# Privacy Policy — WiFi Diagnostic
**Last updated:** June 5, 2026
This Privacy Policy explains how the **WiFi Diagnostic** app ("the app", "we", "us") handles information when you use it. Please read it carefully.
---
## Summary (plain English)
- The app analyzes your **local WiFi and network** to show you diagnostics.
- We do **not** collect, store, or sell your personal data on our own servers.
- We use **Google AdMob** to show ads and **Google Firebase** for anonymous analytics and crash reports.
- WiFi passwords you type for the QR generator **never leave your device**.
- Network scans (ping, speed test, device scan) run **locally** or against public test servers.

## Information the App Accesses
### 1. Location Permission
Android **requires** the location permission to read WiFi network names (SSID) and to scan for nearby WiFi networks. This is an Android operating-system rule, not our choice.
- We use location access **only** to read WiFi network information.
- We do **not** track, store, or transmit your physical location.
- We do **not** use GPS to follow your movements.
### 2. Network Information
The app reads information about the network you are connected to, such as signal strength, IP address, gateway, link speed, and nearby network names. This is processed **on your device** to display diagnostics. It is not uploaded to us.
### 3. Device Scan (LAN / Camera Finder)
When you run a network device scan, the app probes devices on your **local network** to identify them. This happens entirely on your local network and is not sent to us.
### 4. WiFi QR Generator
If you generate a WiFi QR code, the network name and password you enter are used **only on your device** to create the QR image. This data is never transmitted or stored by us.
### 5. Speed Test
The speed test downloads and uploads data to **Cloudflare's public speed-test servers** (`speed.cloudflare.com`) to measure your connection. Your ISP name and approximate city may be retrieved from a public IP-information service (`ip-api.com`) to display your provider. We do not store this.

## Third-Party Services
The app uses the following third-party services, each with its own privacy policy:
### Google AdMob (Advertising)
We show ads via Google AdMob. AdMob may collect and use data as described in Google's policy. For users in the EU/EEA/UK, we present a **consent form** (via Google's User Messaging Platform) before serving personalized ads, as required by GDPR.

### Google Firebase (Analytics & Crash Reporting)
We use Firebase Analytics (anonymous usage statistics) and Firebase Crashlytics (crash reports) to improve the app. This data is aggregated and anonymous.
- Firebase Privacy: https://firebase.google.com/support/privacy
- Push Notifications (Firebase Cloud Messaging): We may send you push
notifications about app updates or new features. You can disable these
anytime in your device settings. In-app messages may also be shown via
Firebase In-App Messaging.

- We do **not** collect your name, email, phone number, or contacts.
- We do **not** store your WiFi passwords.
