FAQ

Is it really free?

Yes, completely free. No account required and no watermarks on the calculator itself. The code includes a one-line "Calculator by Cashsembly" credit under the calculator; please keep it.

Do I need to update the data myself?

No. Our automated system pulls fresh rates from official sources every 24 hours. You embed once and it stays current forever.

Can I use it on any website?

Yes โ€” WordPress, Squarespace, Webflow, custom HTML, or any platform that allows iframe embeds.
