DGZFirewall Android Firewall

DGZFirewall : With per-app network control by DGZStudios

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.
