PrivacyGuard - Mobile Security App-Analysen für 10. Oktober

PrivacyGuard is your on-device privacy watchdog for Android — it watches what your apps actually do, and gives you the tools to stop what you don't like. No cloud. No account. No telemetry. Every scan, every score, and every block happens on your phone. WHAT IT DOES Privacy Score See a single 0–100 score and A–F grade for every app on your device, based on real observed behavior — not just permissions on paper. Sensor Monitor Know the moment an app touches your camera, microphone, or location — especially in the background. Background sensor access triggers an instant alert. Network Monitor A local VPN tunnel inspects DNS and TLS SNI traffic to reveal which trackers and ad networks every app talks to, and how much data it sends them. No content is intercepted — just hostnames. Block Ads & Trackers Turn on ad and tracker blocking device-wide with one switch, or fine-tune it per app — some apps break when trackers are blocked, so you can allow just the ones you need. App Risk Scanner Flags dangerous permission combinations, sideloaded apps, and other red flags across everything installed on your device. On-Device AI A machine learning model scores app behavior for anomalies — no data ever leaves your phone for this analysis. Action Center Ranked, actionable recommendations: which app to fix first, and exactly what to do about it. Per-App Kill Switch Cut off a misbehaving app's internet access entirely, with one tap. YOUR DATA STAYS YOURS PrivacyGuard doesn't talk to the internet except to protect you. There's no backend server, no analytics SDK, no ad network inside PrivacyGuard itself. Every score, every alert, and every blocked domain is computed and stored locally on your device. Free. Open blocklists. No account required
