Privacy policy
Your music stays between your watch and your server.
Cuff doesn’t collect personal data. There’s no Cuff account, no analytics, no ads and no tracking, and we don’t run any servers that the app talks to. This page explains what the app stores on your watch, which services it connects to, and why.
Who we are
Cuff is a Wear OS music player made by Thomas Johnsrud. Cuff is an unofficial app: it is not made, affiliated with or endorsed by Plex, Inc. If you have questions about this policy, email cuff.support@proton.me.
What Cuff stores on your watch
Everything below stays on your watch. None of it is sent to us.
- Your Plex sign-in token, so you stay signed in. It’s stored encrypted using the Android Keystore.
- A random installation ID that Plex requires to recognise the app. It isn’t linked to your name or email.
- Information about your music library (artists, albums, tracks and playlists) fetched from your Plex Media Server, so you can browse it on the watch.
- The music and cover art you download.
- Your settings and EQ profiles. Cuff keeps a separate EQ profile for each pair of headphones, identified by the headphones’ Bluetooth name and address.
Cuff excludes this data from Android backups. You can remove downloads at any time in Settings, and uninstalling Cuff (or clearing its storage) deletes all of it.
Services Cuff connects to
plex.tv
Cuff uses Plex’s official link-code sign-in: the watch shows a code that you enter at plex.tv/link. Cuff then asks plex.tv for the list of servers you can access. With these requests Cuff sends the installation ID, the app’s name and version, your watch’s model name and platform, and your Plex token. Plex, Inc. handles this under Plex’s privacy policy.
Your Plex Media Server
Cuff connects to the Plex Media Server you choose, to browse your library and download music. It sends the same identifying details as above. The owner of the server (you, or whoever shared it with you) can see in their Plex dashboard which device is connected and what it downloads, as with any Plex app. If the server owner has turned off downloads, Cuff doesn’t download from that server.
MusicBrainz and Cover Art Archive (optional)
Only if you turn it on: Cuff asks during setup, and you can change your answer in Settings. When an album on your server has no cover art, Cuff sends the artist and album name to MusicBrainz to find the album, then downloads the cover from the Cover Art Archive. Both are run by the MetaBrainz Foundation; see their privacy policy.
As with any internet connection, these services can see your IP address when Cuff connects to them. Cuff doesn’t connect to any other service.
Permissions
- Internet, network and Wi-Fi state: to reach your server, and to wait for Wi-Fi before downloading (the default).
- Nearby devices (Bluetooth): to read the name of the headphones you’ve connected, so Cuff can pick the right EQ profile. This stays on the watch.
- Notifications: to show what’s playing.
- Foreground service and wake lock: to keep music playing when the screen turns off.
What we don’t do
- We don’t collect, receive or store your personal data, listening history or library.
- Cuff has no analytics, crash reporting, advertising or tracking.
- We don’t sell or share data with anyone.
Children
Cuff isn’t directed at children under 13, and it doesn’t collect personal data from anyone.
