How VideoStreamPerf handles your information on macOS

Last updated: March 29, 2026

English

This Privacy Policy describes how VideoStreamPerf (“the App”), a macOS application for video stream performance testing and analysis, handles information. It is intended to meet common expectations for the Apple App Store and applicable privacy guidelines.

1. Summary

The App is designed to perform measurements and reporting on your Mac. We do not use the App to track you across other companies’ apps or websites, and we do not collect personal data through the App for sale to data brokers. Performance and test data you generate stay under your control on your device unless you choose to export or share files yourself.

2. Data we collect

The App does not collect the categories of data that Apple lists for “Data Linked to You” or “Data Used to Track You” in the way a typical analytics or ad SDK would. Our App Store privacy declarations (Privacy Nutrition Labels and, where applicable, Privacy Manifest) state that we do not declare user data collection types for tracking or sale.

3. Data processed on your device

To provide video stream performance testing, the App may process on your Mac information such as frame timing, latency, jitter, scores, and related metrics derived from the streams and scenarios you configure. This processing is performed locally to show charts, statistics, and optional exports (for example PDF or CSV) that you initiate. We do not receive this content on our servers through the App because the App does not transmit it to us by design.

4. Tracking

We do not use the App to track you. We do not use advertising identifiers in the App for cross-app or cross-site tracking, and we do not combine your activity in the App with third-party advertising profiles.

5. Apple frameworks and system APIs

The App uses Apple-provided system capabilities needed for macOS performance work. Our Privacy Manifest documents use of restricted APIs where required by Apple—for example, access related to system boot timing for measuring elapsed time between events during testing (declared reason consistent with Apple’s documentation, e.g. measurement of intervals while the App is in use). Such use is not for identifying you personally.

6. Third parties

  • Apple: Distribution, updates, crash or diagnostic data, and App Store processes are subject to Apple’s Privacy Policy and your device settings.
  • Your choices: If you email files or use other services outside the App, those services have their own policies.

7. Children’s privacy

The App is not directed at children under 13 (or the minimum age required in your region). We do not knowingly collect personal information from children through the App.

8. Regional rights

Depending on where you live, you may have rights to access, correct, or delete personal information, or to object to certain processing. Because the App does not operate a user account or cloud back end for app data as described above, most information exists only on your device or in files you export. You may manage files on your Mac and use App Store support channels for account-related requests that involve Apple.

9. Changes

We may update this policy when the App or legal requirements change. The “Last updated” date at the top will be revised. Material changes may also be noted through the App Store or in-app notices where appropriate.

隐私政策

最近更新:2026 年 3 月 29 日

本隐私政策说明 VideoStreamPerf(“本应用”)这款用于 macOS 视频流性能测试与分析的桌面应用如何处理信息,并力求符合 Apple App Store 及常见隐私合规要求。

1. 概要

本应用旨在您的 Mac 上完成测量与报告。我们不会通过本应用跨其他公司的 App 或网站对您进行跟踪,也不会通过本应用收集个人数据并出售给数据经纪人。您在使用过程中产生的性能与测试数据默认保留在您的设备上,由您自行掌控;除非您主动导出或分享文件。

2. 我们收集的数据

本应用不会以典型分析或广告 SDK 的方式收集 Apple 在“与您关联的数据”或“用于跟踪您的数据”中所列类别的数据。我们在 App Store 的隐私声明(隐私营养标签及适用的 Privacy Manifest)中说明:未声明为用于跟踪或出售的用户数据收集类型。

3. 在设备上处理的数据

为提供视频流性能测试,本应用可能在您的 Mac 上处理与您配置的流与场景相关的信息,例如帧时序、延迟、抖动、评分及相关指标。上述处理在本地进行,用于展示图表、统计信息,以及由您主动发起的导出(例如 PDF 或 CSV)。本应用设计上不会将此类内容传输至我们的服务器。

4. 跟踪

我们不会使用本应用对您进行跟踪。我们不在本应用中使用广告标识符进行跨 App 或跨站跟踪,也不会将您在本应用中的活动与第三方广告画像关联。

5. Apple 框架与系统 API

本应用使用 Apple 提供的系统能力以完成 macOS 上的性能相关工作。我们的 Privacy Manifest 会按 Apple 要求声明受限 API 的使用——例如为在测试期间测量事件之间经过的时间而访问与系统启动时间相关的信息(声明理由与 Apple 文档一致,例如用于应用使用期间的间隔测量)。该等使用并非用于识别您的个人身份。

6. 第三方

  • Apple:分发、更新、崩溃或诊断数据以及 App Store 相关流程受 Apple 隐私政策 及您设备上的设置约束。
  • 您的选择:若您通过邮件发送文件或使用本应用以外的其他服务,应遵守相应服务条款与隐私政策。

7. 儿童隐私

本应用并非面向未满 13 周岁(或您所在司法辖区规定的最低年龄)的儿童。我们不会通过本应用故意收集儿童的个人信息。

8. 地区权利

根据您所在地区,您可能享有访问、更正或删除个人信息,或对部分处理提出异议等权利。由于本应用不就上述数据运营用户账户或云端后端,多数信息仅存在于您的设备或您导出的文件中。您可在 Mac 上自行管理文件;与 Apple 账户相关的事项请通过 App Store 支持渠道处理。

9. 变更

当本应用或法律要求发生变化时,我们可能更新本政策。文首的“最近更新”日期将随之修订。重大变更也可能通过 App Store 或应用内说明等方式提示。

10. 联系方式

若您对 VideoStreamPerf 的隐私有疑问,请发送邮件至 fan1056218492@gmail.com。您也可通过 Mac App Store 产品页上的支持方式联系我们。
