Privacy

Last updated 29 October 2026.

Chunky is a music player for your Mac, made by Henry Black. It has no account, no advertising and no analytics. Your library, its tags, your playlists and your listening history stay on your Mac. This page says what leaves it, and when.

What Chunky sends

Checking for updates. Every few minutes Chunky asks releases.chunky.fm whether there is a newer version, and downloads it if there is. The request carries nothing about you, but, like any request on the internet, it shows your IP address to the server.

Looking up songs. When you use Look Up, Fill Gaps or Identify, Chunky sends what it knows about the songs you chose (title, artist, album, length, and an audio fingerprint when you identify a song by its sound) to the sources that answer: MusicBrainz, the Cover Art Archive, AcoustID, Deezer, and any source you add a key for, such as fanart.tv, Discogs or an AI tie-breaker. Each of them handles that request under its own privacy policy. Showing an artist, Chunky also asks Deezer (and fanart.tv, if you added a key) for that artist's picture by name, once per artist. Your source and metadata plugins can be turned off in Settings › Plugins.

Internet radio. When Radio is on, Chunky asks the crossfade.fm station directory for stations as you browse, and tells it which station you started and whether it played, so broken stations can be found and popular ones ranked. No account or identifier goes with it. Stations are streamed from the broadcasters' own servers, which see your IP address. Turn Radio off in Settings and Chunky makes no radio requests.

Your servers. If you add a Navidrome, Jellyfin or Plex server, Chunky talks to that server with the details you gave it. Your passwords and tokens are kept in the macOS Keychain. Plex sign-in goes through plex.tv.

Reporting a problem. Help › Report a Problem… sends a report only when you press Send. It holds what you wrote, any screenshots you added, Chunky's version, your macOS version and Chunky's text logs. Before anything is sent, Chunky blanks out every password, key and token it finds in the logs, and your home folder's name. The logs can still name songs, folders and servers. You see the whole report first and can take the logs or screenshots out. Reports go to Henry's own dashboard and are used only to fix Chunky.

What Chunky doesn't do

• It doesn't sell or share your data with anyone.
• It doesn't send what you play anywhere, apart from the radio report above. A server you added may keep its own play counts.
• It doesn't upload your music.

The waitlist

When you join the waitlist on chunky.fm, your email address and the date are kept so that Henry can send you the download link and news about the Chunky beta. They are used for nothing else, and they are never shared or sold. To check that a person, not a bot, is using the form, it uses Cloudflare Turnstile, which handles that check under Cloudflare's privacy policy. Your IP address is not stored with your email. To be taken off the list, write to privacy@chunky.fm and your address will be deleted.

Questions

Write to privacy@chunky.fm and you'll get an answer from Henry. To have a problem report deleted, give its ID, which Chunky showed when it was sent.
