1. What this notice covers
This notice explains how Nova Content OS uses cookies and similar browser storage. It should be read with our Privacy Policy. A cookie is a small value a website asks a browser to store; similar technologies include local storage, service-worker caches and push-subscription storage.
2. Strictly necessary storage
| Storage | Purpose | Typical duration |
|---|---|---|
nova_session | Opaque, Secure and HttpOnly application-session cookie. It authenticates requests without exposing Firebase or provider tokens to browser code. | Rotated during use; expires after 12 hours idle or 14 days absolute, and is cleared on logout. |
| Firebase in-memory authentication state | Completes registration, sign-in, reauthentication and verified identity changes. Nova configures this state not to persist across a browser refresh. | Current page session. |
nova-sidebar-collapsed | Remembers your preferred workspace sidebar width. | Until you change it or clear browser storage. |
nova-content-filters | Remembers your own workspace filter selections on that device. It is removed on logout and account deletion. | Until logout, deletion or browser-storage clearing. |
| Offline shell cache | Stores the offline screen, application mark and manifest so a helpful offline state can load. It does not cache private workspace pages or API responses. | Until the cache is replaced by an updated version or browser storage is cleared. |
| Web-push subscription | Used only if you opt in to browser reminder notifications. | Until you disable the channel, revoke browser permission or delete the account. |
3. No advertising or analytics cookies
Nova currently does not set advertising, cross-site tracking or optional audience-analytics cookies. Because the storage listed above is necessary to provide requested security, preferences, offline handling or notifications, we inform you about it without presenting a misleading consent banner. If we introduce non-essential storage, it will remain off until the required choice is available.
Nova does not store Google or YouTube browser-session cookies. Choosing a YouTube connection sends you to Google's own OAuth pages, where Google and YouTube may use cookies or similar technology under the Google Privacy Policy.
4. Your controls
Browser settings let you inspect or clear cookies, site data, service workers and notification permissions. Blocking the session cookie prevents access to the authenticated workspace. Clearing preference storage resets the relevant interface choice but does not delete your server-side workspace. Use Nova's Account page for logout or account deletion and Advanced for a workspace export.
