Cookies & tracking.
A straightforward website, with no advertising trackers or analytics cookies.
What your browser loads
Pages, images and fonts are served with the website. Small scripts run the navigation, location search, door-problem selector, photo viewer, call checklists and motion effects.
Cookies and storage
The website code does not set cookies, use local storage or session storage, or include third-party analytics and advertising scripts. Your location searches and selected door-problem tabs are not saved after you leave the page.
External links
WhatsApp contact links, photo sources and advice references take you to other services. Their own privacy and cookie policies apply when you visit them. WhatsApp is linked from the website, rather than embedded as a chat widget. Read our privacy information for how website contact links work.
