I seriously doubt this App’s main purpose is to steal your personal information.
It takes a long time to review and the reason for that is they carefully review everyone. I use my Facebook account to sign in and everything about me is real. I have all my pictures in raw file. And then, couple days after approval, they blocked my account said that my account is fack. I wrote them an email with all the proof that it’s real me. I have a steady job with good income; i didn’t sell anything whatsoever. They just blocked me said my account is fake(same reply again) and then no reply since. I seriously doubt this App’s main purpose is to steal your personal information.
