XLIIs — Privacy Policy

Effective: March 5, 2026

What XLIIs Does

XLIIs is a free music player for streaming freely available Grateful Dead live recordings from the Internet Archive (archive.org).

Data We Collect

XLIIs does not collect, store, or transmit any personal data. There are no accounts, no sign-ups, and no tracking.

Local Storage

The app stores your listening history, favorites, and playback position locally on your device using standard browser storage (localStorage).

Playback Sync

To let you resume listening across sessions, the app automatically saves your current playback position to a cloud database (Supabase). This data is anonymous — it is identified only by a randomly generated device ID, not tied to any personal information. No account or sign-in is required.

Network Requests

The app makes requests to archive.org to stream audio files and retrieve show metadata. No personal information is sent in these requests.

Third-Party Services

XLIIs does not use any analytics, advertising, or third-party tracking services.

Children's Privacy

XLIIs does not knowingly collect any information from children under 13.
