Privacy Policy

1. Who this policy covers

This policy covers GeoStamp (the Android application, package name com.geostamp.app) and the public website at which this policy is published. GeoStamp is provided by the maintainers of the GeoStamp project.

The app does not have GeoStamp accounts, a GeoStamp photo-hosting service, or a GeoStamp analytics backend.

2. Information and permissions used by the app

Camera and photos. Camera access is used to take pictures. GeoStamp processes a captured image on your device to create the photo and any stamp you select. The app does not send the photo itself to GeoStamp servers.

Location. When location stamping is in use and permission is granted, the app uses the device's location to make a stamp. A stamp can include coordinates, address information, a map and the capture time. Android location permission can be denied or changed in device settings.

App preferences. The app saves settings such as stamp style, photo quality and date/time preferences on your device. It also stores small local app-state values, such as whether an in-app review prompt was already shown.

Advertising and diagnostics. The app uses the Google Mobile Ads SDK to request and display banner ads on Android. Google and its advertising partners may process information such as device or advertising identifiers, IP address, ad interactions, and diagnostics to provide, measure and protect advertising services. The exact information and purposes can depend on your device, settings, consent choices and Google's services. See Google's Privacy Policy and Google ad controls.

3. Location, address lookup and maps

Location stamping is optional and can be turned off in GeoStamp Settings. When location features are used, GeoStamp sends the relevant latitude and longitude to external services for reverse geocoding (turning coordinates into an address) and map tiles. The app currently uses Photon, may use Nominatim as an address fallback, and retrieves map tiles from OpenStreetMap.

These requests disclose the coordinates needed for the requested feature and can also disclose ordinary network information, such as your IP address and the app's network request metadata, to the provider. GeoStamp does not send your photo to these providers for address lookup or map tiles. Those services process requests under their own privacy policies and terms:

• Komoot privacy policy (Photon)
• OpenStreetMap Foundation privacy policy
• OpenStreetMap tile usage policy

4. Photos, saving and sharing

Captured photos and generated stamped images are stored locally in GeoStamp's app storage and, when saved, in the device photo gallery or a folder you choose. GeoStamp may also read a photo you select for preview or sharing. You can review or delete photos in the app and manage exported copies using your device's tools.

When you choose to share or export a photo or PDF, Android's system share interface passes it to the app or destination you select. That recipient's handling of the file is governed by its own terms and privacy practices. GeoStamp does not control copies saved by recipients.

Uninstalling GeoStamp removes app-private files and settings managed by Android. Photos already saved to a shared gallery, another folder, or another app may remain and must be removed separately.

5. Advertising

The Android app displays banner advertisements supplied by Google Mobile Ads. Google may collect or receive information from the app and device to deliver ads, limit fraud, measure performance, and, where permitted by applicable settings and requirements, personalize ads. GeoStamp does not operate the advertising network or determine Google's independent retention practices.

You can review or change available ad-personalization settings through your Google account and Android device settings. You can also learn more in Google's advertising information.

6. Storage and retention

GeoStamp has no account database or GeoStamp server holding your photos or location history. Photos and preferences remain on your device until you delete them, clear app storage, or uninstall the app. A photo exported to a gallery, folder, share target or other app may persist separately.

When you request an address or map, the relevant service provider receives a network request. The provider may retain request data under its own policy. Google advertising services may retain and use advertising data as described in Google's policies.

7. Third-party services

GeoStamp relies on third-party services for advertising (Google Mobile Ads), reverse geocoding (Photon and, when needed, Nominatim), map tiles (OpenStreetMap), Android photo sharing, and Google Play in-app updates. A request to those services is subject to the applicable provider's privacy policy and terms. GeoStamp does not control how independent providers process information they receive.

8. Security and your choices

Keeping photos and preferences on your device avoids sending them to a GeoStamp photo server, but device storage and sharing still depend on your Android device, its security settings, and the services you choose. Use a device lock, keep Android up to date, and take care before sharing photos that reveal a location.

• Deny or revoke camera and location permissions in Android settings.
• Turn off location stamping in GeoStamp Settings to create new captures without location details.
• Review, save or delete photos in GeoStamp and your device gallery.
• Use Google and Android settings to manage available ad and privacy choices.
