Cookie Policy

We use browser local storage under the key huansi-global-cookie-consent-v1 to remember whether you allow optional analytics and when you made that choice. This preference is necessary for the choice controls to work. It remains until you change your choice or clear your browser storage.

When a page URL contains campaign parameters, the site may store them under huansi-global-utm-v1 in browser session storage. If you submit an enquiry during that session, these parameters are sent with it so we can understand how the enquiry reached us. Session storage generally ends when the browsing session ends.

Cloudflare Web Analytics is loaded only when you choose “Accept analytics”. It provides aggregate information about site visits and performance; we do not use it to build advertising profiles. You can change this choice through “Cookie preferences” in the footer. Choosing “Essential only” leaves the analytics script unloaded.

Some pages offer YouTube videos. The YouTube player is loaded only when you choose to view a video. YouTube may then use its own cookies or similar technologies under its policies. Local video files do not require YouTube.

Use the footer control to change optional analytics at any time. You can also clear local or session storage and manage cookies in your browser settings. For more about how we handle personal information, read our Privacy Notice.
