Focus on Network， Firewall WITHOUT ROOT. Applications can individually be allowed or denied access to your Wi-Fi and/or mobile connection by VpnService locally.

FocusNet app uses the VPNService to direct internet traffic locally, thus avoiding a remote VPN server. This approach negates the necessity for root access while setting up the firewall.When the FocusNet is running, it processes both 'allowed' and 'blocked' traffic locally, ensuring that only the 'allowed' traffic reaches its destination
