Firewall Security AI - No Root

Your apps should connect on your terms. Firewall AI is a no-root firewall for Android that lets you control internet access per app, review outgoing connections and block unwanted traffic. Manage Wi-Fi, cellular data and roaming without rooting your phone.

An app can connect to advertising, analytics and other services in the background. This Android firewall makes that activity easier to understand, so you can choose what stays online instead of giving every app unrestricted internet access.

APP INTERNET CONTROL

• Allow or block Wi-Fi, cellular data and roaming separately for each app.

• Keep selected apps on Wi-Fi only.

• Block internet access for apps that do not need an online connection.

• Turn the firewall on or off from Android Quick Settings.

Keep messaging, navigation and other essential apps connected while restricting the rest. Review new apps before allowing ongoing access, or tighten roaming rules when you travel. Your internet blocker works around the rules you choose.

CONNECTION LOG AND DATA INSIGHTS

Review outgoing connection attempts with app names, destination IP addresses, countries, times and available host or domain details. Data counters help you spot unexpected network activity. Tags and filters make it easier to focus on the apps you want to inspect.

Look at where a new app connects, consider its purpose and decide whether that access is needed. Use visible connection details to make informed choices.

DNS FILTERING AND TRACKER BLOCKING

Choose a DNS provider or set up a custom DNS server. DNS-based filters can help block listed advertising, tracking and phishing domains. Combine destination filtering with per-app rules to reduce unwanted requests without removing the apps you use.

The results depend on your selected filters and how an app connects. Not every ad or tracking method can be blocked.

AI-ASSISTED NETWORK CHECKS

Deep Detective™ helps identify suspicious connection patterns. The intrusion prevention system, or IPS, uses filter lists to help block known malicious and tracking destinations. Filter lists cover more than 10 million domains, including malware, tracking and spyware destinations.

Firewall AI focuses on outgoing connections. It does not scan files for viruses or provide protection against incoming network attacks.

LOCAL FILTERING, CLEAR BOUNDARIES

Traffic is filtered on your phone through Android's VPN interface, not routed through an external firewall VPN server. No root or system modifications are required. The app has no advertising, and connection logs and rules stay on your device. See the privacy policy for licensing and other online functions.

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.

Firewall AI does not change your location or hide your public IP address. Android allows one active VPN service per user profile, so you cannot use it alongside another active VPN in the same profile.

MORE ADVANCED FILTERING WITH PRO

Firewall AI PRO adds enhanced filter lists and IPS PRO. Review the available features, purchase options and terms in the app to choose the option that fits your needs.

GET STARTED WITH YOUR KEY APPS

Install Firewall AI, approve Android's VPN request and set your first app rules. Check the connection log, then refine your settings as you learn how your apps connect.

Blocking internet access can interrupt messages, syncing and other online features. Allow the app again or restrict it to Wi-Fi when that better matches your needs. You can adjust your rules whenever you need to.
