Limit targeted interest-based ads.
Our business does not depend on advertising. For many companies, it does. On iOS, advertising does support some apps, so to help protect your privacy we have developed the nonpersistent Advertising Identifier. Apple’s advertising service, iAd, uses this identifier to deliver ads to you via things like third-party apps and iTunes Radio. The Advertising Identifier helps advertisers control the number of times you see a given ad and measure the effectiveness of ad campaigns, and — unless you choose to opt out — can be used to try and serve ads more relevant to you.
Whenever you want to clear the data associated with your Advertising Identifier, you can simply reset it. This is another example of our commitment to do away with persistent identifiers on mobile devices. If you’d rather not see mobile ads tailored to your interests, you can choose to limit ad tracking with a simple on/off switch. When Limit Ad Tracking is turned on, third-party apps are forbidden by Apple’s guidelines to use the Advertising Identifier to serve you targeted ads. As part of submission to our App Store, Apple requires all developers to agree that they abide by your choice to limit ad tracking. iAd abides by Limit Ad Tracking wherever ads are served, and does not serve interest-based ads to users under the age of 13.
