This site is a set of static pages. There is no account, no form, no database, and nothing to fill in anywhere.
What does not exist here
No analytics, no advertising tracker, no cookie, no social button, no third-party script. The security policy the site sends with every page allows its own scripts only, which makes quietly adding a tracker impossible.
What stays in your browser
One setting is remembered: the light or dark theme, under the key aubaine.theme. Your browser writes it, it stays there, and it is sent nowhere. Clearing it is enough to forget it.
Hosting
The pages are served by Cloudflare, which handles the requests needed to deliver the files as any web server does. Aubaine adds no collection on top, and receives no data about you.
