NetGuard is a free and open-source Android firewall that provides comprehensive control over your apps' internet access without requiring root permission. It works by creating a local VPN to filter all outgoing traffic directly on your device, ensuring that no data is sent to external servers. Core Firewall Features
: Optionally allow connections only when the screen is on, or block them entirely when roaming.
: Because it uses a local VPN, users should disable battery optimization for NetGuard to prevent the system from closing it in the background.
