DGZFirewall Android Firewall

DGZFirewall — Network Firewall & Traffic Monitor Take back control of your Android's internet access. DGZFirewall gives you a powerful, easy-to-use firewall that decides exactly which apps can reach the internet — and shows you everything they're trying to connect to in real time. PER-APP FIREWALL Block any app from accessing the internet with a single tap. Whether it's a game sending telemetry, a utility phoning home, or an app you simply don't trust — DGZFirewall cuts its connection instantly. Allowed apps keep working normally. You decide what goes through and what doesn't. REAL-TIME TRAFFIC MONITOR Watch your device's network activity as it happens. Every connection attempt — inbound and outbound — is logged with the destination IP address, protocol (TCP/UDP), direction, and timestamp. Tap any entry to open Connection Details and see the full picture: where the connection was going, which app made it, and the geographic location of the destination IP. IP GEOLOCATION Blocked connections show you the city, region, and country of the destination IP — so you know exactly where your apps are trying to reach. No guessing. No digging through logs manually. ALERTS DGZFirewall flags unusual inbound connections and repeated blocked attempts so you stay informed without watching the traffic log manually. Check the Alerts tab at any time to review flagged activity. ALWAYS-ON PROTECTION Turn it on once and forget it. DGZFirewall automatically restarts after a device reboot, keeping your firewall rules active without any manual steps. New apps installed while the firewall is on are automatically blocked until you choose to allow them. LOCAL-ONLY. PRIVATE BY DESIGN. DGZFirewall uses Android's built-in VPN API to create a local network filter entirely on your device. Your traffic is never routed through an external server. DGZ Games never receives your connection logs, blocked app lists, or any personal data. Everything stays on your phone. The VPN key icon in your status bar is normal — it simply means the firewall is active and monitoring traffic locally. FREE TO USE DGZFirewall is completely free. No account required. No subscription. No paywalls. Supported by non-intrusive banner ads via Google AdMob.
