Necessary storage
The site may use session storage or cookies for form security, authenticated access, preferences and essential operation.
First-visit film preference
The homepage records that the introductory circadian-rhythms film has already been shown automatically. The primary marker is stored in first-party browser local storage until the visitor clears site data; a first-party cookie may be used as a fallback for up to 12 months. The marker contains no name, email address or health information and is used only to prevent repeat autoplay.
Consent preference
The public build stores a local preference for necessary-only or future analytics consent. No third-party analytics is bundled by default.
Future analytics
Any analytics, advertising or personalization tools added later should be loaded only through a consent-aware implementation where required.
Managing choices
Visitors can clear site storage in their browser. A full preference center should be added before optional technologies are introduced.
Portal cookies
Authenticated portals will require secure session cookies and may use multi-factor authentication and security logs.
Review
This policy must be updated when the production stack, vendors or legal requirements change.
