IMPORTANT INFORMATION

ClearSine is an audio utility and does not detect water, diagnose damage, repair hardware, or guarantee water removal. Do not hold the speaker close to your ears while loud tones are playing. If your device has significant water exposure or physical damage, follow the manufacturer’s instructions or contact a qualified repair technician.

Microphone access is requested only when you start the dB sound meter. Audio is processed in real time on your device and is not recorded, stored, or uploaded.
