Stable Altimeter Privacy Policy

1. Location Information / 位置数据

Stable Altimeter uses precise location in the foreground, when you grant location permission, to display GPS altitude, latitude, longitude, location accuracy, and speed, and to calculate trip distance and elevation statistics when you start a trip. The app does not request or use background location.

在您授予位置权限后，Stable Altimeter 仅在前台使用精确位置，用于显示 GPS 海拔、纬度、经度、定位精度和速度，并在您主动开始行程时计算行程距离和海拔统计。应用不请求或使用后台位置。

Location is used for the app's measurement features and is not used for advertising. The developer does not operate a server intended to store precise GPS location.

位置数据用于应用的测量功能，不用于广告。开发者不运营用于保存精确 GPS 位置的服务器。

2. Measurement and Sensor Data / 测量与传感器数据

The app processes GPS-derived altitude, coordinates, accuracy, speed, timestamps, and calculated measurement values on your device. It may keep current measurement state, calibration settings, and recent trip summaries locally so the app can display its features.

应用在设备上处理 GPS 得出的海拔、坐标、精度、速度、时间戳及计算出的测量值。应用可能在本地保存当前测量状态、校准设置和近期行程摘要，以便提供相应功能。

3. Local Storage / 本地存储

Measurement settings and trip history are stored in the app's private Android storage. The app retains up to 100 recent trip records. The app does not provide an account or cloud-sync feature, and this local data is not uploaded to the developer.

测量设置和行程历史保存在应用的 Android 私有存储中。应用最多保留最近 100 条行程记录。应用没有账号或云同步功能，这些本地数据不会上传给开发者。

4. Advertising and Third-party Services / 广告与第三方服务

The app uses Google Mobile Ads to display a banner in the trip-history area. It also uses Google's User Messaging Platform (UMP) to present consent choices where required. Google and its advertising partners may process information such as advertising identifiers, device information, IP address, app usage, and ad interaction information to provide, measure, personalize, limit, and protect advertising against fraud, subject to applicable settings and law. Advertising data may be shared with Google and relevant advertising demand partners as described by those services.

应用使用 Google Mobile Ads 在行程历史区域展示横幅广告，并使用 Google User Messaging Platform（UMP）在适用地区提供同意选项。Google 及其广告合作伙伴可能根据适用的设置和法律，处理广告标识符、设备信息、IP 地址、应用使用情况和广告互动信息等，用于提供、衡量、个性化、限制及防止广告欺诈。广告数据可能按照相关服务的规则与 Google 及相关广告需求方共享。

You can manage or withdraw applicable advertising consent through the app's “Privacy options” feature. For more information, see Google Privacy Policy.

您可以通过应用中的“隐私选项”管理或撤回适用的广告同意。详情请参阅 Google 隐私权政策。

5. Internet and Network Usage / 网络使用

The app requests Internet access for Google Mobile Ads and the related consent flow. The app contains no developer-operated measurement or trip-data upload endpoint, account service, map service, analytics service, or crash-reporting service.

应用请求网络访问权限，用于 Google Mobile Ads 及相关同意流程。应用不包含开发者运营的测量数据或行程数据上传接口、账号服务、地图服务、分析服务或崩溃上报服务。

6. Data Sharing / 数据共享

The developer does not receive or share your precise GPS location or locally stored trip history. Information processed by Google Mobile Ads and UMP is handled by Google and applicable third parties under their own terms and privacy practices.

开发者不会接收或共享您的精确 GPS 位置或本地保存的行程历史。Google Mobile Ads 和 UMP 处理的信息由 Google 及适用的第三方依据其自身条款和隐私惯例处理。

7. Data Retention and Deletion / 数据保留与删除

Local measurement data remains on the device until it is reset or removed. Recent trip history is retained locally up to the app's 100-record limit. Uninstalling the app or clearing its storage through Android removes the app's local data. Advertising-related retention is governed by Google and its applicable service settings.

本地测量数据会保留在设备上，直到被重置或删除。近期行程历史按照应用最多 100 条的限制保存在本地。卸载应用或通过 Android 清除应用存储空间会删除应用本地数据。广告相关数据的保留期限由 Google 及其适用的服务设置决定。

8. Security / 安全

Local app data is stored in Android app-private storage. Network requests used by Google services are made through their supported secure connections. No method of storage or transmission is completely secure, so we cannot guarantee absolute security.

应用本地数据保存在 Android 应用私有存储中。Google 服务使用的网络请求通过其支持的安全连接发送。任何存储或传输方式都不能保证绝对安全，因此我们无法保证绝对安全性。

9. Children's Privacy / 儿童隐私

Stable Altimeter is not directed to children under the age where parental consent is required by applicable law. We do not knowingly collect personal information directly from children.

Stable Altimeter 不面向适用法律要求取得家长同意年龄以下的儿童。我们不会明知地直接收集儿童的个人信息。

10. User Choices and Permissions / 用户选择与权限

You may deny or revoke location permission in Android settings, but the measurement features that require location will not work. You may pause measurement, reset current measurement values, manage advertising consent through “Privacy options,” or remove all local app data by uninstalling the app or clearing its storage.

您可以在 Android 设置中拒绝或撤回位置权限，但需要位置数据的测量功能将无法使用。您可以暂停测量、重置当前测量值、通过“隐私选项”管理广告同意，或通过卸载应用、清除应用存储空间删除全部本地数据。

11. Changes to this Privacy Policy / 隐私政策变更

We may update this policy when the app's features, data practices, or applicable requirements change. The updated version will be published at this URL with a new “Last Updated” date.

当应用功能、数据处理方式或适用要求发生变化时，我们可能更新本政策。更新版本会发布在此 URL，并标注新的“最后更新”日期。
