Privacy Policy

We take the protection of personal data seriously. Below, we explain which data may be processed in connection with the website and the app Stackd – Block Puzzle Game and for which purposes this may happen.

What this covers

This policy applies to the use of our website, the app, optional advertising, optional in-app purchases, and technical services related to Stackd.

Key point

The app can generally be used without registration. However, certain technical services, advertising, or store-related processes may require the processing of limited data.

1. Data Controller

The controller responsible for data processing is the entity listed in the Imprint (hereinafter referred to as “we”, “us”, or “our”).

2. Use of the App

The app can generally be used without registration and without creating a user account. Game progress, settings, and scores are – where technically предусмотрено – primarily stored locally on the device.

Where required for technical functionality, additional app-related information may be processed to ensure stability, delivery, and proper operation of the app.

3. Advertising in the App (Google AdMob)

The app may display advertisements via Google AdMob. For the delivery, measurement, and technical provision of advertising, Google and, where applicable, affiliated companies or partners may process technical information, including:

  • IP address, where technically required
  • Device information, such as device type, operating system version, and language
  • Advertising identifiers or device identifiers, where available and enabled on the device
  • Information about interactions with ads, such as impressions, clicks, or usage events

The integration of advertising helps finance the free app and may be based on Art. 6(1)(f) GDPR where a legitimate interest exists. Where consent is required, for example for personalized advertising or tracking, processing is based on Art. 6(1)(a) GDPR following the relevant consent.

Provider: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland.

More information is available at https://policies.google.com/technologies/ads.

4. In-App Purchases

The app may offer optional in-app purchases, for example for coins, unlocks, or other additional content. Payment processing is handled by the relevant platform providers, in particular Apple or Google.

We generally do not receive full payment details such as credit card numbers. Instead, we only receive the information necessary for the technical provision, verification, and assignment of a purchase, such as product identifiers, purchase status, transaction data, or a technical user or device reference.

Processing may take place to provide the requested in-app functionality under Art. 6(1)(b) GDPR and for the technically secure and abuse-resistant provision of services under Art. 6(1)(f) GDPR, where a legitimate interest exists.

5. Technical Backend Service

We use a technical backend service, in particular Supabase, to support certain app functions. In this context, technical information may be processed where necessary for operation, stability, synchronization, verification, or security.

This may include anonymous identifiers, device-related information, technical event data, or information about feature usage, where required for the relevant purpose.

Provider: Supabase Inc., USA.

6. App Permissions

The app generally does not require access to contacts, photos, or location unless such access is explicitly shown in the app and approved by you.

7. Website Hosting and Server Log Files

When visiting this website, the hosting provider may process technically necessary data in server log files, such as IP address, date and time of access, accessed page, or information about the browser or device used.

This is done to ensure the availability, stability, and security of the website on the basis of Art. 6(1)(f) GDPR. Log data is regularly deleted unless longer retention is exceptionally required.

8. Recipients and Transfers to Third Countries

By integrating external services, in particular Google or Supabase, the processing of personal data outside the European Union or the European Economic Area cannot be excluded.

Where required, the respective providers rely on appropriate safeguards for such transfers, for example Standard Contractual Clauses.

9. Retention Period

We process personal data only for as long as necessary for the purposes stated above or as required by legal retention obligations. Technical log and system data is usually stored only temporarily and then deleted or anonymized.

10. Your Rights

Subject to the applicable legal requirements, you may have the right to access, rectify, erase, restrict processing, request data portability, and object to certain forms of processing.

Where processing is based on your consent, you may withdraw that consent at any time with effect for the future.

11. Contact

If you have any questions regarding privacy, you can contact us at info@taphighscore.de.

12. Changes to this Privacy Policy

We may update this Privacy Policy where necessary to reflect legal, technical, or content-related changes to our website or app.
