简短版本

OCTAVE 不收集你的数据，也不向开发者或任何第三方发送数据。设置和练习记录只保存在你的 iPhone 上。App 不联网，没有账号，没有数据统计，没有广告，没有第三方代码。

麦克风

调音、长音、音域、声音可视化和 TAP 拍手测速会使用麦克风。声音只在你的 iPhone 上实时分析，分析完立即丢弃，不会录音，也不会发送到任何地方。你可以随时在 iPhone 设置 › OCTAVE 中关闭麦克风权限，不需要麦克风的工具照常可用。

保存在本机的内容

你的设置（例如标准音 A4、拍号、音色）和练习记录（例如音域、长音成绩）只保存在这台 iPhone 上。删除 App 即全部删除。

In short

OCTAVE does not collect your data and sends nothing to the developer or any third party. Your settings and practice history stay on your iPhone. The app makes no network connections and has no account, analytics, ads or third-party code.

Microphone

TUNE, HOLD, RANGE, SCOPE and TAP clapping use the microphone. Sound is analysed in real time on your iPhone and discarded immediately; it is never recorded or sent anywhere. You can turn microphone access off at any time in iPhone Settings › OCTAVE; tools that don't need it keep working.

What stays on your device

Your settings (for example reference A4, meter, sounds) and practice records (for example your range and HOLD scores) are stored only on this iPhone. Deleting the app deletes them.
