Jellystack

Jellystack is a privacy-focused Jellyfin and Seerr client with a native Android experience. Browse and play your own media, manage requests, download for offline use, and keep playback state in sync—without a Jellystack cloud, ads, analytics, or tracking.

Highlights

• Jellyfin libraries, favourites, watched state, progress, search, and Quick Connect
• Direct Play and HLS playback with audio, subtitle, and quality selection
• Offline downloads stored in app-specific storage
• Seerr discovery, requests, seasons, request status, trailers, and recommendations
• Cinematic details with cast, ratings, streams, collections, and similar titles
• Phone and tablet layouts, English and German, light and dark themes
• Contextual Cast permissions and an optional biometric app lock

Android is the stable, published platform. The shared Kotlin Multiplatform code and iOS host remain experimental; iOS is not currently distributed as a supported release.

Privacy

Jellystack connects directly to servers configured by the user. Server credentials and tokens are stored in the platform-protected credential store. The app has no analytics SDK, automatic log upload, advertising, or developer-operated media proxy.

See Privacy, Permissions, and the German privacy policy.
