隐私政策
生效日期：2026 年 9 月 29 日
VocabLoop（“本 App”）由个人开发者开发和运营（“我们”）。简单说：我们不收集你的个人信息。你在本 App 里的一切都只保存在你自己的设备上。
1. 保存在你设备上的数据
- 学习数据：你学习的单词、复习记录、每日目标、设置。
- 账户（可选）：如果你创建账户，邮箱和显示名称保存在设备上；密码不会被保存，只保存经 PBKDF2 加盐哈希后的结果；登录状态保存在 iOS 钥匙串中。
这些数据不会上传到我们的服务器——我们没有服务器。它们不会被出售、共享或用于广告。不创建账户（游客模式）也可以使用全部学习功能。
2. 第三方登录
- 通过 Apple 登录：Apple 会向本 App 提供一个匿名用户标识，首次登录时可能提供你的名字和邮箱（可以是 Apple 的隐藏邮箱）。这些信息只保存在你的设备上。受 Apple 隐私政策约束。
- 通过 Google 登录：登录在 Google 的网页上完成。Google 向本 App 提供你的 Google 账号标识、名字和经过验证的邮箱。这些信息只保存在你的设备上。受 Google 隐私政策约束。
3. 购买
VocabLoop Plus 通过 Apple App Store 购买。付款由 Apple 处理，我们收不到你的付款信息，只从 Apple 获得“是否已购买”的确认。
4. 其他
- 单词发音由 iOS 系统在设备上生成，不联网。
- 学习提醒是设备上的本地通知。
- 本 App 不包含广告、统计分析或追踪工具，不使用任何第三方 SDK，不追踪你在其他 App 或网站上的活动。
5. 儿童隐私
本 App 适合所有年龄。因为我们不收集任何个人信息，所以也不会收集儿童的个人信息。家长可以用 iOS“屏幕使用时间”管理 App 内购买。
6. 你的权利
你可以随时在“设置 → 账户”导出数据（Export my data）或删除账户（Delete account）。删除 App 会删除设备上的全部数据。
7. 政策变更与联系方式
政策如有变更，会更新本页并修改生效日期。有任何问题，请联系 vsv.zhang@gmail.com。
Privacy Policy
Effective 29 September 2026
VocabLoop (“the app”) is made by an independent developer (“we”). In short: we do not collect your personal information. Everything you do in the app stays on your device.
1. Data stored on your device
- Study data: the words you study, your review history, daily goal and settings.
- Account (optional): if you create an account, your email and display name are stored on the device. Your password is never stored — only a salted PBKDF2 hash. Your sign-in session is kept in the iOS Keychain.
This data is not uploaded to us — we do not run a server. It is never sold, shared or used for advertising. Every study feature works without an account.
2. Signing in with Apple or Google
- Sign in with Apple gives the app an anonymous user identifier and, the first time only, your name and email (which may be a private relay address). They are stored on your device only. See Apple’s Privacy Policy.
- Sign in with Google happens on Google’s own page. Google gives the app your Google account identifier, name and verified email, which are stored on your device only. See Google’s Privacy Policy.
3. Purchases
VocabLoop Plus is sold through the Apple App Store. Apple processes the payment; we never see your payment details and only receive confirmation that the purchase was made.
4. Everything else
- Pronunciation is generated on your device by iOS, offline.
- Study reminders are local notifications scheduled on your device.
- The app contains no advertising, analytics or tracking, uses no third-party SDKs, and does not track you across other apps or websites.
5. Children
The app is suitable for all ages. Because we collect no personal information, we collect none from children. Parents can manage in-app purchases with Screen Time.
6. Your choices
You can export your data (Settings ▸ Account ▸ Export my data) or delete your account (Settings ▸ Account ▸ Delete account) at any time. Deleting the app deletes all of its data from your device.
7. Changes and contact
If this policy changes, this page and its effective date will be updated. Questions: vsv.zhang@gmail.com.
