Cookies
Marks on the wall. No tracking behind your back.
The worldwidewc.com application sets no cookies and uses no localStorage, sessionStorage, advertising pixels or browsing analytics tools. It does not fingerprint your device. Tools, colour and the presence token are held only in JavaScript memory during the visit. The wall position and zoom appear in the page address so you can return to or share that corner: these coordinates refer to the wall, not your geographic location. A temporary copy of the token is stored on the server for the counter described on the Privacy page, without tracking browsing activity.
Language
The suggested language comes from your browser preferences. Footer links let you change it. The page address carries your choice, with no language cookie or IP geolocation.
Infrastructure
Hosting may use technical mechanisms necessary for security or delivery. These are separate from the wall’s code. The application activates no optional trackers, so there is no meaningless “accept all” button. Adding trackers requiring consent would require a prior choice with equally accessible refusal and withdrawal.
