@nprofile…mhy2 thanks for sharing the realities in Iran. we were not aware that Telegram is so important there. you are right that normal chats are not end-to-end encrypted.
its difficult to change platforms, but if you use user-controlled encryption software this is not necessary. you can keep using the apps you already use, encrypt the message on your phone, and only the person you choose can decrypt it. Telegram sees only ciphertext from your message (not the cleartext).
phone number stays visible though. nonetheless sensitive stuff is better protected if you leverage user-controlled encryption regardless of the platfrom you use - the platform is a business and businesses have policies, if they hold your keys, policy changes could ultimately expose folks to privacy issues down the line.
stay safe, stay private!

court records surfaced by 404 Media show what Telegram handed US authorities in one case: a user's phone number, user ID, and IP address with a timestamp.
it followed a court order.
by January, Telegram had shared data on 2253 users with US authorities. before Durov's 2024 arrest, it barely ever did.
...
you can’t hide your phone number from Telegram, but what you write can be unreadable to them, regardless of policy changes.
