Describe your windows

Two minutes. Everything you enter stays in this browser (nothing is sent anywhere) and turns the green box on every page into notes for your own windows. It also prefills the calculators and seeds the window survey. You can change it any time, and you can copy a link that carries your setup to another device.

Saved in this browser only. The share link encodes your answers in the address itself, so anyone you send it to sees your setup; nothing is stored on a server.
