Privacy

Short version: this app sends nothing about you anywhere.

Microphone access

The app asks for microphone permission so it can detect the pitch of the string you're playing. The audio stream is processed entirely in your browser — none of it is sent to any server. The processing happens inside JavaScript running on your device. When you tap Stop tuning the microphone is released and the browser stops capturing audio.

Tracking

None. No analytics. No advertising. No cookies. No third-party scripts. The page loads only what it needs to run the tuner — HTML, CSS, JS, icons, manifest, service worker.

Data we store

Nothing on our side. Your browser may cache the page assets locally for offline use (service worker) and remember your microphone-permission decision (browser-level setting). That's it.
