隐私政策Privacy Policy

生效日期：2026-07-30 · 适用于 Lumo（流墨）macOS 应用 Effective 2026-07-30 · Applies to the Lumo app for macOS

一句话版本：Lumo 不收集任何数据。应用完全离线运行，不申请网络权限——你的文档、批注和阅读记录从不离开你的电脑。 The short version: Lumo collects no data at all. The app runs fully offline and requests no network access — your documents, annotations and reading history never leave your Mac.

我们收集什么What we collect

什么都不收集。Lumo 没有账号系统、没有分析统计、没有崩溃上报、没有广告标识符，也不包含任何第三方 SDK。应用本体不具备联网能力（不申请 macOS 网络权限）。 Nothing. Lumo has no accounts, no analytics, no crash reporting, no advertising identifiers, and no third-party SDKs. The app itself has no networking capability (it requests no macOS network entitlement).

你的数据存在哪里Where your data lives

你的文档：始终留在你的电脑上。批注、签名、表单内容直接写入你自己的 PDF 文件。 Your documents stay on your Mac. Annotations, signatures and form entries are written into your own PDF files.
阅读偏好（每份文件的阅读位置、主题、书签、最近文件列表等）：仅保存在本机的应用沙盒容器中，随应用卸载而删除。 Reading preferences (per-file position, themes, bookmarks, recent files) are stored only in the app's local sandbox container and are removed when you delete the app.

App Store 版本的购买Purchases on the App Store version

「Lumo Pro」内购与恢复购买由 Apple 的 StoreKit 在系统层完成。我们不会收到你的姓名、支付方式或任何账户信息；交易由 Apple 依其隐私政策处理。 The “Lumo Pro” purchase and restore flows are handled by Apple's StoreKit at the system level. We never receive your name, payment details or account information; transactions are processed by Apple under its own privacy policy.

官网直装（DMG）版本Direct-download (DMG) version

与 App Store 版一样完全离线。应用没有自动更新组件——了解新版本的唯一方式是你主动访问本网站。 Fully offline, same as the App Store build. There is no auto-update component — the only way the app "phones home" is you visiting this website yourself.
