Privacy

The calculator requires no account and asks for no personal information. You can use every feature without identifying yourself.

What is collected

Anonymous usage records: the values entered into the calculator, the results produced, and the calculator version. These show which configurations people size for and where the tool is confusing, which is how it gets better.

What is not collected

No names, no email addresses, no accounts. No advertising or tracking cookies. Nothing is sold or shared with third parties. Usage records carry no identifier that ties them to a person or a company.

Changes

If features are added that require personal information — saved projects or an emailed spec sheet, for example — that will be an explicit choice presented at the time, with its own consent, not a quiet change to this page.
