Cookies and similar storage
Last updated 28 October 2026
Cinebor uses a few small pieces of data stored in your browser. All of them are needed to make the service work or to remember a choice you made. We do not use advertising cookies, tracking cookies or third-party analytics, so there is no cookie banner to dismiss.
What we store
| Name | What it is for | Kind | How long |
|---|---|---|---|
| sb-…-auth-token | Keeps you signed in. It holds your sign-in session from our sign-in provider, Supabase (the name starts with sb- and may be split into numbered parts). | Cookie, essential | Until you sign out, or up to about 13 months. |
| cb_ref | Remembers a friend’s invite code from a link like /r/AB12CD34 until you finish signing up, so we can count the invite. Scripts on the page cannot read it. | Cookie, essential to the invite | 30 days. |
| cinebor-theme | Remembers whether you chose light or dark mode. | Browser storage | Until you clear it. |
| cinebor-adult-confirmed | Remembers on this device that you ticked “I am 18 or older”, so you do not tick it every time. | Browser storage | Until you clear it. |
| Offline page cache | The app saves one small offline page so it can show something when you have no connection. | Service worker cache | Until you clear it or we update it. |
| Notification subscription | If you turn on notifications, your browser creates an address that lets us reach this device. We store it so we can send them. | Browser feature | Until you turn notifications off. |
Other companies
We do not set cookies for other companies. Film posters load from the servers of The Movie Database (TMDB), so TMDB can see your IP address and browser details when a poster is shown. Fonts are served from our own site.
