**Effective date:** 28 April 2026
Bay Zero ("the app") is a companion app for the Garmin Approach R10
launch monitor. This policy explains what data the app handles, how it
is used, and the choices you have.
This is a short policy because the app is simple: **all of your shot
data stays on your phone.** Bay Zero has no user accounts, no servers,
and no analytics. We do not sell, share, or transmit your shot data to
anyone.
## 1. Who we are
Bay Zero is developed by NomNom Apps. You can reach us at
nomnom.mobileapps@gmail.com
## 2. Data the app handles
### Stored on your device only
- **Shot data from your R10:** ball speed, club speed, launch angle,
spin rate, spin axis, club path/face, smash factor, carry, apex,
descent angle, and timestamps for every shot you record.
- **Sessions and clubs you create:** session names, dates, club lists,
club ordering, and the structured-session results (for example Gap
Test or Speed Training).
- **Settings:** distance unit (yards/metres), audio and text-to-speech
preferences, environment values, and tilt-calibration baselines for
your R10.
This data is held in a local database on your device. It never leaves
your phone.
### Sent to a third party
- **Approximate location (latitude / longitude)** is sent when the app
looks up local weather for the ball-flight model. The lookup uses
**Open-Meteo** (https://open-meteo.com), a free weather service that
does not require an account or API key. Bay Zero does not store your
coordinates after the lookup completes. You can turn this off by
disabling weather auto-detect in Settings and entering temperature,
altitude, and humidity manually.
### Not collected at all
- We do not collect your name, email, phone number, or any identity
information.
- We do not collect device identifiers, advertising IDs, or analytics.
- We do not use crash-reporting or telemetry SDKs.
- We do not use the microphone or camera.
## 3. How the app uses the data
- Shot data is used to show your live shots, keep session history,
calculate gapping and club averages, and render the ball-flight
visualisation.
- Location is used only to look up local weather for accurate carry
and apex calculation. The app does not record or upload your
location history.
- Bluetooth is used only to communicate with your R10.
## 4. Permissions the app requests
The app asks only for permissions it actually uses:
- **Bluetooth (scan / connect)** — to find and talk to your R10.
- **Location (fine and coarse)** — Android requires location
permission for Bluetooth Low Energy scanning, and the app uses your
coordinates to look up local weather.
- **Vibrate** — for haptic feedback when shots register.
- **Foreground service (connected device)** — keeps the Bluetooth link
alive while a session is active so you do not miss shots.
You can revoke any of these in your phone's system settings; some
features will not work without them.
## 5. Data sharing
We do not sell, rent, or share your data with anyone. Open-Meteo
receives your coordinates as part of a weather lookup and is governed
by its own privacy policy (https://open-meteo.com/en/terms#privacy).
## 6. Data retention and deletion
All data lives on your device. To delete it:
- Delete individual sessions or clubs from inside the app, or
- Uninstall Bay Zero — your operating system removes the entire local
database with it.
There is no server-side data to request, export, or delete.
## 7. Security
Because all data stays on your device, its security depends on your
device's own protections (screen lock, encryption, etc.). The app does
not transmit shot data over the network.
## 8. Children
Bay Zero is not directed at children under 13. We do not knowingly
collect data from children.
## 9. Changes to this policy
If we ever change how the app handles data — for example, if an
optional cloud sync feature is added — we will update this policy and
revise the effective date above. Continued use of the app after a
change means you accept the updated policy.
