CHUA 隐私政策

更新日期：2026 年 7 月 29 日

CHUA 是一款极简网络测速工具，用于帮助用户了解当前网络的下载速度、上传速度和网络延迟。 我们不要求注册或登录，不投放广告，不做用户追踪，也不出售任何数据。

我们不收集你的个人数据

CHUA 不收集、不存储可用于识别你的个人数据。App 内没有任何第三方分析、广告或崩溃上报组件， 也不读取设备标识符、设备型号，不申请通讯录、照片、相机、麦克风或地理位置权限。

测速记录保存在你自己的设备上

你的测速历史（下载、上传、延迟、抖动、丢包、连接类型和时间）仅保存在本机， 用于在 App 内展示历史与趋势，并向桌面小组件提供最近一次结果。 这些记录不会上传到我们的服务器。你可以在历史记录页删除单条或一键清空， 删除 App 也会一并移除这些数据。

测速过程中的技术信息

测速需要你的设备与我们的测速服务器交换数据，这一过程会用到以下技术信息：

• 公网 IP 地址：用于在 App 中向你显示当前网络出口，以及限制异常高频请求以保护服务。该地址在请求处理完成后即被丢弃，不写入数据库。
• 测速数据流：为测量速率而收发的填充数据，内容是无意义的占位字节，不含任何个人信息，用完即弃。

我们的测速服务不保存任何测速结果。

服务器日志

与绝大多数网站一样，承载官网和测速服务的服务器会生成标准访问日志， 用于排查故障和防范滥用。日志仅用于运维与安全目的，不用于分析个人行为，不与身份信息关联， 不用于广告或追踪，并会在短期内轮转删除。

第三方服务

我们使用云服务器和域名解析服务来运行官网与测速节点，除此之外 CHUA 不集成任何第三方 SDK。 App 通过 App Store 分发，Apple 可能按其自身政策处理下载与支付信息， 该部分受 Apple 隐私政策约束，我们无法获取你的支付信息。

儿童隐私

CHUA 面向普通网络用户，不主动面向儿童收集个人信息。如果你认为儿童向我们提供了个人信息， 请通过下方邮箱联系我们。

CHUA Privacy Policy

CHUA is a minimal network speed test app. It helps users understand download speed, upload speed, and network latency. CHUA requires no account or login, shows no ads, performs no tracking, and does not sell any data.

We Do Not Collect Your Personal Data

CHUA does not collect or store data that could identify you. The app contains no third-party analytics, advertising, or crash-reporting components. It does not read device identifiers or device model, and it requests no access to contacts, photos, camera, microphone, or location.

Test History Stays on Your Device

Your test history (download, upload, latency, jitter, packet loss, connection type, and timestamp) is stored only on your device. It powers the in-app history and trend views and supplies the latest result to the Home Screen widget. This history is never uploaded to our servers. You can delete individual records or clear all of them from the history screen, and deleting the app removes the data as well.

Technical Information During a Test

Running a test requires your device to exchange data with our speed test server. This involves the following technical information:

• Public IP address — shown to you in the app as your current network endpoint, and used to rate-limit abusive request volumes. It is discarded once the request completes and is never written to a database.
• Test payload — filler bytes sent and received to measure throughput. The payload is meaningless placeholder data, contains no personal information, and is discarded immediately.

Our speed test service does not store any test results.

Server Logs

Like most websites, the servers hosting our site and speed test service generate standard access logs used to troubleshoot faults and prevent abuse. These logs serve operational and security purposes only. They are not used to profile individuals, are not linked to any identity, are never used for advertising or tracking, and are rotated and deleted on a short schedule.

Third-Party Services

We use cloud servers and DNS services to run our website and speed test nodes. Beyond that, CHUA integrates no third-party SDKs. The app is distributed through the App Store; Apple may process download and payment information under its own policies, which are governed by Apple's privacy policy. We have no access to your payment information.

Children's Privacy

CHUA is intended for general network users and does not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us at the address below.
