Cookie Policy
This policy explains the cookies and similar storage that Double Glazing Offers uses on this website. Cookies are small files stored on your device that help the site work and help us understand where our enquiries come from.
Cookies we set
When you land on the site we store first-party marketing-attribution values so that, if you submit a quote request, we can credit the campaign that referred you and guard against fraudulent or duplicate submissions. These are stored in first-party wml_* cookies (and, where available, your browser's local storage).
| Cookie | Purpose | Expiry |
|---|---|---|
wml_utm_source, wml_utm_medium, wml_utm_campaign, wml_utm_term, wml_utm_content |
Remember the marketing campaign values (UTM parameters) from the link you arrived on. | 90 days |
wml_gclid, wml_fbc, wml_fbp and other advertising click identifiers |
Remember ad-click identifiers so a genuine enquiry can be attributed to the correct advert. | 90 days |
wml_landing_url |
Records the first page you arrived on for attribution. | 90 days |
Analytics and tag manager
We may in future enable a tag manager (such as Google Tag Manager) to run analytics tags. When enabled, those tags may set their own cookies — for example Google Analytics cookies (_ga, _ga_*) used to measure visits, and advertising cookies used to measure campaign performance. This table will be updated to list them once they are switched on. Until then, no such tags are active.
Managing cookies
You can delete or block cookies through your browser settings. Blocking our wml_* attribution cookies will not stop the site working or prevent you submitting the quote form.
