隐私政策
1. 我们不收集哪些信息
本应用不会收集任何个人身份信息。使用本应用无需注册账号、无需登录、无需填写姓名、手机号、邮箱或任何联系方式。我们不会读取你的通讯录、相册、位置、设备标识符或其他隐私数据，也没有集成任何广告、统计、分析或用户行为追踪的第三方 SDK。
2. 应用会在哪里保存数据
为了实现练习功能，本应用会在你的设备上保存以下内容：
- 练习进度与通关记录；
- 错题本记录；
- 牌面样式、主题等偏好设置；
- 是否已购买「终身会员」的解锁状态。
这些数据仅保存在你本机的应用存储空间，并（在你登录 iCloud 且开启同步时）保存到你自己的 iCloud 私有存储空间，用于在你的多台设备之间自动同步。iCloud 中的数据由 Apple 管理并归你所有，开发者无法访问、读取或获取这些内容。
卸载应用即会删除本机数据；iCloud 中的同步数据可在系统「设置 → Apple 账户 → iCloud」中管理和清除。
3. 购买与支付
本应用的「终身会员」通过 Apple App Store 内购完成。所有支付流程均由 Apple 处理并受 Apple 隐私政策约束，开发者不会接触到你的支付卡号、Apple 账户密码等任何支付信息，仅能从系统收到「该交易是否成功」的结果，用于在本机解锁相应内容。
4. 数据共享与第三方
我们不会将你的任何数据出售、出租或分享给任何第三方，因为本应用根本不收集这些数据。应用运行不依赖任何自建服务器。
5. 儿童隐私
本应用不收集任何个人信息，因此不会收集任何来自儿童的信息，适合各年龄段用户使用。
6. 政策更新
如本政策发生变更，我们会在本页面更新内容并修改上方的「生效日期」。重大变更会通过应用更新说明或本页面公示。

Privacy Policy
1. Information We Do Not Collect
This app does not collect any personally identifiable information. No account, sign-in, name, phone number, email, or contact details are required to use it. We do not access your contacts, photos, location, device identifiers, or any other private data, and we do not integrate any third-party advertising, analytics, or user-tracking SDKs.
2. Where Your Data Is Stored
To provide its training features, the app stores the following on your device:
- practice progress and level records;
- your mistake ("wrong answers") history;
- preferences such as tile style and theme;
- your "lifetime membership" unlock status.
This data is kept only in the app's on-device storage and, when you are signed in to iCloud with sync enabled, in your own private iCloud storage so it can sync automatically across your devices. iCloud data is managed by Apple and belongs to you; the developer cannot access, read, or retrieve it.
Deleting the app removes the on-device data. iCloud-synced data can be managed or cleared under Settings → Apple Account → iCloud.
3. Purchases and Payments
The "lifetime membership" is sold through Apple App Store in-app purchase. All payment processing is handled by Apple and governed by the Apple Privacy Policy. The developer never receives your card number, Apple Account password, or any payment details — only a success/failure result from the system, used to unlock content on your device.
4. Data Sharing and Third Parties
We do not sell, rent, or share any of your data with any third party, because the app does not collect such data in the first place. The app does not rely on any developer-operated server.
5. Children's Privacy
The app collects no personal information and therefore collects no information from children. It is suitable for users of all ages.
6. Changes to This Policy
If this policy changes, we will update this page and revise the "Effective date" above. Material changes will be noted in the app's release notes or on this page.
