FAQ

Widget questions

Q1Is it really free?
Yes. Embed as many calculators as you like, on as many pages as you like. We only ask that you keep the small “by KleverKlimb” credit link.
Q2Will it slow down my site?
The widget loads lazily — only when a visitor scrolls to it — and runs entirely in the visitor’s browser.
Q3Do I need to update it when fees change?
No. The widget always shows the current version of the calculator, including updated default fees.
Q4Does the widget collect my visitors’ data?
No. Calculations happen in the visitor’s browser and the widget shows no ads.
