Telegram is a messaging app with a focus on speed and security, it's super-fast, simple and free. You can use Telegram on all your devices at the same time – your messages sync seamlessly across any number of your phones, tablets or computers.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc.), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. Plus, you can share videos up to 2GB, send multiple photos from the web, and forward any media you receive in an instant.

You do need a phone number to create a Telegram account, but after setup, you can control who sees it. You can also use a username to connect with others without sharing your number. Some users use virtual numbers or secondary SIMs during registration for additional privacy.

Telegram offers some privacy and security features, but it is not as private by default as many people assume. Only "Secret Chats" use end-to-end encryption. Regular cloud chats are encrypted between your device and Telegram servers, which means Telegram technically has access to the content. Users looking for maximum privacy should use Secret Chats.

Telegram regular chats are stored on Telegram's servers, so no manual backup is needed – they sync automatically across devices. However, Secret Chats are device-specific and cannot be backed up or synced. If you want a local copy of your chats, you can use Telegram Desktop, which allows you to export chat history, go to: Settings > Advanced > Export data.
