NetGuard

NetGuard is possibly the first free and open source no root firewall for Android.

Features

• No root required
• Simple to use
• Free and open source
• No calling home
• No ads

Usage

• Enable the firewall using the switch in the action bar
• Allow/deny Wi-FI/mobile internet access using the icons at the right side of the application list

Permissions

• ACCESS_NETWORK_STATE: to check if the device is connected to the internet through Wi-Fi
• RECEIVE_BOOT_COMPLETED: to start the firewall when starting the device

Frequently asked questions

(1) Can NetGuard protect my privacy?

Not really, since the firewall cannot be started right after starting your device and because updating firewall rules require momentarily turning off the firewall.

(2) Can I use VPN applications while using NetGuard?

If the VPN application is using the Android VPN service, then no, because NetGuard needs to use this service too and Android allows this to just one application at a time.
