What cookies are
Cookies are small text files placed on your device when you visit a website. They let the site remember things such as whether you are signed in. We also use similar browser storage for the same purposes.
Advertising measurement
We use Google Ads conversion tracking to see whether our advertising leads to enquiries and calls. Nothing is set until you choose Accept on the cookie banner. If you choose Reject, Google's cookies and identifiers stay switched off. You can change your choice at any time using the Cookie settings link in the footer. We run no other analytics, no Meta pixel and no heatmap or session recording tool.
Cookies we use
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
| Auth session storage | Supabase stores the signed-in editor session in browser localStorage so the CMS stays authenticated securely. This is only set when an editor signs in at /auth. | Session to 7 days | Strictly necessary |
| Admin sidebar preference | Remembers whether the admin sidebar is open or collapsed. Only set inside the signed in editor area, never for public visitors. | Up to 1 year | Functional |
| session-id | Set by our hosting platform to tie the requests made during one visit together, so pages are served and delivered consistently. It carries no marketing or analytics data and is not used to identify you. | Ends when you close your browser | Strictly necessary |
| __dpl | Set by our hosting platform to record which deployment of the site served your request, so all files on a page come from the same version. | 24 hours | Strictly necessary |
| Cookie choice | Remembers whether you accepted or rejected advertising cookies, so you are not asked again on every visit. | Until you clear your browser storage | Strictly necessary |
| Google Ads (_gcl_au, _gcl_aw, _gcl_dc and related) | Set by Google to measure whether an advert on Google led to an enquiry or a call to us, and to support conversion measurement and remarketing. Only set if you accept cookies. | Up to 90 days | Advertising |
| Google conversion linker (IDE, test_cookie, and similar on doubleclick.net) | Set by Google on its own domains when a Google advert is measured, to link the advert click to the action taken on this site. Only set if you accept cookies. | Up to 13 months | Advertising |
Managing cookies
Every major browser lets you block or delete cookies from its settings or privacy menu. Blocking strictly necessary cookies will stop the sign-in area working properly. Public visitors, including anyone using the contact form, can browse and enquire with cookies blocked entirely.
