## What is Trackback Music?

Trackback Music watches your Apple Music library and playlists—so you notice when songs disappear, get removed, or turn gray (unavailable).

WHAT YOU GET
• Starting snapshot of your library on day one
• Currently unavailable inventory (songs already grayed out)
• Change history: removed, unavailable, added
• Protected playlists you choose to watch
• Manual scan anytime; Premium unlocks ongoing library rescans and daily auto-scan

WHY IT HELPS
Apple Music catalogs change. Tracks leave playlists, lose availability, or vanish from your library. Trackback Music keeps a local baseline and highlights what changed—on your device.

FREE VS PREMIUM
• Free: first library snapshot, currently unavailable list, up to 3 protected playlists, recent change history
• Premium: unlimited playlists, ongoing full-library monitoring, daily automatic scans, full history

Privacy-first: music data stays on your device. We don’t upload your library to our servers.
