本 App 不收集、不存储、不传输任何个人数据。它不发起任何外部网络请求。
不联网
格物不向任何服务器发送数据，也不从任何服务器获取数据。全部厂商名录、机型规格与 识别规则都随 App 一起打包在本地。没有分析 SDK，没有崩溃统计，没有广告，没有账号系统。
位置权限
iOS 规定：App 必须持有定位授权，才被允许读取当前连接 Wi-Fi 的名称与 BSSID
（系统接口 NEHotspotNetwork）。这是平台限制，不是本 App 的选择。
- App 不请求实际坐标，不调用任何获取位置的接口
- 不存储位置数据
- 不传输任何数据
- 权限仅在你于「网络」页主动点击说明卡片后才请求；冷启动不请求任何权限
本地网络权限
用于识别路由器型号。App 向你的网关发送一次未认证的 HTTP GET 请求，读取响应头与页面标题。
- 不尝试登录，不发送任何凭据
- 不扫描端口，仅使用 80 与 443
- 不访问网关以外的任何地址
- 单次探测最多 5 个请求，6 秒内结束
- 证书校验从不关闭
本机存储的数据
你的网络识别记录（网络名称、BSSID、识别结果）仅保存在你的设备本地， 使用完全文件保护存储，设备锁屏后不可读。这些数据不会离开你的设备，可随时在 App 的「设置」页一键清空。

Privacy Policy
Whence · Last updated: August 9, 2026
This app collects, stores, and transmits no personal data. It makes no external network requests.
No network activity
Whence sends no data to any server and retrieves no data from any server. All manufacturer records, model specifications, and identification rules ship inside the app. There are no analytics SDKs, no crash reporting, no advertising, and no user accounts.
Location permission
iOS requires an app to hold location authorization before it may read the name and BSSID of
the connected Wi-Fi network (via the system NEHotspotNetwork API). This is a
platform requirement, not a choice this app made.
- The app never requests actual coordinates and calls no location-retrieval API
- It never stores location data
- It never transmits anything
- Permission is requested only after you tap an explanatory card on the Network tab; nothing is requested at launch
Local network permission
Used to identify your router's model. The app sends a single unauthenticated HTTP GET to your gateway and reads the response headers and page title.
- Never attempts to log in; never sends credentials
- Never scans ports; uses only ports 80 and 443
- Never contacts any address other than the gateway
- At most 5 requests per probe, finished within 6 seconds
- Certificate validation is never disabled
Data stored on your device
Your network identification records (network name, BSSID, identification result) are stored only on your device, with complete file protection, and are unreadable while the device is locked. This data never leaves your device and can be cleared at any time from the app's Settings tab.
Children
This app is not directed at children and collects no age-related information.
Changes to this policy
If this policy changes, the date at the top of this page will be updated. Any change involving data collection will be stated explicitly in the app's release notes.
