1. Audio Processing

GT TUNER PRO requires access to your device's microphone to detect pitch. All audio processing is performed locally in your web browser using the Web Audio API. We do not record, transmit, or store your audio data on any server.

2. Analytics and Data Collection

We collect basic, anonymized telemetry (such as browser type and page views) to ensure the stability of our application. No personally identifiable information is tracked.

3. Local Storage

We use your browser's local storage to remember your tuning preferences, such as selected input device and A4 calibration reference. This data never leaves your device.
