Description
Control internet per app - without rooting your phone. Firewall Security AI - No Root is a no-root Android firewall (firewall for Android / app firewall / internet blocker) with DNS privacy and on-device analysis. See which apps try to go online, review outbound connections in real time, and allow or block them in seconds - before your data leaves your device.
Many apps and some system services connect quietly in the background to analytics, ad networks, telemetry endpoints or unknown hosts. Firewall Security AI makes this transparent: every connection attempt is logged with the app name, host/domain, IP address, country, protocol and timestamp. If something looks wrong, block it with one tap.
PER-APP INTERNET CONTROL • Allow or block Wi-Fi, cellular data and roaming per app • Make specific apps fully offline when they do not need network access • Quick rules like "Wi-Fi only", "Always block" or "Allow only what you trust" • Quick Settings tile to toggle the firewall in one tap
DNS PRIVACY + CUSTOM DNS DNS is often the entry point for tracking and unwanted requests. Choose a secure DNS provider or set a custom DNS. DNS-based blocking can help reduce tracking, ads and phishing. Combine DNS + per-app rules for stronger control - no root required.
SMART BLOCKING (OUTBOUND) • AI Firewall & Deep Detective™ help you spot suspicious or unknown connection patterns • IPS focuses on blocking known outbound threats using filter lists with 10M+ domains covering malicious, tracking and spyware targets • Reduce unwanted destinations while keeping the apps you actually need
CONNECTION LOG & INSIGHTS • Clear log with app, host/domain, IP, country, protocol and time • Data counters to identify "chatty" apps and unexpected traffic • Tags and quick filters so you can find what matters fast
REAL-WORLD USE CASES • Public Wi-Fi: block new or unknown apps until you review their destinations • Travel: keep roaming strict and allow only essential apps • Social apps: reduce background tracking without uninstalling • Games and streaming apps: set "Wi-Fi only" to avoid unexpected cellular usage • Quick privacy check: install an app, see where it connects, then decide
ANDROID VPN SERVICE This anti spy firewall app uses the Android VPN Service to route traffic to itself so that it can be filtered on-device instead of on a server. Important: this is not a location-changing VPN. Android VPN is used as a technical interface for local traffic filtering. Android typically allows only one VPN at a time - switch if you use another VPN app.
PRIVACY BY DESIGN No ads. No account required. Rules and logs stay on your device. Firewall Security AI focuses on visibility and control of outbound (device-to-internet) connections to help reduce unwanted data sharing. If an app stops working after blocking, simply allow it again or set it to "Wi-Fi only".
COMPATIBILITY Works on modern Android devices and is Android 15 compatible. Uses the official Android VPN framework for local filtering - no root, no risky modifications.

GET STARTED IN 3 STEPS 1) Install and enable the personal firewall VPN 2) Set rules for your top apps (Allow / Block / Wi-Fi only) 3) Choose your DNS and filter lists for your privacy level
NO OVERPROMISING This is a personal firewall focused on outbound visibility and blocking. It does not claim to provide inbound network protection.

Great app, been using it a long time but only once in a while I have difficulty with getting it to connect to my phone because it seems, even though I have connections on automatic, when I put on dns, it says can't connect to dns service a lot of times and IDK why? Can you help?

Firewalls Security Protocols for the people who are sharing connections ideas for this mobile phone to be able to make sure that the firewalls strength to be able to get even stronger than ever before to confirm that the firewalls' strength to Protocols are being abided by.

My favorite dialer has all the Aesthetics that I am looking for. I don't butt dial anybody because it shows me information first. But it has lost the ability to hold a button over other apps that I can answer the phone by. And it also seems to have lost the ability to dial the phone to place a phone call. So it is falling behind the Android requirements for good dialer. I am looking around to see which one that I want to use for a replacement.

Last warning Google! The lifetime version I once owned through G-Play has been "refunded" by Protect Star! I own the Firewall AI and Antivirus AI Pro versions through the Protect Star website, I use a Microsoft email for that acc! Forced use of the changed name version of the Protect Star Firewall AI app through G-Play is entrapment of fraud!!! Fix this issue or be sued for conspiracy to entrap me for fraud!! Remove the Lifetime version of the Protect Star Firewall AI from this Gmail medially!

I think this is not an AI-powered firewall app; it's just a basic firewall features app. I know many filters are locked behind a paywall, but if you check out Net Guard Firewall, it has so many features unlocked, including some important ones. For example, if I install Protect Star Firewall and accidentally visit a malicious website, and a hidden app is installed through that site, there is no automatic blocking protection in Protect Star Firewall.

Mr Developer u didn't get my point. My point is for example Adguard dns blocking same ads while Us ng android private dns settings use, n if I turn it off n use ur app inside dns settings using adguard dns from there no ad block for the same, so obviously it's your app failure, hope u understand my point?? I don't say anything without rigorous testing!!😡
