What Daylumen accesses on your deviceDaylumen 在你设备上访问什么
Apple Health (HealthKit)Apple 健康（HealthKit）
With your permission, Daylumen reads health data such as activity, sleep, heart-rate measures, and related metrics to understand your patterns. It only reads — it never writes to or changes anything in Apple Health.
在你授权后，Daylumen 读取活动、睡眠、心率等健康数据来理解你的规律。它只读取，绝不写入或改动 Apple 健康里的任何内容。
Photos照片
With your permission, Daylumen reads recent photos on your device to understand the context of your days (for example, time spent outdoors, travel, or late nights). It extracts only general, de-identified context. Your original photos, faces, and location data are never copied, uploaded, or transmitted.
在你授权后，Daylumen 在你的设备上读取近期照片，用来理解你日子的上下文（例如户外时间、出行、熬夜）。它只提取概括性的、去标识化的上下文。你的原图、人脸和位置数据绝不会被复制、上传或传输。
Notifications通知
If you turn on the optional morning check-in, Daylumen schedules local notifications on your device. Their content is generated on-device and is not sent through any server.
如果你开启了可选的晨间陪伴，Daylumen 会在你的设备上安排本地通知。其内容在设备上生成，不经过任何服务器。
How your data is processed你的数据如何被处理
