In apps that use Google Play Games Services, we obtain your player ID, display name, and avatar image URL when you sign in, and use them to identify you as a player and provide game services.

3. Advertising

Apps that display ads use AppLovin and Unity Ads through Adfurikun.

Advertising services may collect information such as the advertising ID (Android’s advertising identifier), IP address, device model, operating system, language settings, information about the app displaying the ad, and ad impressions and clicks. They may process this information on their servers to deliver ads, measure their effectiveness, prevent fraud, and for related purposes.

The advertising ID, ad impressions and clicks, and related information may also be used to select ads based on your interests (personalized ads). The information collected and used varies depending on the service, your device settings, and other factors.

You can change ad display settings within the app. You may need to restart the app for changes to take effect.

For details about each service’s use, sharing, retention, and deletion of data, advertising settings, and how to exercise your rights, please see the provider’s privacy policy.
