Short version: the calculator runs in your browser and we collect almost nothing.
We do not ask for your name, and we do not see the numbers you type into the calculator itself. Anonymous, cookieless analytics may count page views so we can keep the pages fast. If you email us, we keep the message only to reply. If you use the optional "Email me my results" form, we collect your email address as described below.
If you use the "Email me my results" form, we collect your email address and the time you gave consent. We use it to send your results and occasional tips about our free tools. We never sell your email address. Every email includes an unsubscribe link. You can also request deletion of your data at any time by emailing n.harvard@aitechpros.ai.
We do not sell data, and we never sell your email address.
