Widget FAQ
Is the widget really free?
Yes. There is no sign-up, no fee, and no limit on page views. We ask only that you keep the one-line credit under the calculator.
Does the widget show ads or track my visitors?
No. The widget loads no ads, no analytics, and sets no cookies. Everything a visitor types stays in their browser and is never sent to us. The widget loads the Geist font from Google Fonts, like the rest of our site.
Will it work on WordPress, Squarespace, Wix, or Webflow?
Yes. Paste the code into an HTML block. If your site builder removes scripts, turn off auto-fit height: the calculator still works inside a fixed-height frame.
Does it work on phones?
Yes. The calculator adapts to the width of your page, and auto-fit keeps the frame exactly as tall as the calculator, with no inner scroll bars.
Can I change the default values or colors?
Not yet. Every widget opens with the same defaults as the calculator page. Visitors can change any value.
What happens when you update a calculator?
Your page updates automatically. Formula fixes and improvements reach your widget without any change to your code.
By embedding a widget you agree to our terms: use it on any lawful website, keep the credit line, and do not present the calculator as your own.
