What’s a cookie?
- A “cookie” is a piece of information that is stored on your computer’s hard drive and that is sent by a web server to a web browser and is stored by the browser. It records how you move your way around a website so that, when you revisit that website, it can present tailored options based on the information stored about your last visit. A cookie contains an identifier (a string of letters and numbers) that is sent by a web server to a web browser and is stored by the browser. The identifier is then sent back to the server each time the browser requests a page from the server.
- Cookies do not typically contain any information that personally identifies a user, but personal information that we store about you may be linked to the information stored in and obtained from cookies. Cookies can also be used to analyze traffic and for advertising and marketing purposes.
