What are cookies?
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, on the other hand, 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.
We also use other tracking technologies like web beacons (sometimes called "tracking beacons" or "clear gifs") and local storage. These are tiny graphics files that contain a unique identifier that enable us to recognise when someone has visited our websites or opened an email that we have sent them. You can find more information about cookies at http://www.allaboutcookies.org and http://[www.youronlinechoices.com]().
