How the embeds work
You can use a plain iframe or the lightweight CalcMentor loader script. The iframe option is the most predictable. The script option creates the iframe for you, adjusts height automatically and adds a visible CalcMentor credit link.
Attribution and link policy
Please keep the calculator attribution visible for users. The credit should use natural wording such as "Calculator by CalcMentor" or "Open the full calculator on CalcMentor". Do not hide the link, use keyword-stuffed anchor text, or place it where visitors cannot see it. If your site policy requires qualifying outbound links, you may use a nofollow or sponsored link attribute.
Privacy and third-party loading
Embedded calculators load an iframe or script from CalcMentor. That means CalcMentor may receive normal technical request data such as IP address, browser information, requested widget URL and referrer. Some widgets also fetch third-party reference data, such as exchange rates or public holidays, when the visitor uses the tool.
