Some of the advertisements you see on the CBS Interactive Services are delivered by third parties who also collect information through their own cookies, web beacons, and other similar technologies about your online activities, either on our Services or across the Internet, in an effort to understand your interests and deliver advertisements that are tailored to your interests. These third parties include advertisers, advertising agencies, and ad networks that may collect information about you when you view or interact with one of their advertisements and may collect information about your online activities over time and across different websites.
Also, we work with DigiTrust to set a first-party cookie in your browser to enable us and DigiTrust Partners to collect web viewing data that includes visits to the Services and non-affiliated websites over time. This data may be used to infer whether you share interests with other users, and deliver advertising relevant to those inferences. DigiTrust is a non-profit, industry-wide collaboration of companies supporting a standardized user token in order to improve the consumer online experience. To learn more about how DigiTrust collects and uses information for online advertising, please visit http://www.digitru.st/privacy-policy/. You can opt-out of the collection of data in this way for interest-based advertising by visiting the DigiTrust opt-out page here or the Digital Advertising Alliance’s choice page and opting out from DigiTrust. Please note that limiting third-party cookies via your browser controls does not prevent a first-party cookie from being set in this way.
On certain mobile devices, third parties may collect mobile device identification numbers (e.g. Apple’s Identifier for Advertising IP (IDFA) or Google’s Android Advertising ID (AAID)) and may use this information in connection with other data about you (or that you have provided to parties other than us), including data regarding your use of websites, apps or other services over time to deliver advertisements tailored to your interests across these devices. You may be able to opt out of such tailored advertisements through settings made available by mobile operating systems. For example, Google Android settings may allow you to opt out of interest based advertising or Apple iOS settings may allow you to limit ad tracking.
