  • They diverge on capability: Cal.com covers Custom booking pages, Telegram covers Cloud-based messaging.

Telegram

  • End-to-end encryption applies only to Secret Chats; private and group Cloud Chats use server-client encryption, so Telegram holds the data
  • 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
