To lock a chat go to Settings->Privacy and Security->Passcode Lock and enable it. Once you create a passcode and enable it, you will be able to lock and unlock your chats by tapping on the lock icon at the top right of the app. Telegram has a personal ‘Saved Messages’ space for each user. This is accessible from the left hamburger menu on the main screen. Users can save important messages here which will be backed up on Telegram’s secure cloud just like your chats. The Saved Messages space can then be accessed across you’re your phone, laptop and any other device where your account is logged in. Whether you no longer want to let redundant chats clutter the precious storage of your device or wish to shield your personal chats, the auto-delete timer is for you. When you set an auto-delete timer for a specific Telegram chat, all of its content including images, videos, and documents are automatically deleted after the timer expires.
Private Chats in Telegram Settings If you ever receive any cool short audio clip like a meme sound or any hilarious sound effect (also works with the sent audio) just long-press on it and choose the “Save for Notifications” option in the popup. The feature is available to Premium users starting today. To set emoji statuses, tap the Premium badge at the top of your chat list or go to Settings to change status. Press and hold an emoji to set a status for a specific duration. Telegram has a unique feature called Channels that allow you to broadcast messages to large audiences. Unlike Groups, Telegram Channels can have an unlimited amount of subscribers, and only admins have the right to post content.
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. You can review all Active Sessions and terminate any logins that you no longer use. However, Telegram only uses this encryption in calls and in its “secret chats” feature, not in regular chats. Those are only encrypted client to server. Meanwhile, WhatsApp, the supposedly less secure service, has used end-to-end encryption in all messages, calls, and video calls since 2016. Any user can upload large files and media, each up to 2 GB in size and enjoy unlimited storage in the Telegram Cloud for free. With Telegram Premium, subscribers will now be able to send 4 GB files – enough space for 4 hours of 1080p video, or 18 days of high-quality audio. Telegram Bots
Telegram offers two types of APIs for developers. Both are free of charge. 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.
