“便携轨道检测” (Portable Track Detection) 软件（以下简称“本应用”）尊重并保护所有使用服务用户的个人隐私权。为了给您提供更准确、更有个性化的服务，本应用会按照本隐私权政策的规定使用和披露您的个人信息。
The "Portable Track Detection" software (hereinafter referred to as "this application") respects and protects the privacy rights of all users of its services. To provide you with more accurate and personalized services, this application will use and disclose your personal information in accordance with this privacy policy.

1. 我们收集的信息

1. Information We Collect

为了实现轨道检测和里程统计的核心功能，本应用在运行期间会收集以下信息：
To achieve the core functions of track detection and mileage statistics, this application collects the following information during operation:

  • 精确位置信息 (Precise Location)：我们通过 GPS 和网络基站获取您的位置，用于计算轨道里程标、记录异常波形的地理位置以及生成测绘轨迹。
  • **Precise Location: We obtain your location through GPS and network base stations to calculate track mileage markers, record the geographical location of abnormal waveforms, and generate mapped tracks.
  • 传感器数据 (Sensor Data)：本应用会读取设备的加速度计 (Accelerometer) 和重力传感器 (Gravity Sensor)，用于检测轨道的不平顺状态及震动幅值。
  • **Sensor Data: This application reads the device's accelerometer and gravity sensor to detect track irregularities and vibration amplitude.
  • 设备状态 (Device Status)：包括电池电量、系统版本，用于优化定位频率以延长设备续航。
  • **Device Status: Includes battery level and system version, used to optimize positioning frequency to extend device battery life.

2. 信息的使用

2. Use of Information

收集上述信息的唯一目的是：
The sole purpose of collecting the above information is:

  • 实时计算轨道公里标。（To calculate track kilometer markers in real time.）
  • 识别轨道病害位置。（To identify track defect locations.）
  • 生成轨道检测报告。（To generate track inspection reports.）
  • 确保在后台（熄屏）状态下检测不中断。（To ensure uninterrupted detection in the background (screen off) mode.）

本应用不会将您的位置数据或传感器数据上传到任何第三方服务器，所有检测数据均存储在您设备的本地数据库中。
**This application will not upload your location data or sensor data to any third-party servers; all detection data is stored in your device's local database. **

3. 信息存储与安全

3. Information Storage and Security

  • 本地存储：所有采集到的轨道数据均保存在本应用的私有目录数据库中。
  • Local Storage: All collected track data is stored in the application's private directory database.
  • 数据导出：数据仅在您主动点击“导出”功能时，才会生成文件供您分享或保存。
  • Data Export: Data is only generated as a file for sharing or saving when you actively click the "Export" function.

4. 权限使用说明

4. Permission Usage Instructions

  • 位置权限 (Location Permission)：用于核心的里程推算功能（Location Permission: Used for core mileage calculation functions.）。
  • 前台服务权限 (Foreground Service)：确保检测服务在您切换应用时不会被系统强制杀掉（Foreground Service Permission: Ensures the detection service is not forcibly killed by the system when you switch applications.）。
  • 通知权限 (Notification Permission)：用于向您展示当前的检测状态和实时超限警报（Notification Permission: Used to show you the current detection status and real-time over-limit alerts.）。

5. 第三方 SDK

5. Third-Party SDK

本应用使用了 Google Play Services (Location) SDK，用于获取高精度的地理位置信息。该 SDK 的隐私政策请参考 Google 相关官方文档。
This application uses the Google Play Services (Location) SDK to obtain high-precision geolocation information. Please refer to Google's official documentation for the SDK's privacy policy.

6. 您的权利

6. Your Rights

您可以随时在系统的“设置”中撤回授予本应用的位置、通知等权限。一旦撤回，相关检测功能将无法正常运作。
You can revoke the location, notification, and other permissions granted to this application at any time in your system's "Settings". Once revoked, the relevant detection functions will not function properly.
