Your choice
This website works without any optional cookies. There are two optional kinds, analytics and advertising, and each is set only if you allow it in the banner shown on your first visit: accept all, reject all, or choose one. Rejecting takes one click and changes nothing about how the site works.
If your browser sends a Global Privacy Control signal, we treat it as a refusal and do not show the banner. You can still allow them with the button above.
Always on
These are needed for the site to work and to keep it secure, so they do not ask for consent.
| Name | Set by | What it does | Kept for |
|---|---|---|---|
dv-consent | This site (local storage) | Remembers whether you accepted or rejected analytics | 12 months |
cf_clearance, __cf_bm | Cloudflare | May be set when a form is protected from automated abuse | Up to 12 months |
Analytics, only if you allow it
These help us see which pages are read and where people get stuck. Microsoft Clarity also records visits as heatmaps and session replays. What you type into our forms is masked and is not recorded.
| Name | Set by | What it does | Kept for |
|---|---|---|---|
_ga | Google Analytics | Tells one visitor from another | 2 years |
_ga_* | Google Analytics | Keeps a visit together across pages | 2 years |
_clck | Microsoft Clarity | Tells one visitor from another | 1 year |
_clsk | Microsoft Clarity | Joins the pages of one visit into a single recording | 1 day |
CLID, MUID, ANONCHK, MR, SM | Microsoft (clarity.ms, bing.com) | Recognise the browser across sites that use Clarity | Up to 1 year |
Advertising, only if you allow it
These let Google Ads tell us which of our ads led to an enquiry, and show our ads again, on Google and on sites that work with Google, to people who have visited this site (remarketing). They are set through Google Analytics.
| Name | Set by | What it does | Kept for |
|---|---|---|---|
_gcl_au, _gcl_aw | Google Ads (through Google Analytics) | Remember that the visit came from one of our ads, so an enquiry can be counted against that ad | 90 days |
IDE, ar_debug | Google (doubleclick.net) | Recognise the browser so our ads can be shown again to past visitors, and measure those ads | Up to 13 months |
Google and Microsoft may change the cookies their tools set. Who receives this data and how long it is kept is in our Privacy Policy.
What we do not use
No social media trackers, and no advertising of any kind on this site itself.
