This Privacy Policy explains how the "Minirefu" iOS/Android app ("the App") handles user information.
1. Information We Collect
Schedule data (train/bus times, milestones, etc.): stored only on your device. Nothing is sent to any external server, and there is no account system.
Photos of timetables taken with the camera: used for the timetable scanning feature. Text recognition happens entirely on-device using Apple's/Google's built-in frameworks; images and recognition results are never uploaded to any server.
Advertising-related information: the free version uses Google AdMob to show ads. If you grant tracking permission (App Tracking Transparency), an advertising identifier (such as IDFA) may be used to personalize ads. If you decline, ads will still be shown but may be less relevant.
Purchase information: the premium unlock is processed entirely through Apple's StoreKit (In-App Purchase). The developer never receives or stores your payment details.
The App has no login or account system, and the developer does not directly collect personally identifying information such as your name or email address.
2. How We Use Information
To provide the App's core features (displaying schedules, notifications, and widgets)
To display ads in the free version
To verify premium purchase status
3. Third-Party Sharing
We use Google AdMob (Google LLC) to serve ads. Please refer to Google's own privacy policy for how its SDK handles information. The developer does not sell any collected information to third parties.
Schedule data and appearance settings are stored only on your device, in storage shared between the app and its widget. If you use the data export feature, where the exported file is saved or shared is entirely up to you.
5. Children's Privacy
The App is not directed at children, and we do not knowingly collect personal information from children.
