Some websites you visit and some apps you download from the Store may display advertisements using Microsoft's advertising platform, including personalised ads that we believe may be of interest to you. Microsoft Advertising may also use third-party ad companies to display advertisements in applications that use our ad platform. When we do so, we may send a unique ID to those third parties with the ad request. You may opt out of receiving personalised ads from Microsoft Advertising, and discontinue sending a unique ID to third-party ad networks used by Microsoft Advertising, by visiting our opt-out page. Just sign in with the Microsoft account that you have associated with your Windows Phone and that you use to access the Store, and select the Personalised ads wherever I use my Microsoft account opt-out option. For more information about how Microsoft Advertising collects and uses information, please see the Microsoft Advertising Privacy Statement.
