比赛与设备

比分、赛制、逐分时间、历史和触觉设置保存在手表本地。Apple Watch 在系统连接可用时尝试把已保存的比赛快照送到配对 iPhone，手机在本地保存历史副本；手机不参与逐球记分。华为版本目前没有跨设备同步。

可选的健康与视频功能

只有你在 Apple Watch 上主动开始运动记录时，应用才请求向 Apple 健康写入该次运动；拒绝授权仍可记分。手表端目前不读取心率或位置。

在 iPhone 比赛回看或视频页，只有你主动选择运动记录并授权后，应用才读取该次运动关联的心率，用于当前页面的时间线或你选择导出的成片。心率不写入比赛历史或手表快照；离开页面或切换比赛会清除本次内存样本，两页也不会自动共享选择。成片若含心率，分享后接收者可以看到；导出前可以移除心率。

你主动选取的视频会复制到本机缓存供预览和导出，原视频不改写，应用不主动上传视频。当前选中的副本可留在页面中供重试；更换视频或下次启动时清理旧输入副本。最近一次成功导出的成片保存在应用私有目录，可再次分享；再次成功导出会删除上一份。该目录标记为不纳入系统备份；换机或卸载前，请通过系统分享菜单自行保存要保留的成片。分享接收方由你选择。

购买与数据管理

Apple 试用和买断权益通过 Apple 商店交易核对。华为免费首版的全部已实现记分功能免费，无试用到期锁定或应用内购买，不访问商店订单或网络状态，不连接互联网服务。既有比赛与设置仅保存在本表；旧权益文件不会因升级被删除。Apple 权益不转移为华为购买。应用没有自建账号、广告 SDK、应用内行为遥测或自建云存储。

当前版本没有逐条删除比赛记录的入口。卸载一端应用可删除该端应用容器中的本地副本，但不会自动删除另一设备、系统备份或已分享给外部应用的副本。商店交易记录由对应商店管理。

Matches and devices

Scores, rules, point times, match history and haptic settings are stored on the watch. When the system connection permits, the Apple Watch app attempts to send saved match snapshots to a paired iPhone, where a local history copy is stored. The phone is not needed to score each point. The planned Huawei version has no cross-device sync.

Optional health and video features

The Apple Watch app requests permission to save a workout to Apple Health only when you start a workout. Denying permission does not prevent scoring. The watch app does not currently read heart rate or location.

On iPhone, if you select a workout in match review or the video editor and grant access, the app reads heart-rate samples associated with that workout for the current page's timeline or a video you choose to export. Samples are not added to match history or watch snapshots. Leaving the page or switching matches clears the samples in memory; the two pages do not automatically share a selection. A shared video that contains heart rate exposes it to its recipients; you can remove heart rate before export.

A video you select is copied to local cache for preview and export. The original is not changed or automatically uploaded. The selected copy remains available for retries during the current session; changing videos or restarting clears the previous input copy. The most recent successful export stays in the app's private storage for sharing again; another successful export removes the previous one. This storage is marked as excluded from system backups. Before changing phones or uninstalling, use the system share sheet to save any export you want to keep.

Purchases and data management

Apple trial and lifetime access are checked against Apple store transactions. The first free Huawei release offers all implemented scoring features free, with no trial expiry lock or in-app purchases. It does not access store orders or network status, or connect to internet services. Match records and settings stay on this watch; an upgrade does not delete legacy access files. Apple access is not transferred into a Huawei purchase. The app has no account, advertising SDK, in-app behavior analytics or proprietary cloud storage.

The current version does not offer per-match deletion. Uninstalling an app can remove that device's local app container, but does not automatically delete copies on another device, system backups or files you have shared. The relevant store manages its transaction records.
