The app does not upload your listening session. Recording a measurement saves sound-level data and statistics—not microphone audio. IMPORTANT Phone microphones are not certified sound-level meters, and readings may vary by device. Calibrate against a trusted instrument when accuracy matters. This app is intended as a practical reference tool and is not a substitute for certified equipment or professional hearing-safety advice.
