The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange. In order to protect your personal information, Telegram automatically terminates your old sessions after 6 months. However, you can choose to get rid of the old sessions sooner in order to further boost security. 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.
Unlike other cloud-based solutions, Telegram’s personal space has infinite storage. You can also send all kinds of files here. However, note that each file you send must be sized lesser than 1.5GB. You don’t need a separate image/video editor to make your photos/videos more compelling. You can do it right in the telegram app using its intuitive interface.

Telegram is free to use and supported by its founder and CEO Pavel Durov. The company began employing new monetization methods in 2021, including a Telegram Premium subscription service, but the core business of chatting will remain free for everyone. To enable or disable this service, go to “Settings”, “Notification and Sounds”, and swipe down to the “Other” section. You will also find a “Repeat Notifications” option, which you can select as per your convenience. If you're verified on at least two social networks, you can verify your group, channel or bot. However, Message history is the most revealing part of your phone when it comes to private information. I hope you may have some experience with it?
