隐私政策
生效日期:2026-06-15 · 适用应用:Vista(iOS)
1. 我们的核心立场
Vista 在设计之初就坚持「隐私优先」:
- 无账号、无登录、无注册——使用 Vista 不需要提供姓名、手机号、邮箱等任何身份信息。
- 无开发者服务器——App 不向开发者的任何服务器收集或传输数据。
- 无第三方 SDK——没有分析(Analytics)、没有广告、没有崩溃上报、没有追踪,也不集成 Firebase、Sentry 或任何第三方服务。
- 开发者无法访问您的数据——我们没有服务器来接收数据,因此即便我们想,也无从获取。
2. 我们收集哪些数据
我们不收集任何个人数据。包括但不限于:姓名、邮箱、电话、位置、设备标识符、广告标识符、通讯录、相册、使用行为等——一概不收集。
3. 您的数据存储在哪里
您使用 Vista 过程中产生的所有数据,默认仅保存在本地设备上(通过设备内置的本地数据库存储),包括:
- 学习进度与复习记录
- 积分账本(流水)、会话与成就
- 连续学习天数、词汇掌握度等派生统计
- 应用设置(主题、明暗模式、语言等)
这些数据默认仅保存在本地设备,从不上传到开发者或任何第三方服务器。卸载 App 会删除本地数据。
4. iCloud 同步
若您已登录 iCloud,Vista 可使用 Apple 的 CloudKit 私有数据库在您的多台设备间同步学习数据。这些数据存储于您本人的私有 iCloud 账户、由 Apple 加密管理,开发者没有服务器、无法读取或访问。同步是可选的,您可随时在 iOS「设置」›「Apple ID」›「iCloud」中关闭;关闭后数据仅保存在本地设备。
5. 内购与支付
Vista 提供一次性买断「Vista Pro」内购(商品标识:com.bytelink.vista.pro)。该交易完全由 Apple 通过 App Store 与 StoreKit 处理。
- 它是一次性买断,不是订阅、不会自动续费。
- 我们不接触、不收集、也不存储您的任何支付信息(如银行卡号、Apple ID 等)。
- 购买凭证的校验由 Apple 处理或在设备本地完成;您可在登录相同 Apple ID 的设备上「恢复购买」。
- 退款请求依据 Apple 的退款政策处理。
6. 本地通知
若您开启学习提醒,相关通知由您的设备本地调度与发送,不经过任何服务器。您可随时在系统「设置」中关闭通知权限。
7. 我们「不」收集的内容
Vista 不含任何第三方分析 SDK、广告 SDK,也无任何追踪。我们不收集您的通讯录、位置、照片、麦克风或浏览行为,也不向任何第三方出售或共享数据。
8. 适用人群与儿童隐私
Vista 面向大众用户,不在知情情况下收集儿童个人信息。由于本 App 不收集任何用户的任何个人数据,因此对各年龄段学习者均安全。
9. 您的权利与数据删除
您完全掌控自己的数据。可随时在应用内「设置 › 清除所有数据」抹除全部本地学习数据。删除应用将移除所有设备本地数据。如需移除已同步数据,请为 Vista 关闭 iCloud,或在 iCloud 设置中删除该应用的数据。
10. 政策变更
我们可能不时更新本隐私政策。任何变更将更新本页上方的「生效日期」;重大变更我们会尽量在应用内提示。

Privacy Policy
Effective Date: 2026-06-15 · Applies to: Vista (iOS)
1. Our Core Position
Vista was built privacy-first from day one:
- No account, no login, no registration — using Vista requires no name, phone number, email, or any identity information.
- No developer servers — the app collects or transmits no data to any developer server.
- No third-party SDKs — no analytics, no ads, no crash reporting, no tracking, and no Firebase, Sentry, or any other third-party service.
- The developer cannot access your data — there is no server to receive it, so even if we wanted to, we could not.
2. What Data We Collect
We collect no personal data whatsoever. This includes, without limitation: name, email, phone, location, device identifiers, advertising identifiers, contacts, photos, and usage behavior — none of it is collected.
3. Where Your Data Is Stored
All data generated while using Vista is stored solely on your local device by default (in the device's built-in local database), including:
- Learning progress and review history
- The points ledger (history), sessions, and achievements
- Derived stats such as streaks and word mastery
- App settings (theme, appearance, language, etc.)
This data stays on your local device by default and is never uploaded to the developer or any third party. Uninstalling the app deletes local data.
4. iCloud Sync
If you are signed in to iCloud, Vista can sync your learning data across your own devices using Apple's CloudKit private database. This data lives only in your own iCloud account, encrypted and managed by Apple — the developer has no server and cannot read or access it. Sync is optional and can be turned off anytime in iOS Settings › Apple ID › iCloud; with it off, data stays only on your local device.
5. In-App Purchases & Payments
Vista offers a one-time "Vista Pro" in-app purchase (product identifier: com.bytelink.vista.pro). This transaction is handled entirely by Apple through the App Store and StoreKit.
- It is a one-time purchase — not a subscription and does not auto-renew.
- We do not touch, collect, or store any of your payment information (such as card numbers or Apple ID).
- Purchase receipts are validated by Apple or on your device; you can "Restore Purchases" on any device signed in with the same Apple ID.
- Refund requests are governed by Apple's refund policy.
6. Local Notifications
If you enable study reminders, those notifications are scheduled and delivered locally by your device and never pass through any server. You can disable notification permission anytime in system Settings.
7. What We Do NOT Collect
Vista contains no third-party analytics SDKs, no advertising SDKs, and no tracking. We do not collect your contacts, location, photos, microphone, or browsing activity, and we do not sell or share any data with third parties.
8. Audience & Children's Privacy
Vista is suitable for general audiences and does not knowingly collect personal information from children. Because the app collects no personal data from any user, it is safe for learners of all ages.
9. Your Rights & Data Deletion
You are in full control of your data. You can erase all local learning data at any time via Settings › Clear All Data inside the app. Deleting the app removes all on-device data. To remove synced data, disable iCloud for Vista or delete the app's data in iCloud settings.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Effective Date" above. For material changes we will try to notify you within the app.
