This App is primarily used to connect to your devices, read device operational information, and manage this information through your personal account. Personal data refers to any information relating to an identified or identifiable natural person, which includes, in particular: name, address data, IP address, location coordinates, phone number, or email address. We will not provide, sell, rent, share, or trade your personal login information to any third party without your explicit consent.

To provide you with full services, we may need to request the following device permissions. You have the right to disable these permissions at any time in your device settings. 1. Location Information To discover nearby devices via Wi-Fi for initial pairing, we require your authorization to access your precise location information. You can disable this permission at any time through your mobile device's system settings. Please note that refusing to provide location information may prevent the device discovery feature from working. Aside from device discovery, the App's core functionalities do not rely on continuously obtaining your location. 2. Camera To provide the feature of adding devices by scanning a QR code, we may request access to and use of your camera permission after you explicitly consent and actively initiate the scanning operation.

Denying this permission will only disable the QR code scanning feature for adding devices but will not affect your use of the App through other methods (e.g., manual input).
