Short version: the calculators run in your browser and we do not ask for, store or sell personal data.
Calculator inputs
Numbers you type into a calculator are processed in your browser. They are not sent to our server or saved.
Server logs
Like any website, our hosting keeps standard technical logs (IP address, browser, page requested, time) for security and troubleshooting. They are kept for a limited period and not used to identify you.
Cookies
This site does not set advertising or tracking cookies.
Affiliate links
