App Privacy Policy

Last updated: 14 June 2026

Umbra helps you find good places to watch the 12 August 2026 total solar eclipse. This policy explains what the mobile app does and does not do with your data.

The short version

No account, no sign-up, no profile. We don't ask who you are.
We run no server that stores your data, and we don't sell or share data for advertising. The app has no ads and no third-party tracking SDKs.
The app talks to a few third-party services to do its job (maps, weather, search, purchases). Each receives only the minimum needed for that request.

Location (optional)

If you tap “Use my current location”, the app reads your device location to rank viewing spots near you — used on your device. You can instead pick a city, enter coordinates, tap the map, or search a town, none of which use device location. The app requests location only when you choose that option.

Network requests to third parties

To function, the app contacts these services. They may receive your IP address (unavoidable for any internet request) plus the data noted:

OpenStreetMap / OpenTopoMap (map & terrain tiles) — the tiles being viewed.
Open-Meteo (clear-sky forecast, the week before the eclipse) — the coordinates of the spot being checked.
OpenStreetMap Nominatim (town search) — the text you type.
Google Play Billing / RevenueCat (in-app purchases, if you buy a tier) — purchase receipts and a store-provided identifier.

We don't attach your identity to any of these requests.

Purchases

Paid tiers are processed by the app store (Google Play / Apple) and managed via RevenueCat, which provides an anonymous identifier so the app knows which tier you own. We never see your card details.

Analytics

The mobile app contains no analytics or tracking. Our website (eclipse.lluisgasso.com) uses Google Analytics to count visits; that is covered by the website's own notice and is separate from the app.

Data we store

On your device only: your selected location, chosen filters, and which tier you own — removed when you uninstall. On our servers: nothing.

Children

Umbra is a general-audience utility, not directed at children, and we do not knowingly collect personal information from children.

Your choices

Deny or revoke the location permission in your device settings — the app still works fully via manual location entry and search. Uninstalling removes all locally stored preferences.
