HOME PROJECT / OUR APPROACH

Privacy

Your project measurements remain in this page.

Updated October 9, 2026.

What this site collects

The calculators do not send measurements, costs or results to an API. There is no database, account registration or application storage of your inputs. Refreshing the page resets the calculator.

Hosting and links

The hosting provider may process ordinary request information, such as IP address and browser details, to deliver and secure the site. Private previews may require the hosting provider’s sign-in; that sign-in is separate from these calculators. External reference links have their own privacy policies.

Copying results

Copy acts only when you select it and writes the selected result to your clipboard.

Advertising and cookies

This site may show ads served by Google AdSense. Google and its partners use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.

You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of some third-party vendors’ use of cookies at aboutads.info. Learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.

Where required, such as for visitors in the European Economic Area, the UK and Switzerland, a consent message will ask for your choice before advertising cookies are used.

Future changes

If we add analytics or other third-party services, we will update this notice before they are enabled. Calculator inputs will continue to stay in your browser.
