Calculator data
Every calculator on this site runs entirely in your browser. The values you enter are not sent to us or stored on our servers. If you use 'Copy link to this result', your answers are placed in that link after the # sign so it reopens your profile; that part of an address is not sent to web servers.
CRS assistant and voice input
The CRS assistant reads what you type and works out your score in your browser; we do not receive or keep the conversation. If you tap the microphone, your browser's built-in speech recognition turns your voice into text. Some browsers, such as Chrome, do this through their maker's speech service, under that company's privacy terms. PDF reports are created on your device and are not uploaded.
Server logs
Our hosting provider keeps standard access logs (IP address, browser, pages requested, time) for security and to keep the site running. Logs are kept for a limited period and are not sold.
Analytics and advertising
We may use privacy-respecting analytics and, in future, display advertising from third parties such as Google. If we do, those providers may use cookies to measure visits or show ads, and we will update this page and show a consent notice where the law requires it.
