History and privacy

DecibelDock keeps tool history on your phone. Audio processing stays on the device. Optional recordings are off by default, and clips never upload themselves.

Automatic local history

Doppler, Distance and Frequency can auto-fill local history lists with numbers and times. You can delete one entry or clear all. History stays on the phone.

Screen-off level logging continues a session you started, with a visible Stop notification. It does not restart on boot.

Optional recordings

Recording is opt-in and off by default. You explicitly start, stop, and choose Save or Discard. Clips stay in private app storage with playback, export and delete. No clip is written just because you tapped Start on the meter.

Privacy stance

Product rules: no ads, no accounts, no 191Labs collection of readings, audio or camera images. Camera analysis for automatic Distance uses temporary frames, not saved photos. The optional one-time Pro purchase uses Google Play Billing.
