Some privacy experts say Telegram is not secure enough READ MORE Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. 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. Despite Telegram's origins, its approach to users' security has privacy advocates worried.
