PRIVACY FIRST
Your microphone is used only to measure sound levels in real time. Audio is never recorded, saved, or transmitted, and the app needs no account to work.

PLEASE NOTE
Sound Level Meter: dB Pro uses your phone's built-in microphone, which is not a laboratory-calibrated instrument. Readings are approximate and intended for general, informational, and reference use only, not for professional, occupational-safety, legal, or medical purposes. Microphone sensitivity varies between phone models; use the built-in calibration setting to align readings with a trusted reference meter.
