential customer says "it's missing x", sales person says "we'll build x in two weeks", product is sold, devs have to figure out how to build x in two weeks.

              That probably doesn't work for physical products.

              • Wowfunhappy 10 days ago

                Are you going to build it instantly?

                If not, what happens if someone else releases a superior product in the interim? Or my business needs change?

                • keanzu 10 days ago

                  Both excellent questions. Oddly the tire kicker never says "If you build X then I'll buy it .. unless my needs change or someone else releases a superior product". Requesting a purchase order casts the situation in the cold light of day.

                    They'll get your business.

                    > Or my business needs change?

                    I didn't waste my time building you a feature you won't pay for.

              • rattray 10 days ago

                How do you know pg didn't do that already?

                • joshdance 10 days ago

                  what are the four versions that already exist?

                > How do you solve the "won't read my emails" problem?

                Have the user generate a device-local SMIME certificate for <>, register their certificate's public key with the server, have the server generate a mobileconfig that enforces SMIME when emailing anyone, and then in change the From: address to <> when emailing the diary address. iOS will remember that From change and use SMIME to encrypt all diary messages to the public key in your keychain (which the server can't decrypt), the server can reroute the incoming mail back to you using your private key, and your device-local key is the only one capable of decrypting.

                Since you're using SMIME, you'll need to use IMAP for your data store, which provides perfect compatibility to any platform that can do SMIME key generation. I'm very curious if SMIME-encrypted emails can be used as encrypted Notes on iOS, now that Notes supports IMAP accounts :)

                • baby 10 days ago

                  Hey! S/MIME is broken (see eFAIL) and I don’t believe there exist any mitigation’s to the attacks that have been published.

                  tl;dr: there exist ways to read your emails without knowing the private keys.

                  • floatingatoll 9 days ago

                    eFAIL documents a series of client implementation errors in a 2018 paper that allow attackers to exfiltrate plaintext by emailing you your own encrypted messages with an attacker payload.

                    Diary site implementations will need to carefully evaluate whether this is relevant to them or to their users, who may well have been fine emailing plaintext to begin with (if you want an encrypted diary, you probably aren’t going to use email to write in it), before they assume that it’s a concern and begin testing email clients.

                    • baby 9 days ago

                      IIRC this is true for PGP but not for S/MIME which was broken at the protocol level.

                    • busngklaznm 10 days ago

                      Do you know what eFAIL is?

                      tl;dr; there needs to be javascript in the mail and that must abuse the MUA. If you don't send JS exploit for your own MUA, you are in no danger...

                      Also, I understand the concern and that Paul most likely will not trust their secrets to anyone. The problem is that's not a business, but a beautiful hobby project that I honestly love, so it's unlikely that I will ever spend time rewriting it and then paying Google $15K ( so they could vet me.

                      • newzombie 10 days ago

                        An idea would be to open source it and make it simple to run an instance.

                          I respect if it's not what you're looking for but you may be able leverage yourself into a good position (with the community and with PG) as a result of the publicity + traction combo.

                          Great work getting that ball rolling so quickly!

                          > I addressed it in a comment:

                          As I read that, users must trust you. There's nothing that would actually prevent you from accessing the data.

                          So it's arguably misleading to call it a "private diary".

                          • ViViDboarder 10 days ago

                            I disagree. I believe that it’s more common for “private” to mean “between you and the company”. Eg. Private accounts on other services, or private information associated with your account.

                            • mirimir 10 days ago

                              You certainly have a point about "private". As you say, with a service provider. Or with family, friends and associates.

                              But none of that is relevant for "private diary". There, it's privacy between you and your diary.

                              • ViViDboarder 8 days ago

                                Plenty of people had “private” LiveJournal accounts back in the day with no expectation that it was a zero-knowledge system. Just that they weren’t sharing it. I may not be a good indication of “most people”, but I just don’t think that most people think of privacy in the way that we (folks who know details of encryption and metadata leaks) do.

                                • mirimir 7 days ago

                                  Fair enough.

                                  But that's the problem, isn't it? I mean, many people do (sort of magically) think that their online stuff is private. And then they get pwned in one way or another.

                          • j45 10 days ago

                            This service could run just fine on one or two VPS’ on DigialOcean, etc. Zero knowledge encryption could help secure the content too, it there is ultimately trust needed.

                                    unlike "Diary Email" your readme makes it very clear where the emails go, and since I'd host it I know no-one would read it.

