StackLens Privacy Policy
StackLens (hereinafter referred to as "this app") respects user privacy and handles information as follows:
1. On-device processing
StackLens lists the apps shown on your home screen and analyzes their APK files to identify frameworks and packages. All of this happens on your device. The list of installed apps and the analysis results are never sent to the developer or any third party. Results are cached on the device only, to speed up rescans, and are removed when you uninstall the app.
2. Network access
- The Flutter version table is downloaded from Google's servers (storage.googleapis.com). No information about you is sent.
- When you view package details, only the package name is sent to pub.dev's public API (operated by Google).
- Tapping an article link opens Zenn, Qiita, Reddit, Stack Overflow, etc. in your browser.
3. Ads
The free version shows ads from Google AdMob. AdMob may collect information such as the advertising ID to serve ads, measure them and prevent fraud. See https://policies.google.com/technologies/ads. Where required (e.g. in the EEA), ads are shown only after consent, which you can change in Settings.
4. In-app purchase
The remove-ads purchase is processed by Google Play. The developer never receives your payment details.
5. Children
StackLens is not directed at children under 13.
