In short
This site sets no cookies, runs no analytics or advertising scripts, has no accounts and no forms. The calculators run in your browser; nothing you type is sent anywhere. The only data that exists is the web server's standard access log (IP address, page requested, time, browser string), kept for security and deleted on rotation.
Third parties
Pages load no third-party scripts, fonts or images. The gold price shown was fetched by our server from a public price feed at build time, not by your browser. If we add an analytics tool or an affiliate link that sets a cookie in the future, this page will say so before it happens, and the disclosure page will name the partner.
If you write to us, we keep the message to answer it and to fix the page you wrote about. We do not add addresses to any list.
