Fly Free,
Chat Secure

Step-by-step: (1) All messages are end-to-end encrypted using the Signal Protocol – keys never leave your device. (2) Our servers only store ciphertext, impossible to decrypt. (3) We collect zero metadata about your contacts or conversations. (4) Open-source crypto libraries are regularly audited. (5) You can verify contact safety numbers. In short, Telegram is built so that even we cannot read your messages.

Technical breakdown: (1) Direct P2P connection whenever possible, eliminating server bottleneck. (2) Global edge acceleration nodes for relay when needed. (3) Multi‑threaded chunked uploads use your full bandwidth. (4) Automatic resumption after network drops. (5) Smart routing selects the fastest path. Combined, these give up to 300% faster transfers than typical cloud services.

Complete answer: Telegram offers native apps for Windows, macOS, iOS, and Android. Linux version is in beta. The core messaging, file transfer, encryption, and group chats are 100% free – no ads, no premium walls. In the future, enterprise features (like team management APIs) may be paid, but personal usage remains free forever.

Stepwise explanation: (1) You set a timer from 1 to 60 seconds before sending. (2) After the recipient reads it, the timer runs down. (3) Once expired, the message is permanently wiped from both local storage and server caches. (4) No backup, no recovery – not even by forensics. This ensures absolute ephemerality for sensitive data.

Detailed privacy commitment: (1) We only require a phone number or email for account creation – no real names. (2) We never sell or share any user data. (3) No advertising, so no tracking. (4) Option to disable crash reporting. (5) Full GDPR & CCPA compliance. You own your data; we are simply the tool that keeps it safe.

Straight facts: No artificial cap. Single file up to 50GB is supported. Total transfer volume per day is unlimited for personal use. We designed the protocol to handle huge design assets, 8K video dailies, and massive datasets. For even larger files, the app automatically splits and reassembles.

Security-first sync process: (1) Each device generates its own identity key. (2) Sync uses end-to-end encrypted tunnels. (3) To add a new device, you must scan a QR code from an already trusted device – no blind trust. (4) Messages are encrypted locally before upload to cloud relay. (5) You can remotely revoke lost devices instantly.

Recovery procedure: (1) Because of zero‑knowledge architecture, Telegram cannot reset your password directly. (2) You can reset using your linked email/phone to generate new keys – but old encrypted history will be lost (by design). (3) We strongly recommend saving your recovery phrase during setup. (4) Without that phrase, no one can access your account, ensuring security even against us.

Group encryption explained: (1) Telegram uses the Signal Protocol for groups as well. (2) Each group has a unique shared key that rotates automatically when members join/leave. (3) Past messages are never decryptable by new members. (4) Group admins can manage permissions, but cannot read private one-to-one messages within the group context. Security scales perfectly.

Support channels: (1) In-app “Help & Feedback” sends logs directly to our engineers. (2) Email support@Telegram.com – we reply within 24 hours. (3) Join our Discord community for real-time help. (4) Extensive knowledge base and video tutorials on our website. Our team is committed to transparent, fast assistance.
