拳有 (BoxMate) is a boxing training app. You record a short clip of yourself, the app analyses your movement, and it gives you a coach-style breakdown and training sessions. This page explains exactly what happens to your data.
The short version.
Your original video is not kept. It is uploaded, analysed, and deleted immediately afterwards.
What we do keep is a short replay clip generated from your video with a skeleton drawn over it, plus the joint coordinates. People may still be recognisable in that replay clip — it is your own footage, darkened, with lines drawn on top.
You can delete any single analysis, or your whole account, from inside the app.
| Account | Your email address, or the private relay address Apple gives us if you use Sign in with Apple. |
|---|---|
| Training profile | Height, weight, stance (orthodox or southpaw), training goal, boxing experience, and arm span if you choose to enter it. |
| Video you record | Uploaded for analysis only. Deleted as soon as the analysis finishes. Never stored in our database or file storage. |
| Analysis output | A short replay clip with a skeleton overlay, per-frame joint coordinates, and the categorised findings (for example how quickly your hand returns, how your shoulder turns). |
| Training records | Sessions you complete, check-ins, your weekly plan, and the feedback taps you give us (such as “accurate” / “not quite”). |
| Technical logs | Basic server logs needed to run and debug the service. |
When you submit a clip, it is sent to our analysis server, processed frame by frame to detect your body position, and then deleted. It is not written to our database and not written to file storage.
Two things are produced and kept:
Replay clips are served through time-limited private links. A link expires and cannot be reused later.
To write the coaching commentary you read in the app, we send the text of your analysis results to a third-party AI provider, together with your training goal, your experience level, and a few technical details about the clip — how long it was, the camera angle you chose, and the measurements taken from your movement. The provider returns written text.
We do not send your video, your replay clip, any images, your email address, your name, your height, your weight, or your stance. The provider receives the categorised findings and those few values in text form only.
| Supabase | Account authentication, database, and file storage. Our project is hosted in Singapore. |
|---|---|
| Railway | Hosting for the analysis server. |
| AI provider | Generates the written coaching commentary, from text only (see above). |
| Apple | Sign in with Apple, App Store and TestFlight distribution. |
These providers process data on our behalf so the app can work. If you are in a different country from where these services run, your data is transferred and stored on their infrastructure.
If a subscription is ever added to the app, deleting your account will not by itself cancel it — subscriptions are managed in your Apple account settings.
拳有 is not intended for children under 13, and we do not knowingly collect data from them. If you believe a child has created an account, write to us and we will delete it.
Access to your data requires your own signed-in session. Replay clips and coordinate files are kept in private storage and reached only through short-lived signed links. No system is perfect; if we ever discover a breach that affects you, we will tell you.
If this policy changes in a way that affects you, we will update the date at the top and, for anything significant, tell you in the app.

拳有是一款拳击训练 App。你拍一段自己的短视频，App 分析你的动作，给出教练视角的拆解和训练课。这一页说清你的数据到底经历了什么。
先说要紧的。
你上传的原始视频不保留——上传、分析、分析结束立刻删除。
保留的是一段由你的视频画面生成、叠加了骨骼的短回放动图，以及逐帧的关节坐标。那段回放里的人物可能仍可辨认——它就是你自己的画面，压暗后叠了线条。
你可以在 App 内删除任意单条评估，或删除整个账号。
| 账号 | 你的邮箱地址；若使用 Apple 登录，则是 Apple 提供的中转地址。 |
|---|---|
| 训练资料 | 身高、体重、站架（正架或反架）、训练目标、拳龄，以及你选填的臂展。 |
| 你拍的视频 | 仅用于分析。分析一结束即删除，从不写入我们的数据库或文件存储。 |
| 分析产出 | 一段叠加骨骼的短回放动图、逐帧关节坐标，以及分档的观察结果（例如收手快慢、肩部转动情况）。 |
| 训练记录 | 你完成的训练、打卡、本周计划，以及你点的反馈（例如「准」／「不太准」）。 |
| 技术日志 | 运行和排错所必需的基础服务器日志。 |
你提交的视频会发送到我们的分析服务器，逐帧检测身体位置，然后被删除。它不写入数据库，也不写入文件存储。
产生并保留两样东西：
回放动图通过限时私有链接提供，链接会过期，之后无法再次使用。
为了生成你在 App 里读到的教练点评，我们会把分析结果的文字，连同你的训练目标、拳龄，以及这段视频的少量技术信息（时长、你选择的拍摄角度、从动作中测算出的数值），发送给第三方 AI 服务，由它返回文字内容。
我们不会发送你的视频、回放动图、任何图像、邮箱地址、姓名，也不会发送你的身高、体重和站架。对方收到的只是文字形式的分档结果与上述少量数值。
| Supabase | 账号认证、数据库与文件存储。我们的项目位于新加坡。 |
|---|---|
| Railway | 分析服务器的托管。 |
| AI 服务商 | 生成教练点评文字，仅接收文字（见上）。 |
| Apple | Apple 登录、App Store 与 TestFlight 分发。 |
这些服务商代表我们处理数据，App 才能运行。如果你所在的国家与这些服务运行的地点不同，你的数据会被传输并存储在他们的基础设施上。
若将来 App 加入订阅，删除账号本身不会取消订阅——订阅需在你的 Apple 账户设置中管理。
拳有不面向 13 岁以下儿童，我们也不会有意收集他们的数据。如果你认为有儿童注册了账号，请写信告诉我们，我们会删除。
访问你的数据需要你自己已登录的会话。回放动图与坐标文件存放在私有存储中，只能通过限时签名链接访问。没有系统是完美的；如果我们发现了影响到你的数据泄露，会告知你。
如果本政策发生影响到你的变更，我们会更新页首日期；重要变更会在 App 内告知你。
