About
Telegram Messenger is a cloud-based instant messaging app that syncs across all your devices—phones, tablets, and computers—so you can start a message on one device and finish it on another. With over 1 billion active users, it supports group chats up to 200,000 members, unlimited file sharing (up to 2 GB per file), and encrypted cloud storage of your entire chat history. Messages use 256-bit AES encryption, 2048-bit RSA encryption, and Diffie–Hellman key exchange. Secret Chats offer end-to-end encryption with optional auto-delete, and the app works on weak mobile connections. It includes photo and video editing, customizable themes, bots, and an open sticker platform.
