Privacy policy

Panel Sizer has no accounts and asks for no personal information. This page describes what is sent to our server when you use it.

What you send

When you click Calculate Panel Size, your browser sends the numbers on screen to our server: floor area, circuit counts, conductor material, method, phase, and the name, wattage and voltage of each appliance. None of this identifies you.

The server runs the calculation, returns the result and keeps no copy. It has no database. Your entries disappear when you close or reload the page.

What we do not do

No sign-in, no user accounts.
No cookies and nothing saved in your browser's storage.
No analytics, advertising or tracking scripts.
No third-party fonts or embeds; the intro video is served from this site.

Hosting logs

The site and its server run on Microsoft Azure. As with any website, the host records standard request logs (IP address, time, the page requested and browser type) for security and troubleshooting.

Changes and questions

If the tool starts handling data differently, this page will be updated first. Questions go to the lab through the contact page.
