Telegram messages are encrypted. Telegram uses end-to-end encryption technology to ensure users have a secure and confidential communication experience. End-to-end encryption means that messages can be encrypted on the sending device and decrypted only on the receiving device. This does not mean that messages are sent and stored encrypted on Telegram servers. In Telegram, end-to-end encryption is only used for private chats called "secret chats". Secret chats are encrypted chats of users with a specific device and key. In such chats, messages can be temporarily stored on servers, but stored encrypted and messages can only be decrypted with the correct key.

However, in normal chats it is transmitted over Telegram servers and stored encrypted on the servers. In such chats, messages pass through servers without end-to-end encryption, so Telegram officials may technically have access to view encrypted messages. If you want to use a fully end-to-end encrypted messaging platform, you can choose other messaging apps that offer end-to-end encryption like Signal or WhatsApp instead of Telegram's private chats.
