The short version

The CrewMath calculator runs in your browser. The financial figures you enter are not sent to or stored by CrewMath.

Local storage

Your browser may store your most recent calculator inputs on your device so they are available when you return. You can remove them by clearing site data or using your browser's privacy controls.

Share links

When you choose “Copy share link,” the calculator values are placed in the link's query string. Anyone with that link can see those values. CrewMath does not save a separate copy of the scenario.

Hosting logs

Our hosting provider, Cloudflare, may process standard request information such as IP address, browser type, requested page, and security signals to deliver and protect the site. See Cloudflare's privacy policy for its practices.

Analytics and advertising

We use Cloudflare Web Analytics to measure page views, visits, referral sources, device types, and page performance. Cloudflare describes this service as privacy-first and says it does not collect or use visitors' personal data. The calculator values themselves are not included in analytics events. CrewMath does not currently use behavioral advertising or tracking cookies.
