1. INFORMATION WE COLLECT
Rhythm Lab is a fully offline metronome application. We do not
collect, store, or transmit any personal information to external

are stored locally on your device and never leave it.
Types of data stored locally:
• Metronome settings (BPM, time signature, visual preferences)
• Practice session history (duration, date, favorites)
• User preferences (sound, vibration, visual settings)
This data is stored using Android SharedPreferences and remains
exclusively on your device.
──────────────────────────────────────────────────────────────

Your metronome settings, practice history, and preferences are
saved using SharedPreferences on your device. This data:
• Never leaves your device
• Is not transmitted over the internet
• Is not shared with any third parties
• Is not accessible to the developer
• Is protected by your device's security measures
──────────────────────────────────────────────────────────────
