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.
| Cookie | Purpose | Expiry |
|---|---|---|
wml_utm_source, wml_utm_medium, wml_utm_campaign, wml_utm_term, wml_utm_content | Record the marketing campaign that referred you. | 90 days |
wml_gclid, wml_fbc, wml_fbp and similar | Store advertising click identifiers so a conversion can be attributed to the correct ad. | 90 days |
wml_landing_url | Remember the first page you arrived on. | 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.
