1. What information we collect

This App does not have a user account system and will not actively collect personally identifiable information. Only when you use hardware-related functions and exception reporting, partial device?related information will be generated. All information is only used to ensure normal App operation, BLE peripheral connection, BLE-OTA firmware upgrade and program issue troubleshooting.

1.1 BLE Bluetooth permissions and related information

To scan, discover and connect BLE Bluetooth hardware devices, and perform device OTA firmware upgrade, the App requires you to grant Bluetooth permission:

After authorization, the App scans surrounding BLE broadcast packets and obtains BLE device MAC address, hardware identifier and firmware version number.

Such information is only used for: discovering your hardware device, establishing Bluetooth communication, verifying firmware version, delivering OTA upgrade packages, monitoring upgrade progress and troubleshooting upgrade failures.

Background continuous Bluetooth scanning will not be performed. Scanning only occurs when you actively enable Bluetooth?related functions. No personal identity information of your mobile phone will be uploaded or stored.

If you deny Bluetooth permission, Bluetooth connection and device OTA firmware upgrade functions will be unavailable.