                                        Not if the server admins of both sides are even remotely competent. A good "email server" will at least allow, if not enforce encryption client<->server and (if supported by the other party) server<->recipients_server.

                                    Remember KISS. He wants a Gmail add-on? Keep it even simpler.

                                    Create a filter that applies a "Journal" label to emails from your own address. Then create a filter to have it skip your inbox. Whenever you want to view your journal, just search for archived mail with that label.

                                        Isn't the point of a diary that nobody can read it but you? That's why they have locks on them.

                                        If you want a diary that other people can read, that's called a blog.

                                              To paraphrase jwz: "Some people, when confronted with a problem, think 'I know, I'll use PGP.' Now they have two problems."

                                              More seriously, PGP is really hard. I think it has some potential for signing emails from your bank, Amazon, etc. but other than that ... it's just a pain. I'm not a crypto expert but a reasonably skilled IT professional, and even I struggle with it.

                                                Yes, the message is encrypted with a key, you only get access to this key by decrypting it with your private key. Everyone on the email has the key for the message encrypted with their public key. Hence the privacy is not perfect but pretty good.

                                                  Encrypt it with a symmetric key, and then encrypt the symmetric key separately with each of your friends' public keys.

                                                    Nobody but a handful of very vocal HN posters care about this. In the marketplace this isn’t a problem.

                                                    At the end of the day, you have to trust your data in somebody else’s hands. Unless your print your own circuit boards, make your own CPUs and write your own operating system, you cannot escape trusting a third party.

                                                    • Carpetsmoker 10 days ago

                                                      It's not a completely unreasonable concern though; all of the big tech companies have had problems with employees misusing their access to private communications to snoop on people.

                                                      When my mother worked at the local government she (illegally, and unethically) accessed the file of a friend, and learned that a friend lied about the reason she's in a wheelchair, the real reason being somewhat embarrassing. She told all mutual friends about it too and caused big drama (she's a toxic person). This was over 20 years ago btw, privacy problems aren't new (just the scale of it has changed).

                                                      In the Netherlands we have a municipal database with data for all citizens. Civil servants legitimately access it in the course of their duties, but names for famous Dutch people have many more hits than regular ones. I think especially for high-profile(ish) people like Paul, it might be more of a concern than you or me.

                                                      I'm not paranoid about it, but I do think there's room for improvement.

                                                      Since when is Google a "trusted company" when it comes to user-generated content? Their business model is literally to gather as much data as possible from their users in order to manipulate their collective behavior to Google's financial benefit.

                                                        There’s several ways to encrypt he content for the owner, including zero knowledge. Complications and risks as a result.

                                                          true end-to-end encryption is the only way?

                                                            Just encrypt locally before sending.

                                                                    Does this mean these companies are outsourcing their graphics, mock ups, etc.?

                                                                      • ska 10 days ago

If you just start adding corporate logos to your site you'll end up talking to lawyers eventually - at least if you have any sort of traction.

                                                                        On the other hand "Used by X" can mean anything from "X uses us as a core part of their workflows" and "A small team at X uses this sometimes". So don't give it much weight.

                                                                          For example, even though Salesforce obviously has a lot of talented programmers on the payroll, I wouldn't be at all surprised if the Dreamforce conference website is built by a separate firm.

                                                                          • the_watcher 10 days ago

This is a killer feature that I have never seen in my 18 years as a PM. PM tools still pose high barriers for adoption, in general, since you have to login, navigate, find elements you are related to, analyze them and then feedback. That's a long path if you are not fully allocated into the project. I think there is a lot of room for "feedback automation" via email in Pm tools.

                                                                                            the plus syntax is part of the email address specification. any server that doesn't support it is by definition buggy because some mail won't work as expected or designed.

                                                                                            • Carpetsmoker 9 days ago

                                                                                              Many mail servers have a setting to configure which character to use; some default (or used to default?) to "-" instead of "+".

                                                                                              • lolc 10 days ago

The plus sign is an allowed character in the local part in the spec. But mailservers are not required to treat it specially and apparently Exchange doesn't. That seems to be the thrust of the comment you answered to.

                                                                                                • newscracker 9 days ago

They just use a regex that looks for alphabets, numbers, underscores, dots and one @ sign (I've also seen forms that won't accept any TLD other than .com).

