Privacy Policy

The controller within the meaning of Art. 4(7) GDPR is:

Further details are available in the Impressum (German only).

This website displays advertisements via Google AdSense. The provider is Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. Within the European Union, data processing is the responsibility of Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland).

Google AdSense uses cookies and similar tracking technologies to personalise ads and measure campaign effectiveness. Google may collect and process, among other things:

• Device and browser information
• IP address
• Cookie IDs and advertising IDs
• Pages visited and interactions (for interest-based advertising)
• Approximate location (based on IP address)

Data may be transferred to servers in the USA. Google is certified under the EU–US Data Privacy Framework, ensuring an adequate level of data protection for transfers to the USA (EU Commission implementing decision of 10 July 2023).

Personalised ads are only shown if you have given your consent. Without consent, AdSense displays only contextual, non-personalised ads.

This website uses Google Consent Mode v2. Consent signals (ad_storage, analytics_storage) are transmitted to Google before AdSense loads. Without consent, ad_storage is set to denied, preventing AdSense from setting personalising cookies. Further information: Google Consent Mode.

You can manage personalised ads via Google Ad Settings or opt out via the Digital Advertising Alliance opt-out tool. Further information on Google's data processing can be found in the Google Privacy Policy.

To provide an uninterrupted gaming experience, this website saves your game state (current puzzle, difficulty level, timer, moves) locally in your browser via IndexedDB.

This data is stored exclusively on your device and is not transmitted to us or any third party. It does not constitute personal data within the meaning of the GDPR, as no link to a specific individual is established.

You can delete locally stored data at any time via your browser settings (clear site data / cookies).

Under the GDPR you have the following rights: access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability where applicable (Art. 20), and the right to withdraw a given consent at any time with effect for the future (Art. 7(3)). To exercise these rights, please contact the address given in the Impressum (German only).

You also have the right to lodge a complaint with the competent data protection supervisory authority (Art. 77 GDPR): Landesbeauftragte für Datenschutz Brandenburg.

Where your data is processed on the basis of Art. 6(1)(f) GDPR (legitimate interests) — on this website this applies to Cloudflare server log files — you have the right to object at any time.

Following an objection, we will no longer process the data in question unless we can demonstrate compelling legitimate grounds that override your interests.

Please direct any objection to the contact address given in the Impressum.
