Leakout - What Apps can read

Liu Dajing

About this app

Leakout is a privacy awareness tool that shows what information on your Android device may be readable by ordinary apps. It brings local device signals, runtime permission data, and installed-app permission requests into one clear view.

What Leakout shows:
- Device and system signals such as model, Android version, screen settings, battery state, storage, memory, sensors, network state, language, region, and time zone
- Permission-gated data you choose to grant, such as location, contacts, photos and videos, camera capabilities, microphone and audio device information, calendars, and nearby Bluetooth devices
- Installed app permission details, including each app's package name, requested dangerous permissions, and current grant state

Why installed app visibility is used:
Leakout's core feature is explaining the permission landscape on your device. To show which apps request sensitive permissions, it needs broad visibility into installed apps. This information is used only on your device to display permission summaries and app-level permission details.

Privacy approach:
Leakout is designed for local inspection. Scan results and reports stay on your device unless you choose to export or share them through Android's system share sheet. Leakout does not provide accounts, advertising, or background upload of scan results.

Leakout does not replace system security tools and does not block other apps. It helps you understand what local data and permission requests are visible so you can make more informed privacy choices.
