Privacy Policy

1. Who is responsible and what this policy covers

This policy covers the Wortgarten German vocabulary application for Android and iOS, including its purchase-enabled releases. It replaces the earlier policy wording that described purchases as disabled.

The controller responsible for the app’s processing of personal data is:

Our other websites and applications may have different privacy practices. When you visit the website hosting this policy or follow an external link, that website’s own privacy and cookie information also applies.

2. Data stored on your device

Wortgarten stores learning information locally so that you can practise and continue where you left off. This includes:

• Practice answers and results, vocabulary progress and review schedules.
• Bookmarks, favourites and custom word lists, where available.
• Daily goals, study streaks and activity history.
• Onboarding status, audio settings and other preferences.
• Reminder preferences and locally scheduled notifications.

We do not upload this learning information to our servers or to RevenueCat. No app account, email address or password is required for learning. Purchase status and RevenueCat’s customer identifier are separate from your local learning records.

Your operating system may include app data in device or cloud backups, depending on your settings. Apple or Google controls the processing associated with those backups under its own policies.

3. Premium purchases and RevenueCat

Store payments

Wortgarten offers weekly and monthly Premium subscriptions and a lifetime purchase. When you purchase, the Apple App Store or Google Play processes the payment through your store account. We do not receive your payment-card number or bank-account details.

Purchase verification and access

We use RevenueCat, Inc. to verify store transactions, determine Premium access, restore purchases, handle changes such as renewals and refunds, and view subscription performance. RevenueCat processes purchase records on our behalf for these services.

Information involved in this processing can include:

• A randomly generated RevenueCat customer identifier and identifiers associated with restoring or transferring purchase access.
• Purchased product, store and transaction identifiers; receipt or purchase-token information; purchase dates; and subscription, renewal, expiration or refund status.
• Relevant app, SDK, operating-system and device-type information, store country or locale, currency and transaction amounts when provided by the store.
• Service activity timestamps, such as when purchase status was last checked. Network requests also expose connection information, such as an IP address, to the services receiving them.

The app does not set a custom customer ID tied to your name or email, send contact attributes to RevenueCat, or enable automatic device-identifier collection. We do not send RevenueCat your vocabulary progress, practice answers, favourites or custom word lists.

RevenueCat calls its randomly generated identifier an “anonymous App User ID.” This is a pseudonymous identifier: it helps distinguish a purchase record without an app login, but does not mean every associated transaction record is irreversibly anonymous. A support request or store transaction you provide may allow us to locate the relevant record.

Subscription analytics

We use purchase information to understand Premium subscription performance, such as purchases, renewals and cancellations. This is separate from tracking your study behaviour. On iOS releases with Apple Ads attribution enabled, we use Apple AdServices with RevenueCat to measure Apple Ads acquisition and the purchases associated with it. This does not use IDFA or request the App Tracking Transparency permission.

Restoration and cancellation

Restoring purchases checks your store transactions and RevenueCat access record. It restores eligible Premium access; it does not provide cloud synchronisation of local vocabulary progress. A purchase or restore requires a network connection.

Manage or cancel subscriptions through your Apple or Google store account. Deleting Wortgarten or requesting deletion of purchase data does not cancel a store subscription. Store refund rules apply separately.

Further information: RevenueCat privacy policy and RevenueCat data processing information.

4. Support, audio, reminders and external services

Support requests

If you contact us, we process your email address, message and information you choose to provide. For purchase support, this may include a transaction reference or purchase record needed to identify the issue. Please do not send payment-card details, store passwords or unnecessary sensitive information.

Vocabulary and audio

Vocabulary and complete A1 illustrations and audio are included in the app. A2–C1 practice requires a one-time level-pack download from our media-storage provider, Tigris. Downloaded packs then work offline. Download requests expose technical information such as your IP address, requested files and request times to the hosting provider; they do not include your learning progress or RevenueCat customer identifier. If a recording is unavailable, Wortgarten may use your device’s text-to-speech service. Voice downloads and any network processing depend on your selected speech provider and device settings, and are governed by that provider’s policy.

Study reminders

Optional reminders are scheduled locally. The app may request notification permission and read the device time zone to schedule them correctly. Reminders do not use a remote push-notification service. You can disable reminders in the app or revoke notification permission in device settings.

Advertising and other tracking

The app does not display advertising. On iOS, the app asks Apple AdServices for a standard attribution token and sends it to RevenueCat. RevenueCat uses the token to request attribution from Apple and associate available campaign, ad-group and keyword information with the app’s pseudonymous purchase record. This lets us compare acquisition and subscription performance. Organic or test installs may not have paid-campaign information. We do not collect IDFA, fingerprint your device or request ATT permission for this standard integration. It does not use Firebase Analytics, Firebase Crashlytics, Firebase Cloud Messaging or AdMob. We do not sell your personal data or share it for cross-context behavioural advertising. The purchase-related processing described above is still performed when the app communicates with RevenueCat and the stores.

Wortgarten does not request access to your contacts, precise location, camera, photographs or microphone for its vocabulary features. Device and store providers may separately process installation, diagnostic and other platform information under their own settings and privacy policies.

