Private by design: everything runs inside your browser. Nothing you type or upload is sent to a server. We use cookieless Vercel page-view analytics; no file data is collected. Once the page has loaded the tool works offline.
Small, single-purpose tools for freelancers and small businesses, grouped by job. Each runs entirely in your browser.
For firms: put branded versions of these calculators on your own site with the White-Label Calculator Kit.
