This site renders a ray traced image in your browser. There are no accounts, no logins and no file uploads. The settings you choose (canvas size, sphere radius, colours, eye and light positions) are held in memory for the duration of your visit and are discarded when you close the page. Nothing you render is stored on the server.
This site uses GoatCounter, a privacy friendly analytics service, to get a rough idea of how many people visit. GoatCounter sets no cookies, does not track you across websites and does not build a profile of you. For each page view it records: the page address, the referring page (if any), your browser and operating system, your screen size and your country. Your IP address is used only to work out the country and to tell one visit from another within a single day; it is not stored.
The details are described in the
GoatCounter privacy policy
and GDPR notes.
If you would rather not be counted, block the domain gc.zgo.at in your
browser or content blocker, or run
localStorage.setItem('skipgc', 't') in your browser console once for this site.
One strictly necessary cookie is set (_ray_tracer_web_key). It holds a signed
session token used to protect the page against cross site request forgery. It contains no
personal data, is not used for analytics or advertising and expires when your browser
session ends.
The number of renders a single visitor can request is limited, so that the server stays usable for everyone. To enforce that, your IP address is held briefly in the server's memory along with a counter. It is not written to a database, it is discarded once the counter expires and it is not shared with anyone.
The hosting provider records ordinary web server logs (IP address, timestamp, requested page, browser identification) for security and troubleshooting. These are kept only as long as the provider needs them for those purposes.
Under the GDPR you have the right to access, correct or erase personal data concerning you, to restrict or object to its processing, and to lodge a complaint with your data protection authority. Since this site keeps no accounts and stores no identifiable records, there is normally nothing to retrieve or delete, but you are welcome to ask.
