My daughters (9yo) was conned into downloading this app while playing another game so she can get "coins". Of course they make it look very enticing to a child. Well a few days after she downloaded it, without my knowledge, her iPod started acting up. She couldnt open many apps, couldnt access her iMessage, and various other items. When she finally told me about these issues, I started to investigate. I typically dont watch her 100% of the time as to what she is downloading because Ive taught her well and have trust in her. After about a hour of frustrations I finally figured out what happened.
When you DL this app, it will ask you to "verify" your Apple ID. Hint, whenever an app asks you to do this, thats not a direct apple product, be very cautious. This app created a device management profile on her phone. Essentially taking control of her phone. They say this is how they "track" your activity. BS. This is how they attempt to steal your info. So if you delete the app and VPN, the app will still track your phone. You have to delete the actual device profile in the settings. Once you do this, you remove the permissions you originally gave the app when you first opened it.
Again, be very careful when a 3rd party app asks you to verify your ID. My poor daughter was so upset, thinking she did something wrong. I reassured her she didnt do anything. Its bad people, trying to do bad things to good, innocent people.
