How to Check if Your Phone Number Is in the Huge Facebook Data Leak

I had a similar case, but I don't absolutely distrust unfamiliar calls.

I think it's impossible to avoid data leaks while surfing on sites like Facebook, Twitter, etc. It seems to me that such sites use special applications such as http://numbertrackerpro.com . For me, this is unacceptable, of course, when your personal data leaks into the network and every user can easily use them. I think there is a simple solution to this question - using VPN applications through which you can hide your location and data from other users. Try to take my advice and save your data if you value them so much. Good luck!
