Your data stays on your Mac. Always.

No personal data collection

WiFi Lens does not collect, store, or transmit any personally identifiable information. The app contains no user accounts, no analytics SDKs, no ad networks, and no telemetry frameworks. We operate no backend servers to receive your data — because we have no interest in having it.

Why we request permissions

Wi‑Fi — Core function: scanning and analyzing nearby wireless networks.

Bluetooth — Optional: discover nearby Bluetooth devices for coexistence analysis. This is off by default and runs entirely on your device.

Location — macOS requires this for any app that reads Wi‑Fi network names (SSID). WiFi Lens never accesses your GPS coordinates or records your location.

Local Network — Only used if you turn on the MCP server in Settings. It listens on your own computer (127.0.0.1) so local tools like Claude Desktop can read Wi‑Fi data. Off by default — nothing leaves your Mac.

Everything stays on your machine

All Wi‑Fi scan results, Bluetooth discovery data, channel recommendations, and regulatory region detection run entirely on-device. No scan data is ever uploaded to a remote server.

Crash reports and diagnostic logs are written to files on your own disk. Nothing is transmitted unless you explicitly choose to share it.

The MCP server binds to 127.0.0.1 (localhost only). No scan data leaves your machine through MCP unless you deliberately route it elsewhere.

Editions

WiFi Lens is offered as a free open-source edition (GitHub) and a paid Pro edition (Mac App Store). Both editions run entirely on your Mac and process scan data locally. For updates: the App Store edition uses Apple's built-in update mechanism and never contacts a third-party server; the direct-download edition uses the Sparkle framework, which fetches only a version descriptor (appcast) from GitHub — no personal data, analytics, or diagnostics are transmitted.

Website analytics

This website uses Cloudflare Web Analytics to measure aggregate page views and performance. Cloudflare Web Analytics does not use cookies, localStorage, or fingerprinting for analytics. It is separate from the WiFi Lens app: no Wi‑Fi scan data, network names, diagnostics, or app activity is sent to this website analytics service.
