Cookie policy

We use cookies and local storage for two things: making the site work, and understanding in aggregate which pages are useful. We do not use them to build a profile of you, to follow you across other websites, or to sell anything about you to anybody.

With your permission, and only then, we also measure how our marketing performs — for example, whether a visit from one of our ads led to an enquiry. You are asked the first time you visit, the answer is no unless you say yes, and you can change it at any time.

If you block all cookies, this site still works. You may lose the assistant remembering your conversation across a page navigation, which is the extent of the degradation.

We use optional measurement tools to learn whether our advertising leads to enquiries. The tool we currently use is OpenAI’s measurement pixel. It runs only if you choose Accept in the cookie banner. Until then, and if you choose Reject, it sends no measurement and sets no cookies. Your browser does still download the pixel script from OpenAI’s servers, as it would any file the page loads.

If you accept, the pixel sets two first-party cookies: __oppref, which holds an attribution identifier from the ad link you followed, and __obref, a randomly generated reference for your browser on this site. When you submit a contact, quote or assessment form and we have stored it, we report that a lead was created. That report contains the event type only — not your name, email address, phone number, company or message.

If you change your mind, choose Cookie settings in the footer and then Reject. Measurement stops immediately and the pixel removes both cookies.

• Advertising pixels other than the consent-based measurement described above
• Retargeting or audience-building
• Social media tracking widgets
• Data brokers or audience-selling networks
• Session recording of form input

Every major browser lets you block or delete cookies and clear local storage, usually under privacy settings. Advertising measurement is the only thing we ask about, and you can change your answer here: Cookie settings.

If you would rather not be counted in aggregate analytics at all, enabling your browser’s Do Not Track or blocking the analytics domain is sufficient — we do not attempt to work around either.

Apart from OpenAI's pixel when you have accepted it, the pages that embed a third party — the booking scheduler and the payment checkout — are the only places another party can set a cookie. All three are listed on the sub-processors page, and the booking scheduler is loaded in an iframe so nothing runs before you interact with it. Questions: [email protected].
