Appended and Matched Data
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. These partners may include:
- We may append information about you that is publicly or commercially 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 other information we maintain about you, including your email address, physical address, full name, 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 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 Yahoo’s information for any independent purpose.
