Wifi Signal Map & Speedtest ("we", "our", or "the app", also known as Wifi Signal) is committed to protecting your privacy. This policy explains what data we access, how we use it, and your rights as a user.
WHO THIS APP IS FOR
Wifi Signal is a technical WiFi analysis tool intended for users aged 18 and over. This app is not directed at children. We do not knowingly collect personal information from anyone under the age of 13. If we become aware that a child under 13 has provided personal data, we will take steps to delete it immediately.
DATA WE DO NOT COLLECT (FROM OUR OWN SERVERS)
Wifi Signal does not collect, store, transmit, or sell any personal data to our own servers or to third-party marketing platforms beyond what is described in this policy. We do not have a backend server. We do not run our own analytics SDKs.
DATA STORED LOCALLY ON YOUR DEVICE
All heatmap projects, measurement points, walls, access points, text labels, and app settings are stored exclusively in a local Room database on your device. This data never leaves your device through our systems. Uninstalling the app will permanently delete all locally stored data.
ADVERTISING (GOOGLE ADMOB)
This app uses Google AdMob to display advertisements. AdMob may collect and use certain data to provide personalized ads, including your device's advertising ID, IP address, and app usage information. This data collection is governed by Google's Privacy Policy (policies.google.com/privacy).
You can opt out of personalized advertising at any time through your device settings: Settings → Google → Ads → Opt out of Ads Personalization (Android). We do not control the data practices of Google AdMob and are not responsible for their data collection activities.
PERMISSIONS AND WHY WE NEED THEM
ACCESS_FINE_LOCATION — Android system requirement to perform WiFi scanning (SSID/BSSID discovery). Without this permission, Android does not allow any app to scan nearby WiFi networks. WifiSignal processes location-related data locally and does not record, store, or share your physical coordinates.
NEARBY_WIFI_DEVICES (Android 13+) — Alternative permission on Android 13 and above that allows WiFi scanning without requiring full location access.
ACCESS_WIFI_STATE / CHANGE_WIFI_STATE — To read current WiFi connection information such as signal strength, channel, frequency, and link speed.
READ_MEDIA_IMAGES / READ_EXTERNAL_STORAGE — Only used when you explicitly choose a floorplan image from your gallery. The app reads the image you select and copies it to local app storage for use in heatmap projects.
INTERNET — Used for: (a) Speed Test via Cloudflare, (b) Ping Monitor, (c) IP Info via ipify.org and ipapi.co, and (d) displaying advertisements via Google AdMob.
THIRD-PARTY SERVICES
Wifi Signal communicates with the following third-party services:
Cloudflare Speed Test (speed.cloudflare.com) — Used solely for speed test measurement.
ipify.org (api.ipify.org) — Used to display your public IP address on request.
ipapi.co — Used to display your ISP/provider name on request.
Google AdMob (admob.google.com) — Used to display in-app advertisements. Please review Google's Privacy Policy at policies.google.com/privacy.
DATA CONTROL AND DELETION
You have full control over your data:
To delete all heatmap projects and measurement data: use the "Delete All Data" button in Settings → About, or go to Settings → Apps → WifiSignal → Clear Data on your device.
To delete all app data permanently: uninstall the app.
For data deletion assistance or inquiries: contact us at rzxdeveloper@gmail.com and we will respond within 30 days.
SECURITY
Since all app data is stored locally on your device, the security of your data depends on your device's own security measures (screen lock, encryption, etc.). We do not have access to your locally stored data.
CHANGES TO THIS POLICY
We may update this Privacy Policy from time to time. Changes will be communicated through app update release notes. Continued use of the app after changes constitutes acceptance of the updated policy.
