Threema is a messenger for Android devices that focuses on the security of user data. It allows you to exchange messages, images and video files without saving them on servers as well as applying end-to-end encryption algorithms to protect information.

Create an ID

The app does not provide registration. The phone number is specified only in order to get a unique ID once. Overall, other users will not be able to see the data of the interlocutor. They will know his or her ID but not the e-mail address or phone number.

It should be taken into account that Threema requires permission to access the internal storage of the smartphone and the location. At the same time, the contacts stored on the device can not be synchronized with the utility.

Communication

Threema offers, among other things, the functionality of a standard messenger like text and voice messaging, the ability to send pictures and videos as well as the creation of group chats. Users can send each other documents in various formats, including archives.

Nuances

The difference of this messenger from most others, including Textfree, is end-to-end encryption of information and storage of user data only on the mobile device. Messages get to the server at the time of sending, after which they are deleted forever. At the same time, the data in the smartphone’s memory is encrypted, which means it is protected from unauthorized access.

Features

  • a unique ID is provided;
  • group chats, voice messages and video calls are enabled;
  • contacts are identified by a QR code;
  • app is free to download and use;
  • compatible with current versions of Android.
