What NetGuard is for

NetGuard is an internet firewall for Android that decides which installed apps can use the internet. It needs no root access. The listing says blocking connections can reduce data use, save battery and improve privacy, and it aims the app at people who want tighter control over background network activity.

The developer describes the code as open source and says the app makes no calls home and runs no tracking or analytics. The listing also states that there are no advertisements.

Blocking apps and individual addresses

Each app can be allowed or denied access to Wi-Fi, mobile data, or both. Individual addresses can be allowed or denied as well, so an app can be cut off from one destination while still working otherwise.

The firewall covers IPv4 and IPv6 traffic over TCP and UDP, and the listing says tethering is supported, so a phone sharing its connection can apply the same rules.

Rules tied to screen, roaming and system apps

Access can be set to apply only while the screen is on, so an app can stay online while you use it and stay blocked in the background.

A separate option blocks traffic while the phone is roaming, which can matter for mobile data costs abroad. Another option blocks system applications, which are normally left running by default.

Seeing which apps connect and how much they use

NetGuard can notify you when an app tries to reach the internet, which surfaces background connections that would otherwise go unnoticed.

It can also record network usage per application and per address, so you can see which apps and destinations account for traffic over time.

Open source code and a light or dark interface

The listing describes the project as open source and says it is actively developed and supported. The interface follows Material design and offers a light theme and a dark theme.

The app's stated goals are the same as its feature list: cut data use, extend battery life and limit what apps send out, all without a root-level setup.
