1. Technically Necessary

The website and the apps store data on your device that is needed for the service you requested (Section 25(2) no. 2 TDDDG): sign-in state, language, audio and display settings, caches of packs and images, game progress that has not been sent yet, and an anonymous ID for web purchases.

To protect the website against abuse, Firebase App Check uses Google reCAPTCHA, which may set its own cookies and evaluates technical information about your browser. This is necessary to keep the service secure.

2. Advertising (Apps)

The free version of the apps shows ads from Google AdMob. Advertising identifiers and personalized ads are used only after your consent; on iOS also only after App Tracking Transparency permission. You can change your choice in the app under Profile → Privacy & legal → Ad privacy choices.

3. Advertising and Analytics (Website)

The website may show ads from Google AdSense. Google and its partners then use cookies and similar technologies to show and measure ads, to limit how often you see the same ad and to prevent fraud. In the EEA, the UK and Switzerland these are only used after you consent in Google's consent message, and you can change your choice at any time through the privacy settings link of that message. You can turn off personalized ads from Google in My Ad Center (https://myadcenter.google.com).

Star Club members see no ads. The website uses no analytics cookies.

4. Your Choices

You can delete stored data in your browser or by reinstalling the app. Deleting technically necessary data signs you out and resets local settings.
