App Permission Analyzer

App Permission Analyzer is a local-first Android app for reviewing installed apps and APK files before you trust them. It explains requested permissions in plain language, detects common tracker SDK signatures, highlights risky permission combinations, and generates a simple privacy score.

The app does not request internet access. Analysis runs on the device.

Editions

Flavor	Application ID	Purpose
free	id.biz.rrndev.appanalyzer	Public free build with the Play Store upgrade CTA.
pro	id.biz.rrndev.appanalyzer.pro	Pro build for direct distribution or release builds without the upgrade CTA.

Privacy

• No internet permission.
• No app-owned ads SDK.
• No app-owned analytics SDK.
• No Google Play Services, AdMob, Play Billing, Firebase, Crashlytics, or other proprietary Google SDK dependencies.
• APK analysis uses temporary local cache only while parsing the selected file.

Tracker names such as Firebase Analytics and AdMob appear in the source because the app detects those SDK signatures in other apps. They are not dependencies of this app.

Requirements

• Android Studio or Android command-line tools.
• JDK 21, as used by the Gradle wrapper environment.
• Android SDK 36.
