Can Telegram be used on PC? Plus, if you’re using the “secret chats” feature, you’re getting the same level of end-to-end encryption. On top of this, users can’t forward or screenshot messages in secret chats, and messages can be programmed to self-destruct. Deleting a message also deletes it for everyone on the service, and users have the option to delete not just their own messages, but other users’ messages, too. It’s also worth mentioning that all chats are encrypted, even if not end-to-end encrypted. 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.

You can use this to, for example, keep your personal and professional lives separate on Telegram without having to use another messenger app. To change the number you use with Telegram, open Settings (which is inside the left menu on Android). On iPhone, in the next menu, tap Edit in the top-right corner. This step isn't necessary on Android.
