9月1日 的 Warden: Firewall & Anti-Spy 應用程式分析

Take back control of what your phone talks to — and find out what is watching you. Warden is a no-root privacy firewall and counter-surveillance toolkit that runs entirely on your phone. No account, no analytics, no ads, no data collection. Your rules, your logs and your tracker history never leave the device. IN THE FIRST MINUTE • See the domains your apps are contacting right now. Most people are surprised. • Cut any app off the internet with one tap. • Scan the room for Bluetooth trackers that should not be there. WHY IT ASKS FOR VPN PERMISSION Warden uses Android's VpnService to create a local, on-device firewall. That is the only way an app without root can control which apps reach the network. The tunnel begins and ends on your phone — Warden operates no VPN server and routes none of your traffic to us or to anyone else. ━━━ CONTROL YOUR NETWORK ━━━ • Per-app firewall — cut any app off with one tap, with separate Wi-Fi and mobile-data rules that switch automatically. • Lockdown mode — default-deny: nothing reaches the internet except what you allow. • Live network log — every domain your apps look up, allowed or blocked, labelled by app. • Deep Inspection — watch every connection every app makes, in real time. See who your apps really phone home to. • Encrypted DNS (DoH) — lookups travel over DNS-over-HTTPS, so your network cannot read the domains you visit. • Privacy filtering — subscribe to community domain lists, or write your own block and allow rules. • Weekly report and home-screen widget — how many tracker lookups Warden stopped this week, day by day. ━━━ SEE WHO IS WATCHING ━━━ • Surveillance Radar — scan nearby Bluetooth for hidden trackers: AirTag, Tile, SmartTag, Chipolo and ALPR camera gear. • "Is it following me?" — Warden warns when an unknown tracker stays with you across several locations, and keeps that history on your phone only. • Make it beep — force a detected AirTag to play its sound so you can physically find it. • Background guard — keeps watching with the app closed. • Ultrasonic beacon detector — listens for the inaudible 18-20 kHz tones some ads and stores use to link your devices. ━━━ PRIVATE BY DESIGN ━━━ • No account, no analytics, no ads, no data collection. • Honest about its limits — Warden tells you plainly what it can and cannot do. • Warden's only outbound traffic: your own DNS lookups to the resolver you choose, anonymous list downloads, and — only while the Surveillance Map is open — anonymous camera lookups against public OpenStreetMap data near you. ━━━ FREE, WITH AN OPTIONAL UPGRADE ━━━ The firewall, lockdown, network log, privacy filtering, tracker radar, anti-stalking alerts and the ultrasonic detector are free forever. Personal-safety alerts are never behind a paywall. Warden+ adds the curated list we recompile daily, Deep Inspection, tracker intelligence (history and watched places) and the camera-map layer. $2.99/month or $24.99/year after a 7-day free trial — or buy it once and keep it forever. Cancel anytime in Google Play. Warden is a privacy and data-control tool. It lets you decide, per app, what may use the network, and helps you spot devices that may be following you. It does not modify other apps. Requires Android's on-device VPN permission for the firewall (no traffic is routed off your phone), plus Bluetooth and Location to scan for nearby trackers.
