ERICH Calculators is designed so calculator inputs are processed in your browser. The current site does not require user accounts or payment information.
Web hosting providers may record standard technical information such as IP address, browser type, requested pages and timestamps. If analytics are added in the future, this policy should be updated to describe the service and data collected.
The calculators in this version run locally in your web browser and do not intentionally transmit the values you enter to a server.
