Web Beacons

Web pages may contain an electronic file called a web beacon, that allows a web site to count users who have visited that page or to access certain cookies. Yahoo! uses web beacons in the following ways:

Within the Yahoo! Network

Yahoo! uses web beacons within the Yahoo! network of web sites in order to count users and to recognize users by accessing Yahoo! cookies.
Being able to access Yahoo! cookies allows us to personalize your experience when you visit Yahoo! web sites that are located both on and off of the yahoo.com domain.

Outside the Yahoo! Network

Yahoo! uses web beacons to conduct research on behalf of certain partners on their web sites and also for auditing purposes.
Information recorded through these web beacons is used to report anonymous individual and/or aggregate information about Yahoo! users to our partners. Aggregate information may include demographic and usage information. No personally identifiable information about you is shared with partners from this research.
When conducting research that collects personal information Yahoo!'s practice is to require partners to disclose the presence of web beacons in their privacy policies and state what choices are available to users regarding the collection and use of this information. You may choose to opt-out of Yahoo! using this information.

Note: This opt-out applies to a specific browser rather than a specific user. Therefore you will have to opt-out separately from each computer or browser that you use.

HTML Mail

Yahoo!'s practice is to include web beacons in HTML-formatted email messages (messages that include graphics) that Yahoo!, or its agents, sends in order to determine which email messages were opened and to note whether a message was acted upon.

In general, any file served as part of a web page, including an ad banner, can act as a web beacon. Yahoo! may also include web beacons from third parties and affiliates within pages served by Yahoo! so that Yahoo!'s advertisers may receive auditing, research and reporting.
