How secure are Telegram Chats?

All Telegram data is encrypted and cannot be deciphered by your ISP, network administrator or random hackers.

Cloud chats are stored encrypted in the Telegram Cloud, and the keys needed to decipher this data are kept in other data centers in different jurisdictions. This way, local intruders or engineers can't access this data, and several court orders from different jurisdictions are required to force us to give up anything. Thanks to this structure, we can ensure that no single government or block of like-minded countries can intrude on people's privacy and freedom of expression.

Secret chats are meant for people who want even more than that. They use end-to-end encryption, so there is no way to decipher your data without accessing your device. It means you don‘t even need to trust Telegram when you use Secret Chats — their secrecy is guaranteed client-side and anyone can check the source code of Telegram clients.

If you are concerned about security in general, there are other important precautions you could take. Consider protecting your account by enabling 2-Step Verification and setting up a strong passcode to lock your app, then it won’t be possible to access your chats by stealing your device or even by intercepting your SMS code. You will find both options in ‘Settings’ under ‘Privacy and Security’.
