No user data, telemetry, audio, or personal information is transmitted.<br>✅ All audio processing is done LOCALLY on the device.<br>✅ No audio is recorded, stored, or transmitted.<br>✅ No audio data is sent to external servers, third parties, or the internet.<br>✅ The microphone is only accessed while the measurement is active on the screen.<br>✅ The app does not require a user account, login, or internet connection.<br>✅ The RECORD_AUDIO permission is used solely to read the sound pressure level (SPL).<br>✅ The audio signal is processed in RAM in real time and discarded immediately after calculation - it is never saved.
