FlöFuel is a cycling nutrition app for iPhone and Apple Watch. Your privacy is important to us. This policy explains what data FlöFuel accesses and how it is handled.
FlöFuel does not collect, store, or transmit any personal data to external servers. There are no FlöFuel servers. All data stays on your device.
FlöFuel can optionally read your body weight from Apple HealthKit to calculate personalized hydration targets. This is entirely optional — you can enter your weight manually instead. FlöFuel never writes data to HealthKit. Weight data is used only for on-device calculations and is never transmitted off your device.
FlöFuel requests location access at city-level accuracy only (kCLLocationAccuracyKilometer) to detect local weather conditions for hydration adjustments. Your location is used ephemerally — it is not stored, logged, or transmitted to FlöFuel servers (there are none).
FlöFuel uses two weather services to determine temperature for hydration calculations:
api.open-meteo.com to retrieve current temperature. Open-Meteo is a public API that requires no authentication, no user account, and no user identifier. See Open-Meteo's terms for details.Ride timestamps, fuel intake events, and GI comfort ratings are stored locally on your device using SwiftData (SQLite). This data never leaves your device.
FlöFuel syncs programs and session state between iPhone and Apple Watch using Apple's WatchConnectivity framework and App Groups. All communication is local, on-device only.
FlöFuel does not include any analytics frameworks, advertising SDKs, crash reporters, or tracking tools of any kind. We do not track your usage of the app.
FlöFuel does not require you to create an account, sign in, or provide any personal information.
Since FlöFuel does not collect any personal data, there is nothing to share with third parties.
FlöFuel does not knowingly collect any information from children under 13.
All FlöFuel data is stored locally on your device. Uninstalling FlöFuel completely deletes all app data. There is no server-side data to request deletion of.
If we update this privacy policy, we will post the revised version at this URL. We encourage you to review this page periodically.
