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”.

Telegram also includes useful security options in this menu, which differ in name slightly on Android and iPhone. Use Passcode Lock to keep people from reading your chats.
