Millions of people exchange messages every day throughout the world, but how many of them really know what truly happens to their messages once they send them? Will these be intercepted by third-parties?

The unfortunate truth is that we do live in a world and age in which data logging and Internet surveillance are happening.

Check out their sets of features and choose the best program for your needs. The software is equally useful if you were looking for a secure messaging software.
