This app isn't in any of our charts yet.
Fixes a startup glitch that could skip restoring Deep Inspection, stops the on-device AI from repeating itself, and adds DNS details to support reports so connection problems can be fixed faster.
Firewall for every app + stalkerware & AirTag detection. Runs on your phone.
Take back control of what your phone talks to — and find out what is watching you. Warden is a no-root privacy firewall and anti-stalking toolkit that runs on your phone. No account, no analytics, no ads. Your rules, logs and tracker history stay on the device unless you back up or share them. IN THE FIRST MINUTE • See which companies your apps are contacting right now. • Cut any app off the internet with one tap. • Check your phone for stalkerware and the room for hidden trackers. WHY IT ASKS FOR VPN PERMISSION Warden uses Android's VpnService to build a local firewall. The tunnel begins and ends on your phone — Warden runs no VPN server and routes none of your traffic through us. ━━━ CONTROL YOUR NETWORK ━━━ • Per-app firewall — separate Wi-Fi and mobile rules that switch automatically. • Lockdown — default-deny: only the apps you allow get online. • Block new apps — a new install gets no network until you say so. • Live network log — every lookup, allowed or blocked, by app and company. • Data use per app — what each app sent and received today and this week. • Tracker blocking — community lists or your own rules; allow one domain for one app. • Encrypted DNS — DoH presets, your own endpoint, or strict mode. • Travel — tracker blocking, block-new and the guard, switched from Home. • Deep Inspection (Warden+) — every connection every app makes, live. • Profiles, Schedules, screen-off rules, trusted Wi-Fi and roaming (Warden+) — your setup changes by itself: on a timer, when the screen is off, on a Wi-Fi you named, or abroad. ━━━ ANTI-STALKING — FREE FOREVER ━━━ • Stalkerware check — scans your apps for known stalkerware and apps quietly holding spying-level access, and checks every new install. • What changed? — a daily record of apps installed, removed and given new access, with a warning when a new app gets notification, accessibility or device-admin access. • Tracker radar — AirTag, Tile, SmartTag, Chipolo and ALPR camera gear nearby. • "Is it following me?" — a warning when an unknown tracker stays with you across places. Make an AirTag beep to find it. • Background guard — keeps watching with the app closed. • Evidence pack — export tracker history to share with police or a lawyer. • Ultrasonic detector — hears the inaudible beacons some ads use to link devices. ━━━ CLEAR ANSWERS ━━━ • Home shows the one thing that needs you: a stalkerware match, a tracker with the guard off, a setting that weakens protection. • Connection check — is it Warden or your network, and how to fix it. • AI explanations (Warden+, optional) — plain-language answers from a small model that runs entirely on your phone. ━━━ PRIVATE BY DESIGN ━━━ • No account, no analytics, no ads. • Warden's own traffic: your DNS lookups to the resolver you choose, list downloads, the optional AI model download, and camera lookups only while the map is open. Warden+ list downloads include your Play purchase token so the server can confirm your subscription. ━━━ FREE, WITH AN OPTIONAL UPGRADE ━━━ Free forever: the firewall, lockdown, network log, data use, tracker blocking, block-new apps, Travel, the stalkerware check, What changed?, tracker radar, anti-stalking alerts, evidence export and the ultrasonic detector. Personal-safety alerts are never paywalled. Warden+ adds the curated list we recompile daily, Deep Inspection, tracker intelligence (history and watched places), the camera map, custom DNS with strict mode, WebRTC leak protection, Profiles and Schedules, screen-off, trusted Wi-Fi and roaming rules, per-app domain blocks and on-device AI explanations. $2.99/month or $24.99/year after a 7-day free trial, or buy once and keep it forever. Cancel anytime in Google Play. Requires the on-device VPN permission, plus Bluetooth and Location to scan for nearby trackers. Usage access is optional, only for per-app data use.
