EclipseGPS app — last updated: 1 August 2026
EclipseGPS computes eclipses on your device. Your location is never sent to the app publisher and never stored on a server: it is used only for the local computation and stays in the phone's memory. The app creates no account, measures no audience and collects no usage statistics.
Three exceptions, detailed below: advertising, city search and map display require exchanges with third-party services.

| Data | Purpose | Legal basis | Where it goes |
|---|---|---|---|
| GPS location (approximate or precise) | Compute the local circumstances of an eclipse: obscuration, contact times, altitude and azimuth of the body | Consent (Android permission, revocable at any time) | Stays on the device |
| Manually entered location, favourite and recent locations | Allow computation without GPS and remember your usual spots | Performance of the requested service | Stays on the device |
| Coordinates passed to the system geocoder | Show a town name instead of raw coordinates | Performance of the requested service | Android system geocoding service (Google on most devices) |
| City search text | Find an observation location | Performance of the requested service | Nominatim (OpenStreetMap Foundation) |
| IP address and map area viewed | Download map tiles | Performance of the requested service | OpenStreetMap tile servers |
| Advertising identifier and technical device data | Display the banner ad that funds the app | Consent (form shown on first launch) | Google and its advertising partners |
The app displays a banner served by Google AdMob. On first launch, in the European Economic Area, the United Kingdom and Switzerland, a TCF-compliant consent form is presented. No ad request is made before you answer.
You can change your choice at any time from Settings › Privacy › Manage my privacy options. Withdrawing consent takes effect immediately.
How Google processes data: policies.google.com/technologies/partner-sites. You can also reset or delete your advertising identifier in the Android settings (Settings › Privacy › Ads).
All app data — active location, saved locations, cache of computed eclipses, preferences — is stored only in the app's private storage on your device. It is permanently deleted when you uninstall the app or clear its data from the Android settings.
If Android automatic backup is enabled on your device, this data may be copied to your personal Google Drive space, to which the publisher has no access.
The General Data Protection Regulation grants you rights of access, rectification, erasure, restriction and objection, as well as the right to withdraw your consent.
In practice, since the publisher holds no data about you, these rights are exercised directly on the device: revoke the location permission in the Android settings, withdraw advertising consent from the Settings screen, clear the app data or uninstall the app. For any question, write to o.popiers@gmail.com.
You may lodge a complaint with your national data protection authority — in France, the CNIL.
EclipseGPS is not directed at children under 13 and does not knowingly collect their data.
This policy may change. The date of the last update appears at the top of the page; substantial changes will be noted in the app's release notes.
