Privacy Policy 用户隐私政策

1. Introduction 1. 前言与介绍

Welcome to SiteReport. SiteReport is a professional mobile inspection recording tool designed for engineering inspections, construction acceptance, property inspection, safety inspection, and equipment maintenance. We are highly committed to protecting the privacy of our users. This Privacy Policy details how we collect, use, and protect your information when you use our services.

欢迎使用 SiteReport！SiteReport 是一款面向工程巡检、施工验收、物业检查、安全检查和设备维护等场景的专业移动端巡检记录工具。我们高度重视用户的隐私保护。本隐私政策详细阐述了您在使用我们的服务时，我们如何收集、使用和保护您的个人信息。

2. Data Collection 2. 我们如何收集信息

To provide stable inspection services, we may collect the following categories of information during your usage:

为了能够向您提供正常、稳定的巡检记录与报告导出服务，我们在您使用过程中可能会收集或需要您授权以下信息：

• Field Photos & Camera Access: Since the core feature is capturing evidence, the App requires camera and storage access permissions to take photos, link them to inspection items, and archive them locally. 现场照片与相机权限： 鉴于巡检取证核心功能的需要，应用需要申请相机和文件读写权限，以便为具体的检查项拍摄证据照片，并在本地进行分类归档。
• GPS & Location Information: With your explicit permission, we record geographic coordinates (latitude, longitude), elevation, and location accuracy to embed GPS watermarks on captured photos. We also provide offline reverse geocoding to automatically resolve city and country information from coordinates. GPS 定位与地理位置信息： 在您授权定位权限后，我们将读取地理坐标（经纬度）、海拔以及定位精度，用于在拍照时生成带有地理防篡改的水印，并在本地反查出具体省份和城市以生成验收报告。
• E-Signatures: For engineering and client acceptance validation, you may perform e-signing inside the app. Signatures are saved strictly on your local device for integration into the generated PDF reports. 电子签名： 为了满足工程或物业的验收确认，我们在应用内提供了手写签名功能。该签名仅以图片形式保存在您本地，用于拼装生成 PDF 报告。
• User-Configured Cloud Storage Servers: The App supports uploading reports to personal servers (FTP, SFTP, WebDAV, SMB/NAS). The configuration profiles (host, port, credentials) are stored securely in local app storage (encrypted via Android MMKV/DataStore) and are used only when you trigger synchronization. 用户配置的第三方存储服务器： App 支持由用户自主配置并同步数据至自建服务器（如 FTP、SFTP、WebDAV、NAS 存储）。此类凭证信息在本地加密存储，仅在您手动触发上传时使用，我们绝对不会获取此类第三方凭证。
• Google SDK Telemetry: If you sign in via Google Account, make in-app purchases, or interact with ads, the integrated Google SDKs may collect related identifiers, Google ID tokens, purchase billing records, and anonymous device state diagnostics. Google SDK 基础信息： 当您使用 Google 账号登录、发起应用内购买/订阅或进行广告交互时，集成的 Google SDK 会收集对应的账户标识、Google ID 令牌、购买记录及设备状态标识符。

3. Information Usage 3. 信息的使用目的

We utilize the collected information strictly for the following purposes:

我们使用和处理上述收集的信息，严格受限于以下目的：

1. Inspection Functionality: Managing your projects, resolving customized templates, capturing inspection photos, and generating PDF reports.
2. 基础功能交付：建立与管理巡检项目、匹配巡检模板、处理拍照以及最终拼装生成专业的 PDF 报告。
3. Location Verification: Overlaying timestamps and GPS watermarks on photos to serve as inspection evidence for project supervisors.
4. 定位留痕验证：为照片及验收单据附加不可篡改的 GPS 坐标与时间戳，作为真实有效的巡检证据供工程或客户核实。
5. Pro License Billing: Facilitating in-app purchases (Pro upgrade, no-watermark PDF features) through Google Play Billing.
6. 专业版开通：通过 Google Play 结算框架为用户办理付费订阅、去水印升级及高级功能解锁。
7. Service Performance Analysis: Resolving application crashes, performance lags, and diagnosing anonymous usage metrics to improve stability.
8. 应用稳定性优化：收集匿名偶发崩溃日志、卡顿报告，用于诊断并改进核心相机与报告生成的排查机制。

4. Data Security 4. 数据安全与存储

Because SiteReport values user security and follows an offline-first design pattern:

因为 SiteReport 秉承安全至上和离线优先的原则：

• All inspection database files are saved in the app's secure private sandbox directory. Android OS prevents unauthorized applications from accessing this sandbox.
• 所有的巡检数据库、检查详情均保存在 App 独立的私有沙盒目录下，Android 系统沙盒保护机制能有效杜绝外部程序窃取。
• We secure server credentials, billing states, and key settings using Tencent MMKV and Android Preferences, utilizing encrypted storage strategies where appropriate.
• 用户的自建服务器配置、专业版购买凭证等敏感配置信息均经过二次安全混淆，保存在受保护的本地存储（MMKV / DataStore）中。
• If you choose to uninstall the application, all local databases, custom templates, and inspection items within the sandbox will be permanently deleted. We advise backing up reports (exporting as PDF or uploading to your NAS/SFTP) before deleting the app.
• 若您直接卸载应用程序，沙盒内所有未导出的本地巡检记录、自定义模板和数据都将被永久抹除。我们建议您在卸载前将重要的报告打包导出为 PDF，或者同步到您的自建服务器中。

5. Third-Party Services 5. 第三方SDK与服务

Our application incorporates third-party SDKs to implement vital features. These providers may collect data independently subject to their own policies:

为支持部分支付、统计、定位等核心场景，应用集成了授权的第三方 SDK 服务，这些服务商的信息收集需遵循其自身的隐私政策：

6. Children's Privacy 6. 未成年人隐私保护

SiteReport is directed towards adult personnel executing professional inspections and building supervision. We do not knowingly collect personal identifiable information from children under the age of 13. If we discover a child under 13 has provided us with personal information, we will take immediate steps to delete this data.

SiteReport 主要供具有民事行为能力的专业施工监理、物业巡检等成年从业人员使用。我们不会主动收集或要求 13 岁以下未成年人的个人信息。一旦我们发现并证实未成年人在未获得监护人同意的前提下提供了个人信息，我们将第一时间对其进行清理。
