Privacy

Your calculations stay in your browser.

No accounts, cookies, analytics, advertising scripts or input uploads are included in this version.

Calculation data

Values you type are processed by JavaScript on your device. The calculator does not send them to a server or save them in browser storage. Reloading normally restores example inputs, unless a calculation link is open.

Optional copying and sharing

Copy buttons use your browser’s clipboard only when you press them. Calculation links encode simple inputs in the URL fragment, after #calc?. That fragment is not part of the HTTP request sent when loading the page. It may be kept in your browser history and is visible to anyone you share the complete link with. Large data lists are not included in share links.

Hosting and external links

The hosting provider still receives ordinary page requests, which can include an IP address and browser information, and may process technical logs for delivery and security. This site has no application database. If you follow an external reference link, that website has its own privacy practices.

Future changes

If advertising or analytics are added, this page and any required consent controls must be updated before those services are enabled.
