Privacy Policy

Last updated: August 28, 2026

Prism is a media browsing front end for a Plex Media Server you already own and run. It has no server, no backend, and no account system of its own.

What Prism collects

Nothing. The developer of Prism does not operate any server that Prism talks to, and does not receive, store, or have access to any of your data, credentials, or viewing activity.

What Prism sends, and to whom

Prism runs entirely on your device and talks directly to services you choose to connect it to, using credentials you provide:

  • Plex — your Plex sign-in and server/library data, to browse and play your own library. Required for the app to function.
  • TMDB — used to look up trailer info (a YouTube video id) for titles Plex doesn't already have a trailer for, using an API key built into the app itself, not one you provide.
  • YouTube — only when a trailer is found (via a Plex extra or the TMDB lookup above), its video is played back through YouTube's own embedded player. No API key or account of yours is involved in this.
  • OpenRouter (optional) — used only if you add your own OpenRouter API key, to generate AI-written themed rows (e.g. "Sci-Fi Comedies") from titles in your library.
  • OpenSubtitles (optional) — used only if you configure a subtitle provider, to search for and download subtitles.

Each of these is a direct connection from your device to that service's own servers, under that service's own terms and privacy policy. Prism does not proxy, log, or see any of this traffic — it simply makes the request on your behalf, the same way a browser would.

Where your credentials are stored

Your Plex token and any optional API keys/credentials are stored only on your device, encrypted at rest with a device-local encryption key that never leaves the device. They are never sent to the developer or to any server other than the service they're for.

Third-party privacy policies
