Coaching Stopwatch ("the App") is operated by HammillB ("we," "us," or "our"). This Privacy Policy explains what information the App handles, how it is used, and your choices. We designed the App to work primarily on your device. We do not require an account, and we do not sell your personal information.
Information you provide: group and runner names during setup; workout timing data (intervals, elapsed times, session state).
Stored on your device: active session data in memory; preferences via DataStore; local Room/SQLite session records (not uploaded); temporary CSV export files in cache, shared via the system share sheet you choose.
We do not collect: no account, ads, analytics, or crash SDKs sending data to us; no sale of personal information. The App does not use network access for its own operations.
You control sharing. CSV export uses Android’s share sheet. We do not receive that data unless you send it to us directly.
Notifications (Android 13+) for foreground timing; foreground service for accurate background timing.
Android backup may include App data per your device and Google settings.
Not directed at children under 13. Contact us if you believe a child provided information.
Reset/end session clears in-memory data. Uninstall removes App data (subject to backup). Shared CSV files remain where you sent them.
We may update this policy. Continued use after changes means you accept the updated policy.
