雪线(Powtrail)隐私政策

生效日期:2026-08-21 · 适用于 iOS 应用「雪线 / Powtrail」(bundle id: com.yexue.yexueApp)
运营方:广州藕飞丝网络技术有限公司(WioFc)

1. 核心承诺:数据留在你的设备上

雪线没有账号体系,也不运营自己的服务器。你的轨迹、路线、撤退点、设置与所有记录数据全部存储在你的设备本地,我们无法访问、收集或出售这些数据。

2. 会离开设备的仅有两类数据

(a) SOS 求救短信:仅在你主动触发 SOS 时,应用把你当前位置坐标填入短信正文并调出系统短信编辑器,由你确认后发送给预设的紧急联系人。短信经你的运营商网络传输,我们不经手、不留存。

(b) 地图与搜索请求:显示地图瓦片与地点搜索时,应用向第三方地图服务(Mapbox 及备用地理编码服务)发起网络请求,请求中包含地图视野范围或搜索词。适用其隐私政策:Mapbox Privacy Policy。Mapbox SDK 的匿名遥测可在其政策所述途径管理。离线地图包下载后,浏览已缓存区域不产生网络请求。

3. 权限用途

定位(使用期间/始终):显示你在地图上的位置、记录轨迹、导航偏航提醒、把坐标填入 SOS 短信。后台定位仅用于轨迹记录与失联守护倒计时,可随时在系统设置关闭。

4. 数据删除

应用内「隐私中心」可一键清除全部本地数据;卸载应用即彻底删除所有数据。因数据不在我们手中,无需向我们发起删除请求。

5. 儿童

本应用面向具备野外滑雪行为能力的用户,不面向 13 岁以下儿童,我们不会有意收集儿童信息。

6. 政策更新与联系方式

政策更新将发布于本页面并更新生效日期。联系我们:contact@wiofc.com


Powtrail Privacy Policy

Effective date: 2026-08-21 · Applies to the iOS app "Powtrail / 雪线" (bundle id: com.yexue.yexueApp)
Operator: Guangzhou Oufeisi Network Technology Co., Ltd. (WioFc)

1. Core promise: your data stays on your device

Powtrail has no user accounts and operates no servers of its own. Your tracks, routes, retreat points, settings, and all recorded data are stored locally on your device only. We cannot access, collect, or sell this data.

2. Only two kinds of data ever leave your device

(a) SOS messages: only when you actively trigger SOS, the app fills your current coordinates into an SMS and opens the system message composer addressed to your pre-configured emergency contacts — you confirm the send. The message travels over your carrier's network; we neither process nor store it.

(b) Map and search requests: rendering map tiles and searching places sends network requests to third-party map services (Mapbox and fallback geocoding providers), containing the map viewport or your search terms. Their policies apply: Mapbox Privacy Policy. Mapbox SDK anonymous telemetry can be managed as described in their policy. Browsing downloaded offline map regions generates no network requests.

3. Permissions

Location (while-in-use / always): showing your position on the map, recording tracks, off-route alerts during navigation, and filling coordinates into SOS messages. Background location is used solely for track recording and the watchdog timer, and can be disabled in system settings at any time.

4. Data deletion

The in-app Privacy Center wipes all local data with one tap; uninstalling the app deletes everything. Since we never hold your data, no deletion request to us is needed.

5. Children

This app targets users capable of backcountry skiing and is not directed at children under 13. We do not knowingly collect information from children.

6. Updates and contact

Updates will be posted on this page with a revised effective date. Contact: contact@wiofc.com.
