隐私政策
最后更新日期:2026 年 4 月 27 日

1. 信息收集与使用

本应用的设计核心是隐私保护。所有图像处理和文字识别(OCR)均在您的设备端本地完成,使用 Apple Vision 框架;条码识别同样在设备本地完成,不依赖任何外部服务。

  • 我们不会收集、上传或分享您的照片、扫描图像或识别结果。
  • 除内购交易必要的网络通信外,我们不会将任何用户内容数据发送至外部服务器。
  • 我们不会收集您的姓名、地址、电话号码、电子邮箱等个人身份信息。
  • 本应用无需注册账号,不会跟踪您的使用行为,不会进行行为分析或用户画像。
  • 本应用不使用任何形式的设备指纹识别或跨应用追踪技术。

2. 相机与照片库权限

为实现文字比对与条码检测功能,本应用需要访问以下系统权限:

  • 相机权限(NSCameraUsageDescription):用于拍摄待核查文本或印刷品照片,仅在您主动使用拍摄功能时触发,不在后台运行。
  • 照片库权限(NSPhotoLibraryUsageDescription):用于选择已存储在相册中的图片,仅在您主动选择时触发。

上述权限完全由您掌控。您可随时在 iOS 系统「设置 > 隐私与安全 > 相机 / 照片」中撤销授权。撤销后相关功能将无法使用,但您已保存的本地项目数据不受影响。

3. 数据存储与保留

  • 所有照片、OCR 识别结果、条码检测结果及比对报告均仅存储在您设备的本地文件系统中(Application Support 目录)。
  • 检测项目数据通过 SwiftData 框架保存在设备本地数据库,不提供云端同步,您的内容数据不会离开您的设备。
  • 导出的 PDF 报告文件保存在您指定的本地位置,由您自行管理。
  • 当您在应用内删除检测项目时,相关图片文件、数据库记录及缩略图缓存将一并从设备中永久删除。
  • 卸载本应用时,所有本地存储的数据将随应用一并被系统清除。

本应用不存在独立于设备之外的内容数据副本,因此我们无法代您删除任何内容——删除操作完全由您在设备上控制。

4. 内购与网络通信

本应用提供应用内购买(In-App Purchase)功能以解锁高级特性。内购功能涉及以下网络通信:

  • 内购交易通过 Apple App Store 完成,所有支付信息由 Apple 处理,开发者不收集、不存储任何支付卡号或账单信息。
  • 本应用会通过 Apple StoreKit 框架向 Apple 服务器验证购买凭据,以确认您的购买状态。此过程仅传输必要的购买收据,不传输任何个人身份信息或用户内容。
  • 内购所产生的交易记录由 Apple 管理,适用 Apple 的隐私政策(https://www.apple.com/legal/privacy/)。
  • 除上述内购验证外,本应用的所有核心功能(OCR、条码检测、文字比对、PDF 生成)均在设备本地完成,不需要网络连接。

如需管理订阅、申请退款或查询购买记录,请通过 Apple App Store 账号进行操作,开发者无权直接处理退款请求。

5. 第三方服务与 SDK

除 Apple 内购框架外,本应用不集成任何第三方分析、广告、崩溃上报或数据收集 SDK,全部功能均基于 Apple 系统原生框架实现:

  • OCR 文字识别:Apple Vision Framework
  • 条码识别:Apple Vision Framework
  • 数据存储:Apple SwiftData
  • PDF 生成:Apple UIGraphicsPDFRenderer
  • 内购:Apple StoreKit Framework

唯一涉及第三方交互的渠道是:(1) 您主动点击"联系我们"后由 iOS 系统调起的邮件客户端;(2) Apple 内购流程(由 Apple 独立处理)。开发者不会自动发送任何数据。

6. 用户权利

由于本应用不收集任何个人信息,我们没有可供访问、更正、删除或导出的用户数据记录。您对存储在自己设备上的所有内容数据拥有完整控制权:

  • 访问与导出:您可随时在应用内查看所有检测项目并导出 PDF 报告。
  • 删除:您可在应用内删除单个项目,或通过卸载应用删除全部本地数据。

如您居住在欧盟(GDPR 适用地区)或加利福尼亚州(CCPA 适用地区),您同样享有上述权利,相关操作请在设备本地完成。如有其他隐私问题,请通过本政策末尾的联系方式与我们沟通。

7. 儿童隐私

本应用面向企业文字核查专业人员设计,不适合儿童使用,不会故意向 13 周岁以下(在欧盟地区为 16 周岁以下)的未成年人提供服务。

8. 政策更新

我们可能不时更新本隐私政策以反映功能变化或法规要求。更新后的政策将在应用内的「关于」页面展示,并在文件顶部标注最新更新日期。如发生以下重大变更,我们将通过应用版本更新加以通知:

  • 开始收集新类型的个人信息;
  • 将数据与第三方共享;
  • 改变数据存储或处理的地点。

继续使用本应用即表示您接受更新后的政策。

PRIVACY POLICY
Last updated: April 27, 2026

1. Information Collection and Use

Privacy is at the core of our design. All image processing and optical character recognition (OCR) is performed locally on your device using the Apple Vision framework. Barcode detection is also handled entirely on-device without relying on any external services.

