Tonarr connects only to services you choose, such as Plex, Jellyfin, or OpenSubsonic/Navidrome. Those services may return account identity, library metadata, artwork, lyrics, playback URLs, playlists, ratings, and play history needed for features you use.
When you start content-label verification, Tonarr sends the selected tracks' artist, song, album, duration, and available public recording identifiers directly to Apple and Deezer so their public catalogues can return advisory clean or explicit metadata. Tonarr does not send audio, file paths, server addresses, credentials, listening history, account or device identifiers, or advertising identifiers with those lookups.
Discover retrieves public charts and recording metadata from Apple Marketing Tools, MusicBrainz, ListenBrainz, and Cover Art Archive. Private Daily Mixes and taste ranking run on your device. Artist-based discoveries are optional and off by default: enabling them sends up to three artist names selected from your local taste to MusicBrainz and ListenBrainz, and public recording identifiers to ListenBrainz for metadata. No listening events, account identity, server address, credentials, file paths, or audio accompany those requests. Turning sharing off cancels the refresh and removes the related recommendation cache on that device.
Optional music requests connect directly to the DroppedNeedle, Tonarr Connector, or Lidarr service the listener configures. Tonarr provides no media catalogue or acquisition sources itself. The selected service controls approval, availability, processing, and request retention. Request features depend on the platform and build you use; they remain separate from your playable media library.
