About this app

Personal Firewall by TACUNS:

Take control of what connects to your phone.

Every day, apps on your phone connect to websites and online services in the background. While many connections are necessary, others may deliver ads, track your activity, or communicate with domains you don't recognize.

Personal Firewall by TACUNS helps you see, control, and block unwanted connectionsβ€”all directly on your device. No root. No account. No subscriptions. No remote VPN servers.

Protect your privacy, reduce unwanted network activity, and decide how every app uses the internet.

TacUNS gives you complete control over your phone's internet connectionsβ€”without compromising your privacy.
━━━━━━━━━━━━━━━━

βš™ How It Works

Personal Firewall by TACUNS uses Android's built-in VpnService to create a local VPN interface that applies firewall rules on your device.

Your internet traffic is never routed through TACUNS servers.

Allowed DNS requests are resolved using your configured DNS resolver, while blocked requests are stopped locally according to your firewall rules.
