Secret chats 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. 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.

Furthermore, you can view how much Mobile or WiFi data you have consumed so far. Just tapping on “Data Usage”, and it will show you “Bytes sent” and “Bytes received” of individual file types. If you want to send big files, Telegram has much of the competition beat with support for up to 2GB files. Meanwhile, WhatsApp’s limit is a measly 100MB, WeChat’s limit is also 100MB, and Skype’s limit is 300MB. Telegram files are also stored in the cloud, so you can access them from other devices. Possibly the biggest disadvantage Telegram has over more popular messages is simply that: popularity. Despite its hundreds of millions of fans, Telegram is still leagues behind WhatsApp, Facebook Messenger, and WeChat in active monthly users. Here, Telegram will give you some information about what happens when you change your number. Basically, all your messages will be moved to the new number and your new number will be automatically added to all your existing Telegram contacts, barring the blocked contacts. It’s way easier then re-sharing your new number with everyone. To change the number, tap on the “Change Number”, enter the new number and follow the process on your screen.

“Privacy” itself isn’t a particularly attractive product feature in online services. It can be nebulous: We can’t always feel or understand it, and sometimes it’s only when privacy is taken away that we take it seriously. There's also a hidden menu that appears when you long-press on the Send button. Choose Schedule message to delay sending until a time in the future. You can also tap Send When Online to send the message when the other person is next active on Telegram. That would be lead to provide more benefits when accessing your Telegram chat from different devices you have. Send Uncompressed Media without Changing the File Extension

While all Telegram chats are client-server encrypted, default chats are still stored on Telegram's servers. This conveniently allows you to access your messages on multiple devices, but it might raise privacy concerns. Another thing to keep in mind is that selling your data isn’t at the core of Telegram’s business model. According to Telegram’s FAQ page, the company is funded by its founder and CEO Pavel Durov, not through advertising or data collection and sharing.
