Privacy

What we collect here

Nothing. There are no accounts, no forms, no cookies, no analytics and no requests to other companies' servers. Fonts, sounds and graphics are all made on your device.

What stays in your browser

The page remembers a few settings on your own device, using local storage. They are never sent to us.

• Whether sound is on or off, and the volume.
• For the length of your visit only (session storage): that you have already seen the start-up animation.

Clear your browser's site data to remove them. The page works fine if storage is blocked.

What the host sees

Like every website, the service that delivers these files keeps ordinary access logs (time, address and the page requested) for security and abuse prevention. We do not use them to identify visitors.
