本政策适用于 TianDev Studio 提供的 Metronome 应用。This policy applies to the Metronome app provided by TianDev Studio.
节拍速度、拍号、音色、训练历史与应用设置保存在设备本地。启用闪光同步时，应用仅为控制手电筒请求相机权限，不会拍摄或保存照片。Tempo, time-signature, sound, training-history, and preference data are stored locally. Camera permission is requested only to control the torch for flash sync; the app does not take or retain photos.
应用可使用 Google AdMob 提供广告、RevenueCat 处理购买状态，并使用分析服务了解功能使用情况。这些服务可能根据其各自政策处理设备标识符、购买信息、诊断与使用数据。在 iOS 上，需要跟踪时会先请求您授权。The app may use Google AdMob for ads, RevenueCat for purchase status, and analytics services. These providers may process device identifiers, purchase information, diagnostics, and usage data under their own policies. On iOS, tracking permission is requested before tracking where required.
购买由 Apple 处理；我们不会获取完整支付卡信息。Payments are processed by Apple; we do not receive full payment-card details.
您可以在 iOS 设置中更改跟踪、相机与其他权限，并可通过删除应用清除本地数据。You can change tracking, camera, and other permissions in iOS Settings and remove local data by deleting the app.
我们不会故意收集 13 岁以下儿童的个人信息。We do not knowingly collect personal information from children under 13.
