Don't use telegram

• It is centralized system. Sources avaiable for client only (not for server). So you cannot create alternative server.

• By default, content of all messages is avaiable for server owner, because used client-to-server encription only. To make client-to-client connection and hide contents of your messages from server owner you need to create special "secure chat" session. ATTENTION: Model of encription for "secure chat" are NOT explained. You should see the sources without any guides if you want to understand how it works. One thing i've understand: developers never used words: "client key".

"Secure chat" sources for Android: https://github.com/DrKLO/Telegram/blob/master/TMessagesProj/src/main/java/org/telegram/messenger/MessagesController.java#L4680

• Telegram require you phone number for registration:

• Durov's social network "VK" one year ago was blocked me access to my own account - require my phone number to continue use it. I cannot remove my account without entering my cell number. This social network became closed for all users without cell phone: http://nypa.ru/index.php?/archives/211-nachalos.html (Russian)

From this time i'm in diaspora.

So we have open-source client with client-to-server encription. We have server which we cannot control, cannot change, cannot select other Telegram-server. Privacy controlled by Telegram owners.

For example: Mozilla Firefox - is open-source client with client-to-server encription. Facebook - is the server which we cannot control, cannot change, cannot select other Facebook-server. Privacy controlled by Facebook owners.
