How Telegram safeguards your information

[roseline371274]

Telegram protects user data using a combination of encryption, server architecture, privacy controls, and user empowerment features. Here's a breakdown of

1. Encryption
Client-Server Encryption (Default Chats):

Telegram uses MTProto 2.0, a custom protocol that encrypts messages during transmission between your device and Telegram's servers.

Messages are stored encrypted in Telegram’s cloud, allowing access from multiple devices.

End-to-End Encryption (Secret Chats):

Secret Chats use end-to-end encryption, meaning only you and the recipient telegram data can read the messages—not even Telegram.

Messages in Secret Chats never leave your devices, and cannot be accessed via cloud backup.

Self-Destruct Timers:

Messages in Secret Chats can be set to self-destruct after a specific time.

Once deleted, they're removed from both devices without a trace.

2. Decentralized and Secure Cloud Infrastructure
Telegram distributes its server infrastructure across multiple jurisdictions to avoid centralized control or government pressure.

Data stored in the Telegram Cloud is encrypted and fragmented, making unauthorized access extremely difficult.

Even Telegram staff cannot read user messages in Secret Chats or without decryption keys.

3. Advanced Privacy Controls
Username System:

You can communicate using a username, so your phone number remains private.

Control Over Visibility:

You can choose who sees your:

Phone number

Profile picture

Last seen & online status

Forwarded message attribution

Two-Step Verification:

Telegram supports two-factor authentication (2FA) with a password and recovery email.

This protects your account even if someone gets access to your SIM.
