Cookie policy

This policy explains the cookies and similar storage that Double Glazing Zone uses, and why. A cookie is a small text file stored on your device by your browser.

First-party marketing-attribution cookies

When you land on the site we set first-party cookies (and matching browser localStorage entries) so we can tell which marketing campaign referred you and keep that attribution if you move around the site or return later. These are named with a wml_ prefix and store the UTM campaign values (source, medium, campaign, term, content), the landing page, and advertising click identifiers such as Google (gclid) and Meta (fbc/fbp) ad click ids. They are set for 90 days.

Analytics and tag-manager cookies

We do not currently run a tag manager or analytics tags on this site. If we enable a tag manager (for example Google Tag Manager) in future, it may set additional cookies — such as Google Analytics (_ga, _ga_<id>) — and this policy will be updated to list them before they are used.

Managing cookies

You can delete or block cookies through your browser settings. Blocking the attribution cookies above will not stop the quote form working; it only means we cannot tell which campaign referred you.
