Cookies are files which contain an identifier (a string of letters and numbers) that are sent by a web server to a web browser and are stored by the browser. The identifier is then sent back to the server each time the browser requests a page from the server.
Cookies may be either ‘persistent’ cookies or ‘session’ cookies. A persistent cookie will be stored by a web browser and will remain valid until its set expiry date, unless deleted by the user before the expiry date. A session cookie will expire at the end of the user session, when the web browser is closed.
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.
