Cookies

This site does not set cookies. The table below is the complete picture of what the public site and the RielOS workspace use.

Public site (rielincos.com)

• No cookies. Nothing is written to document.cookie by this website.
• One local preference. The “Save” control beside holUpp stores a flag in localStorage (rielos.site.saved.holupp) so your choice survives a refresh. It is not transmitted anywhere.

RielOS workspace (/app)

• Session cookie. A first-party, HttpOnly session cookie authenticates you after sign-in, so the server — not the browser — decides what you may see.
• CSRF token cookie. A second first-party cookie carries the anti-forgery token required on state-changing requests.
• Both are strictly necessary for the workspace to function. Clearing them signs you out.

Third parties

No advertising or analytics cookies are used, so there is no consent banner to dismiss and no profile to opt out of. Fonts and styles are served from this domain, not from third-party CDNs.
