Privacy Policy
Effective 28 July 2026 · Sprocket Science · com.sprocketphysics.claero.air
Claero.air calculates local air density and density altitude from a nearby weather observation and your phone's barometer. This policy says exactly what it collects, why, and who else sees it.
What we collect
| Data | Why | Notes |
|---|---|---|
| Precise location | Measuring speed, distance and elevation during a run, resolving the local acceleration of gravity, and finding the nearest weather observation. | Not linked to any identity. |
Permissions the app asks for
| Permission | What it is for |
|---|---|
| Location | Precise location while you use the app. |
| Motion & Fitness | The accelerometer, gyroscope and barometer. iOS keeps the barometer behind this permission; no fitness or activity data is recorded. |
| Bluetooth | Connecting to a Bluetooth weather meter, if you use one. |
Every one of these is optional at the system level. Declining a permission disables the feature that needs it and nothing else.
Who else receives data
- Weather data. Your coordinates are sent to the US National Weather Service (weather.gov) and Open-Meteo (open-meteo.com) to look up conditions near you. They are not sent with any identifier, and we do not store them.
Keeping and deleting your data
There is nothing to delete. This app has no account and no server: every setting lives on your device, and deleting the app removes all of it. Observations are fetched fresh each time and are not retained by us.
Children
Claero.air is not directed at children under 13, and we do not knowingly collect personal information from them.
Your rights
Depending on where you live, you may have the right to access, correct, export or delete the personal data we hold about you. Email support@claerodynamics.com and we will action it.
Changes
If this policy changes materially we will update the effective date above and, where the change affects what we collect, note it in the app's release notes.
