Where do Skype contacts come from in Viber?

Question

Skype

I put Viber to see what kind of garbage it was, he asked me to put it on mobile first, he did. When I launched it, I saw contacts from my Skype account in the client. What the hell is this, who knows?

Answer 1

So your Skype contacts are synchronized with the phone book, and Viber synchronizes the phone book.
