Cookies help us to provide you with a better website by allowing us to monitor which pages you find useful and which you don't. However, a cookie doesn't give us access to your computer or any information about you, other than the data you choose to share with us.
You can change your browser setting to prevent cookies from being accepted, or, depending on which browser you are using, you might be able to receive an alert when a website is trying to place one on your browser. With most browsers you can allow first party cookies to be set, but refuse third party cookies. By not allowing cookies, some of our functionality might not work.
You can delete cookies stored in your browser by using a function in your browser. Whilst this does not mean you won't collect cookies in the future, it allows you to delete your cookies after you have been online. This is known as 'clearing cookies'.
