Cookie Policy

Cookies enable us to identify your device, or you when you have logged in. We use cookies that are strictly necessary to enable you to move around the site or to provide certain basic features. We use cookies to enhance the functionality of the website by storing your preferences, for example. We also use cookies to help us to improve the performance of our website to provide you with a better user experience.

What are cookies?

For almost any modern website to work properly, it needs to collect certain basic information on its users. To do this, a site will create files known as cookies – which are small text files – on its users’ computers. These cookies are designed to allow the website to recognise its users on subsequent visits, or to authorise other designated websites to recognise these users for a particular purpose. Cookies do a lot of different jobs which make your experience of the Internet much smoother and more interactive. For instance, they are used to remember your preferences on sites you visit often, to remember your user ID and the contents of your shopping baskets, and to help you navigate between pages more efficiently. They also help ensure that the advertisements that you see online are more relevant to you and your interests. Much, though not all, of the data that they collect is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve user experience. Some websites may also contain images called ‘web beacons’ (also known as ‘clear gifs’). Web beacons only collect limited information, including a cookie number, a timestamp, and a record of the page on which they are placed. Websites may also carry web beacons placed by third party advertisers. These beacons do not carry any personally identifiable information and are only used to track the effectiveness of a particular campaign (for example by counting the number of visitors). Information collected by cookies and web beacons is not personally identifiable.
