Stopptanz

Stopptanz plays a local music file or playlist and randomly stops playback to drive a stop-dance party game (Freeze Dance / Musical Chairs). It's a music/timer engine only — no player, chair, or score tracking.

Features:
- Freeze Dance mode: music stops at a random point, then auto-resumes after a fixed pause (host can also resume early)
- Musical Chairs mode: music stops at a random point and stays stopped until the host resumes it manually
- Configurable stop-interval range per mode
- Playlist shuffle/loop
- Seek/skip controls
- System media notification controls

No ads, no analytics, no tracking, no network access at all. Music files are read only from local storage locations you pick yourself.
