WristSun calculates astronomical solar events locally on your watch. It has no account, backend, ads, analytics or location-upload service. Manual coordinates, IANA time zone, date selection and language are stored locally so the app can recover offline.
Location is optional and used only to select coordinates on this watch. You can refuse permission and enter a place manually. The app does not request background location or automatically log location history. On Apple Watch, explicitly saving a photo plan stores its chosen coordinates, time zone, date, complete golden-window timestamps and shooting/preparation minutes locally. One active plan is shown; a previous valid plan may be kept locally for recovery. Home changes do not retarget it, and it is not uploaded. Coordinates alone do not determine a time zone: verify the chosen zone yourself.
Remove the app to remove local settings and saved plans. Your device's own backup and operating-system services are controlled by its vendor. Times are estimates and do not predict cloud cover or actual illumination. See support for usage and limitations.

日光时刻在手表本地计算太阳事件，无账号、服务器、广告、分析统计或位置上传服务。手工坐标、IANA 时区、日期选择和语言保存在本地，以便离线恢复。
定位为可选项，仅用于在此手表上选择坐标。拒绝定位后仍可手工输入。本应用不请求后台定位，也不自动记录位置历史。在 Apple Watch 上显式保存拍摄计划，会在本地保存其坐标、时区、日期、完整黄金窗口瞬时及拍摄与准备分钟数。仅显示一份当前计划，可在本地保留一份旧有效计划用于恢复。首页修改不会改变该计划，也不会上传。坐标本身不确定时区，请核对所选时区。
删除应用会删除本地设置与拍摄计划。设备自带的备份及系统服务由设备厂商控制。时间为天文估算，不预测云量或实际光照。用法与限制见支持页面。
