Developer Description

A simple way to block access to the internet per application

NetGuard is an internet security app, which offers simple and advanced ways to restrict apps' access to the internet.

Applications and addresses can individually be allowed or denied access to your Wi-Fi and/or mobile connection. Root permissions are not required.

Blocking access to the internet can help:

• reduce your data usage
• save your battery
• increase your privacy

Features:

• Simple to use
• No root required
• 100% open source
• No calling home
• No tracking or analytics
• No advertisements
• Actively developed and supported
• Android 5.1 and later supported
• IPv4/IPv6 TCP/UDP supported
• Tethering supported
• Optionally allow when screen on
• Optionally block when roaming
• Optionally block system applications
• Optionally notify when an application accesses the internet
• Optionally record network usage per application per address

There is no other no-root firewall offering all these features.

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.

Privacy

Given NetGuard's lack of permissions, it is unlikely to collect sensitive user data, but users should still be cautious when granting access to their device's internet settings. To ensure maximum security, users should regularly review their app's internet access settings and adjust them as needed. Additionally, users should be aware of the potential risks associated with using a firewall app, such as unintentionally blocking essential services.

Tips

To get the most out of NetGuard, users should start by reviewing the app's settings and adjusting them to suit their specific needs, such as blocking access to certain apps or setting up custom rules. Users can also optimize performance by disabling the app's background data usage and limiting its battery consumption. Furthermore, users can integrate NetGuard with other apps, such as task automation tools, to enhance its functionality and create custom workflows.

This NetGuard firewall is just amazing, one of a kind. Attractive interface with an outstanding logo. I finally got a chance to install it on my Moto G&works great. The "Always on VPN" feature is a terrific extra layer of network protection. I tried installing it on my previous devices but didn't work well. Robust network protection with defined rules and notifications around the clock, you name it. So, if you really need an absolute & dependable firewall then I truly recommend NetGuard. Cheers!

Grand app! I wonder when Google will try to buy them out and destroy them. I hope they are steadfast and don't disappear like No Root Firewall did. We believe in you good folks! ✊ One great feature would be a timer ⌛ that allows an app to access network for the next X mins but then automatically loses access. Hope it is something you can bring out.
