Firewall AI Downloads & RevenueFirewall AI - No Root · Google Play

Choose which apps go online. Firewall AI is a no-root firewall for Android that lets you block internet access per app, manage Wi-Fi and cellular data separately, and see where your apps connect. Keep the connections you need and restrict those you do not.

An app may contact advertising, analytics or other services in the background. Firewall AI brings that activity into view and combines your app rules with local, AI-assisted connection analysis.

Control internet access per app
• Allow or block Wi-Fi, cellular data and roaming separately.
• Keep selected apps on Wi-Fi only.
• Disconnect an app from the internet without putting your phone offline.
• Turn the firewall on or off from Android Quick Settings.

Keep messaging and navigation connected while limiting internet access for other apps. Restrict online access for tools that work offline, or review a new app before giving it ongoing access. Rules can be changed whenever your needs change.

See where your apps connect
The connection log shows outgoing connection attempts with the app, destination IP address, country and time, plus host or domain details when available. Data counters help you spot unexpected network activity. Tags and filters make it easier to find the connections you want to review.

An unfamiliar destination is not automatically a threat. Use the log to understand an app's behavior and decide which connections fit the way you use it.

AI-assisted filtering with Deep Detective™
Deep Detective helps identify suspicious connection patterns on your device. The intrusion prevention system, or IPS, uses filter lists to help block known malicious and tracking destinations. The filter lists cover more than 10 million domains.

This adds destination-based filtering to your own app rules: control which apps can connect and use selected filters to limit unwanted destinations.

DNS settings and tracker control
Choose a DNS provider or configure a custom DNS server. DNS-based filtering can help block requests to listed advertising, tracking and phishing domains. Combine DNS settings with app rules to reduce unwanted connections.

Results depend on the selected filters and how an app connects. Not every ad or tracking method can be blocked.

Start with app control. Add PRO when needed.
Use the basic firewall to manage app internet access. Firewall AI PRO adds enhanced filter lists and IPS PRO for more advanced destination filtering. Compare the features, purchase options and terms shown in the app before upgrading.

Why Android asks for VPN permission
Firewall AI uses Android's VpnService to direct network traffic through a local interface for filtering on your device. It does not send that traffic through an external VPN server and does not change your location or hide your public IP address.

Android supports one active VPN service per user profile. Firewall AI therefore cannot run alongside another active VPN in the same profile.

Local control, clear privacy
The app has no ads. Your
