Cookies and local preferences
What the website code stores
The light or dark appearance choice is kept in your browser under the key jc-theme. It is a device-local preference and is not used for advertising. Calculator and enquiry values are not deliberately saved by this website code, although your browser may offer its own form history.
What is not installed
The website has no analytics tags, advertising pixels, embedded Google review feed or social-media tracking widget. Fonts and images are served with the website. External links only open the relevant service when selected.
Hosting access and security
The hosting provider may use its own cookies or technical storage for sign-in, security or access control. Those platform functions are separate from the website’s theme preference.
Changing your preference
Use the theme button in the header to switch appearance. Clearing this site’s browser storage removes the saved preference. You can also control cookies and site storage through your browser settings.
