APK Permission & Privacy Scanner — Audit Android APKs in browser RAM for spyware permissions & ad tracking SDKs
Inspect Android APK binaries directly in your browser. Unpacks manifests, checks dangerous camera/audio/GPS permissions, and detects tracking SDKs.
Step-by-Step Client-Side Workflow
1. Central Directory Inspection: Parses the ZIP archive structure of your .apk file in WebAssembly/JS memory without uploading the file.
2. Permission & SDK Fingerprinting: Scans for dangerous permissions (audio recording, background GPS, SMS reading) and known advertising tracking SDKs.
3. Privacy Score Calculation: Generates an overall safety score from 0 to 100 with an itemized risk breakdown and markdown export.
Why Use VaultTools Zero-Upload Architecture
Detect Spyware Before Installing: Verify whether a downloaded APK requests unnecessary access to your microphone, camera, or SMS before side-loading.
Identify Hidden Ad Trackers: See which analytics and profiling SDKs (AdMob, AppsFlyer, Facebook) are embedded inside the app code.
No Root or Emulators Needed: Static analysis runs instantly in any modern web browser without needing Android Studio or complex command-line tools.
Frequently Asked Questions
Does scanning an APK execute its code?
No. This tool performs static bytecode and manifest inspection only. The app is never run, so malicious code cannot execute on your system.
What makes a permission "Dangerous"?
Android classifies permissions that directly impact user privacy (such as microphone, camera, contacts, and precise GPS) as dangerous permissions that require explicit user runtime grants.
