Despite Telegram's origins, its approach to users' security has privacy advocates worried. Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion.

Update March 8, 2022: EFF has clarified that Channels and Groups are not fully encrypted, end-to-end, updated our post to link to Telegram’s FAQ for Cloud and Secret chats, updated to clarify that auto-delete is available for group and channel admins, and added some additional links.