External websites opened from the app operate independently. Their cookies, analytics and privacy practices are outside the scope of this mobile-app policy.

5. Purposes and legal bases

Where the General Data Protection Regulation (GDPR) applies, our processing is based on the following, as appropriate to the activity:

• Providing requested services and Premium access: performance of a contract or steps requested before entering a contract (Article 6(1)(b)), including purchase verification, restoration and purchase support.
• Service security, fraud prevention, subscription-performance analysis and measurement of our Apple Ads campaigns: our legitimate interests in operating a secure service and understanding its paid features (Article 6(1)(f)), taking account of your interests and rights.
• Support inquiries: contract-related processing where relevant, or our legitimate interest in responding to questions and resolving problems (Article 6(1)(b) or (f)).
• Required legal records and lawful requests: compliance with applicable legal obligations (Article 6(1)(c)).
• Processing that legally requires consent: your consent (Article 6(1)(a)), which you may withdraw for future processing. A device permission alone is not treated as a blanket consent to unrelated processing.

Providing purchase information is necessary to verify and restore Premium access. Without it, we may be unable to provide those features. We do not use your data for decisions based solely on automated processing that produce legal or similarly significant effects.

6. Recipients and international processing

Recipients may include RevenueCat and its service providers for purchase management, Apple or Google for store transactions and platform services, Tigris for requested media downloads, and providers used to receive and answer support messages. Apple and RevenueCat also process the iOS advertising attribution described in section 4. We may also disclose information where legally required or necessary to establish, exercise or defend legal claims.

RevenueCat is based in the United States and uses service providers in multiple locations. Purchase and support information may therefore be processed outside your country, including outside the European Economic Area. Applicable safeguards for restricted transfers can include an adequacy decision or the European Commission’s Standard Contractual Clauses. RevenueCat describes its processing terms and transfer mechanisms in its published data processing addendum. You can contact us for information about safeguards relevant to your data.

7. Retention and deletion

Local learning data: remains on your device until you clear the app’s storage or delete the app. On iOS, offloading may retain app data. Existing device or cloud backups are controlled separately; restoring a backup may restore previously saved learning data.

Advertising attribution: Where available, campaign attribution remains associated with the pseudonymous RevenueCat customer record to measure subsequent purchases and renewals. It is subject to the same support/deletion request process described here.

Purchase information: is retained as necessary to verify access, support restoration, manage subscriptions, prevent fraud, resolve disputes and meet applicable legal requirements. The relevant period depends on the purchase and the continuing purpose; lifetime access may require a continuing entitlement record. We do not promise that uninstalling the app immediately erases store or RevenueCat records.

Support messages: are retained while needed to handle the inquiry, follow-up or dispute and to meet applicable legal obligations, then deleted or de-identified when no longer needed. Backups and security records may be removed according to the relevant provider’s retention cycles.

To request deletion of purchase or support information that we control, email support@deutsch-pruefung.de. We may need limited purchase information to locate the pseudonymous record and verify your request. We do not need your store password or full payment-card details. We will explain any information that must be retained and why.

Deleting a purchase-management record may affect entitlement recognition until eligible purchases are restored. A later store transaction or restore can create a new access record. Requests about Apple’s or Google’s independent records must be addressed to that provider.

8. Your rights and choices

Depending on your location and applicable law, you may have rights to access, correct, delete or restrict processing of your personal data, receive a portable copy, and object to processing based on legitimate interests. Where processing relies on consent, you can withdraw it without affecting processing that was lawful before withdrawal.

Contact us using the email below to exercise your rights. We may need to verify your identity and locate the relevant records. We do not require you to create an app account to make a request. Your local learning data is not accessible to us, so you control its deletion on your device.

You may complain to a data-protection supervisory authority, including the authority where you live or work or where you believe an infringement occurred. In Berlin, you can contact the Berlin Commissioner for Data Protection and Freedom of Information.

You can also manage notification permissions, backup settings and store subscriptions through your device or store account. Purchasing Premium does not require consent to advertising tracking.

9. Security

We use reasonable technical and organisational measures appropriate to the processing. App data is stored within your device’s application-storage controls, and purchase-service communications use encrypted connections. Protect your device with a screen lock and keep its operating system updated. No storage or transmission method can guarantee absolute security.

10. Children and young people

Wortgarten is intended for people aged 16 and older. It is not directed to children under 16. We do not knowingly seek personal data from children under 16. If you believe such information has been provided to us, contact us so that we can investigate and take appropriate action.

A store’s content rating describes the app’s content and does not replace this intended-audience statement or the store’s requirements for purchases and parental authorisation.

11. Changes to this policy

We may update this policy when the app, service providers or privacy practices change. The effective date identifies the version. We will provide additional notice or obtain consent where required before introducing materially different processing.

12. Contact

For privacy questions, access requests or purchase-data deletion requests, contact Amrendu Kumar — Deutsch Prüfung at support@deutsch-pruefung.de. Please mention Wortgarten so that your request reaches the right service.
