Information we collect
The calculator runs in your browser. We do not receive the numbers you type unless you voluntarily send them in an email.
Like most websites, our hosting or analytics partners may collect standard server logs (IP address, browser type, pages viewed). Refer to your network administrator if you need their retention schedule.
Cookies and analytics
We may use privacy-conscious analytics or advertising tags in the future. If enabled, those services set their own cookies subject to their policies. You can block cookies in your browser settings.
