What the app uses, and why
| Data | Why | Where it goes |
|---|---|---|
| Location (precise or approximate, only if you allow it) | To check official alerts, radar, lightning and forecasts for your location, and to show your position on the map | Coordinates are sent from your device directly to US government weather services (National Weather Service, NOAA) and to our map provider to load the right data. We do not receive or store them. |
| Saved places and your shelter plan | To watch places you choose and show your plan during a warning | Stored only on your device. Place coordinates are sent to the weather services above to check alerts. |
| Place searches | To find a city or town you type | The text you type is sent to a geocoding service (Photon, by Komoot) based on OpenStreetMap. |
| Settings and alert history | To remember your choices and show recent alerts | Stored only on your device. |
| Usage counters (for example, how many times the app was opened) | To choose a good moment to ask for a rating and to improve the app | Stored only on your device in this version. They are not sent to us. |
| Advertising data (advertising ID, device information, approximate location from your IP address, ad interactions) | To show and measure ads in the free app | Collected by Google AdMob. See below. |
Location
The app asks for location permission the first time you use it. You can decline and search for a city instead. In this version, Stormkeeper uses your location only while the app is open. You can change the permission at any time in your phone’s settings.
Advertising
The free app shows ads through Google AdMob. Google and its partners may collect and use your device’s advertising ID, device information, IP address (which indicates approximate location) and how you interact with ads, to show ads, limit how often you see them, measure them and prevent fraud. Where required, the app asks for your consent first, and you can change your choice in the app’s settings under privacy choices.
Learn more: How Google uses information from apps that use its services. You can reset or delete your advertising ID in Android settings under Privacy → Ads.
Stormkeeper never shows ads while a watch or warning is active for your location.
