隐私政策
最后更新：2026 年 7 月
NVH Lite（以下简称"本应用"）是一款用于 NVH（噪声、振动与声振粗糙度）分析的便携式测量工具。本隐私政策说明本应用如何收集、使用及保护您的信息。
1. 信息收集与使用
麦克风权限
本应用需要访问您的设备麦克风，用于实时声学分析（FFT 频谱、声级计、倍频程分析）以及录制音频。录音数据仅存储在您的设备本地，用于后续回放与分析。您可以随时在 iOS 系统设置中关闭麦克风权限；关闭后实时分析功能将不可用。
位置权限
当您启用 GPS 速度追踪功能时，本应用会请求位置权限以记录车速信息，与音频数据同步用于 NVH 分析（如路噪、风噪测试）。位置数据仅存储在您的设备本地，不会上传至任何服务器。您可在系统设置中随时关闭位置权限。
相册权限
本应用可能请求访问您的相册，用于保存分析截图，便于您后续查阅与分享。本应用不会读取您相册中的其他内容。
文件导入
本应用支持从文件管理或其他应用导入音频/视频文件进行分析。导入的文件仅在设备本地处理。
2. 数据存储与安全
所有由本应用产生的录音、速度记录、截图和数据文件均存储在您的设备本地。本应用不会将任何数据上传至云端或第三方服务器。您可以通过 iOS 系统设置或 app 内的删除功能随时清除这些数据。
3. 数据共享
本应用不会收集、传输或共享您的个人信息给任何第三方。您可以通过 iOS 系统分享功能，自主选择将录音文件或分析截图分享给其他应用。
4. 第三方服务
本应用不嵌入任何第三方分析 SDK、广告 SDK 或数据收集服务。
5. 儿童隐私
本应用不会故意收集儿童的个人信息。如您是未成年人，请在监护人指导下使用本应用。
6. 您的权利
您可以通过以下方式管理您的数据和隐私：
- 权限管理：在 iOS 系统设置 → 隐私与安全性 中管理麦克风、位置、相册权限
- 数据删除：在应用内的"时域数据"页面删除录音记录
- 卸载：卸载本应用将删除所有本地存储的数据
7. 政策更新
本隐私政策可能不时更新。重大变更时，我们会在应用内通知。继续使用本应用即表示您同意更新后的条款。
8. 联系方式
如您对本隐私政策有任何疑问，请通过 App Store 评论区或应用的帮助页面与我们联系。
Privacy Policy
Last updated: July 2026
NVH Lite is a portable NVH (Noise, Vibration, and Harshness) analysis tool. This policy describes how we collect, use, and protect your information.
1. Information We Collect and How We Use It
Microphone Access
NVH Lite requires microphone access to perform real-time acoustic analysis (FFT spectrum, sound level metering, octave analysis) and audio recording. Recorded data is stored locally on your device for playback and analysis only. You can revoke microphone access at any time in iOS Settings; doing so will disable real-time analysis features.
Location Access
When you enable GPS speed tracking, the app requests location access to record vehicle speed alongside audio data for NVH analysis (e.g., road noise, wind noise testing). Location data is stored locally on your device and is never uploaded to any server. You can disable location access at any time in system settings.
Photo Library Access
The app may request photo library access to save analysis screenshots for your convenience. The app does not read any other content from your photo library.
File Import
NVH Lite supports importing audio and video files from the Files app or other applications for post-processing. All imported files are processed locally on your device.
2. Data Storage and Security
All data generated by NVH Lite — including recordings, speed logs, screenshots, and export files — is stored exclusively on your device. The app does not upload any data to cloud servers or third parties. You can delete this data at any time via iOS Settings or the app's built-in deletion features.
3. Data Sharing
NVH Lite does not collect, transmit, or share your personal information with any third party. You may voluntarily share recordings or screenshots through the iOS share sheet.
4. Third-Party Services
This app does not embed any third-party analytics SDKs, advertising SDKs, or data collection services.
5. Children's Privacy
NVH Lite does not knowingly collect personal information from children. If you are a minor, please use this app under the guidance of a guardian.
6. Your Rights
You can manage your data and privacy as follows:
- Permissions: Manage microphone, location, and photo library access in iOS Settings → Privacy & Security
- Data Deletion: Delete recordings in the app's "Time Data" section
- Uninstallation: Uninstalling the app removes all locally stored data
7. Policy Changes
This privacy policy may be updated from time to time. We will notify you of material changes within the app. Continued use of the app constitutes acceptance of any updated terms.
8. Contact
If you have any questions about this privacy policy, please reach out via the App Store reviews page or the in-app Help section.
