最后更新日期 / Last Updated: 2026年10月22日 / October 22, 2026

中文版本

一、适用范围

本隐私政策适用于感角 AngleSense（以下简称“本应用”）。本应用是一款完全离线运行的角度测量与挑战工具，不提供账号系统、网络内容、云同步、广告或在线服务。

二、我们不收集的数据

本应用不会收集、上传、出售或共享您的个人信息，包括但不限于：

• 姓名、电话号码、电子邮件地址或其他身份信息；
• 精确位置、通讯录、照片、音频、相机内容或文件；
• 设备标识符、IP 地址、广告标识符或使用行为；
• 崩溃分析、广告、统计或跟踪数据。

本应用不包含第三方广告、分析或跟踪 SDK，也不会向开发者或任何第三方服务器发送数据。

三、设备角度数据

为了提供角度测量功能，本应用会在设备本地读取以下数据：

• iPhone Duo：通过 Apple 提供的系统接口读取设备铰链的状态和角度；
• 其他受支持的 iPhone 和 iPad：通过 Apple Core Motion 读取设备运动数据，用于计算设备相对于重力方向的倾角。

这些角度和运动数据仅在当前设备上实时处理，不会上传、共享或用于识别您。应用进入后台或相关页面关闭后，会停止不再需要的运动数据更新。

四、本地存储的数据

本应用可能在您的设备本地保存：

• 角度挑战结果，例如目标角度、实际角度、误差、测量模式和完成时间；
• 应用设置，例如显示精度、自动完成挑战和触觉反馈偏好。

这些数据仅存储在本应用的本地容器中，不会同步到云端或发送给开发者。您可以在应用的“设置”页面清除全部挑战记录；卸载本应用也会删除由本应用保存的本地数据。

五、系统权限

在普通 iPhone 或 iPad 上使用倾角功能时，系统可能请求“运动与健身”权限。该权限仅用于在设备本地计算倾角。如果您拒绝权限，相关倾角功能将无法使用，但本应用不会通过其他方式获取这些数据。

六、联网、Cookie 与第三方服务

本应用本身不发起网络请求，不使用 Cookie，也不集成第三方在线服务。Apple 可能为了 App Store 分发、下载和系统权限管理而独立处理相关信息；该等处理受 Apple 隐私政策约束。

七、儿童隐私

本应用不会有意收集任何用户（包括儿童）的个人信息。由于本应用不提供账号、社交、广告或网络内容，也不会建立儿童用户档案。

八、数据安全与保留

本应用采用 iOS/iPadOS 提供的应用沙盒存储本地数据。挑战记录和设置会保留在设备上，直至您在应用内清除、卸载本应用，或由系统移除相关数据。

九、隐私政策更新

如果本应用未来新增联网、第三方服务或新的数据处理方式，我们会在功能启用前更新本隐私政策，并在适用时重新请求您的授权。更新后的政策将在本页面公布。

1. Scope

This Privacy Policy applies to AngleSense (the “App”). The App is an entirely offline angle measurement and challenge utility. It does not provide accounts, network-delivered content, cloud synchronization, advertising, or online services.

2. Data We Do Not Collect

The App does not collect, upload, sell, or share personal information, including:

• Your name, phone number, email address, or other identity information;
• Precise location, contacts, photos, audio, camera content, or files;
• Device identifiers, IP addresses, advertising identifiers, or usage behavior;
• Crash analytics, advertising, statistics, or tracking data.

The App contains no third-party advertising, analytics, or tracking SDKs and sends no data to the developer or any third-party server.

3. Device Angle Data

To provide angle measurement features, the App reads the following data locally on your device:

• iPhone Duo: hinge status and angle through system APIs provided by Apple;
• Other supported iPhone and iPad devices: motion data through Apple Core Motion to calculate the device’s inclination relative to gravity.

Angle and motion data is processed in real time only on the current device. It is not uploaded, shared, or used to identify you. Motion updates that are no longer needed stop when the App enters the background or the relevant screen closes.

4. Data Stored Locally

The App may store the following information locally on your device:

• Angle challenge results, such as the target angle, measured angle, error, measurement mode, and completion time;
• App preferences, such as display precision, automatic challenge completion, and haptic feedback settings.

This information remains inside the App’s local container. It is not synchronized to the cloud or sent to the developer. You can clear all challenge history from the Settings screen. Uninstalling the App also removes data stored by the App locally.

5. System Permissions

When using inclination features on a regular iPhone or iPad, the system may request Motion & Fitness permission. This permission is used only to calculate inclination locally. If you deny permission, the related inclination features will be unavailable, and the App will not attempt to obtain the data in another way.

6. Network Access, Cookies, and Third-Party Services

The App itself makes no network requests, uses no cookies, and integrates no third-party online services. Apple may independently process information required for App Store distribution, downloads, and system permission management. Such processing is governed by Apple’s Privacy Policy.

7. Children’s Privacy

The App does not knowingly collect personal information from any user, including children. It provides no accounts, social features, advertising, network content, or child profiles.

8. Data Security and Retention

The App stores local data within the application sandbox provided by iOS and iPadOS. Challenge history and preferences remain on the device until you clear them in the App, uninstall the App, or the operating system removes the related data.

9. Changes to This Privacy Policy

If the App adds networking, third-party services, or new data processing practices in the future, we will update this Privacy Policy before enabling those features and request permission again when applicable. The updated policy will be published on this page.
