2. What are cookies

Cookies are small text files that are placed on your device when you visit a website. They are widely used to make websites work, to make them more efficient, and to provide information to the site's operators. Similar technologies, such as local storage and pixels, work in comparable ways. We refer to all of these as 'cookies' in this policy.

We aim to use as few cookies as possible. The cookies we may use fall into the following categories:

5. Managing your cookies

Where we use non-essential cookies, we will ask for your consent before setting them, and you can change your preferences at any time.
