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. It may also store non-sensitive campaign attribution, such as the source or campaign that brought you to CrewMath. You can remove this information by clearing site data in your browser.

Share links

When you choose “Share scenario,” 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, and its analytics configuration strips calculator parameters before reporting a page location.

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 aggregate 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.

If you choose “Allow analytics,” CrewMath also loads Google Analytics 4 (measurement ID G-ZHCPQFTN6C). Google Analytics may use cookies or similar browser storage and receive technical and usage data such as page views, referral source, device information, and non-sensitive product actions. Those actions can include starting the calculator, viewing a result state, copying a result, sharing a scenario, or printing. CrewMath disables Google advertising signals and never sends the financial values entered into the calculator.

If you choose “Not now,” the Google Analytics tag is not loaded. You can change your saved choice at any time by selecting this button: Change analytics choice.

CrewMath does not currently show behavioral advertising. Advertising will not be activated until any required additional notices and controls are in place.
