I mostly text on Signal with disappearing messages so I wouldn't be able to do this. Most people are fine with disappearing messages at 4 weeks, but a few people like to keep their chats forever.

Tbh I wish all messaging apps worked like this. While it’s kind of cool to make charts like this, the privacy implications are pretty terrible for keeping conversations forever.

A data breach on an IM app would be one of the most devastating leaks ever. And there’s just not that many legitimate use cases for keeping all history. If someone tells you something important you can make the effort to move it to their contact or notes in your phone.

  • If the chat is truly E2E there is no way a data breach can happen on the server side. The same applies if the app is only saving chat logs locally. [1]

    Now, if the threat scenario is someone implanting a compromised version of the IM app on every device out there, and siphoning data from the device itself, then it's a completely different scenario.

    [1] although this could be intercepted by an attacker compromising the IM servers, if the app is not distributed/P2P

    • Logs are stored on local devices and many people back them up in whatever cloud (majority not encrypted).

      You or the other person could lose the device and someone could use your PIN/password (something as simple as shoulder surfing while you use it). There could also be a leak in whatever cloud service you're using, or the data could get subpoenaed because of some dumb law that gets passed, some rogue employee, etc. It's a huge liability no matter how you look at it.

there's a tool for extracting chat history from signal desktop, you could build a plaintext and attachment archive with that if it runs regularly on your pc and appends new chats from the last run.

  • I'd be pretty angry if I found out someone I chatted to on Signal was running a service to workaround my message expiry choice and archive my messages. And breaking that trust just to run it through an LLM?

Do you keep separate notes for things like recommendations or addresses? I often dig through my chats to find them.

  • Yeah I use NotesNook for big notes or projects.

    I also use the Note to Self which is built into Signal and appears just like any other conversation. I use that for temporary stuff like addresses and keep it clean.
