Cookies are small text files stored on your device by a website. Similar technologies, such as browser local storage, work in much the same way. This policy describes what this website stores and how you can control it.
STRICTLY NECESSARY STORAGE
We store a single preference in your browser's local storage to remember whether you accepted or rejected optional analytics. Without it, we would have to ask you on every visit. This is not used to identify you and is not shared with anyone.
OPTIONAL ANALYTICS
With your agreement, we use Google Analytics 4 to understand, in aggregate, which pages are useful and how visitors find us. Google Analytics can set cookies with names beginning with _ga after you accept. Analytics scripts are not loaded at all unless you choose "Accept analytics". If you choose "Reject optional", no Google Analytics script is loaded and we only remember your consent preference. Google explains its processing in its privacy policy.
CHANGING YOUR MIND
You can change your choice at any time by clearing this site's data in your browser settings; the consent message will then appear again on your next visit. Guidance on managing cookies is available from the Information Commissioner's Office.
For more on how we handle personal data, read our privacy policy. Questions about this policy can be sent via Contact Us. We will update this page if the way we use cookies changes, and the date at the top will show when it was last revised.
