The Boiler Feed Pump Calculator executes all physics formulations and temperature-density lookups entirely within your local web browser. No sizing inputs, boiler generation rates, pressure inputs, or calculation reports are transmitted to or stored on our servers.
This website does not use tracking cookies or marketing pixels. We utilize standard browser localStorage solely to persist your theme preference (Light Mode vs. Dark Mode) across sessions.
When you download the PDF sizing report, the document is generated client-side using JavaScript libraries (jsPDF) running directly on your CPU. No report data leaves your machine.
We run a clean, server-side count of requests to prevent spam. No persistent personal identifiers or IP logs are associated with calculations.
