Your data stays private. Everything you type runs locally in your own browser tab. Nothing is uploaded, logged, or stored on a server — close the tab and it's gone.

This tool processes everything client-side, inside your browser window, using standard arithmetic running in plain JavaScript the instant you click Calculate.
