- Secret Chats are device-specific and are not part of the Telegram cloud, so they can only be read on the device they started on
- Logging out destroys all of your Secret Chats
- The Secret Chat self-destruct timer applies only to messages sent after the timer is set and has no effect on earlier messages
- Telegram states screenshot detection cannot be guaranteed on some Android and Windows Phone devices, so screenshots of Secret Chats can be taken silently
- Messages cannot be forwarded out of Secret Chats
- The self-destruct timer in cloud chats covers media only, not text
