Privacy policy

November 4, 2026 version

Scope

This policy describes how LED Banner, package com.lumaflow.led, provided by Arcadia Lab, handles data.

Camera and microphone

The camera reads sign QR codes when you start a scan. The microphone is used only when you enable beat mode. Analysis runs on the device without saving or sending audio.

On-device data

Messages, templates, preferences, and selected sign images stay on your device. This version works without an account, has no ads, and does not send this data to Arcadia Lab.

Sharing

When you share a QR code, link, or image, you choose the destination. The shared content may include the message and sign settings.

Permissions and deletion

You can revoke permissions in Android settings, delete signs in the app, or erase app data by clearing its storage. Exported files and shared copies may remain outside the app.
