Privacy Policy — effective 2026-10-23. English summary below each heading.

1. 我们收集哪些信息

刷题本身不需要账号。只有当你注册、登录或使用 AI 讲解时,我们才会处理以下数据:

未登录时,做题进度、错题本、笔记、语言与主题设置只保存在你自己的浏览器里(localStorage)。登录后,Class B 做题进度、错题与书签标记、笔记和学习天数会随账号同步到 Cloudflare D1,以便在其他浏览器继续学习。其他车型的进度和笔记、语言与主题设置、翻译与 AI 缓存仍只保存在本机。

When signed out, study progress, wrong-answer list, notes and preferences stay in your browser (localStorage). When signed in, Class B progress, wrong-answer and bookmark markers, notes and study days sync to Cloudflare D1 so you can continue in another browser. Other vehicle-class progress and notes, preferences, translation and AI caches stay on that device.

2. AI 讲解

只有你点击生成时,相关题目文本才会被送到我们的服务器,并转发给上游 AI 服务商(DeepSeek)用于生成讲解。生成结果缓存在你的浏览器中。我们不会用你的题目或问句做广告。

Question text is sent to our server and forwarded to the upstream AI provider (DeepSeek) only when you click to generate an explanation. Results are cached in your browser.

3. 支付

付费由 Stripe 处理。我们不接触、不存储你的银行卡信息;我们只会收到付款是否成功以及订单标识,用于自动解锁。Stripe 的隐私政策适用其自身的处理行为。

Payments are handled by Stripe. We never see or store card data — we only receive whether the payment succeeded and an order reference.

4. 数据存储与共享

账号与额度数据存放在 Cloudflare(Workers KV),登录用户的同步学习进度存放在 Cloudflare D1。我们不出售、不出租你的个人数据,也不用于广告投放。仅在以下情况共享:支付处理(Stripe)、AI 讲解生成(DeepSeek)、以及法律要求时。

Account and quota data are stored on Cloudflare (Workers KV); synced study progress for signed-in users is stored on Cloudflare D1. We never sell or rent your personal data, and we do not use it for advertising.

5. 保存期限与删除

账号数据在账号存在期间保存。你可以随时邮件联系我们删除账号及全部相关数据;删除后不可恢复。

You can request deletion of your account and all related data at any time by email; deletion is irreversible.

6. Cookie 与本地存储

本站不使用广告或跨站跟踪 Cookie。localStorage 用于保存本机学习进度、偏好设置以及翻译与 AI 缓存。

No advertising or cross-site tracking cookies. localStorage is used for on-device study progress, preferences, and translation and AI caches.

7. 未成年人

本站面向准备德国驾照理论考试的考生,不面向 16 岁以下儿童,也不会有意收集其数据。

The site is not directed at children under 16 and does not knowingly collect their data.
