Privacy Policy

CrabyTube does not collect, store, or share any personal data.

No account and no login. CrabyTube uses YouTube Music anonymously and stores no credentials or cookies.
No telemetry, analytics or crash reporting.
Network requests go only to the services needed for the features you use: YouTube Music, YouTube and Google servers (catalog, artwork, audio and the BotGuard challenge), and the lyrics services LRCLIB and Better Lyrics. Discord Rich Presence (off by default) talks only to the Discord client running on your computer.
On Windows and macOS, the update check (on by default, Settings → Updates) downloadsupdate.json and its signature from the latest release on GitHub once a day, and the new package when you choose to update. The requests carry the app's version in their user agent and nothing about you. The Flatpak makes no update requests.

LRCLIB (lrclib.net) receives the track's title and artist.
Better Lyrics (api.betterlyrics.org) receives the title, the artist and the duration when they are known, and the YouTube video ID; its QQ Music and Kugou lookups go through the same service.
Lyrics are requested when the Lyrics tab is open, and also during the last 30 seconds of a track for the next track in the queue. Fetched lyrics are cached on your computer for 30 days.

The track that plays and the next one are downloaded to a temporary folder in the cache directory while they play. Files left behind by a crash are removed when CrabyTube starts.
The CRABYTUBE_NETWORK_DIAGNOSTICS environment variable, meant for troubleshooting, makes the BotGuard helper send one request to api64.ipify.org each time it runs. It is off unless you set it.

The full and always up-to-date details live in theCrabyTube README.
