All required permissions are described here: https://github.com/M66B/NetGuard/blob/master/FAQ.md#user-content-faq42

NetGuard uses the Android VPNService to route traffic to itself, so it can be filtered on-device instead of on a server. Only one app can use this service at the same time, which is a limitation of Android.

Ratings and reviews

Been using this for years but I don't know what you've done to it. I updated it recently and it won't work. Keeps turning itself off. Items I've allowed will become blocked and vise versa. Went to phone settings to keep it on at all times. Stays on now but blocks everything single thing from the internet even though I have quite a few apps on green (allowed). Had to turn it off just to leave this comment. Button stays red even when on. Used to be green. Other issues.

If you get this app, get the version from GitHub. It has rest of features that aren't allowed on version from Google Play, because Google doesn't like apps that can filter out their data collection and ad traffic. I am super grateful for the ability to filter out tracking sure traffic, ad servers, and other suspicious and unnecessary traffic from my browser.

Simply a great app. Block those individual annoying apps that continue to reinstall, connect to the net, track, display adds, update automatically, reduce privacy, use power & resources, and prevent optimum performance.... without rooting. FYI: Have also been testing the email app and to date, it has performed remarkably well. VERY impressive.
