Privacy

All calculations on this site run locally in your browser. The values you type are never sent to a server, logged or stored.

This site does not use accounts and does not set tracking cookies. Your theme preference (light/dark) is stored only on your own device.

Our hosting provider may keep standard, anonymised access logs (such as request timestamps and status codes) to operate the service. External links to partner sites are regular links; those sites have their own privacy policies.
