Privacy Policy
Effective October 9, 2026
音乐神器 is provided by independent developer Shaolie Lin.
Data collection
音乐神器 requires no account or sign-in. Chord lookup, chord playback and the metronome run on your device. We do not collect, upload, sell or share personal data through the app. The app includes no advertising, tracking or third-party analytics SDKs.
Data on your device
Local storage remembers your language, chord selections, metronome parameters and practice preferences. 音乐神器 does not send these settings to the developer. On iOS, system backups may include these settings and are managed by Apple and your device settings. The Android version disables app auto-backup and device-transfer backup. Deleting the app removes its local data; restoring an iOS backup may restore preferences.
Permissions and audio
The app plays bundled audio, does not record audio and does not request microphone, camera, contacts or location access. Background audio lets a metronome you started continue when you switch apps or lock your device. You can pause it in the app. On Android, playback uses a media playback foreground service and system notification, a wake lock during playback and optional vibration feedback. The Android app does not request internet permission.
Support and external pages
If you choose to email support, we receive your email address and the content you provide, use it only to handle your request and retain it only as needed for that purpose. Please avoid unnecessary sensitive information. When you open a support or privacy webpage, your browser and the website host may process access logs such as IP addresses under their own policies. This is separate from the offline app features.
Children and updates
The app does not knowingly collect personal information from children. We will update this policy and its effective date if features or data practices change.
