This is just a donation package for the app of NoRoot Data Firewall (https://play
It has no use if not install NoRoot Data Firewall. And after install this package, the only difference with the free version is that the app name will change to "NoRoot Data Firewall Pro". No features are added because I have put all the features in the free version.
This app will not show in the launcher. So if you want to remove it, please goto SETTINGS->APPS to remove or use some apps management tool to do that.
If you want to support the author, please buy this donation.
