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.
Signal is a great alternative to WhatsApp. Not so much for Telegram.
