Appended and Matched Data

Yahoo! collects personal information as described in our Privacy Policy, such as when you register with Yahoo!, when you use Yahoo! products or services, when you visit Yahoo! pages or the pages of certain Yahoo! partners, and when you enter promotions or sweepstakes. Yahoo! may combine information that we have about you with information we obtain from business partners or other companies. The data provided by these partners and other third parties is used in combination with our existing data to offer users more relevant products and services.

Information Collection Practices

• We offer personalized content, products and services to users based on information we obtain through the registration process, your use of the Yahoo! network of sites, and information you share with us through interactions like surveys or sweepstakes.
• Yahoo! may from time to time obtain data from third parties such as business partners or other companies and append it to existing user data to add more detail to the information we have about you.
• Appended data may be aggregated and anonymous and may include information such as household income range or average household size.
• Appending user information with data obtained from third parties allows Yahoo! to offer users more relevant content and advertising.

Data Matched for Partners

• In some cases partners share data with Yahoo! for use in identifying and delivering ads to their customers. Yahoo! only uses this information on behalf of the partner, and may use a 3rd party vendor for client data matching to assist in this process.

Data Appended for Yahoo!’s Use

• Yahoo! may append data about users that are publicly available or aggregated by 3rd party data vendors. This data may be associated with personally identifiable information such as email address, name and physical address if we have it. In some cases data is aggregated based on zip code or zip+4 and appended to user records in the aggregate.
• Appended data may be used to provide customized content and advertising.

Your Ability to Opt Out of Ad Customization

• Yahoo! offers you the choice to opt out of ad customization. If you opt out data we collect, match or append will not be used for ad customization.
