动作数据

iPhone 只在单人反应训练处于前台活动状态时读取本机动作样本；Apple Watch 在单人、双人或准心训练处于前台活动状态时读取动作样本。姿态、重力、旋转速度和用户加速度仅在设备内存中实时处理，用于反应触发与准心控制。准心训练期间，Watch 会将带会话标识、递增序号与采样时间的临时姿态包发送到已配对 iPhone；它们只用于当前前台会话。这些原始样本不会保存、不会上传，也不会用于广告或分析。离开页面、进入后台、连接持续中断或训练结束时停止采样与传输。

本机校准数据

准心训练在 iPhone 本机仅保存由五点校准计算出的派生 2×3 映射系数、校准版本、佩戴腕、表冠方向和屏幕比例，以便以后只做中心快速校准。原始校准姿态不会保存。佩戴配置、映射版本或屏幕比例不匹配时，旧映射不会继续使用，App 会要求重新完成五点校准。

附近双人训练临时数据

双人反应训练使用本地网络上的设备到设备连接，临时交换随机生成的参与者标识、反馈方案、准备状态、训练轮次标识、时钟校准消息、反应时长和本次结果。数据仅用于建立和完成当前附近训练，不会发送到我们的服务器；断开连接后 App 不保留训练历史。

我们不收集的内容

• 不创建账号，不收集姓名、昵称、电子邮件登录资料或密码。
• 不访问位置、联系人、照片、健康数据或麦克风。
• 不接入广告、分析、跨 App 追踪、云端排行榜或历史战绩服务。
• 不在后台承诺或记录抬腕触发动作。

系统权限与第三方

iPhone 的本地网络权限仅用于发现并连接附近的双人反应训练。iPhone 与 Watch 的动作传感器仅用于前台反应触发、视差和准心控制；准心训练不使用摄像头、位置或 UWB。App 使用 Apple 提供的 Core Motion、WatchConnectivity、Network.framework、RealityKit、音频和触感框架，不包含第三方 SDK。

Motion Data

iPhone reads its own motion samples only while Solo Reaction is active in the foreground; Apple Watch reads motion while Solo Reaction, Partner Reaction, or Aim Training is active in the foreground. Attitude, gravity, rotation rate, and user acceleration are processed live in device memory for reaction triggers and reticle control. During Aim Training, Watch sends temporary attitude packets with a session identifier, monotonic sequence, and sample time to the paired iPhone for the current foreground session only. Raw motion samples are not saved, not uploaded, and not used for advertising or analytics. Sampling and transmission stop when the page is left, either app backgrounds, connectivity remains interrupted, or training ends.

On-Device Calibration Data

Aim Training stores only the derived 2×3 mapping coefficients, calibration schema version, wrist, crown orientation, and screen ratio on the iPhone so later entries can use a quick center calibration. Raw calibration attitudes are not stored. If the wear configuration, mapping version, or screen ratio does not match, the old map is not used and the full five-point calibration is required again.

Temporary Nearby Partner-Training Data

Partner Reaction uses a device-to-device connection on the local network to temporarily exchange a randomly generated participant identifier, feedback profile, ready state, training-attempt identifier, clock-calibration messages, reaction time, and the current result. This data is used only to establish and complete nearby training, is not sent to our servers, and is not retained as training history after disconnection.

What We Do Not Collect

• No account, name, nickname, sign-in email, or password.
• No location, contacts, photos, health data, or microphone access.
• No advertising, analytics, cross-app tracking, cloud leaderboard, or training-history service.
• No promise or recording of background wrist-raise triggers.

System Permissions and Third Parties

Local Network permission on iPhone is used only to discover and connect to nearby partner reaction training. iPhone and Watch motion sensors are used only for foreground reaction triggers, viewing parallax, and reticle control; Aim Training uses no camera, location, or UWB. The app uses Apple-provided Core Motion, WatchConnectivity, Network.framework, RealityKit, audio, and haptic frameworks and contains no third-party SDK.
