During your interaction with our products, we will further collect nicknames, country codes, language preferences or time zone information from your account.
• Connect to smart devices via Wi-Fi/Bluetooth: Wi-Fi information (SSID, BSSID, Wi-Fi password), device ID, and MAC address for Bluetooth on the device.

(2) Mobile device information

When you interact with our products, in order to ensure your normal use of our services, improve and optimize our service experience and ensure the security of your account, we will automatically collect mobile device information, including mobile device model, login IP address, wireless connection information, operating system type and version, app version number, push notification identifier, log file and mobile network information.

2. Information collected based on the additional functions provided

In order to provide you with more convenient and better products and/or services and strive to improve your experience, we will collect and use your personal information in the following additional services provided to you. If you don't provide such information, it won't affect your use of the basic services of TERRAINA App, but you may not be able to access to additional services, including:

(1) User feedback

When you accept our service and submit feedback and suggestions related to the service to us, we will collect your email address, mobile phone number and feedback information (uploaded pictures or videos), as well as the submitted problem log, all of which will be used by us to timely deal with your app problems and smart device failures, and to contact you.

(2) Additional services based on location information:

When you enable the location function of your mobile device through system authorization and use location-based services, we will collect and use your location information to enable you use TERRAINA App to pair network with smart devices. The reason of obtaining location permission in "Add Device": Enter "Add Device" and perform Bluetooth scanning based on the function of searching nearby devices. At this time, we will be authorized to perform Bluetooth communication. Because we need to collect your location information during Bluetooth scanning, you need to turn on Bluetooth and request location to add a device, otherwise your "Add Device" function will not be enabled. You can disable the location service in the mobile device system to stop our collection of your location information.

(3) Additional services based on camera/webcam:

You can use this function to scan code after enabling the camera/webcam permissions, so as to add the device you purchased and shoot a video. Please be aware that even if you have agreed to enable the camera/webcam, we will only obtain information when you take the initiative to scan the code and shoot with the camera/webcam. The code scanning function can be used to collect the information of light sensor and judge whether it is necessary to show the flash function according to the data of light sensor.

(4) Additional services for permitting and uploading pictures/videos based on photo albums (photo gallery/video library):

You can use this function to upload your photos/pictures/videos after enabling the photo album permissions, so as to realize the function of reporting problems in the use of equipment and providing proof. When you report a problem in the use of the equipment, we will locate your problem through the photos/pictures you uploaded.

(5) Additional services based on storage permission:

We apply for this permission from you to ensure the stable operation of the client end. After you enable our permission to read/write your device storage, we will read or write the necessary information of pictures, files and crash log information from or into your device storage space, so as to provide you with the function of publishing information or recording crash log information locally.

(6) Additional functions based on message notification permission:

We apply for this permission from you to send you the notifications about products or services, especially when we need to send you an alarm after you purchase relevant services, so that you can grasp the real-time situation.

(7) Related additional services based on Bluetooth technology:

You can use the Bluetooth function after enabling Bluetooth permission, including device control, device status acquisition, device discovery, and device network distribution. In these functions, we will communicate with terminal devices through Bluetooth. Please be aware that even if you have agreed to enable the Bluetooth permission, we will only use Bluetooth for communication in these scenarios: display equipment status on the home page and the device panel; control the device on the home page and the devoice panel; device discovery and device network distribution on the home page and the Add Equipment page.

You understand and agree that, for the above-mentioned additional services, you need to enable the access permissions to your location information (geographical location), webcam (camera), photo album (photo gallery), microphone (voice), and internal and external memory in your device, so as to collect and use the information involved in these permissions. You can check the status of above permissions item by item in your device settings, and you can decide whether to enable such permissions.

Please be aware that, by enabling any permission, you authorize us to collect and use relevant personal information to provide you with corresponding services, and by enabling any permission, you cancel the authorization, we will no longer continue to collect and use relevant personal information based on the corresponding permission, and we will not be able to provide you with the services corresponding to this permission. However, your decision to enable the permission will not affect the previous information collection and use based on your authorization.

3. Non-personally identifiable information

We may also collect other information that cannot be directly or indirectly used to identify a specific individual and is not personal information under applicable local laws. Such information is referred to as non-personal information. We may collect, use, transfer and disclose non-personal information, which may include:

• Statistical data generated during your use of specific services (such as anonymous device-related information, daily events, page access events, page access duration events, and session events).
• Network monitoring data (such as request duration, number of requests and error requests, etc.).
• Application crash events (such as logs automatically generated after application crash, etc.).

Such information is collected for the purpose of improving the service we provide to you. The type and quantity of information we collect will depend on the way you use our products and/or services.

We will aggregate such information to help us provide you with more useful information, and realize which parts of our website, product or service you are most interested in. For example, we may only need to know the number of active users in a day, and do not need to know who are active in that day, so aggregated data is sufficient for us to make a statistical analysis. We will try our best to separate your personal information from non-personal information, and ensure that these two types of information are used separately. If we use non-personal information in combination with personal information, such information will be treated as personal information during the combination.
