产品构想The idea
每天晚上，用户在应用里「启航」，然后放下手机去睡觉。第二天早上打开应用，会看到这一夜航行的结果：走了多远、经过了什么、带回了什么。日复一日，这些夜晚汇成一张属于自己的航海日志。Each night the user sets sail in the app, then puts the phone down and goes to sleep. The next morning they open it to find out how the voyage went: how far they travelled, what they passed, and what they brought back. Night after night, those voyages accumulate into a logbook of their own.
这层叙事之下是一层真实的数据：睡眠时长、入睡与起床时间、规律性趋势，全部来自系统健康数据，按原样呈现。想看故事的人看故事，想看数据的人看数据，两层互不干扰。Underneath that narrative sits a layer of real data: sleep duration, bed and wake times, consistency trends, all drawn from the system's health store and presented as they are. Those who want the story get the story; those who want the numbers get the numbers. Neither layer interferes with the other.

按夜积累的记录与收藏，让坚持本身留下可以翻看、可以分享的痕迹。Records and collectibles that accumulate night by night, so that persistence itself leaves something to revisit and to share.

数据与权限Data and permissions
产品计划通过 Apple HealthKit 读取用户已授权的睡眠分析数据，并在部分场景下使用设备运动传感器辅助判断作息。所有此类数据默认在设备本地处理与保存，权限均需用户显式授权，且可随时在系统设置中撤回。详见The product plans to read sleep analysis data through Apple HealthKit with the user's authorisation, and to use device motion sensors in some scenarios to help infer sleep timing. All such data is processed and stored on the device by default; every permission requires explicit consent and can be withdrawn at any time in system settings. See our 隐私政策privacy policy。 for details.
