最后更新：2026 年 6 月 24 日
我们不收集任何个人身份信息。节拍器 Pulse 没有账号系统，不要求注册或登录，也不包含任何第三方分析、广告或追踪 SDK。我们不会从你的设备收集、传输或与任何人分享数据。
你的设置与预设（速度 BPM、拍号、细分、重音、音色等）仅保存在你的设备本地，由 App 在本机存储。这些数据不会离开你的设备，也不会同步到任何服务器。卸载 App 即会删除这些数据。
调音器功能需要使用麦克风来听到你的乐器并检测音准。音频仅在你的设备本地实时处理，用于计算音高；我们不录制、不存储、不上传任何音频。仅在你打开调音器时才会使用麦克风，系统会先向你请求授权。
App 完全离线运行，不需要网络连接，也不向任何服务器发送数据。我们不使用任何第三方分析、广告网络或数据代理。
本 App 不收集任何用户数据，适合所有年龄使用，并符合面向儿童的隐私保护要求（不进行追踪、不投放定向广告）。
因为数据从不离开你的设备，也不上传到云端，所以不存在数据在传输或服务器侧泄露的风险。
如果未来版本引入任何会处理数据的新功能，我们会在发布前更新本页面并修改"最后更新"日期。

We do not collect any personally identifiable information. The app has no account system and requires no sign-up or login. It contains no third-party analytics, advertising, or tracking SDKs. We do not collect, transmit, or share any data from your device.
Your settings and presets (BPM, time signature, subdivisions, accents, sounds, etc.) are stored only locally on your device. This data never leaves your device and is not synced to any server. Uninstalling the app deletes this data.
The tuner feature uses the microphone to hear your instrument and detect pitch. Audio is processed entirely on-device in real time to compute pitch; we do not record, store, or upload any audio. The microphone is used only while the tuner is open, and the system asks for your permission first.
The app runs fully offline, requires no network connection, and sends no data to any server. We use no third-party analytics, ad networks, or data brokers.
The app collects no user data, is suitable for all ages, and complies with privacy requirements for children's apps (no tracking, no targeted advertising).
Because data never leaves your device and is not uploaded to the cloud, there is no risk of data being exposed in transit or on a server.
If a future version introduces any feature that processes data, we will update this page and the "Last updated" date before release.
