Tennis Go for iPhone — Privacy Policy
Tennis Go analyzes your tennis swing on your iPhone and compares it with a reference stroke. This policy covers the Tennis Go iPhone app. The tennisgo.app website is a separate service.
Short version
Your videos and results stay on your iPhone. The app has no account, sends nothing to our servers, and has no ads, analytics, or tracking.
What the app uses
- Camera: to record your swing when you choose to record.
- Microphone: recorded with the video. The sound of the hit marks the moment of contact. In the shadow-swing drill, the sounds the app plays are recorded to time your swing.
- Videos you pick: when you choose a video from Photos, the app receives only that video. It does not get access to the rest of your library.
Where your data goes
All recording, analysis, results, and history are processed and stored on your iPhone, inside the app's own storage. We do not receive, collect, or store your videos, audio, analysis results, or any personal information. The app does not use third-party SDKs that collect data.
Like other app data, this storage may be included in your iPhone backups (iCloud or computer) according to your own device settings. Those backups are handled by Apple or your computer, not by us.
Deleting your data
You can delete any saved analysis in the app. Deleting the app removes all of its data from your iPhone.
Children
The app does not knowingly collect any information from anyone, including children.
Changes
If a future version changes how data is handled (for example, an optional online feature), we will update this page and the app's privacy details on the App Store before that version is released.

Tennis Go iPhone 版 — 隐私政策
Tennis Go 在你的 iPhone 上分析网球挥拍，并与示范动作对比。本政策适用于 Tennis Go iPhone 应用；tennisgo.app 网站是另一项服务。
简要说明
你的视频和分析结果只保存在你的 iPhone 上。应用无需账号，不向我们的服务器发送任何数据，没有广告、统计或追踪。
应用使用的权限
- 相机：在你选择录制时拍摄挥拍。
- 麦克风：随视频一起录制。击球声用来确定击球瞬间；在影子挥拍练习中，会录下应用播放的声音来判断挥拍时机。
- 你选择的视频：从照片中选择视频时，应用只能读取你选中的那一段，无法访问相册中的其他内容。
数据去向
录制、分析、结果和历史记录都在你的 iPhone 上处理，并保存在应用自己的存储空间中。我们不会接收、收集或存储你的视频、音频、分析结果或任何个人信息。应用没有使用会收集数据的第三方 SDK。
与其他应用数据一样，这些数据可能会按照你的设备设置包含在 iPhone 备份（iCloud 或电脑）中；这些备份由 Apple 或你的电脑处理，与我们无关。
删除数据
你可以在应用中删除任意一条已保存的分析。删除应用会从 iPhone 上移除它的全部数据。
儿童
应用不会有意收集任何人的信息，包括儿童。
政策变更
如果以后的版本改变了数据处理方式（例如增加可选的在线功能），我们会在该版本发布前更新本页面和 App Store 上的隐私信息。
