本隐私政策适用于由jianjun zhao（以下简称“我们”）开发并发布的移动应用「轻跑 Pure Pace」（以下简称“本应用”）。我们非常重视你的隐私。本政策说明本应用会处理哪些信息、如何使用与保存这些信息，以及你对此拥有哪些控制权。
一句话概括：轻跑不设账号、不含广告与分析工具，你的位置与运动数据只保存在你自己的手机上，不会上传给我们。
本应用在你的设备本地处理以下信息：
1. 位置信息
在你开始运动后，本应用会通过系统的定位服务持续获取你的经纬度、时间戳、海拔与速度，用于绘制运动轨迹、计算距离与配速，以及在锁屏卡片和通知中显示实时数据。经你授权后，本应用可在后台或锁屏状态下继续获取位置，以保证轨迹不中断。
2. 运动记录
包括运动类型（跑步 / 健走 / 骑行 / 爬山）、开始与结束时间、距离、用时、平均速度、每公里分段配速、估算消耗的卡路里，以及构成轨迹的采样点。
3. 应用设置
包括距离单位（公制 / 英制）、语音播报开关与语言、语音音色、播报前震动开关、显示模式（跟随系统 / 浅色 / 深色）。
以上信息全部保存在你设备上的应用私有存储中：运动记录（含轨迹采样点与每公里分段配速）写入应用本地的数据库（SQLite），应用设置写入系统的键值存储（AsyncStorage）。这些数据不会发送到我们的服务器，我们也不会以任何方式接收、读取或留存。本应用当前没有账号体系，也没有任何后端服务。
| 权限 | 用途 | 拒绝后的影响 |
|---|---|---|
| 使用期间访问位置 | 记录运动轨迹、计算距离与配速 | 无法记录任何运动数据 |
| 始终允许访问位置 | 锁屏或切到后台时继续记录轨迹 | 后台无法记录距离，轨迹会出现断点 |
| 通知 | 显示锁屏运动卡片与每公里提示 | 无法在锁屏查看实时数据，语音播报不受影响 |
| 震动 | 每公里播报前的震动提醒 | 仅失去震动提醒 |
所有权限均可在系统「设置」中随时关闭，关闭后本应用的功能会相应受限，但不会影响已保存的历史记录。
本应用使用了以下由操作系统或平台方提供的组件，它们的行为不受我们控制：
所有运动数据与设置都保存在你的设备上，保存期限由你决定：
由于数据仅存在于你的设备上，我们无法（也没有能力）代为删除或恢复。删除操作不可撤销，请谨慎操作。
本应用不面向 13 周岁以下的儿童，也不会主动收集儿童的任何个人信息。由于本应用不收集任何个人信息，家长可放心让未成年人在陪同下使用。
你的数据保存在应用沙盒内的本地存储中，受操作系统的沙盒机制与应用加密保护。由于数据不会离开设备，也就不存在传输过程被截获的风险。请注意：请为你的设备设置锁屏密码，以防他人物理接触设备后查看你的运动记录。
由于我们不持有你的任何数据，你可以直接通过设备和本应用完全掌控你的信息：随时查看、删除，或导出——在「设置」→「数据管理」→「导出运动记录」中可生成一份包含全部运动记录的备份文件，再通过系统分享面板自行决定发送到哪里。你可以在系统设置中随时撤销位置与通知权限。如对本政策有任何疑问，欢迎通过下方邮箱与我们联系。
我们可能会不时更新本隐私政策。更新后我们会修改本页顶部的“最后更新”日期，重大变更将以应用内提示等显著方式告知你。若未来版本引入账号、云同步、统计分析等功能，我们会在功能上线前更新本政策并重新征求你的同意。

This Privacy Policy applies to the mobile application Pure Pace (the “App”), developed and published by 【Developer Name】 (“we”, “us”). We take your privacy seriously. This policy explains what information the App handles, how it is used and stored, and what control you have over it.
In one sentence: Pure Pace has no accounts, no ads and no analytics — your location and workout data stay on your own phone and are never uploaded to us.
The App processes the following information locally on your device:
1.1 Location data
Once you start a workout, the App continuously reads your latitude, longitude, timestamp, altitude and speed through the system location service, in order to draw your route, compute distance and pace, and show live data on the lock-screen card and notifications. With your permission, the App can keep reading your location in the background or while the screen is locked so your route is not interrupted.
1.2 Workout records
Activity type (run, walk, cycle or hike), start and end time, distance, duration, average speed, per-kilometer splits, estimated calories burned, and the sampled points that make up your route.
1.3 App settings
Distance unit (metric or imperial), voice announcement on/off and language, voice gender, vibration-before-announcement, and display mode (system / light / dark).
All of this is kept in the App’s private storage on your device: workout records (including the sampled route points and per-kilometer splits) in a local database (SQLite), and app settings in the system key-value store (AsyncStorage). None of it is sent to any server of ours, and we cannot and do not receive, read or retain any of it. The App currently has no account system and no backend service of any kind.
| Permission | Purpose | Effect if declined |
|---|---|---|
| Location while using the App | Record your route, compute distance and pace | No workout data can be recorded |
| Location always | Keep recording while the screen is locked or the App is in the background | Distance is not recorded in the background and your route will have gaps |
| Notifications | Show the lock-screen workout card and per-kilometer alerts | No live data on the lock screen; voice announcements still work |
| Vibration | Vibrate before each kilometer announcement | You lose the vibration cue only |
You can revoke any permission at any time in your system Settings. Doing so limits the corresponding features but does not affect workouts already saved.
The App uses the following components provided by the operating system or platform vendor. Their behavior is outside our control:
All workout data and settings are stored on your device, and you decide how long they are kept:
Because the data exists only on your device, we cannot delete or restore it on your behalf. Deletion is permanent and cannot be undone.
The App is not directed to children under 13 and does not knowingly collect any personal information from children. As the App collects no personal information at all, parents may let minors use it under supervision.
Your data is stored in local storage inside the App sandbox, protected by the operating system’s sandboxing and by device encryption. Because the data never leaves your device, there is no transmission that could be intercepted. Please set a lock-screen passcode on your device so that others with physical access cannot view your workout history.
Because we hold none of your data, you have complete control over your information through your device and the App: you can view, delete or export it at any time — exporting creates a backup file of your workout history (Settings → Data Management → Export Workouts) which you then send wherever you choose using the system share sheet. You can revoke location and notification permissions in system Settings at any time. If you have any question about this policy, please contact us at the email below.
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top of this page, and we will notify you of material changes through a prominent in-app notice. If a future version introduces accounts, cloud sync, analytics or similar features, we will update this policy and ask for your consent before those features go live.
