2. Scope
This statement applies to the lœrn mobile app and to public app-store pages that reference it.
3. Privacy at a Glance
lœrn requires no online account. Learning data stays on your device; advertising, store purchases and update checks may use the internet. There is no separate learning analytics or crash-reporting service.
4. Data Stored on Your Device
Decks, cards, local profile names, study progress, review history, settings and Premium status are stored locally. Optional reminders are scheduled on the device. You choose files to import, export or share; receiving services apply their own privacy policies. We operate no server for learning data.
5. Third-Party Processing
Google AdMob
Where ads are enabled, the app uses Google AdMob and requests non-personalized ads. Google may process information such as IP address, device and app information, advertising or other device identifiers where available and permitted, ad interactions, and diagnostics. The exact processing depends on your device, platform, region, consent choices, and Google's services.
Apple App Store / Google Play
Purchases and restores are handled by Apple or Google. They process transaction and store-account information under their own policies. We do not receive your payment-card details.
6. Purposes and Legal Bases
Where GDPR, UK GDPR, or similar law applies, processing may be based on performance of a contract (providing requested app and purchase functionality), legitimate interests (security, fraud/abuse prevention, and reliable operation), consent where required for advertising-related processing, and legal obligations.
7. Sharing
We do not sell personal information. Data may be processed by Apple, Google, and Google AdMob where the corresponding feature is used, or disclosed where required by law.
8. Advertising
The free/ad-supported version may display ads through Google AdMob. Requests from lœrn are configured as non-personalized. “Non-personalized” does not mean that no data is processed: technical data may still be used by Google to deliver and measure ads, prevent fraud, and meet legal requirements.
Premium is a one-time purchase that permanently removes ads, without a subscription. Ad loading and display are disabled for Premium users. The current app still initializes the advertising SDK at startup, including with Premium. Update checks may contact Apple or Google store services and transmit connection data such as your IP address, including with Premium.
9. In-App Purchases
Purchases are handled through Apple App Store or Google Play. lœrn stores only the limited state needed to recognize or restore premium access. Billing details are not available to us.
10. Retention and Deletion
Local app data remains on your device until it is reset or removed, for example by using available reset functions, clearing app data, or uninstalling the app. Device or cloud backups controlled by your operating system may retain or restore app data according to your backup settings. Third-party providers retain data according to their own policies.
11. International Transfers
Apple and Google may process data outside your country. Any international transfers are governed by the safeguards and terms of the relevant provider.
12. Security
We use reasonable technical and organizational measures appropriate to the app. No storage or transmission method can be guaranteed to be completely secure. Because core data is local, the security of your device and backups is also relevant.
13. Children
lœrn is intended for university students and older learners. Advertising requests are non-personalized and use the under-age-of-consent setting. Technical data may still be processed as described above. Parents can contact us about children's data.
14. Your Rights
Depending on your location, you may have rights of access, rectification, erasure, restriction, objection, portability, withdrawal of consent, and complaint to a supervisory authority.
Data deletion and user rights
We can delete only data we hold, such as your support emails, subject to applicable retention requirements. We have no direct access to AdMob data stored by Google and cannot delete it ourselves. Direct deletion requests for that data to Google using the linked privacy contact options. Our statutory data protection duties remain unaffected.
Clear app data on Android or delete the app with its data on iOS. Manage backups and exports separately. On supported Android devices, reset or delete the advertising ID in Privacy / Ads settings; names vary.
Google My Activity does not cover all AdMob data. Neither My Activity nor deleting the advertising ID erases all provider records. You may also exercise rights against us by email, including for support messages, even without our own user database. We cannot erase local data remotely. Google's privacy contacts for independent processing supplement, not replace, your rights against us. info@jetztunddahanna.com

16. Changes
We may update this statement when the app, providers, or legal requirements change. The current version will remain published at this URL so existing app versions continue to reach it.
