Your learning record

Ankommen stores scores, answers, review schedules, notes, selected federal state and preferences on your device. No app account is required. The app does not send your learning record to an Ankommen server. The question bank is included in the app and can be studied offline.

Export creates a file that you choose where to save or share. Import replaces your learning record after confirmation. Reset removes your local progress. Removing the app also removes its local data, subject to your operating system's backup and restore settings.

Purchases

Apple handles payments. Ankommen does not receive your payment-card details. RevenueCat processes purchase history, receipts or transaction information, subscription status and an anonymous app-specific identifier to provide, validate and restore Premium access and understand subscription activity. Basic technical information, including platform, app and operating-system versions, country and locale, may accompany purchase requests. Ankommen does not associate the anonymous identifier with an account, name or email address.

Read RevenueCat's privacy policy and Apple's privacy policy. Purchase information may be retained as necessary to provide and restore access and meet legal recordkeeping obligations. Processing can involve service providers in other countries under their applicable data-transfer arrangements.

Reminders and speech

If you enable reminders, the app asks for notification permission and schedules a local daily reminder. You can change permission in your iPhone settings. German audio uses your device's speech service. The app does not request microphone access or record your voice.

Advertising and tracking

The free version uses Google AdMob. Its SDK and consent platform may process IP addresses and approximate location inferred from them, app- or device-related identifiers, ad views and interactions, consent choices, and crash/performance information to deliver and measure ads, prevent fraud and operate the service. Ankommen requests non-personalized ads only after the consent platform allows ad requests. Non-personalized ads can still involve personal information and device storage. Premium removes advertising. The app does not request tracking permission or access your device location services. Read Google's privacy policy for its retention and international data-transfer practices. Use Advertising privacy choices in Settings to revisit available consent options. Advertising stays off when consent checks do not permit an ad request.

Support and website visits

If you email support, we receive your email address and the information you include so that we can respond. Do not send citizenship documents or card details. The website hosting provider may process IP addresses and browser information to deliver and protect these pages. External links open services with their own privacy policies.

Your choices and requests

Local learning information can be exported or reset in Settings. Contact max@artificial-experiments.com for access, correction, deletion or other applicable privacy requests involving support or purchase information. We may need transaction information to locate an anonymous purchase record. Some records must be retained where required by law. You can raise a complaint with your relevant data protection authority.
