Your privacy and security are our top priority. Telegram uses cutting-edge encryption and open protocols to keep your conversations safe from hackers, governments, and surveillance.
Secret Chats use end-to-end encryption with no server access. Only you and the recipient can read the messages. The encryption keys are stored on your devices and never leave them.
Our custom-built protocol combines AES-256 symmetric encryption, RSA 2048 encryption, and Diffie-Hellman key exchange. It has been independently audited and verified by security researchers worldwide.
Set messages to automatically delete after a chosen time period. Once the timer expires, messages are permanently removed from both devices and cannot be recovered by anyone.
Protect your account with an additional layer of security. Two-step verification requires a confirmation code from an existing session before allowing login on new devices.
Telegram's infrastructure is distributed across multiple jurisdictions. Encryption keys are stored in different countries from the data they decrypt, requiring multiple court orders to access any content.
All Telegram client applications are open source. Anyone can review the code, verify the encryption implementation, and build their own version. Transparency builds trust in security.
Verify the encryption of your Secret Chats by comparing visualizations of the encryption key with your chat partner. If the images match, your chat is guaranteed to be secure.
Secret Chats notify you when the other party takes a screenshot. This transparency feature helps maintain trust and accountability in your most sensitive conversations.
Telegram was built from the ground up with security in mind. Unlike other messaging apps that bolt on encryption as an afterthought, Telegram's architecture is designed to protect your data at every level of the stack.
Regular cloud chats are encrypted between your device and Telegram servers using the MTProto protocol. This means your data is protected from network attacks, ISP surveillance, and man-in-the-middle attacks while in transit.
Secret Chats go a step further with true end-to-end encryption. The encryption keys never leave the participating devices, and Telegram servers cannot decrypt the messages even if compelled to do so by legal authorities.
Telegram does not sell your data, show you ads based on your conversations, or track your behavior for marketing purposes. Your message history, contacts, and personal information are not monetized in any way.
We believe that privacy is a fundamental human right. That is why Telegram offers features like anonymous forwarding, hidden phone numbers, username-based communication, and the ability to delete messages for everyone without a trace.
Telegram regularly hosts cryptography competitions and publishes the results. We encourage security researchers to audit our code and protocol implementations. Our bug bounty program rewards researchers who find vulnerabilities.
We publish transparency reports and cooperate with legal authorities only when properly served with court orders that meet our strict criteria. We will always fight for our users' right to private communication.
