Privacy Policy

Last updated: July 4, 2026

ClearWifi is a lightweight WiFi analysis and speed test app. This policy explains what data the app accesses and how it is handled.

No Personal Data Collection

ClearWifi does not collect, store, or transmit any personal information. There are no accounts, no analytics SDKs, no advertising networks, and no third-party authentication services in the app.

Permissions

ClearWifi requests the following Android permissions:

Location (“precise location”) — Required by Android for WiFi scanning. Your location is never collected, stored, or transmitted by ClearWifi. While analyzer screens are open, the app requests high-accuracy location updates (which may briefly activate GPS) solely to increase WiFi scan frequency; the resulting fixes are discarded. This permission is requested only when you choose to view nearby WiFi networks; the speed test and current-network signal meter work without it.
WiFi & Network State — Used to read your current WiFi connection (SSID, signal strength, channel) and to detect whether a network connection is available for speed testing.
Internet — Required for the speed test to communicate with M-Lab servers.

WiFi Scanning Data

When you grant location permission, ClearWifi reads nearby WiFi network information (SSID, BSSID, signal strength, channel, and security type) from Android’s WiFi subsystem. This data is displayed on-screen and stored only in your device’s local history; it is never transmitted anywhere.

Speed Test Data

Speed tests are powered by M-Lab (Measurement Lab), an open-source, non-profit measurement platform backed by Google, Cloudflare, Mozilla, and the Internet Society. When you run a speed test:

Your device connects directly to an M-Lab server over secure WebSocket (WSS).
M-Lab’s platform openly publishes all test data, including your client IP address and test results, for internet research purposes. This is how M-Lab operates and is documented at measurementlab.net/data.
ClearWifi does not have access to, nor does it store, the data M-Lab publishes.

Local Storage

Speed test results and WiFi signal snapshots may be stored locally on your device using a local database (Room). This data never leaves your device and is used solely to show your history within the app. You can clear it at any time by clearing the app’s storage in Android Settings.

No Backend Servers

ClearWifi does not operate any backend servers. All functionality runs entirely on your device, with the exception of speed tests which communicate with M-Lab’s open infrastructure.

Children’s Privacy

ClearWifi does not knowingly collect personal information from children under 13. The app does not collect personal information from anyone.

Changes to This Policy

If this privacy policy changes, the updated version will be posted here. Continued use of the app after changes constitutes acceptance.
