Technical information:

In our application we use WebRTC. It is a technology which we use to communicate with other people in real time, with audio or video communication.

With XCall, you can make both single and group calls. We use RSA encryption to ensure the security of your messages. Only the user who generated the key pair (public and private) will be able to decrypt the messages sent to them.

All information used in the application (user information, contacts, chats) is stored in a database, access to which is encrypted with the user’s PIN.
