Understanding Cookies
What is a cookie?
A cookie is information saved by your web browser, the software program you use to visit the web. When you visit a website, the site might store a cookie so it can recognize your device in the future. Later if you return to that site, it can read that cookie to remember you from your last visit. By keeping track of you over time, cookies can be used to customize your browsing experience, or to deliver ads targeted to you.
Who places cookies on the web?
First-party cookies are placed by the site that you visit. They can make your experience on the web more efficient. For example, they help sites remember:
•items in your shopping cart
•your log-in name
•your preferences, like always showing the weather in your home town
•your high game scores.
Third-party cookies are placed by someone other than the site you are on. For example, the website may partner with an advertising network to deliver some of the ads you see. Or they may partner with an analytics company to help understand how people use their site. These “third party” companies also may place cookies in your browser to monitor your behavior over time.
Over time, these companies may develop a detailed history of the types of sites you frequent, and they may use this information to deliver ads tailored to your interests. For example, if an advertising company notices that you read a lot of articles about running, it may show you ads about running shoes – even on an unrelated site you’re visiting for the first time.
