This security-focused messaging app allows you to register a unique username so that people can message or add you to groups without necessarily knowing your phone number. This way, you can keep your number private. To start a Secret Chat, you can either tap on the option in the hamburger menu and select a contact to start the chat. Alternatively, you can go to an existing chat, tap on the top bar for the user’s information and scroll down to find the “Start Secret Chat” option at the very bottom of the page. Once you tap on the option, the other person will have to accept your invitation to initiate the Secret Chat. That’s far from saying Telegram will protect you from all privacy terrors the online world presents — you should check out our Android privacy guide for a broader look at that. Telegram just offers a good marriage of popularity and security for those with concerns over other messaging apps.

If you select the Scheduled option, the auto-night mode will kick in at a pre-defined time which you can change. If you select the Automatic mode, the auto-night mode will start depending on the ambient light. You can slide the slider to select at what percentage of the ambient lighting do you want the night mode to start at. Personally, I prefer the scheduling option, however, you can use the one you like. On iOS, Telegram offers you the flexibility to choose a default browser where the links are opened. Though Safari is set as the default option, you can set other browsers like Chrome, Firefox, or Microsoft Edge as the preferred choice. On Android, tap the three-dot Menu button in the top-right of any Telegram chat and choose Mute notifications. On iOS, tap the contact or group name at the top of the screen and choose Mute. Then you can choose to mute the chat for various periods of time, or forever. Share Live Locations

Custom Notification Sounds You can surely delete messages that you have sent, but did you know that Telegram has brought a new feature that lets you delete messages sent by other users too. That’s kind of weird, but this feature is for users who prioritize privacy over everything. To use this feature, just select the received message and tap on the “delete” button. Now, select “Also delete for X” and tap on “Delete”. The message will disappear from both ends without leaving any trace.
