Permission Scanner

Permission Scanner gives Android users a readable view of what each installed app can access. It combines package-level permission scanning, local risk analysis, app comparison, APK pre-install checks, privacy timelines, and exportable reports in one Flutter app.

The app is designed to be transparent: scanning happens through native Android APIs, analysis runs locally, and the codebase keeps permission explanations and risk rules easy to inspect.

Features Installed app scanner - reads installed packages through a native MethodChannel and returns permissions, install source, system app status, SDK data, trackers, services, receivers, and app metadata. Privacy risk scoring - calculates a 0-100 privacy score and classifies apps as safe, medium, dangerous, or critical based on dangerous permissions and high-risk behavior signals. Security dashboard - summarizes overall device risk, permission exposure, risky apps, and recent permission changes. App detail view - shows permission groups, risk signals, install details, trackers, and developer-level permission data. Permission justification - maps common app capabilities to required permissions and helps spot access that does not match an app's purpose. APK scanner - scans an APK file before installation and reports permissions, trackers, packers, overlays, accessibility use, background behavior, and spyware indicators. App comparison - compares two installed apps across permission count, dangerous permissions, trackers, background services, auto-start behavior, internet data risk, and open-source status. Privacy tools - includes a permission library, timeline view, report export, privacy policy, and project transparency links. Smart caching - uses Hive and package fingerprints to avoid unnecessary full rescans when the installed app set has not changed. Local alerts - optionally sends notifications when high-risk permission patterns are detected.
