隐私政策
生效日期：2026 年 8 月 21 日
我们如何处理音频
弦准使用设备麦克风实时判断乐器音高。音频仅在你的设备上即时分析，不会被录制、保存、上传或分享。关闭 App 或将其切换到后台时，麦克风分析会停止。
数据收集
当前版本不创建账户，不包含广告、分析或跟踪服务，也不收集个人数据。基准音高偏好只保存在你的设备上。
权限控制
你可以随时在 iPhone 的“设置 → 隐私与安全性 → 麦克风”中关闭弦准的麦克风权限。关闭权限后，调音功能将无法识别音高。
政策更新
如果未来版本的数据处理方式发生变化，本页面会同步更新，并在需要时重新征得你的同意。

StringTrue Privacy Policy
Effective: August 21, 2026
Audio processing
StringTrue uses the device microphone to detect musical pitch in real time. Audio is processed solely on your device and is never recorded, stored, uploaded, or shared. Microphone analysis stops when the app is closed or moves to the background.
Data collection
The current version has no accounts, advertising, analytics, or tracking and does not collect personal data. Your reference-pitch preference stays on your device.
Permission control
You can disable microphone access at any time in iPhone Settings → Privacy & Security → Microphone. Pitch detection will not work without microphone access.
Updates and contact
If our data practices change, this policy will be updated. For privacy or app questions, visit the StringTrue support page.
