隐私政策
最后更新日期：2026年10月16日
本隐私政策说明在您使用 LCGoose 应用程序（"本应用"）时，我们如何收集、使用和保护您的信息。本应用是一款配合特定 USB 外接录音设备使用的工具，提供声级（分贝）检测、设备录音文件分析与设备校时功能。
1. 我们收集的信息
本应用的核心功能在您的设备本地运行，我们尽可能减少数据收集：
- 麦克风音频：用于实时计算声压级（分贝）。测量期间，本应用会在您的手机本地保存一份录音文件，用于回放和生成噪声报告。录音仅保存在本机，不会上传到任何服务器，卸载本应用会一并删除这些录音。
- 位置信息：在您生成噪声检测报告时，本应用会请求位置权限，用于在报告中标注测量地点。位置仅写入您本地生成的报告，不会上传。拒绝位置权限不影响报告生成，只是报告中不显示地点。
- 外接设备文件：在您通过系统"文件"应用主动授权设备目录后，本应用读取设备上的录音文件（如 WAV）用于分贝/噪声分析，并可向设备写入校时配置文件。文件在本地处理，不会上传。
本应用不收集任何设备标识、使用统计或诊断信息，不包含任何广告、统计或追踪 SDK，也不需要注册或登录账号。
2. 权限说明
- 麦克风：用于分贝/声级检测。仅在您进入相关功能并授权后使用，不在后台开启。
- 位置：在您生成噪声报告时请求，仅用于在报告中标注测量地点，可随时在系统设置中关闭。
- 文件访问：通过系统"文件"应用的目录授权（UIDocumentPicker）读取您主动选择的外接设备目录，访问范围仅限您授权的目录。
以上权限默认关闭，仅在相关功能需要时请求。拒绝某项权限不影响其他无关功能的使用。
3. 信息的使用
我们仅将收集的信息用于提供上述核心功能、保障应用安全稳定以及响应您的支持请求。我们不会将您的音频、报告或设备文件用于广告或出售给第三方。
4. 信息的存储与共享
分贝检测、报告生成与设备文件分析均在您的设备本地完成，相关内容默认不离开您的设备。我们不会出售您的个人信息。仅在遵守适用法律或响应合法的政府/司法要求时，才可能披露必要信息。
5. 未成年人
本应用面向一般用户。我们不会在知情情况下收集未成年人的个人信息。如您认为未成年人向我们提供了信息，请通过下方邮箱联系我们。
6. 您的权利
由于数据主要存储在您的设备本地，您可通过删除应用内文件或卸载应用来删除相关数据。您也可随时在系统设置中管理各项权限。
7. 政策更新
我们可能适时更新本政策。重大变更将通过应用内提示等适当方式告知您。

Privacy Policy
Last updated: October 16, 2026
This Privacy Policy explains how we collect, use, and protect your information when you use the LCGoose application (the "App"). The App is a tool used together with a dedicated USB external audio-recording device, providing sound-level (decibel) measurement, analysis of device recording files, and device time synchronization.
1. Information We Collect
The App's core features run locally on your device, and we minimize data collection:
- Microphone audio: used to compute sound pressure level (decibels) in real time. While measuring, the App saves a recording on your phone for playback and noise-report generation. Recordings stay on your device and are never uploaded to any server; uninstalling the App deletes them.
- Location: when you generate a noise report, the App requests location permission to label the measurement location in the report. Location is written only into your locally generated report and is not uploaded. Declining location permission does not prevent report generation; the report simply shows no location.
- External device files: after you authorize a device folder via the system Files app, the App reads recording files (e.g., WAV) from the device for decibel/noise analysis and may write a time-sync configuration file back to the device. Files are processed locally and are not uploaded.
The App does not collect any device identifiers, usage statistics, or diagnostic data, contains no advertising, analytics, or tracking SDKs, and requires no account registration or login.
2. Permissions
- Microphone: for decibel/sound-level measurement. Used only after you enter the feature and grant permission; never in the background.
- Location: requested when you generate a noise report, only to label the measurement location in that report; can be turned off in system settings anytime.
- File access: reads the external device folder you actively select, via the system Files app folder authorization (UIDocumentPicker); access is limited to the folder you authorized.
These permissions are off by default and requested only when a feature needs them. Declining a permission does not affect unrelated features.
3. How We Use Information
We use collected information solely to provide the core features above, keep the App secure and stable, and respond to your support requests. We do not use your audio, reports, or device files for advertising, nor sell them to third parties.
4. Storage & Sharing
Decibel measurement, report generation, and device-file analysis are performed locally on your device, and such content does not leave your device by default. We do not sell your personal information. We may disclose necessary information only to comply with applicable law or respond to lawful government/judicial requests.
5. Children
The App is intended for general users. We do not knowingly collect personal information from minors. If you believe a minor has provided us information, please contact us at the email below.
6. Your Rights
Since data is primarily stored locally on your device, you can delete related data by removing in-app files or uninstalling the App. You can also manage permissions anytime in system settings.
7. Policy Updates
We may update this policy from time to time. Material changes will be communicated through appropriate means such as in-app notices.
