We use a small number of cookies on this site.
Region preference
A cookie named wpsc_region remembers whether you are viewing the UK or US version of the site, for up to one year. This exists purely for convenience - it does not track you across other sites, and you can switch region manually at any time using the region switcher in the site footer regardless of what the cookie currently says.
What we don't use
We do not use advertising cookies, third-party analytics cookies, or cross-site tracking pixels.
Managing cookies
You can delete or block cookies at any time through your browser's settings. Doing so may simply mean the site asks for your region preference again on your next visit - it won't break anything else.
