Coffee Voyage
Privacy Policy
Last updated: August 13, 2026
01Principle
Coffee Voyage is a local application. There is no user account, no registration and no server operated by the Service Provider. Everything you enter is stored solely in a database on your device and is never transmitted to the Service Provider. At no point does the Service Provider have access to your entries.
02What the App Stores
On your device the app stores what you record: the coffee you drank, the time, your rating, the taste notes you selected and, optionally, a note, a price and a photo. For cafés it stores the name and, optionally, city, country, address and coordinates. This data never leaves your device.
03Location Information
The app requests location permission only at the moment you explicitly tap “Save current location” while creating a café. The coordinates are stored locally with that café. To derive the city and country from them, the coordinates are passed to your operating system's geocoding service (Apple or Google). No background location tracking takes place. The app is fully usable without location access; cafés can also be created without coordinates.
04Photos and Camera
When you attach an image to an entry, the app requests access to the camera or the photo library. The selected image is copied into the app's protected storage; the database holds only a reference to it. Nothing is uploaded, and the app does not read your photo library beyond the image you pick.
05Map Display
The map section loads map material from Apple Maps (iOS) or Google Maps (Android). This transmits technically necessary data such as your IP address and the requested map area to the respective provider. The privacy policies of Apple (apple.com/legal/privacy) and Google (policies.google.com/privacy) apply. Your coffee entries are not transmitted in the process.
06Purchases and Subscriptions
The app uses RevenueCat to handle its premium features. This involves a pseudonymous, randomly generated user identifier along with purchase status and device information, so that unlocked features can be restored across devices. The purchase itself is processed by the App Store or Google Play; neither the Service Provider nor RevenueCat receives your payment details. Privacy policy: revenuecat.com/privacy.
07Analytics and Tracking
The app contains no analytics tools, no advertising tracking, no cookies and no advertising identifier. No profiling takes place, and no usage data is transmitted to the Service Provider.
08Artificial Intelligence
The app does not use artificial intelligence technologies. The taste profile is a purely descriptive summary of your own entries and is computed entirely on your device.
09Third-Party Services
The app relies on the following services, each with its own privacy policy: RevenueCat for purchases (revenuecat.com/privacy), Expo as the development platform (expo.dev/privacy), Apple Maps (apple.com/legal/privacy) and Google Maps together with Google Play Services (policies.google.com/privacy) for maps, location resolution and purchase handling on Android.
10Disclosure of Information
Since the Service Provider never receives your entries, they cannot be disclosed. Information is disclosed only where the Service Provider is legally obliged to do so, for instance in response to a court or authority order.
11Data Retention and Deletion
Your data stays on the device until you delete individual entries in the app or uninstall it. Uninstalling removes all entries and photos irrevocably. As no copy exists on any server, the Service Provider cannot restore them.
12Children's Privacy
The app is not directed at anyone under the age of 13. The Service Provider does not knowingly collect data from children. Because the app works without an account and transmits no data, no children's data reaches the Service Provider either.
13Security
Your entries live in the app's protected storage area, which other applications cannot access under the rules of the operating system. Enabling device encryption and a screen lock is recommended, as the protection of your data depends substantially on the security of your device.
14Your Rights
You have full access to your data at all times, since it resides solely on your device where it can be viewed, changed and deleted. Rights to information, correction and deletion against the Service Provider are largely moot, as it stores no personal data about you. For data arising from a purchase at RevenueCat, Apple or Google, please contact the respective provider or the Service Provider, who will gladly assist.
15Changes to This Privacy Policy
This Privacy Policy may be updated from time to time. The Service Provider will notify you of changes by updating this page with the new version. You are advised to review this page regularly, as continued use is deemed approval of the changes.
16Contact
If you have any questions regarding privacy while using the app, please contact the Service Provider by email at martin-hoffmann-e-mail@web.de.
