Privacy

Your calculator inputs stay in your browser.

This version contains no accounts, application database or input uploads.

Calculation data

Values are processed by JavaScript on your device. The site does not save calculator values in browser storage. Optional calculation links put simple inputs after the URL # fragment; anyone you share the full link with can read them.

Hosting

The hosting provider still receives ordinary page requests and may process technical delivery/security logs such as IP address and browser information. If analytics or advertising are added later, this page and any required consent controls should be updated first.
