Appended and Matched Data
Information Collection Practices
- Yahoo may obtain information from our trusted partners and append it to our existing information to add more detail to the information we have about our users. We may use appended information to provide more relevant content and advertising. Yahoo may obtain information from, or work with, the following trusted partners to provide more relevant content and advertising:
- Yahoo may append information about you that is publicly available or information that is aggregated and/or anonymized by trusted partners. This information may include, for example, average household size or postal code. Yahoo may also append other demographic information about you such as household income range and general location. This information may be associated with personally identifiable information such as email address, name and physical address.
Information Matched for Advertisers
- In some cases our advertisers may share information (including personally identifying information) with Yahoo for use in identifying and delivering ads to their customers. Yahoo uses this information only on behalf of the advertiser who provided it. Yahoo may match this information to our existing user information or may use a third party vendor to assist in this process. The third party vendor may not use the advertiser or Yahoo information for any independent purpose.
Your Ability to Opt Out of Interest-based Advertising
- Yahoo offers you the choice to opt out of receiving interest-based content and advertising. If you opt out, your information will not be appended to or matched with third parties' information about you for the purposes described above, and you will no longer receive interest-based content or advertising. Additionally, if you opt out, information about your visits to our advertising partner websites will not be used to provide reporting to partners using Yahoo’s analytics product.
