Calculator data
Dimensions you enter into the area calculator are processed in your browser by JavaScript. This implementation does not submit those dimensions to a dedicated calculation server.
Google Analytics
This website uses Google Analytics 4, provided by Google, to understand page visits, approximate visitor geography, traffic sources, and engagement. GA4 loads when a page opens and may process browser and device information or use cookies and similar identifiers according to Google's policies. This site does not display an analytics consent popup or analytics-preferences control.
The site removes URL parameters containing calculator inputs from the page-location field sent to GA4, retaining only common campaign attribution parameters. Visitors can use browser privacy settings or content-blocking tools to limit analytics requests.
Google's information about its data processing is available in the Google Privacy Policy. The website does not currently have an advertising or Google Tag Manager integration in its source code; any future integration should prompt an update to this notice.
Technical information
Hosting providers may process standard request data, such as IP addresses, timestamps, and browser details, to deliver the site and protect infrastructure. Their retention and processing policies apply.
