Privacy Policy

Effective date: draft for review · Publisher: 191Labs LLC ("we")

DecibelDock is an Android sound toolbox. The short version: the app processes audio on your device, does not include ads or 191Labs analytics, and does not upload your readings or recordings to 191Labs.

Information we collect

191Labs does not collect personal data through DecibelDock for advertising or analytics. The app has no DecibelDock account. We do not operate a DecibelDock server that receives your microphone audio, camera frames, or measurement history.

Information stored on your device

Settings (theme, meter styles, weighting preferences, units, calibration offset, A4 reference, and similar).
Local history lists for tools such as Frequency, Doppler and Distance, plus sound-level session logs you save.
Optional audio recordings you explicitly start and save (off by default).
Preview and Pro entitlement state needed to enforce the free/Pro rules on this device.

This data stays on your device unless you explicitly export or share it. Uninstalling removes app-private storage. If Android backup is enabled, Google may include app data in a device backup under Google's policies; 191Labs cannot read that backup.

Audio, microphone and camera

Microphone audio is processed on the device for metering and tools. Optional recordings are written only when you tap Record and choose to save. Automatic Distance may use temporary camera frames for flash detection; frames are not saved as photos or videos in the product design. Identify classification runs on-device.

Purchases

The optional one-time Pro unlock uses Google Play Billing. Google processes payment details. The app receives purchase confirmation to unlock Pro and to restore purchases. See the Google Privacy Policy.

Permissions (typical)

Microphone	Required for the meter and audio tools.
Camera	Requested only for automatic Distance flash detection.
Notifications / foreground service	Used for screen-off level logging Stop controls and related foreground work you start.
Internet	Not required for measurement. Google Play Billing may add network access for purchases/restores.

Children

DecibelDock is intended for a general audience ages 13 and up and is not directed at children under 13. The app is not designed to collect personal information from children.
