BackflowLogger does not collect, store, transmit, or share any personal data. Your device and test data stays on your device.
BackflowLogger collects no data whatsoever. Specifically:
BackflowLogger stores your backflow device information (location, serial number, install date) and test records (test dates, results, pressure readings, photos) locally on your device using IndexedDB. This data never leaves your device and is not accessible to us or any third party. You can export your data as CSV at any time, and you can delete all data from within the app.
All app data is stored locally on your device using IndexedDB and localStorage. This includes device records, test history, photos, settings, and preferences. None of this data is synced, uploaded, or shared.
BackflowLogger may request permission to access your camera to attach photos to test records. Photos are stored locally on your device using IndexedDB. Photos are never uploaded to any server.
BackflowLogger may request permission to send local notifications (test expiration reminders). These notifications are generated entirely on your device. No notification data is sent to any external service.
If you purchase BackflowLogger Pro, the transaction is processed by our payment provider. We do not store your payment information. The payment provider's privacy policy applies to the transaction itself.
BackflowLogger works entirely offline after initial installation. No data is sent to any server at any time during normal use.
BackflowLogger uses no third-party analytics, advertising, or data collection services.
BackflowLogger does not collect any data from anyone, including children under 13.
If we ever change this policy, we will update the date above.
