隐私政策

生效日期 Effective date：2026-11-07

一句话：《AI 百科全书》不收集任何个人数据。没有账号，没有服务器，没有广告，没有数据分析或追踪，也不含任何第三方 SDK。

In short: The AI Encyclopedia collects no personal data. No accounts, no servers, no ads, no analytics or tracking, and no third-party SDKs.

保存在你设备上的数据 Data on your device

你的阅读进度、书签、高亮、笔记、练习和术语卡记录、小测、互动题、情景模拟和实验记录，以及语言和阅读设置，只保存在你自己的设备上，不会上传。删除 App，或在「我的 → 设置 → 数据 → 重置学习进度」里重置，这些数据就会被删除。

Your reading progress, bookmarks, highlights, notes, exercise and flashcard records, quizzes, drills, scenarios and lab records, and your language and reader settings are stored only on your device and are never uploaded. Deleting the app, or using Me → Settings → Data → Reset progress, removes them.

购买 Purchases

「完整版」通过 Apple App Store 购买，付款由 Apple 处理。我们收不到你的姓名、邮箱、Apple 账户或任何付款信息；App 只向 Apple 查询「是否已购买」，用来解锁内容。

The Full Book is purchased through the Apple App Store and payment is handled by Apple. We never receive your name, email, Apple Account or payment details; the app only asks Apple whether the purchase exists in order to unlock content.

「用大白话解释」、搜索与导出 Explain simply, search and export

「用大白话解释」和部分实验里的写作示例使用设备上的 Apple 智能模型，在本机生成，你选中的文字不会发送给我们，也不会发送到任何服务器。
全书搜索在本机进行。
只有你主动「导出学习数据」时才会生成文件，存到你自己选择的位置。

"Explain simply" and the writing examples in some labs use Apple's on-device model; text you select is processed on your device and is never sent to us or to any server.
Search runs on the device.
An export file is created only when you choose Export learning data, and saved where you choose.

网络 Network

全书内容都打包在 App 里，阅读和实验都不需要联网。只有 App Store 购买 / 恢复购买会由系统联网完成；你点开的外部链接（比如本页）由浏览器打开。

All content is bundled in the app; reading and the labs work offline. Only App Store purchases and restores use the network, through Apple's system services; external links you tap (like this page) open in your browser.

儿童 Children

本 App 不收集任何人的个人信息，包括儿童。

The app collects no personal information from anyone, including children.
