Once you start using this application, you agree to our collection and use of your relevant information in accordance with this policy.

1. Information we collect

In order to provide and optimize the core functionalities of this application (Bluetooth device connection, host control, network status acquisition, device discovery, etc.), we may collect the following types of personal information:

Bluetooth permission
Purpose: To scan, connect to, and control the smart host device you have purchased (such as setting parameters, reading status, issuing commands, etc.). Bluetooth is the core method of communication between this application and the hardware device.
Information types: Device broadcast information, Bluetooth name, signal strength (RSSI), device pairing status, connection log.

Network access
Purpose: To check the network connection status and ensure that the application can access the Internet normally (e.g., check for firmware updates, report device exception logs, and obtain cloud configuration information).
Information types: Wi-Fi connection status, IP address, network type (cellular/Wi-Fi).

Location permission
Purpose of use:

• On the Android system, scanning for Bluetooth devices requires obtaining "Coarse Location" or "Precise Location" permission (as required by the system).
• Used for location-based device search optimization (e.g., finding nearby devices).

We will not collect or upload your precise geographic location for any other purposes.
Information type: Only the positioning switch status required at the system level; we do not actively collect location information such as GPS latitude and longitude.

II. How we use information

• Realize Bluetooth communication and control between devices.
• Optimize the speed of device discovery and connection stability.
• Solve technical problems and improve application performance.
• Comply with legal and regulatory requirements or respond to lawful requests from law enforcement agencies.

III. Information Storage and Protection

Storage location: All data is stored exclusively on your local device. We will not upload your personal information to any server unless you actively participate in firmware upgrades or send feedback logs.

Security measures: We employ industry-standard encryption measures, such as TLS at the transport layer, to safeguard Bluetooth commands and data during network communication.

Retention period: Local data will be cleared after you uninstall the app or reset your device.

IV. Information Sharing and Disclosure

No sharing with third parties: We will not sell, exchange, or rent your personal information to any third parties.

Legal requirements: We may disclose your information under legal and regulatory provisions or mandatory requirements imposed by government authorities.
