Kelvin
Privacy Policy
The short version
- No ads, no analytics, no tracking and no accounts.
- We don't run servers that collect your data, and we never sell data.
- Your location is used only to fetch weather for where you are, and sharing it is optional.
- Your places and settings stay on your device.
Who we are
Kelvin is a weather app for Android and iOS made by Offbeat Applications ("we", "us"). This policy explains what information the app uses and why.
Location
If you grant location permission, Kelvin reads your device's approximate or precise location. Your device sends those coordinates directly to the weather services listed below, only to get forecasts, radar and alerts for your area. We never receive your location.
Location permission is optional. You can deny it and search for places by name instead. You can change the permission at any time in your device settings.
Third-party services
Kelvin gets its data from these providers. Each request includes only what's needed to answer it.
| Provider | Used for | What's sent |
|---|---|---|
| Open-Meteo | Forecasts, air quality, place search | Coordinates, or the place name you search |
| RainViewer | Radar images | Map tile requests for the area you view |
| OpenFreeMap | Radar base map (Android) | Map tile requests for the area you view |
| Apple Maps | Radar base map (iOS) | Map tile requests for the area you view |
| US National Weather Service | Official alerts in the US | Coordinates |
| Google News | Local weather headlines | The name of the place you're viewing |
Like any web request, these services can see your IP address. Their own privacy policies govern how they handle it.
Data stored on your device
Your saved places, settings (such as units and theme) and Kelvin+ subscription status are stored only on your device. Home screen widgets read the same local data. All of it is deleted when you uninstall the app.
Kelvin+ subscriptions
Kelvin+ is an optional subscription. Purchases are processed by Google Play or the Apple App Store under their own terms and privacy policies. We never see your payment details. To cancel, manage your subscription in Google Play or your Apple ID settings.
Notifications
If you turn on weather alerts, Kelvin checks for warnings in the background using the same weather services and shows them as notifications. No data is sent to us.
Children
Kelvin is not directed at children under 13, and we don't knowingly collect information from children.
Your choices
- Turn location permission off at any time in your device settings.
- Turn weather alerts off in Kelvin's settings.
- Uninstall the app to remove all data stored on your device.
Because we don't hold personal data on any server, there's nothing for us to export or delete.
Changes to this policy
If this policy changes, we'll update this page and the date at the top.