  • We do not collect, upload, or share your photos, scanned images, or recognition results.
  • We do not send any user content data to external servers, except for the network communication necessary for in-app purchase transactions.
  • We do not collect personally identifiable information such as name, address, phone number, or email address.
  • The App does not require an account and does not track usage behavior, perform behavioral analytics, or build user profiles.
  • The App does not use any form of device fingerprinting or cross-app tracking.

2. Camera and Photo Library Access

To provide text comparison and barcode detection functionality, the App requires the following system permissions:

  • Camera access (NSCameraUsageDescription): Used to photograph texts or printed materials for verification. Triggered only when you actively use the capture feature and does not run in the background.
  • Photo Library access (NSPhotoLibraryUsageDescription): Used to select images already stored in your photo library. Triggered only when you actively choose to import photos.

You retain full control over these permissions and may revoke them at any time via iOS Settings > Privacy & Security > Camera / Photos. Revoking access disables the related feature but does not affect your locally saved project data.

3. Data Storage and Retention

  • All photos, OCR results, barcode detection results, and comparison reports are stored solely in the device's local file system (Application Support directory).
  • Inspection project data is saved via the SwiftData framework in the device's local database. No cloud sync — your content data never leaves your device.
  • Exported PDF reports are saved to the local path you specify and are managed entirely by you.
  • When you delete an inspection project within the App, associated image files, database records, and thumbnail cache are permanently removed.
  • Uninstalling the App causes all locally stored data to be deleted by the operating system.

Because no copy of your content data exists outside your device, we are unable to delete data on your behalf — all deletion is performed locally under your control.

4. In-App Purchases and Network Communication

The App offers In-App Purchases (IAP) to unlock premium features. IAP involves the following network communications:

  • Purchase transactions are processed through the Apple App Store. All payment information is handled by Apple — the developer does not collect or store any payment card numbers or billing information.
  • The App uses Apple's StoreKit framework to verify purchase receipts with Apple's servers. This process transmits only the necessary purchase receipt, no personally identifiable information or user content.
  • Transaction records generated by in-app purchases are managed by Apple, subject to Apple's Privacy Policy (https://www.apple.com/legal/privacy/).
  • All core functionality (OCR, barcode detection, text comparison, PDF generation) runs locally on-device and does not require a network connection, except IAP verification.

To manage subscriptions, request refunds, or review purchase history, please use your Apple App Store account. The developer cannot process refund requests directly.

5. Third-Party Services and SDKs

Aside from Apple StoreKit, the App integrates no third-party analytics, advertising, crash reporting, or data collection SDKs. All built on Apple native frameworks:

  • OCR text recognition: Apple Vision Framework
  • Barcode detection: Apple Vision Framework
  • Data persistence: Apple SwiftData
  • PDF generation: Apple UIGraphicsPDFRenderer
  • In-App Purchases: Apple StoreKit Framework

The only third-party channels: (1) the iOS mail client when you tap "Contact Us"; (2) Apple IAP flow, processed independently by Apple. No data is transmitted automatically.

6. Your Rights

Because the App does not collect personal information, we hold no user data records for you to access, correct, delete, or export. You have full control over all content data stored on your device:

  • Access & Export: View all inspection projects and export PDF reports at any time within the App.
  • Deletion: Delete individual projects within the App or remove all local data by uninstalling the App.

If you are located in the EU (GDPR) or California (CCPA), you are entitled to the same rights, exercisable locally on your device. For any other privacy concerns, please contact us.

7. Children's Privacy

The App is designed for enterprise text verification professionals and is not intended for use by children. We do not knowingly provide services to children under 13 (or under 16 in EU jurisdictions).

8. Changes to This Policy

We may update this Privacy Policy to reflect feature changes or regulatory requirements. Updated policy will be displayed on the About page within the App. We will notify you via App version updates when material changes occur:

  • We begin collecting a new category of personal information;
  • We share data with third parties;
  • We change where or how data is stored or processed.

Continued use of the App following any update constitutes acceptance of the revised policy.
