Is Telegram end-to-end encrypted?

No — not by default. Default 'cloud chats' use only client-server (server-client) encryption — Telegram's servers can decrypt and store them. End-to-end encryption applies ONLY to opt-in Secret Chats, which are 1:1 only, must be started manually, are not available in the desktop/web clients, and do not sync across devices. Group chats and channels are never E2EE.

End-to-end encryption protects message contents — but not necessarily metadata. Telegram's metadata model is no. Compare it directly with RVNT, which is E2EE by default with a post-quantum handshake and no central server: RVNT vs Telegram.
