Calculator inputs

Calculation requests are processed to return a result. We do not create a public result URL or attach the inputs to an account. If you choose “Save on this device,” the comparison is stored in your browser's local storage. You can remove it by resetting browser storage.

Messages and correction reports

Contact and correction forms store the name, email address and message you submit, plus a one-way submission hash used to limit abuse. We use this information to respond or review the report.

Server records

The hosting server may keep normal security and error logs, including an IP address and browser details. Retention depends on the hosting configuration and should be kept no longer than needed for operation and security.

Cookies

The application uses essential session and security cookies. No advertising or audience analytics service is enabled in this Phase 1 package. If that changes, the consent and privacy information must be updated before those services are activated.
