# 隐私政策 / Privacy Policy

**实时海拔仪 (Realtime Altimeter)** 是一款由独立开发者开发的 iOS 应用程序。我们非常重视您的隐私。本隐私政策旨在向您说明本应用如何收集、使用和保护您的信息。

**Realtime Altimeter** is an iOS application developed by an independent developer. We take your privacy very seriously. This Privacy Policy explains how the app collects, uses, and protects your information.

***

### 一、信息收集与使用 / Information Collection and Use

#### 1. 位置信息 / Location Information

本应用使用您的设备定位功能（GPS）来提供以下核心功能：

* 实时海拔高度显示
* 速度显示
* 经纬度坐标显示
* 日出日落时间计算
* 反向地理编码（将坐标转换为地名，通过 Apple 系统服务实现）
* 拍照水印中的位置信息

The app uses your device's location services (GPS) to provide:

* Real-time altitude display
* Speed display
* Latitude/longitude coordinates
* Sunrise/sunset time calculation
* Reverse geocoding (converting coordinates to place names via Apple's built-in services)
* Location information in photo watermarks

**位置数据仅在应用使用期间获取，不会在后台持续追踪。所有位置数据仅在您的设备本地处理，不会上传至任何服务器。**

**Location data is collected only while the app is in use and is never tracked in the background. All location data is processed locally on your device and is never uploaded to any server.**

#### 2. 气压计 / Barometer

本应用使用设备内置气压计传感器来显示大气压数据。此数据仅在设备本地处理，不会被存储或传输。

The app uses the device's built-in barometer sensor to display atmospheric pressure data. This data is processed locally on your device and is never stored or transmitted.

#### 3. 相机 / Camera

本应用提供拍照功能，允许您拍摄带有海拔和位置水印的照片。相机仅在您主动打开拍照界面时启用。拍摄的照片仅保存至您的本地相册，不会上传至任何服务器。

The app provides a camera feature that allows you to take photos with altitude and location watermarks. The camera is only activated when you open the camera view. Photos are saved only to your local photo library and are never uploaded to any server.

#### 4. 照片图库 / Photo Library

本应用仅请求「添加照片」权限，用于将带水印的照片保存至您的相册。本应用不会读取或访问您相册中的其他照片。

The app only requests "Add Photos" permission to save watermarked photos to your photo library. The app does not read or access any other photos in your library.

#### 5. 本地偏好设置 / Local Preferences

本应用使用设备本地存储（UserDefaults）保存您的偏好设置，包括：

* 高度单位（米/英尺）
* 气压单位
* 坐标显示格式
* 外观模式（跟随系统/浅色/深色）

这些设置仅存储在您的设备上，不会被传输至任何外部服务。

The app uses local device storage (UserDefaults) to save your preferences, including:

* Altitude unit (meters/feet)
* Pressure unit
* Coordinate display format
* Appearance mode (system/light/dark)

These settings are stored only on your device and are never transmitted to any external service.

***

### 二、数据共享 / Data Sharing

本应用 **不会** 与任何第三方共享您的个人数据。本应用不包含任何第三方分析工具、广告 SDK 或用户追踪功能。

The app **does not** share your personal data with any third party. The app does not contain any third-party analytics, advertising SDKs, or user tracking features.

***

### 三、网络使用 / Network Usage

本应用唯一的网络请求是通过 Apple 系统内置的反向地理编码服务（CLGeocoder），将您的坐标转换为可读的地名。此请求由 Apple 系统框架直接处理，本应用不会向任何自有或第三方服务器发送数据。

The only network request the app makes is through Apple's built-in reverse geocoding service (CLGeocoder) to convert coordinates into readable place names. This request is handled directly by Apple's system framework; the app does not send data to any proprietary or third-party servers.

***

### 四、数据存储 / Data Storage

本应用不会在任何远程服务器上存储您的数据。所有数据（位置、气压、照片、偏好设置）均仅在您的设备本地处理和存储。

The app does not store your data on any remote server. All data (location, pressure, photos, preferences) is processed and stored locally on your device only.

***

### 五、儿童隐私 / Children's Privacy

本应用不会有意收集 13 岁以下儿童的个人信息。由于本应用不收集或传输任何个人数据，因此不存在儿童隐私风险。

The app does not knowingly collect personal information from children under 13. Since the app does not collect or transmit any personal data, there is no risk to children's privacy.
