Yeah, they seem to put a lot of energy into esoteric features, when the app is in serious need of some quality of life improvements. I donate a tiny monthly sum to the project and honestly feel conflicted about how effectively it's being used.

Or maybe chat history just isn't that important overall. I can do backups just fine on android but have only used that once. I wouldn't be too concerned if I lost all of my chats, as I've already read them.

The core security and privacy features are what's most important. I'd prefer they keep those as the top priority.

i have disappearing messages set for 2 weeks by default.

i can't understand why anybody would need a 5 year history of their chats 🤷

i remember using icq 🙊 i would have encyclopedic chat histories if i kept them. Chat is chat. Wind in the air. You hear it, then it's gone.

A lot of people use this as an SMS replacement, cool story that you don't use it that way, but there are plenty of people that do. And the fact that it can also take over and send normal SMS and not just signal means people have more tightly integrated it.

Uh, it does not and has not sent SMS for a good while now.

So use more than one app. Signal is secure. Retaining data for years is not.

It's very clear that way.

It's hard to tell what chats you'll want to retain, so people will just use the other app...

On the other hand, I usually know ahead of time when I don't want a certain conversation saved. Even if I don't, I can delete a message for everyone right after something is sent. That stuff won't get backed up.

Retaining data for years is not.

I don't see why this is the case? Sure deleting your data completely is always more private than keeping it, but why would it be that much worse keeping it. If the information is important, people will keep it in other forms instead (ex. insecure chat app, personal notes, text messages).

I search through my chats pretty often, both on Signal and things like FB Messenger. Sometimes I want a link that was sent, sometimes I want to review something we talked about, or sometimes I need to figure out when something happened and I can do that by checking when I talked about it with a close friend.

It's ok if you don't use it, but it's important to a lot of people

are you 14? People have a lot of reasons to archive their communication: forgotten conversations, random details, family, memories, relationship, business,

But I can understand why an edgy teenager won't have any of those.

Even backups on android could be simpler, such as automatically storing the backup file on a cloud drive. Right now we need to set that up manually with a separate app.

Also while history isn't important for you, it IS important for other people. If I couldn't do the bare minimum with backups, I'd probably have dropped signal. I know some friends didn't take up Signal just because of chat history reasons (iOS, couldn't set up cloud backups on android, etc.)

Like the checking for messages notification on Android, I use notification reminder app to remind me of missed messages (ring every 5 minutes) and sometimes randomly in the middle of the night Signal creates a notification that says "checking for messages" and it stays there for a while getting my notification remjnder to think there is an unread message and ringing in the middle of the night. I can't turn off notifications I might need to be waken up for important stuff.

You could use Tasker to make an automation that checks what the notification's content is, but it's just an ugly workaround

I think it might have a good reason to post that notification. Android kills apps that are doing background operations for too long without also posting a persistent notification about it.

You can disable the notification channel corresponding to that kind of notification, though. I'm not totally sure if that way your other app won't see it either, but I think it's worth a try.

One stupid thing I've come across...you can either choose per contact or overall what the chat bubble color is, but when I do so, MY chat bubbles are colored and everyone else's are grey. That seems backwards to me. If I want to do "Pink is this person, blue is that person, green is that person" it ends up going "wait whose end of the conversation is this again?"

Does someone have a patent they're trying not to infringe?
