Most advertisements you see on the Yahoo! network of web sites are served to your web browser by Yahoo!. However, we also allow other companies, called ad networks, to serve advertisements within our web pages. Yahoo! may allow certain Yahoo! partners to include web beacons within pages served by Yahoo!, and may also share portions of our log file data with these partners. These partners aggregate information about our advertising and provide auditing, research and reporting for us and our advertisers.
Yahoo! displays ads both on our network of owned and operated websites, such as the sites on the Yahoo.com domain and sites like Flickr.com others (see our Acquired Companies page for more) and on non-Yahoo! web sites. Yahoo! serves display ads, also known as graphical ads, that appear as images, animation or video as well as text ads that appear as text links.
In order to better serve our customers and to provide the foundation for product and service improvements, Yahoo! maintains data about registered users, user generated content, product specific data, and general user activity of our products and services. Data is stored both on production systems to support our products and services and on back-up storage systems for recovery purposes.
When your web browser or email application requests a web page or email from another computer on the Internet, it automatically gives that computer the address where it should send the information. This is called your computer's IP address. (IP stands for Internet protocol.) For most users accessing the Internet from a dial-up Internet service provider (ISP), the IP address will be different every time you log on.
A web beacon is typically an invisible image that may be embedded in a web page. Its primary purpose is to count the page's visitors. It also collects other information, such as IP address, the time the page was viewed, and the type of browser used by that computer. In general, any element of a web page, including an ad banner, can host a web beacon.
Yahoo! takes your security seriously and takes reasonable steps to protect your information. No data transmission over the Internet or information storage technology can be guaranteed to be 100% secure. The following is a summary of the measures Yahoo! takes to protect your information and descriptions of ways we implement these measures for different types of information you may provide to us.
A cookie is a small amount of data, which often includes an anonymous unique identifier, that is sent to your browser from a web site's computers and stored on your computer's hard drive. Each web site can send its own cookie to your browser if your browser's preferences allow it, but (to protect your privacy) your browser only permits a web site to access the cookies it has already sent to you, not the cookies sent to you by other sites.
Yahoo! offers a variety of location-aware products and services to provide you with more relevant content for where you are in the world. We obtain information about your location through various methods like pinpointed GPS data or when you submit a partial address to look at a map of an area.
Yahoo! delivers cutting edge mobile experiences to your handheld device. To customize our services for your device, we use IP address information, the type of device you are using, and, possibly, information about your mobile provider. If you opt in to sharing your location information with us, we offer location-based services that help you find things of interest in your area or let you use products like Fire Eagle. You can opt out of location sharing anytime.
