Cookies

A cookie is a small amount of data which often includes an anonymous unique identifier that is sent to your browser from a website’s computer and stored on your computer’s hard drive. Each 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 to access the cookies it has already sent to you, not the cookies sent to you by other sites. Many sites do this whenever a user visits their website in order to track online traffic patterns and record information about your online preferences. This website in its current state uses session cookies, and the table below explains the use of these cookies and why they are used:
