For this one request, quidam's server sees your real address. It keeps nothing.
your local network
needs your permission
Your browser may ask for permission before this page can reach devices on your home network, and saying no is a valid answer: it means the protection works. A website cannot see MAC addresses, device names or Wi-Fi details. Only an installed app can.