                                                                                                  • pests 10 days ago

                                                                                                  • capableweb 10 days ago

                                                                                                    Edit: doesn't mean everyone will use it though! But guess the plus sign in addresses would be more "email" than just email.

                                                                                                    • Spivak 10 days ago

                                                                                                      It’s nice that they’re trying to standardize it but it’s an impossible standard since you can’t assume that any particular domain adheres to to it so you end up with a whitelist either way.

                                                                                                      • capableweb 10 days ago

                                                                                                        I guess you're seeing it from the service owners point of view, and in that case it doesn't really matter no? AFAIK, it's for the owners of the email to use the subaddressing, not for others to magically come up and use subaddressing.

                                                                                                        So as long as you, the user and owner of an address, know that your domain supports/not supports it, you can use it.

                                                                                                        I don't understand who would have to add any allow/blocklists?

                                                                                                      I know someone who constantly complained that web site X or company Y are stupid, because they don't follow the RFCs, don't know the syntax of mail addresses, because mail validation in web forms often rejected anything with a plus sign.

                                                                                                      The correct answer would have been "don't do it then" or maybe "how about configuring your Exim so that instead of '+' you're using '-' as a separator, but I suppose the complaining was a big part of the fun.

                                                                                                      • polynomial 10 days ago

                                                                                                        It's super powerful, but uses few resources compared to vscode/intellij. Not to mention it can handle massive text files like a champ.

It's kinda clunkly for one-off files and text editing though, which is why I prefer sublime for a lot of that stuff.

                                                                                                                  your readme still mentions needing a mongo for scheduling if not on heroku. not sure if that's something that didn't get changed or still true.

                                                                                                                  Also, for those of us who never used OhLife the readme doesn't really tell me what it does.

                                                                                                                  • vonnieda 10 days ago

When it shut down I started using DailyDiary [0] which launched an Oh Life importer on Oct 8th, 2014. That's _before_ Oh Life even shut down on Oct 15th, 2014.

                                                                                                                  I've been continuing to use DailyDiary since.

                                                                                                                  I have an apps script that automatically adds a draft response to these prompts, which still starts with an "Oh Life, ...." salutation. The script also adds the day's weather report to the bottom of the draft. My todo list has an item to add top and random tracks from my scrobbled music listening for the day.

                                                                                                                  In the evening I fill in the body of the response with reflections from the day and off it goes.

                                                                                                                        • j45 10 days ago

                                                                                                                          Email only authentication would presumably outlive any provider.

                                                                                                                          I bought into the MyOpenID SSO excitement once, it worked pretty well until it went away. After that, back to email accounts, identity providers like Google/MS/Twitter don't end to know everytime you're logging into your app.

                                                                                                                                  I'll cite one aspect of its design and implementation as a problem – it doesn't support standard protocols like IMAP unless you choose a paid plan. Even then, you have to use a "bridge application". On mobile, only the official app can access the mailbox. To sum it up, if you're on a free plan on ProtonMail, you cannot export your mails out (unless you do it by "printing" mails one by one). To contrast this, even "free" platforms like Gmail and Yahoo provide IMAP access to all accounts.

                                                                                                                                  • Summershard 9 days ago

All your data is invisible to them. If you could use IMAP without a bridge app, which encrypts and decrypts all your mail data locally, guys at Proton could read your mails. Not necessarily because they would want to. That's just how email works.

                                                                                                                                • groovybits 10 days ago

                                                                                                                                  • ocdtrekkie 10 days ago

Honestly, you should use a mail server that isn't from an ad company. And then if you also want to layer encryption on top, feel free.

                                                                                                                                    (Also, calling PGP "the best encryption there is" might be a bit of hyperbole.)

                                                                                                                                    • bad_user 10 days ago

                                                                                                                                      And the company's business model is absolutely irrelevant actually. You still need end to end encryption.

                                                                                                                                      > "But then will your diary service work right with it?"

                                                                                                                                    I know it's largely a one person experiment and not a real business, but some feedback

                                                                                                                                    > I won't sell your data and will be very personal with you.

                                                                                                                                    This isn't good enough anymore. You need to promise that my data won't ever _ever_ be sold. Especially since you're asking me to share my diary with you. I'm not sure if this kind of promise can be made though. Maybe we need some legal apparatus you can declare that gives me peace of mind that no future owner of your company can change their mind.

