What is stored

One flag in your browser's session storage, so the opening animation plays once per visit instead of on every page. It is not a cookie, it carries no identity, and it is gone when you close the tab.

What is not stored

No analytics, no advertising, no tracking of any kind. The site works without any of this.

Switching it off

Your browser settings let you block or delete anything a site stores. The site keeps working; you may just see the opening animation again.
