Cookies and browser storage

Essential sign in cookie

CHUMA Archive sets __Host-archive-session after sign in. It contains a random session identifier, not your access key or project content. It is a first party cookie with Secure, HttpOnly and SameSite=Strict attributes and a maximum lifetime of 7 days. Signing out invalidates it and clears the cookie.

No advertising or analytics cookies

The application does not install advertising pixels, analytics cookies or third party embedded players. We do not use local storage for tracking. The necessary authentication cookie supports a service you explicitly request, so a consent banner is not used for it. If we add optional tracking, it will remain disabled until the required consent has been obtained.

Your controls

You can delete or block cookies in your browser. Blocking the authentication cookie prevents sign in. Infrastructure request processing and security metadata are explained in the privacy notice. Contact: chumastudiobyelena@gmail.com.
