Some privacy experts say Telegram is not secure enough False news often spreads via public groups, or chats, with potentially fatal effects. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. I want a secure messaging app, should I use Telegram? But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat.
