The widget is free for commercial and personal use. The only requirement is that the small "Powered by concretecalculators.org" attribution link stays visible and clickable. The widget is served from our domain, so improvements arrive automatically without you touching your site, and it never sets cookies or collects data from your visitors — all math runs in their browser.
