The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange. The contributions of premium subscribers will help improve and expand the app for decades to come, while Telegram will remain free, independent and uphold its users-first values, redefining how a tech company should operate. Telegram allows you to manage the device storage: you can choose to delete media (photos, videos, and other files) shared on the app. All files will be deleted from your device after the specified duration, but they will stay in the Telegram cloud forever, so you can re-download them when you need them again. There is also an option to delete the cache and local database.

Change Phone Numbers Large file size limit Telegram gives you an option where you can select who can see your last seen time. To configure this, go to “Settings”, “Privacy and Security” and then tap on “Last Seen & Online”. You can share it with everybody, or people in your contact list, or nobody, or add exceptions like “never share with” XYZ. My Contacts: Allow only your contacts to view your profile.

To use a proxy server in Telegram, open Settings > Data and Storage > Proxy Settings. Enable Use Proxy and you'll need to fill in all the required information to add it. You can find server info for this online if needed. Terminate old sessions Telegram’s main feature list may cross over with other apps, but there are many specific differences between it and its competitors. Here is a short list some of the major features that may push you to switch messaging apps. A further privacy blunder is that Telegram notifies your contacts when you join it — unless you don’t give it permission to access your contacts. The app doesn’t warn you it’s about to ping your contacts, and that’s a big caveat for those who want to use Telegram to keep a low profile.

Premium Chat Management Since non-secret chats and files are stored in the cloud, you can access them from any device by logging into your account. You will never have to worry about on-device storage or losing important files, but the trade-off is that you lose a bit of privacy and security.
