Privacy Policy

Last Updated: November 2026

Multi-Model Weather (“the App”) is developed and maintained by Mustafa BAŞARAN. The App is completely free to use and ad-free. It has no user accounts, and the developer does not run any server that collects your data. This policy explains what the App does with your information. The App’s About and Terms & Conditions pages are available inside the App.

1. Summary

No account or sign-up is needed. Your location is used only to fetch weather, radar and place names from the third-party services listed in section 4. No advertising, no analytics or tracking SDKs, no profiling, and your data is never sold. Your settings and saved places stay on your device and are never sent to the developer.

2. Information the App uses

Location: With your permission, the App uses your device’s approximate or precise location (GPS and network-based) to show local forecasts, run the radar comparison, and power notifications and widgets. You can also choose places by searching for a name or entering coordinates. If your precise location is not available, the App may estimate an approximate location from your IP address using the services ipwho.is and GeoJS.

Nearby points for the radar check: To compare weather models with radar, the App also looks at eight points roughly 50 km around your location. These points are calculated on your device. Their coordinates are sent to Open-Meteo to obtain model data, and the radar map tiles covering the area are requested from RainViewer.

Search text: Place names you type into the search box are sent to Open-Meteo’s geocoding service.

Information stored on your device only: The App stores on your device: your saved places, notification settings (types, quiet hours, sensitivity), language and theme, activity preferences, recent forecast snapshots used to detect forecast changes, a short history of radar readings for your area (location rounded to about 10 km, kept for up to 72 hours), and tutorial flags. This information is never sent to the developer. Clearing the App’s data or uninstalling the App removes it.

3. Notifications, background checks and widgets

Notifications are optional and require your permission. When enabled, the App periodically checks the forecast (about every 30 minutes, although Android may delay this) for up to three saved places you have turned notifications on for. These checks run on your device through the Android WorkManager component, and each check downloads forecast data from Open-Meteo. Device identifiers or personal tokens are not transmitted to any external push notification server.

Home-screen widgets refresh forecast data for the places chosen in the widget settings in the same way. You can turn notifications off in the App or in your phone’s system settings.

4. Third-party services

To work, the App connects over HTTPS to the following independent services. They receive the information needed for the request, together with standard connection details such as your IP address.

These services have their own privacy practices, which the developer does not control. For Open-Meteo, see Open-Meteo Privacy; for RainViewer, see RainViewer Privacy Policy.

5. Advertising, analytics and tracking

The App does not contain third-party advertising networks (e.g., Google AdMob) and does not integrate behavioral analytics or tracking SDKs (e.g., Firebase Analytics, Facebook SDK). Your data is not used for profiling and is never sold.

6. Sharing of information

The developer does not receive your location or other personal data, so there is nothing for the developer to share. The only information that leaves your device is what is sent to the services listed in section 4 so that the App’s features can work.

7. Retention and your choices

You can withdraw location and notification permissions at any time in your phone’s settings. You can remove saved places or turn off notifications inside the App. Clearing the App’s data or uninstalling it erases everything stored on your device. How long the third-party services keep the requests they receive is governed by their own policies.

8. Children

The App is not directed at children, and the developer does not knowingly collect personal information from anyone.

9. International transfers

The third-party services above may operate servers in countries other than your own, so the requests the App sends to them may be processed outside your country.

10. Your rights

Because the developer does not collect or store your personal data, there is no personal data held by the developer to access, correct or delete. If you live in a region with data-protection laws (for example the GDPR, the UK GDPR or Türkiye’s KVKK) and have a question or request, please contact the developer using the details below. For data held by the third-party services, please contact them directly.

11. Changes to this policy

This policy may be updated from time to time. The latest version is always published on this page, with the “Last Updated” date at the top.

12. Contact information
