What to do if you don’t want cookies to be set
There are a small minority of individuals who find the idea of a website storing information on their computer or mobile device a little bit nosey, especially when this information is stored and used by a third party without their knowledge. Even though this process is really quite harmless you may not, for example, want to see marketing which has been aimed at your interests. If you prefer, you're fully entitled to block some or even all of the cookies, you also have the power to delete cookies that have previosly been set; but you need to be aware that you the experience on the site may suffer along with possibly losing some functionality of the website too.
