Privacy

This site has no accounts, no forms on any page and no advertising. A visit leaves two small things behind: a list in your own browser, and a page-load measurement at Cloudflare. This page says what each one is.

Who runs the site is on the about page. Anything here that is wrong, corrections says how to tell us.

In your browser

Which machines you have opened, and which you have worked

The studio index marks the machines you have already visited, and the random pick tries to avoid ones you have seen. To do that it keeps one list in your browser's local storage, under the name la_visited_machines. The list never leaves your browser; nothing on this site reads it back to a server.

To remove it, clear this site's data in your browser settings. If storage is blocked, the site works the same and simply forgets you between visits.

The settings you give a machine

A machine writes its settings into the page address after the #, so that a link reopens the state you were looking at. The part of an address after the # is not sent to a server when a page is requested. It goes only where you paste the link.

Cookies

This site sets none. On 2026-10-13 a fresh browser loaded a machine page, waited, and held no cookies for this site.

At Cloudflare

What the measuring script is

Cloudflare serves this site, and its network adds a small script to each page, beacon.min.js, from static.cloudflareinsights.com. It is Cloudflare Web Analytics. The pages in this repository do not contain it and do not need it.

Cloudflare describes the script as collecting timing metrics, so the site's owner can see how fast pages load, and it reports the Core Web Vitals when a page first becomes hidden after it has loaded, for example when you switch tabs. It also counts page views. Cloudflare states that it does not track individual people across the sites of its customers, and that it avoids cookies and local storage for tracking and does not fingerprint visitors.

How long it is kept

Cloudflare's documentation says it keeps the unsampled data for the past 7 days, after which the data is aggregated down to around 10%, and that the previous six months can be viewed. Those are Cloudflare's figures, not ours, and they are read from its documentation rather than measured here.

How to stop it

There is no switch on this site, because Cloudflare adds the script as the page passes through its network, so there is no code of ours to turn off. A browser or content blocker that blocks static.cloudflareinsights.com stops it. Nothing on the site depends on the script, so blocking it breaks nothing.

What Cloudflare sees as the host

Any host sees the requests it serves: the address that asked, the page asked for, and the browser. Cloudflare handles those under its own terms. The pages themselves send nothing to any other service; the site's security policy allows connections only to this site and to Cloudflare's measuring service.

Writing to [email protected] sends an ordinary email, which is read by the person responsible for the site and used to reply. The corrections page says what to include.
