CloudMusicBox (the “App”) is a Progressive Web Application that lets you stream
and temporarily cache for offline playback the audio files you store in your own
cloud-storage accounts—currently Google Drive and Microsoft OneDrive. We never
collect, transmit, or monetise personal data beyond what is strictly necessary
to provide this functionality.
===
# 1. What data we access
| Category | Details | Where stored |
|----------|---------|---------|
| OAuth credentials | Short-lived access tokens & refresh tokens returned by Google Drive / OneDrive sign-in \
| Browser-side storage (IndexedDB / sessionStorage). Never leaves your device. |
| File metadata | File ID, name, MIME-type, size, thumbnail link, last-modified time \
| Memory only; optionally mirrored in IndexedDB for fast library loading. |
| Audio content | File bytes requested via providers’ APIs \
| Streamed to the <audio> element and optionally cached locally for offline listening. Evicted automatically when browser quota is exceeded. |
We do not access contacts, photos, analytics identifiers, or any other personal data.
# 2. How we use the data
* List audio files, build your in-app library, and fetch album artwork colours for UI theming.
* Stream or play cached files—even when the device is offline.
* Refresh tokens silently so you don’t have to log in each time.
None of this information is transmitted to CloudMusicBox servers (there are none); all processing happens in the browser.
# 4. Sharing & disclosure
We share nothing with third parties.
File data moves only between your browser and the official Google Drive / OneDrive REST endpoints over TLS.
