Registration and interface

Just specify that here, as in VIPole Secure Messenger, screenshots of confidential windows do not work. In this case, it does not help even the Android emulator. Log in to the program, by the way, with this or it is impossible, as is necessary to issue SMS-confirmation is entered automatically, without manual input PIN.
 

By the way, and the data is not stored on the server. Signal thus can be used as the main application for SMS / MMS, and thus are all protected messages. It is noticeable that the approach to safety in a serious guys.
 

After a more detailed study of the program, I was surprised and happily found the same settings in the slider, which allows screen shots (thanks for that developers). The problem of describing the application somehow understood.
 

Now the interface. It is spartan and a bit like Facebook Messenger. In the bottom right of the screen is the key to activate the chat. As mentioned above, in the messenger communication occurs only within the system, that is, your partner must leave the room at Signal. Actually, according to him, it is necessary and contact.
 

in addition, the application provides a built-in search for a subscriber, it is possible to organize a group (group chat, who immediately is in the protected mode) .
 

Among the other features – Import SMS database system, that is, the program is ready to take under his wing before unencrypted messages. You can also create an encrypted backup “esemesok” and shared in the same restore (on the chat it does not apply, excluding any possibility to crack the conversation).
 

Security Overview options

SMS and MMS
 

Signal application can be used to work with the default SMS. This activates the forced request for delivery of each message sent (does not work with all operators), and also includes support for sending SMS and MMS messages via Wi-Fi.
 

you can also manually drive settings for MMS, that convenient, because the default of the program resets.
