Privacy

We collect no personal data. Your ZIP code, inputs and quote stay in your browser: they are kept in the part of the address after the #, which browsers do not send to any server, and the calculation runs on your device.

We set no cookies. The site's host may keep standard server logs (IP address, page requested) for security.

The heat pump and heat pump water heater pages include Rewiring America's rebate finder. If you type a ZIP code into it, it sends that ZIP code to Rewiring America (and any other details you enter in it) to look up rebates. Our own calculator never sends your ZIP anywhere.
