Firewall

Important:
1. The app works as a VPN, and it is not possible to use it with another VPN, as only one VPN connection can be active.
2. The app does not allow you to select only Wi-Fi or mobile internet access; both Wi-Fi and mobile internet are blocked.
3. The app does not have a connection log.
The app only allows certain apps to access the internet, or it does not allow anyone to access the internet at all. It's very easy to set up: there's a switch next to the app, and if it's on, the app has internet access; if it's off, it doesn't.