                                                                                                                                    • oefrha 10 days ago

Honestly not sure why anyone would entrust their diary to some web service, unless they take a nothing-to-hide approach with their diaries.

                                                                                                                                      Although, a web service to share notes with friends is probably okay.

                                                                                                                                      • Waterluvian 10 days ago

But it can mean a lot of things. I can imagine cases where people are okay with that. I've managed a personal "diary" that's on Github publically. It's really just a reference of tech stuff I've learned.

I don't have a fancy lawyer that could customize such thing to me, nor I have a budget for it.

                                                                                                                                        Here're some facts that could help you to find peace of mind. First of all, I operate in the EU, so I can't simply sell your data. Also, it costs me virtually $0 to maintain the service (thanks to Firebase and Mailgun), so I won't be forced to sell out to keep it afloat. At last but not least I use it myself with my close friends so we're in the same boat.

                                                                                                                                        • basch 10 days ago

But further I love when some well off VC (Fred Wilson does this type of thing often) will ask the community for something they could simply pay someone to write that fills 100% the need they have and is tailored toward them specifically with features that they want. Or just hack it together themselves. Much easier generally (for this type of thing) than having to trust and use a product with bells and whistles that may not matter to you.

                                                                                                                                              • athenot 10 days ago

                                                                                                                                                The very humble Notes app on macOS/iOS fulfills this for me. I just start typing, the minimalistic interface gets out of the way. Timestamping is on last modification instead of creation date but I add one manually. That's about my only drawback. Some features I find compelling:

                                                                                                                                                - I can start a train of thought on the mac, continue it on the phone and complete it on my mac.

                                                                                                                                                - It's not mined by some advertising company, no subject to the viability of some business.

                                                                                                                                                - Being so simple, the contents can be exported to some other format very easily.

                                                                                                                                                - Works offline (only background sync requires connection).

                                                                                                                                                - And search is near instant since everything is stored locally.

                                                                                                                                                • graeme 10 days ago

                                                                                                                                                  My first thought when reading this was “how do you automate it?” as that was part of the spec.

                                                                                                                                                  But you can actually do that with Shortcuts, which is build into the system.

                                                                                                                                                  1. Make a note with a title like “journal” or “daily log”

                                                                                                                                                  2. Open shortcuts, go to automations. Make a new one with a time of day trigger. (Or an alternate if you prefer)

                                                                                                                                                  3. Actions: “find all notes where” —> filter for notes name. “ask for input” —-> ask the question you want + put “current date” as default entry. “Append to note” —> use magic variables. Select ask for input as the text to append, and note as the note to append to. (Specifically, the note your filter found)

                                                                                                                                                  4. Duplicate this for as many times of day as you want to be asked

                                                                                                                                                  5. At the appropriate time, click the notification and enter text to log it. Also add a trailing newline for note formatting. If anyone knows how to automate this on shortcuts, let me know: newlines seem tricky and I haven’t figured it out.

                                                                                                                                                  This automates the asking, and also the timestamp. Thanks for posting your idea, it prompted me to setup alerts for 11:00 and 5:00 pm.

                                                                                                                                                  Edit: this doesn’t transfer bullets to notes. If anyone knows how to append bulleted text via shortcut, let me know.

                                                                                                                                                  • dpeck 10 days ago

                                                                                                                                                    Thats a nice little hack. Shortcuts is really powerful for little workflows like this.

                                                                                                                                                    I've done similar for reminders of things that I want to take measurement of in a simple way throughout a day. Like taking a childs temperature when they're sick and running a fever.

                                                                                                                                                    • graeme 10 days ago

                                                                                                                                                    • ryanjm33 10 days ago

                                                                                                                                                      I have gotten really into using it on my Mac (writing) and my iPhone (reading/updating) but unfortunately it is insanely buggy on iPad when using a keyboard, or at least when using the Magic Keyboard.

                                                                                                                                                      Buggy enough that I have to use something else for taking notes with iPad+Keyboard. I've found Bear[0] to be pretty good but not better for my use-case than a less-buggy Notes would be.

                                                                                                                                                      Since "ubiquity" and "simplicity" are the two main selling points for standard Notes, this is proving to be pretty annoying: I sometimes write in Bear then copy-paste back into Notes.

                                                                                                                                                        Otherwise, I'm also a fan of how perfectly minimal and focused Notes is for journaling.

Might give it another try, thanks for reminding me.

That has been a sticking point for me, only having the export of individual notes to PDF as a built-in option.

