🛡️ PROTECTION SCORE
Get a real-time security score combining permission audits, special access checks, device diagnostics, and battery health — your device's security posture at a glance.

🔐 APP PERMISSION AUDITOR
See exactly which apps access your sensitive data across 10 categories:
• Location & Background GPS
• Camera & Microphone
• Contacts, Accounts & SMS
• Phone Logs, Storage & Photos
• Calendar, Body Sensors & Bluetooth
Spot which apps have permissions declared vs. actually granted — and revoke what you don't trust.

Findings grouped by app, prioritized by severity. For each risk:
✓ Fix Now — go directly to the relevant setting
