Warden: Firewall & Anti-Spy

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 spyware, and the room for hidden trackers. • Next morning: a recap of what your first day blocked and who tried to track you. 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. • Your own website rules — block or allow any site, switch a rule off and on without deleting it. • Live network log — every lookup, by app and company. • Tracker blocking in every app, not just the browser — community lists or your own rules. • Encrypted DNS — DoH presets including a family filter, your own endpoint, or strict mode. • Packet capture — record what crosses Warden into a .pcap file, free. • Deep Inspection (Warden+) — every connection every app makes, live. • Profiles, Schedules, screen-off rules, trusted Wi-Fi and roaming (Warden+). • Focus lock (Warden+) — unblocking waits a delay you choose, so a weak moment can't undo your plan. ANTI-STALKING & SPYWARE — FREE FOREVER • Spyware warnings — blocks and alerts on contact with 5,000+ servers used by state-grade spyware such as Pegasus, Predator, Candiru and Paragon, from Amnesty International, Citizen Lab and the MVT project. Ad networks that deliver spyware are blocked too. • Stalkerware check — known stalkerware, Android spyware used against journalists and activists, and apps quietly holding spying-level access. Checked on every new install. • What changed? — a daily record of apps installed, removed and given new access. • Tracker radar — AirTag, Tile, SmartTag, Chipolo, and camera glasses such as Meta Ray-Ban nearby. • "Is it following me?" — a warning when an unknown tracker stays with you. Make AirTags and compatible trackers play a sound. • Background guard, evidence pack for police or a lawyer, ultrasonic beacon and GPS-spoofing checks. • Camera & mic — see which apps can watch or listen. • Spyware & targeted-ads checklist — security-update age, a restart reminder, and steps to remove your advertising ID. CLEAR ANSWERS • Connection check — is it Warden, your Wi-Fi or your DNS provider, 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 • Warden's own traffic: DNS lookups to the resolver you choose, list downloads, the optional AI model, and camera lookups only while the map is open. Warden+ list downloads include your Play purchase token. FREE, WITH AN OPTIONAL UPGRADE Free forever: the firewall, lockdown, website rules, the last 24 hours of the network log, packet capture, tracker blocking, block-new apps, Travel, and every anti-stalking and spyware feature above.