                                                                                                                                                            • nickloewen 10 days ago

                                                                                                                                                              If you copy-paste from the notes app, it tends to do a reasonable job transforming it’s formatting into a plain-text representation.(Or rich-text, if you paste into an app that supports it, like Pages or Mail.)

                                                                                                                                                              There are a few apps around that can do this in bulk. I have one called Notes Exporter. Apparently Note2Txt is also good:

                                                                                                                                                              I am a little worried that some day these tools will disappear, but iirc the notes are just kept in an sqlite database so it shouldn’t be too hard to hack your data out manually, either.

                                                                                                                                                            • j45 10 days ago

                                                                                                                                                              It prompts you in email not having to change applications. This is good for people who like inbox zero and are in their emails all day anyways.

                                                                                                                                                                  Also you probably don't need a service, personally I can just send email to yourself, PGP encrypted. The only bit that's missing is a periodic reminder, to which you can reply. But I can probably set that up as a cron job.

                                                                                                                                                                        Many of us were not aware of privacy issues then, plus we were naive enough to think that the services we adopted would survive if cool enough.

                                                                                                                                                                        I loved OhLife, but now 10 years later I wouldn't subscribe to a clone. Fool me once etc.

(though probably will be hard to extend to people who don't know/like terminal editors, or command line itself)

It's primarily web-based, but you can make it email-based if you wish to. Basically, you'd set up a daily reminder at a specific time, and you can reply directly to that email to make a new entry.

                                                                                                                                                                            I should point out that Penzu is not a completely free service. There is a basic free tier, and then there are paid plans with additional features.

                                                                                                                                                                              Why not just write the e-mail in your current e-mail client and then store the draft in its own folder?

                                                                                                                                                                              People have been doing that for centuries. They'd write a letter to themselves and then store it in a box somewhere instead of sending it.

                                                                                                                                                                              Some people took it a step farther and would write the letter, and then burn it if they were angry. Very cathartic.

                                                                                                                                                                              • taneq 10 days ago

                                                                                                                                                                                This was my first response, too. Just email yourself with subject "diary", then the next day, reply to that email, etc. You can even have multi-user versions by sending it to someone(s) else and everyone just replies all. If you self-host your email then it's fairly secure, and has all of the advantages but none of the disadvantages.

                                                                                                                                                                              • josephwegner 10 days ago

                                                                                                                                                                                This is a real "Dropbox is just rsync" sort of comment, but I personally use a small CLI util for this[1]. It automatically creates a new text file for each day that I use it and stores it in a dated folder/file. I can look at notes by day, or grep around in that directory fairly easily. And it syncs to wherever, so I can also just search within my file storage service.

                                                                                                                                                                                I use this for both regular "diary" sort of journaling as well as notes around what I was doing on a particular day. It's wildly useful keeping daily notes on things, for questions like "Hey, do you remember that bug we dealt with last year...?"

                                                                                                                                                                                      Congratulations, from a fellow hacker - what's it been, 2 days? That's really impressive speed, especially considering it's nice looking.

                                                                                                                                                                                      A lot of people would confidently assume they could knock this out in a couple of days no problem, but it'd actually take them a few weeks at minimum. I had a post on the front page a few weeks ago on the topic [0], perhaps you saw it - I could learn a lot from you :-)

I mean, imagine browsing twitter and noticing that Paul Graham asks for someone to build the very product you're sitting on fully formed :-)

                                                                                                                                                                                        It has a single notification per day which is directly actionable (Asks for your mood for the day).

                                                                                                                                                                                        Data is stored locally on the phone and can be backed up to your iCloud/Google Drive.

                                                                                                                                                                                        I have found this app to be more habit forming in terms of creating a micro-diary, rather than sitting down and jotting thoughts.

                                                                                                                                                                                        • haberdasher 10 days ago

By default emails would become new posts. SMS would append to the latest entry, or I could create a new one with a keyword (NEWPOST title, I think).

                                                                                                                                                                                            This was a nice way to create and update travel journals before mobile internet and smartphones were widespread.

                                                                                                                                                                                            • crtlaltdel 10 days ago

It's even encrypted.

I used to run my own private wordpress, and it was nothing but headaches, and fear of dataloss.

                                                                                                                                                                                                I use on mac, and I can easily have it in my documents folder and sync it up to iCloud. I also back it up to a few other places, and since it's encrypted, I don't worry too much about people being able to peek.

