Cookies and Measurement
This page explains site measurement, advertising preferences and how to change them. For form data, see Privacy and Data Protection.
Last updated: 1 November 2026
What happens on your first visit?
The preference panel never opens by itself. The preference icon is hidden during the opening film and appears when you skip it or after the skip option leaves the screen; use the icon to open the panel. Google Analytics starts before you make a choice; on customer-specific quote pages, which only people who receive the link see, Microsoft Clarity starts as well. Google Ads and Meta Pixel do not load until you explicitly allow them. Cloudflare Web Analytics also measures visits and page performance. Google may process your IP address, page address and browser/device information; Meta may also do so once Advertising is turned on. The Measurement switch turns off Google Analytics (and Microsoft Clarity on quote pages); the single Advertising switch turns Google Ads and Meta Pixel on or off together; it is off by default. Cloudflare Web Analytics works independently of these switches. Visit measurement with Umami does not use cookies. It is not tied to the switches in the preferences panel. Details are on the Privacy page.
Measurement and advertising preferences
Google Analytics uses cookies to measure page views by default. If you turn measurement off, new page-view events stop, Analytics cookies are removed and Analytics measurement will not start on subsequent page loads. An already loaded tag may still send technical consent signals. On the site’s general pages we send only page-view events to Google Analytics, rather than separate Analytics events for watching the film or submitting an application. On customer-specific quote pages we also send interaction events such as section views, scrolling, time on page, option changes and contact clicks; these events carry no personal information or form values. On these pages, while Measurement is on, Microsoft Clarity records heatmaps and sessions with form content masked; Clarity data is transferred abroad to Microsoft and stops when you turn Measurement off. Google Analytics may also process technical session and usage signals. We use Google Ads and Meta Pixel to measure advertising performance, successful contact requests and ATLAS beta applications, and to use visit information for ads relevant to your interests, including on Facebook and Instagram. Advertising is off by default; Google Ads and Meta Pixel do not load unless you turn it on. You can turn it on or off separately from measurement. Turning advertising off stops new application advertising events and removes the site's Google Ads and Meta cookies. An already loaded Google tag may still send technical consent signals. This site setting does not delete cookies on Meta's own domains.
The switches save as soon as you tap them; there is no separate save step. Closing the panel leaves your existing settings unchanged. Measurement is on by default and advertising is off; your previous measurement choice is preserved. An advertising choice previously saved as “on” is not treated as an explicit choice, and advertising starts off.
Application measurement
Conversion events are sent only after the server confirms a successful submission. These events do not include your name, email address, telephone number or message; they use the submission type and a random transaction identifier. Meta receives one page-view event per actual page load and the application type and a random transaction identifier after a successful submission. Google and Meta may process IP address, visited page address, browser and device information. Enhanced matching and Meta's automatic form events are not used.
