Screen Time permission

Sundial reads your usage and blocks apps through Apple's Screen Time framework. Without that permission the app can show nothing and limit nothing. If you declined it, or revoked it later, turn it back on in Settings → Screen Time → Sundial.

晷通过 Apple 的「屏幕时间」框架读取用量并屏蔽 App。没有该权限，App 无法显示数据也无法限制。如果曾拒绝或撤销，请在设置 → 屏幕时间 → 晷中重新开启。

Why does the widget show more time than I actually used?

If Share Across Devices is on, Apple includes usage from other devices signed in to the same Apple ID — a Mac, for example — in the activity Sundial's monitor receives, and Apple gives apps no way to scope that to one device. The daily report inside the app is limited to this iPhone. To make the two agree, turn Share Across Devices off in Settings → Screen Time.

如果开启了「跨设备共享」，Apple 会把同一 Apple ID 下其它设备（例如 Mac）的用量也算进晷后台收到的数据里，而 Apple 没有给 App 按设备筛选这些事件的能力。App 内的日报只统计这台 iPhone。想让两者一致，请在 设置 → 屏幕时间中关闭「跨设备共享」。

What happens when a limit runs out?

iOS shields the apps in that rule. The shield shows what you finished and the reason you set for the rule, and offers three ways on: I'm Done (keeps the limit), 15 more minutes, or Remove Limit for the rest of the day. Limits reset at midnight.

到时间点，该规则里的 App 会被系统屏蔽。屏蔽页会显示你今天完成了多少、以及你为该规则设定的理由，并给出三个出口：今天到此为止（保留限额）、再玩一刻钟、或今天解除限制。限额在每天 00:00 重置。

Purchases

Sundial Pro is a one-time purchase, not a subscription — there is nothing to cancel. If Pro does not appear after buying or restoring, open Settings → Sundial Pro → Restore Purchase. Purchases are tied to your Apple ID; billing is handled by Apple.

晷 Pro 是一次性买断，不是订阅，因此无需取消。若购买或恢复后没有解锁，请打开 设置 → 晷 Pro → 恢复购买。购买与 Apple ID 绑定，由 Apple 处理账单。

My data

Usage, limits and settings live only on your iPhone — there is no account and no server. Deleting the app removes them; removing individual limits or changing the theme does too. See the Privacy Policy.

用量、限额与设置只保存在你的 iPhone 上，没有账号也没有服务器。删除 App 即可清除这些数据，删除单条限额或更换主题同理。详见隐私政策。

Requirements

iPhone with iOS 27 or later. Sundial is iPhone-only; it does not run on iPad, and it does not track other devices or people.
