The calculators do not send your inputs or generated CSV files to the server. Results are stored in sessionStorage in the current browser tab for up to 30 minutes. Closing the tab ends that session. Browser or device access may expose the results to other users of the device.
The web server receives ordinary HTTP request information when you open pages. Your chosen interface language and result identifier can appear in page URLs. Result identifiers do not contain calculation inputs.
