What are cookies?
A cookie is a small file of letters and numbers which is put on your device when you access a website.
Cookies are widely used in order to make sure websites work effectively, as well as to store information about your preferences or past actions.
There are two broad types of cookies - 'first party cookies' and 'third party cookies'. First party cookies are cookies are served directly by our website to your device and are often used to recognise your device when it revisits that site and to remember your preferences as you browse the site.

In addition, cookies may be either 'session cookies' or 'persistent cookies'. Your computer automatically removes session cookies once you close your browser. Persistent cookies will survive on your computer until an expiry date specified in the cookie itself, is reached. We use both session and persistent cookies.

Third party cookies
