End-to-end encryption is only available for “Secret Chats”—a different chat mode which must be manually enabled. Secret Chats are device-bound, not synced across devices, and their content can only be seen by the two participants.

How safe is Telegram's MTProto encryption protocol?

The use of distributed data storage by Telegram means multiple court orders from different jurisdictions are needed to access user data.
