Privacy

All entered dates, calendar calculations and optional 3D processing stay in your browser. This website has no upload, accounts, app history, local-storage persistence, analytics collector, advertising code or third-party runtime request.

Clear removes the current input and result. Your browser may restore form fields independently during navigation. The optional 3D renderer is bundled locally with its license; disabling it disposes its canvas while the calculator remains usable.

Downloading an SVG creates a local file containing the dates you entered. Share that copy only deliberately. Temporary view URLs are released when the result is cleared or the page leaves. The count-only local completion event has no data payload and no current collector.

The app uses your browser’s local date as the default reference date. It does not request your location, camera, microphone, editor, files or account access.
