Calculator data
The core calculations run inside your browser. We do not send room dimensions, BTU values, electrical power or electricity rates to our own database.
Share links
When you press “copy result link” or “copy this scenario,” the input values are added to the URL so you can reopen the case. The calculator does not send that link to us, but anyone you share it with can see it, and the page address may appear in ordinary web-hosting logs.
Technical logs
The hosting network may process ordinary technical information such as IP address, request time and User-Agent for security and operation under the infrastructure provider’s policies.
