开发者不收集 App 数据 / No developer data collection

Groove Lab 不需要帐号，没有广告、第三方分析 SDK、推送通知或跨 App 跟踪，不请求麦克风权限。开发者没有为练习数据设置上传服务器。
Groove Lab requires no account and includes no ads, third-party analytics SDKs, push notifications, cross-app tracking, or microphone permission. The developer does not operate a server that collects your practice data.

本机数据 / On-device data

速度、音层、音色、练习时长、语言和预备设置保存在设备上。早期版本的笔记与升级备份也仅保存在本机；主屏笔记入口已撤下。删除应用会移除其本机容器；备份与恢复由 Apple 和设备设置管理。
Tempo, layers, timbres, duration, language, and count-in settings are stored on-device. Legacy notes and migration backups also stay locally. Removing the app removes its local container; backups and restores are governed by Apple and your device settings.

系统分享与外链 / System sharing and links

你主动导出来源与许可时，App 生成本机临时文件并打开系统分享面板。只有你选定的目标会收到文件，目标按其自身政策处理。教学与来源链接在系统浏览器中打开，第三方网站按各自政策处理访问。
When you explicitly export source and license information, the app creates a local temporary file and opens the system share sheet. Your selected destination handles it under its own policy. Reference links open in the system browser, and third-party sites apply their own policies.

Apple 诊断 / Apple diagnostics

Apple 或操作系统可能根据你的诊断、分析、App Store 与设备设置处理崩溃或性能信息，这些系统服务受 Apple 政策约束。
Apple or the operating system may process diagnostics according to your App Store and device settings and Apple's policies.