                                                                                                                                                                                                The format being very simple has made it easy to hack up python scripts which allowed me to bring all my old livejournal entries, medium entries, and wordpress entries together into one diary.

                                                                                                                                                                                                • tossmeaside1 10 days ago

                                                                                                                                                                                                  It is a popular conceit to assume that anyone cares about your thoughts or that they carry some significant, intrinsic value. This happens to me all the time. It takes reflection to realize that most of the crap that people generate is just that, crap. Sure, it may be crap that can incriminate you in a court proceeding or crap that could be developed into patented intellectual property, but it is crap none-the-less. Its that tendency people have to assume things like "I got super stoned in the late 90's and sketched out designs for Photovoltaic Solar Roofing systems, that Musk guy stole my idea". No, odds are that Musk guy didn't steal shit from you. Your diary wasn't hacked, your sketches were not secretly photographed and your phone isn't bugged. Your idea was in some way obvious. In the PV example it was obvious and requires money and influence to develop, two things that if you had them you wouldn't be making claims that "so and so stole this idea" or "I invented that first".

                                                                                                                                                                                                  • oefrha 10 days ago

                                                                                                                                                                                                    For a different thought of how to do it, I self-host a Wordpress site that is essentially a diary. However, right now the scope is to keep track of recipes that I have made, if I liked them, and where I found them.

                                                                                                                                                                                                    While I could have made a notes app, this allows my fiancée to look at it, comments on it, or make her own posts to give her thoughts too (though she hasn't used it).

                                                                                                                                                                                                    I have thought about expanding it into a more general blog (technical or otherwise), I haven't gotten to that step yet.

                                                                                                                                                                                                    Thinking about it, I could make a cron service on it to ask me "what's going on" with a link to make a new post as well, and make it optionally private (so only I or who I choose can see it).

                                                                                                                                                                                                    • Dyaz17 10 days ago

                                                                                                                                                                                                      Great job. Here is what I propose to make it more secure and prevent you from being able to read anyone diary...

                                                                                                                                                                                                      I propose that each day a link/token is sent to your email. The link then ask for a password that is handled only with client side javascript and does the encryption of the data before sending it do the server. Look at what or myetherwallet is doing for client side encryption. Maybe also propose provide all the front end as opensource and provide a way for people to host their own front (a few HTML, JS files where you input the link or token sent to you by email...)

                                                                                                                                                                                                      • kossnocorp 10 days ago

                                                                                                                                                                                                        My goal wasn't to create a 100% secure diary. If you need that, you probably should not store your data in the cloud. That's unlikely that I will ever try to make it happen. But even if I would, there're so many ways to screw it over anyway, so I won't ever try to make this promise.

                                                                                                                                                                                                        However, I will consider open-sourcing it.

                                                                                                                                                                                                        Also see my comment where I addressed the privacy issue:

It's archived in my email history and in a simple, searchable web UI. It's been super useful for figuring out when I did something a few years ago, medical notes, etc.

But I'm afraid I can't fix that. When I receive an email, I associate it with the address that GMail reports to me,, and when you sign in as, the email address differs (as you might already guess). I know that I can safely remove +something but I can't be sure that it will work the same for every email service and ensure security. Please use, I won't send you anything unless you explicitly ask for it.

This is cool. Quick question. Did you pull this off in one day (after PG's tweet)? If yes, that is mighty impressive.

I built it some time ago, but I was quick to reply, so there's a chance that Paul tried the service. I'm such a fanboy, haha.

After that I just switched to using a Google Doc. The service mostly just provided me a daily reminder, but after you get into the habit it isn't hard to keep it up without that.

Edited the link manually and it worked.

Firebase generates links for me but I'll take a look at what I can do.

It looks like you're accepting everything to one generic email address, and posting via the senders address?

I used to enjoy emailing shot blog posts, and only having a few friends of mine knowing what my blog address was. It was a form of journalling that I enjoyed until they inexplicably shut the service down.

Both are web design ideals I strive for. I also want people to write more :)

Interesting. Why not just post on Facebook? It's about as public as it gets.

The idea is that you get an email each day asking about what's going on, you reply, and the service tracks your replies in a way that you can retrieve them.

Why would I write an e-mail to some random address at a domain I don't own, and pretend that it's private, when I could send it to <myalias>@<mydomain>, where it ends up on a server under my desk?
