Current data status

No collection yet.

The current static build has no account system, email form, payment system, advertising pixel, or third-party analytics tag.

Local behavior

What the page does.

The calculator performs arithmetic in the browser. It does not transmit the entered values. Navigation code marks the current page and can emit a local in-browser event for interface testing. The event is not sent to any server, analytics provider, or third party.

Before change

Collection requires a policy update.

Before email capture, analytics, payments, accounts, or submissions are enabled, this page must identify the provider, fields collected, purpose, retention period, deletion/contact method, cookie behavior, and relevant disclosures.

Do not rely on this draft after a data service is added. Update and test the policy before activating collection.
