Privacy Policy隐私政策

The short version: Piru does not collect, store, or transmit any of your personal data. Everything stays on your device.简短版：Piru 不收集、不存储、也不传输你的任何个人数据。一切都留在你的设备上。

Data storage数据存储

All data you enter into Piru — dose logs, substance preferences, daily-dose settings, and app settings — is stored exclusively on your device using Apple's on-device storage. It is shared only with Piru's own home-screen widgets and Lock Screen Live Activity. No data is sent to any external server, cloud service, or third party.你输入 Piru 的所有数据——剂量记录、物质偏好、每日服药设置以及应用设置——都仅通过 Apple 的本地存储保存在你的设备上，且只与 Piru 自己的主屏小组件和锁屏实时活动共享。任何数据都不会发送至外部服务器、云服务或第三方。

What we don't collect我们不收集的内容

• No personal information (name, email, phone number)不收集个人信息（姓名、邮箱、电话号码）
• No health or substance data不收集健康或物质使用数据
• No analytics or usage tracking不进行分析或使用追踪
• No automatic crash reporting不自动上报崩溃
• No advertising identifiers不使用广告标识符
• No location data不收集位置数据

Network requests网络请求

Piru's substance database is bundled inside the app and works fully offline. The app makes no network requests as part of normal use. The only optional network activity is a once-a-day check for a substance-database update: it downloads a verified data file and is verified before use. This check transmits nothing about you, your device, or anything you have logged, and it can be turned off.Piru 的物质数据库内置于 App 中，可完全离线运行。在正常使用中，App 不发起任何网络请求。唯一可选的网络活动，是每天一次检查物质数据库更新：它会下载一个经校验的数据文件并在使用前验证。该检查不会传输任何关于你、你的设备或你所记录内容的信息，并且可以关闭。

Data export & deletion数据导出与删除

You can export all your data at any time via Settings → Export Data, as a JSON file or a PDF report. The export is a local file that stays on your device unless you choose to share it. Deleting the app removes all stored data permanently — there is no backup or recovery mechanism, because no data exists outside your device.你可随时通过“设置 → 导出数据”导出全部数据，格式为 JSON 文件或 PDF 报告。导出的文件保存在本地，除非你主动分享，否则不会离开你的设备。删除 App 将永久移除所有存储的数据——不存在任何备份或恢复机制，因为设备之外不存在任何数据。

Changes to this policy本政策的变更
