I feel save


I’ve recently downloaded that app and I find it really convenient. It has no size restrictions for photos and it is very good for me. Design is simple but I still like it. Now I use video calls for communication with my family, by the way, voice and image quality is high, it is good for someone who likes photography as much as me. Also, that high security level makes it reliable, I find it important for messenger.

For safe communication

Eve Eaton

I don’t think the government or anyone else is following me, but still I would like to keep my personal data safe from potential online snoopers. That is why I installed this app. I don’t quite understand what encryption is, but it sounds convincing and I think it works.

Safe and multifunctional

John Shepard KO

The main feature of this app is the protection of personal data. It's difficult to verify, but so far I haven’t read the news that this app is unsafe. In the rest, there are all the functions that should be in a good messenger. Special thanks for video calls.
