Advertising funds our Services and enables us to make our Games available free of charge. In our Games, we show our own ads and also ads from third parties. We also advertise outside of our Services on third-party properties such as websites or applications. This section provides more information on how we may use your data for advertising purposes, and how you can control the use of your data for these purposes.
Mobile advertising relies on the use of certain online identifiers, in particular Advertising IDs but also IP addresses or other identifiers. An “Advertising ID” is an alphanumeric string of digits provided by the operating system of a device. It is consistent across applications from different publishers. The Advertising ID is known as the Identifier for Advertisers (“IDFA”) on iOS devices and Google Advertising Identifier (“GAID”) on Android devices.
Advertising IDs are used for interest-based advertising and other advertising related purposes. You can control the extent to which your Advertising ID is used for these purposes. Using the privacy settings on your device, you can typically reset and/or limit the use of your Advertising ID. For example, you can “limit ad tracking” on iOS devices or “opt out of interest-based ads” on Android devices. These settings are specific to each device, which means that you should set them to your desired state on each of your devices individually. It may take some time for your updated settings to take effect. Please consider that resetting or limiting the use of your Advertising ID will not stop you from seeing ads, but the ads you see may be less relevant to you.
When you see ads in our Games, we may share your Advertising ID and IP address with our advertising partners. Our advertising partners may also collect information directly from our Games through technologies such as software development kits (SDKs). In each case, they may use your data for a number of purposes, including to limit the number of times you see an ad or to personalize the ads you see to make them more relevant to you (for example, based on the past activity they have associated with your Advertising ID).
