Cookie Policy

What are cookies?

Cookies are small text files stored on your device by your browser when you visit a website. They allow the site to recognise you on return visits, remember your preferences, and (with your consent) measure how the site is performing.

Cookies we use

Essential

• dib-cookie-consent — stores your cookie banner choice (accept / essential only). Required for the site to remember your preference.
• dib-calculator-state — stores partially-completed calculator inputs so you can resume later. Local to your browser.

Analytics (consent-gated)

• Google Analytics 4 — anonymous usage statistics. Only loaded after you accept analytics in the cookie banner.
• Microsoft Clarity — anonymous heatmap and session-recording analytics. Only loaded after consent.

How to change your preferences

You can change your consent at any time by clearing your browser cookies for this site, which will re-show the consent banner on your next visit. You can also disable cookies entirely in your browser settings, though some site features (the calculator's resume-state, for example) won't work without them.

Third-party cookies

If you embed content from third parties (e.g. clicking a YouTube embed), those services may set their own cookies. We don't control those cookies — please refer to the relevant third party's policy.
