迷雾轨迹 Trailfog
隐私政策
「迷雾轨迹 Trailfog」(以下简称"本 App")由个人开发者开发和维护。我们非常重视你的隐私,本政策说明本 App 会收集哪些数据、如何使用、以及如何存储。
我们收集什么数据
本 App 的核心功能是记录你走过的真实路线,因此需要访问你的精确位置信息(GPS 经纬度、海拔、速度、航向及对应时间戳)。除位置数据外,本 App 不收集你的姓名、联系方式、照片、通讯录等任何个人身份信息,也不要求注册账号或登录。
数据如何存储
- 默认情况下,所有轨迹数据只保存在你的设备本地,不会以任何形式发送到开发者的服务器 —— 本 App 没有自己的后端服务器。
- 如果你在「云同步」页主动打开 iCloud 同步开关,数据会通过 Apple 的 CloudKit 存入你自己 Apple 账号下的私有数据库(Private Database),该数据经 Apple 加密,开发者本人无法访问、也无法看到其中内容。
- 同步开关默认关闭,你可以随时关闭。
后台定位权限
如果你选择授予"始终允许"定位权限,本 App 会在你切换到其他 App 或锁屏后继续在后台记录轨迹,以保证一段行程的完整性。这项权限完全由你自主选择,App 内会在系统弹窗前先做说明;你也可以随时在系统「设置」中改为"使用期间"或关闭。
第三方共享与分析
本 App 不包含任何第三方广告 SDK、数据分析 SDK 或统计工具,不会将你的位置数据出售、出租或以任何形式共享给第三方或用于广告投放。
地图服务
本 App 使用 Apple 原生地图(MapKit)展示轨迹与底图,遵循 Apple 地图服务自身的隐私条款。
数据删除
你可以在「回放」页删除单条历史记录;如需清空全部本机数据,目前可通过删除并重新安装 App 实现。如果你开启过 iCloud 同步,关闭同步开关后也可以在 iOS「设置 → 你的 Apple 账号 → iCloud → 管理账户存储空间」中移除对应的 App 数据。
儿童隐私
本 App 不面向 13 周岁以下儿童设计,也不会有意收集儿童的个人信息。
政策更新
如本政策有重大变更,我们会更新本页面顶部的"最后更新"日期。建议你不定期查看本页面。

Privacy Policy
Trailfog ("the App") is developed and maintained by an independent developer. This policy explains what data the App collects, how it is used, and how it is stored.
What we collect
The App's core function is recording the real-world routes you walk, so it requires access to your precise location (GPS coordinates, altitude, speed, heading, and timestamps). Beyond location data, the App does not collect your name, contact details, photos, contacts, or any other personally identifying information. No account or sign-in is required.
How data is stored
- By default, all track data stays on your device only. It is never sent to any developer-owned server — the App has no backend server of its own.
- If you explicitly enable the iCloud sync toggle in the "云同步" tab, your data is stored via Apple's CloudKit in your own Apple ID's private database, encrypted by Apple. The developer cannot access or view this data.
- Sync is off by default and can be turned off at any time.
Background location
If you grant "Always" location permission, the App continues recording your route in the background after you switch apps or lock your phone, so a session stays complete. This is entirely your choice — the App shows an explanation before the system prompt, and you can change it to "While Using" or off at any time in iOS Settings.
Third-party sharing & analytics
The App contains no third-party advertising SDKs, analytics SDKs, or tracking tools. Your location data is never sold, rented, or shared with any third party, and is never used for advertising.
Map services
The App uses Apple's native MapKit to render maps and routes, subject to Apple's own map service privacy terms.
Data deletion
You can delete individual sessions from the "回放" (Replay) tab. To remove all local data, currently the supported way is deleting and reinstalling the App. If you previously enabled iCloud sync, you can also remove the App's iCloud data via iOS Settings → your Apple ID → iCloud → Manage Account Storage.
Children's privacy
The App is not directed at children under 13 and does not knowingly collect information from children.
Changes to this policy
If this policy changes materially, we will update the "Last updated" date at the top of this page.
