星星点灯 (the "App") is a private, on-device habit tracker. Your privacy is simple here: the App does not collect, transmit, sell, or share any personal data.
Nothing. The App has no account system, no login, and no analytics or tracking. It makes no network requests to send your data anywhere.
Everything you create — your habits ("rivers"), your check-ins ("stars"), settings, and the sky snapshots you save — is stored only on your device. It is included in your normal device backup (e.g. iCloud device backup) if you have one enabled, which is controlled by Apple and your own settings, not by us. Deleting the App removes this data.
If you turn on the nightly reminder, the App schedules a local notification on your device. This is handled entirely on-device and is never sent to any server.
When you choose to share a picture of your sky, it is handed to the system share sheet so you can save it or send it via an app you pick. The App itself does not upload it anywhere.
The App collects no data from anyone, including children.

星星点灯（"本应用"）是一款数据完全保存在本机的习惯打卡应用。隐私很简单： 本应用不收集、不上传、不出售、不分享任何个人数据。
不收集任何信息。本应用没有账号、没有登录、没有统计或追踪，也不会通过网络把你的数据发送到任何地方。
你创建的一切——你的习惯（"星河"）、打卡（"星星"）、设置，以及你保存的星空图片——都只存在你的设备本机。 如果你开启了系统备份（如 iCloud 设备备份），这些数据会随系统备份一并保存，这由 Apple 和你自己的设置控制，与我们无关。 删除应用即清除这些数据。
若你开启每晚提醒，本应用会在你的设备上安排一条本地通知。整个过程都在本机完成，不会发送到任何服务器。
当你选择分享星空图片时，图片会交给系统分享面板，由你决定保存或通过哪个应用发送。本应用本身不会上传它。
本应用不向任何人（包括儿童）收集数据。
如本政策有更新，最新版本将发布在本页面。
