But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access.
