After the events of yesterday, I decided to convince my close friends to move to other platforms. I already use Telegram and it's been superb to Messenger, WhatsApp, IG messaging, etc. in every way.However, I want to see if it's possible to create "micro-messenger" apps; basically, a messenger app that you only use with a handful of people[1]. I want to have full control over the server side, so please don't say "just use Signal".Given Telegram's open-source base code, is it possible to create a decent messaging app that goes down when you also go down? (e.g., when you die, or when you just want to terminate it).[1] I think if you're going to say something or share photos/files that are personal, chances are you are already close to your recipient. And there aren't many of those people.
