Cookie policy
This website is designed to work without advertising cookies or cross-site tracking.
What this site stores
When you dismiss the cookie notice, the site stores a small preference called healison-cookie-notice in your browser’s local storage. This prevents the same notice being shown on every visit. It is not used to identify you or track you across websites.
Essential technology
Hosting and security providers may process limited technical information, such as IP address, browser information and request logs, to deliver and protect the website. Strictly necessary technologies do not require consent under UK rules.
Analytics and marketing
This version of the site does not intentionally set analytics, advertising or marketing cookies. If these tools are introduced later, the cookie notice and consent controls will be updated before they are enabled where consent is required.
Managing your preference
You can clear site data through your browser settings to show the notice again. Blocking essential storage may affect how preferences are remembered.
