What is a cookie?
A cookie is a small amount of data, which often includes a unique identifier that is sent to your computer or mobile device (referred to here as a "device") browser from a website's server and is stored on your device's hard drive. Each website or third party service provider used by the website 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 website or third party service provider to access the cookies it has already sent to you, not the cookies sent to you by other sites or other third party service providers. A cookie will contain some anonymous information such as a unique identifier and the site name and some digits and numbers. It allows a website to remember things like your preferences or to identify your device for analytical and tracking purpouses.
How can I control cookies?
There is further guidance available on the website www.aboutcookies.org which tells you how to control and remove cookies using the options available in your web browser.
