隐私政策
节拍伴侣不收集你的任何数据。
我们收集什么
什么都不收集。App 没有账号系统，不需要登录，不要求你填写任何资料，也不含任何统计或分析工具。
网络连接
App 自身不发起任何网络连接：没有服务器、没有接口调用、没有第三方 SDK。发出节拍声、计算时间、驱动震动这些事情全部在你的设备上完成。
数据存在哪里
- 在你的设备上。三档速度记忆、每个场景的节拍设置、点击音音色存在本机；App 与它的主屏幕小组件、表盘复杂功能之间也只在设备本地共享当前状态。
- 在你自己的 iCloud 里。上面这些设置会通过系统的 iCloud 键值存储，在你用同一个 Apple ID 登录的设备之间同步。这份数据存在你自己的 iCloud 账户下，开发者既无法读取也无法访问。
- 在你和你的手表之间。iPhone 与配对的 Apple Watch 直接同步当前状态（经由系统的设备间通道），不经过任何服务器。
运动与健身数据
只有在跑步时你主动开启「步频定速」之后，App 才会读取步频，用来把节拍速度对齐到你的步频。步频只在本机内存里实时处理，用于算出这个速度，不留存、不上传。停止采集或退出 App 即停止读取。
权限
- 运动与健身（步频）——只用于上面那件事。可以随时在「设置 → 隐私与安全性 → 运动与健身」里关掉，关掉后其余功能不受影响。
- 后台音频——节拍声需要在锁屏、切到别的 App 之后继续响。这是 App 唯一声明的后台模式。
除此之外不申请任何权限：没有定位、没有通讯录、没有麦克风、没有相机、不发送通知。
第三方
没有广告、没有统计分析、没有第三方 SDK。因此也没有任何数据被分享或出售给第三方。
儿童
因为不收集任何数据，所以也不收集儿童的数据。
你的控制
- 删除 App 即删除本机上的全部数据。
- iCloud 里的那一份：在「设置 → Apple ID → iCloud → 管理账户存储」里找到节拍伴侣并删除。
政策变更
这份政策如果有变化，会更新本页顶部的生效日期。

Privacy Policy
TempoMate collects no data about you.
What we collect
Nothing. The app has no accounts, no sign-in, no profile, and no analytics.
Network connections
The app makes no network connections of its own: no server, no API calls, no third-party SDKs. Playing the click, keeping time, and driving haptics all happen on your device.
Where your settings live
- On your device. Your three tempo memories, each scene's rhythm settings, and the click timbre are stored locally. The app shares its current state with its own home-screen widget and watch complication on-device only.
- In your own iCloud. Those settings sync between devices signed in to the same Apple ID using the system's iCloud key-value store. That data lives in your iCloud account; the developer cannot read or access it.
- Between you and your watch. Your iPhone syncs its current state directly with a paired Apple Watch over the system's device-to-device channel, not through any server.
Motion & Fitness data
Only after you start cadence matching during a run does the app read your cadence, in order to align the tempo with your steps. Cadence is processed in memory on the device to compute that tempo, and is never stored or uploaded. It stops the moment you stop collecting or leave the app.
Permissions
- Motion & Fitness (cadence) — used only for the above. You can turn it off any time in Settings → Privacy & Security → Motion & Fitness; everything else keeps working.
- Background audio — the click must keep playing while the screen is locked or you switch apps. This is the only background mode the app declares.
No other permissions are requested: no location, contacts, microphone, camera, or notifications.
Third parties
No ads, no analytics, no third-party SDKs — and therefore no data shared with or sold to anyone.
Children
Since no data is collected at all, no data is collected from children.
Your control
- Deleting the app deletes all of its local data.
- For the iCloud copy: Settings → Apple ID → iCloud → Manage Account Storage, choose TempoMate, and delete.
Changes
If this policy changes, the effective date at the top of this page changes with it.
