Hi, German here.

How about not storing any information at all? Nothing to give, problem solved. Just like Signal.

I seriously don’t understand why people use Telegram instead of Signal. Any reason! The app doesn’t solve any privacy problem, default chats are unencrypted, keeps personal info. App should be dead already or turned into a dating app because it’s clearly not seriously privacy fucused.

You can install Telegram with f-droid, and it works well on a degoogled phone. Signal forbids alternate clients and is not on f-droid. It's thus just not an option.

> Signal forbids alternate clients

Which might be due to their E2E encryption?!?

No, it's a management decision and not a technical limitation.

Strange, I have Signal on a de-googled Puxel 2 runnibg ClayxOS...

But I guess you have an original Signal APK installed, not an alternative client that connects to Signal servers.
