Permissions

Bluetooth Permission-
Required to discover, pair, connect, and communicate with compatible Bluetooth devices.

Microphone Permission-
Used only for the optional Voice Controller feature. Audio is never stored or shared by the app.

Internet Permission-
Used to support app services such as advertisements and analytics.

Privacy-
Arduino BT Controller does not require user registration or account creation. Bluetooth communication occurs only with devices that you explicitly select and connect.

Note-
Arduino BT Controller is designed to work with compatible Bluetooth-enabled hardware. Your Arduino, ESP32, ESP8266, or other supported device must be running compatible firmware to communicate with the app successfully.
