Summary / 摘要

Guitar Cue has no account, advertising, tracking, analytics, or developer-operated cloud service. The developer does not collect personal data through the app.

Guitar Cue 不需要账号，不含广告、跟踪、分析或开发者云服务。开发者不会通过本 App 收集个人数据。

Microphone / 麦克风

With your permission, Guitar Cue processes microphone audio in memory to identify single guitar notes for tuning, training, and exams. Raw audio is not recorded to a file, saved, or uploaded. Microphone capture stops when the app leaves the foreground. If you explicitly start the metronome, its audio output may continue in the background; this does not enable background microphone capture.

经你授权后，Guitar Cue 会在内存中实时处理麦克风音频，用于调音、训练和测验。原始音频不会录音、保存或上传；App 离开前台时会停止麦克风采集。用户主动启动的节拍器可以在后台继续输出声音，但不会因此启用后台麦克风。

Data on your devices / 本地数据

Settings, practice progress, results, and a cached purchase-entitlement state are stored locally on your iPhone or Apple Watch. You can reset settings and practice data in the app or delete the app to remove its local container.

Apple services / Apple 服务

StoreKit sends purchase and restore requests to Apple. WatchConnectivity transfers language, entitlement, tempo, prompt, command, and result state between your paired iPhone and Apple Watch; it never transfers raw microphone audio. Apple processes information under its own privacy policy.
