NetGuard - no-root firewall


Short description
-----------------
NetGuard, the first free and open source no-root firewall for Android


Long description
----------------
NetGuard provides a simple way to block access to the internet - no root required.

Applications can individually be allowed or denied access to your Wi-Fi and/or mobile connection.

Blocking access to the internet can help:

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

Features:

• No root required
• Simple to use
• Free of charge
• Open source
• No extra battery usage
• No bandwidth reduction
• No calling home
• No tracking or analytics
• No ads
• No internet permission required
• IPv4/IPv6 TCP/UDP supported
• Optionally allow when screen on
• Optionally block when roaming
• Optionally block system applications
• Material design

There is no other no-root firewall offering all these features.
Most other firewall solutions will use extra battery and reduce the overall network speed.

Most of these features are the result of sending selected traffic to a VPN sinkhole, instead of filtering all internet traffic.
This means that advanced features, like address-based filtering (needed for hosts blocking), traffic logging, and on-demand configuration, are not possible.

Since NetGuard has no internet permission, you know your internet traffic is not being sent anywhere.
