Miusiku isn't a fully offline app: two optional features reach out to a third-party service, only when you use them. Neither is a library shipped inside the app - see the Privacy Policy for exactly what data each one receives.
| Service | Used for |
|---|---|
| LRCLIB | Lyrics metadata lookup, shown on screen for personal viewing only. |
| Apple iTunes Search API | Cover art lookup, only when you ask the song editor to find one. |
