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.
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, and which list blocked it.
• Data use — per-app use; data-cap and background-burn alerts with Warden+.
• 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.
• Deep Inspection (Warden+) — every connection every app makes, live, with packet capture.
• Profiles, Schedules, screen-off rules, trusted Wi-Fi and roaming (Warden+) — your setup changes by itself.
• 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 servers used by state-grade spyware such as Pegasus and Predator (Amnesty International's list).
• Stalkerware check — known stalkerware 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 and Snap Spectacles 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 detector, GPS-spoofing check and a magnetometer sweep for hidden GPS trackers.
• Camera & mic — see which apps can watch or listen.
• Spyware & targeted-ads checklist — security-update age, an optional restart reminder, and steps to delete your adverti━━━ CLEAR ANSWERS ━━━
• 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 ━━━
• Warden's own traffic: your DNS lookups to the resolver you choose, list downloads, the optional AI model download, and
