Your calculations stay in your browser
The initial version of Metal Calculators has no advertising, no inquiry forms, and no third-party Analytics. Calculations run in your browser without sending the values you enter to us.
No advertising, inquiry forms, or third-party Analytics
We do not use advertising trackers, collect sales inquiries through the site, or load a third-party Analytics service in this initial version.
Calculation inputs are processed in your browser
Dimensions, material choices, quantities, and results are processed on your device. The calculator does not upload those values to our servers.
History and preferences are stored only on your device
Recent calculation history is saved locally only after you choose to enable it; switching history off deletes that saved history. Unit-system and display-precision preferences may also be kept locally so the site can remember your settings.
Share parameters use the URL fragment
When you create a share link, supported calculation parameters are placed after the # in the URL fragment. Browsers do not send that fragment to the hosting server as part of the page request. Anyone who receives the full link can still read its parameters, so do not include confidential information.
Hosting may process necessary request logs
The hosting service may process technical request data needed to deliver and protect the site, such as an IP address, request time, requested page, browser information, and security or error records. These logs do not contain calculator values held only in the browser.
