Privacy

Your figures. Every calculation on this site happens in your own browser, on the page. The car details, prices, exchange rate and port charges you enter are not sent to a server, not stored, and not visible to us. Close the tab and they are gone; the print button prints from your browser for the same reason.

Usage statistics. At launch this site runs no analytics script at all — the configuration slot for one exists in the build, empty, and the privacy position will be updated here before any measurement tool is switched on. If one is added later, it will be aggregate usage statistics (pages visited, approximate region), it will never receive anything typed into a calculator, and this page will say which tool it is.

Advertising. Pages carry clearly marked advertisement placeholders. No ad network is connected at launch, so nothing loads from one; when that changes, this page will name the network and its data practices before the slots go live.

Links out. DutyMath links to official and reporting sources. Those sites run their own privacy policies; nothing about your visit here is shared with them by us.

Questions about any of this: the contact page carries the current address and its status.
