Appended & Matched Data

In order to deliver the most engaging and personalized experience for our users, we may collect information, including personal information as described in our Privacy Policy, when you register with us, use our products or services, visit our pages or the pages of certain partners, or enter promotions. We may combine this information with information we obtain from our partners and affiliates and use it to offer you more relevant content and advertising.

Information Collection & Use Practices

  • We may obtain information from our partners and append it to our existing user information to better understand users’ interests and to provide more relevant content and advertising. We may work with the following partners in this regard:

  • We may append information about you that is publicly available or information that is aggregated and/or depersonalized by partners. This information may include, for example, average household size, household income range, or postal code. This information may be associated with personal information as described in our Privacy Policy, such as email address, physical address, first and last name combined, or phone number.

Information Matched for Advertisers

  • In some cases our advertisers may share information, including personal information, with us in order to identify and deliver the most relevant ads to their customers. We use this information only on behalf of the advertiser who provided it and do not store this information beyond the campaign or use it independently of our advertiser’s instructions. We 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’s or Yahoo’s information for any independent purpose.

Your Interest-Based Advertising Controls

  • We offer controls built-in to personalize your experience or to enable you 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.
