1. What is a cookie?
A cookie is a small text file saved in your browser when you visit a website. Similar technologies include your browser's local storage and tracking pixels. They're used to keep you signed in, remember your preferences or measure how you use the site. Personal data such as your IP address and device information may be processed through cookies.
2. Your cookie choices
- The first time you visit the site, a cookie preferences window opens. There you can choose Accept all, Reject all or pick by category. Rejecting cookies doesn't stop you from using the site.
- Apart from strictly necessary cookies, cookies run only in the categories you allow, and only after you allow them. Google tags start with consent set to "denied" by default (Google Consent Mode v2).
- You can change your choice or withdraw your consent at any time using the Cookie preferences link at the bottom of the site.
