Terms of use

You may embed Calcadian calculators on any public or internal website at no cost.
Please keep the small attribution line (calculator name + Calcadian link) intact.
Don't wrap the iframe in a way that obscures branding or implies endorsement.
We may update calculator UI or behavior; we won't break the embed URL pattern.
