NetGuard – Simple & Powerful No-Root Firewall for Android

If you want complete control over which apps can access the internet on your device — without rooting — NetGuard is one of the most trusted open-source firewall apps available. It uses a local VPN interface to block or allow connections on a per-app basis, giving you full oversight of your mobile data and Wi-Fi usage.

NetGuard helps improve privacy, save battery life, reduce data usage, and prevent apps from sending information in the background. With a clean interface and advanced options like logging, filtering, and notification controls, it’s an essential tool for anyone who values transparency and security.

Privacy & Security

NetGuard does not collect or share your personal data.

Because it uses a local VPN interface (not a remote VPN), your data never leaves the device or passes through third-party servers.

NetGuard is designed with privacy, safety, and transparency at its core.
