The short version

WorthMath does not require accounts and does not collect, store, or transmit anything you type into the calculators. All calculations run locally in your browser.

Calculator inputs

Numbers you enter into any calculator on this site are processed entirely on your device. They are never sent to our servers, logged, or shared with anyone.

Advertising and cookies

This site may display advertising served by third parties, including Google AdSense. Third-party ad vendors may use cookies or similar technologies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve personalized ads; you can opt out of personalized advertising in Google's Ads Settings. For more detail on how Google uses data from sites that use its services, see policies.google.com/technologies/partner-sites.

Analytics

We use PostHog to understand page visits and whether a calculator is used. Calculator inputs and results are not included in analytics events. Automatic interaction capture and session recording are disabled. Where consent is required, analytics starts only after the relevant consent signal is received. PostHog may process pseudonymous browser data as described in its Privacy Policy.
