The InternetGuard Data Saver Firewall is the only application that has a no-root firewall and still offers all these features. This application creates an illusion of being on top of the data usage chart because InternetGuard uses your device’s VPN package to create a firewall. As every data packet sent or received by your apps passes through the VPN, all the incoming and outgoing data traffic gets attributed to InternetGuard. The good part, however, is that the InternetGuard Data Saver Firewall application now comes with its own Data Usage feature which will allow you to check data usage for each app. To view the usage, you choose Data Usage from the home screen.
This app is based on a VPN interface, which is the only way to implement the firewall on no-root devices. It works as the proxy between the common apps and the servers. The app doesn’t steal your data or send even one bit of its own.
