隐私摘要
DS 心率不设账户、不含广告或分析 SDK，也没有开发者服务器。开发者不会从 App 收集、上传、出售或共享你的心率读数、相机画面、备注或其他个人数据。
相机
经你授权后，App 会在内存中分析后置相机画面的指尖颜色变化，以估算脉搏节奏。照片和视频不会被保存、上传或分享；测量结束后，相机处理立即停止。
本地记录
你选择保存的估算值、状态标签、日期时间和可选备注只保存在 App 的受保护本地容器中。记录文件已从本 App 的 iCloud 备份中排除，不会发送给开发者。
Apple 健康
Apple 健康同步完全可选。启用后，App 只会把你明确保存的心率估算值写入 Apple 健康；不会读取你已有的健康数据。你可随时在系统设置或“健康”App 中撤销权限或删除相应样本。Apple 健康的数据存储与同步由 Apple 和你的设备设置管理。
设备端洞察与提醒
在支持的设备上，可选趋势洞察由 Apple 的设备端模型处理。每日提醒使用本地通知。这些功能不会把读数发送给开发者。
导出与分享
只有在你主动选择 CSV 导出或系统分享操作时，数据才会交给你选择的目标。离开 App 后，文件或文字由该目标的隐私政策管理。
保留、删除与安全
本地记录会保留到你删除单条记录、选择“删除全部读数”，或移除 App 及其数据为止。App 使用 iOS 提供的应用沙盒和数据保护机制。删除本地记录不会自动删除已写入 Apple 健康的样本。
儿童隐私
本 App 不以儿童为特定目标，也不会从任何用户收集个人数据。家长或监护人应根据实际情况指导未成年人使用一般健康工具。
医疗限制
DS 心率不是医疗器械。相机估算未经受监管医疗设备临床验证，不应被用于诊断、治疗、紧急情况或延误就医。移动、手指温度、按压力度、血流灌注、光线和相机硬件均可能影响结果。

Privacy Policy (English)
DS Heart Rate has no account system, advertising, analytics SDK, or developer-operated server. The developer does not collect, upload, sell, or share your heart-rate readings, camera frames, notes, or other personal data.
Camera processing
With permission, rear-camera frames are analyzed only in memory to estimate pulse timing from fingertip color changes. Photos and video are never saved, uploaded, or shared, and camera processing stops when the measurement ends.
Local records
Readings you save, context tags, timestamps, and optional notes remain in the app's protected local container. The record file is excluded from this app's iCloud backup and is not sent to the developer.
Apple Health
Apple Health integration is optional. When enabled, the app writes only heart-rate estimates you explicitly save and does not read your existing Health data. You can revoke access or delete samples in system settings or the Health app. Apple controls Health data storage and synchronization according to your device settings.
On-device insights, reminders, and sharing
Optional insights use Apple's on-device model on supported devices, and reminders are local notifications. Data leaves the app only when you deliberately export CSV or use the system share sheet; the selected destination then governs that data.
Retention and deletion
Local records remain until you delete an individual reading, choose Delete All Readings, or remove the app and its data. Deleting local records does not delete samples already written to Apple Health.
Children and medical limitation
The app is not directed specifically to children and does not collect personal data. DS Heart Rate is a general wellness tool, not a medical device. Camera estimates are not clinically validated against a regulated medical device and must not be used for diagnosis, treatment, emergencies, or to delay care.
