Privacy Policy for Joy Tune

This Privacy Policy is issued by Ningbo Ketterose Electrical Appliances Co., Ltd. (Chinese Name: 宁波凯特罗斯电器有限公司) (Registered Address: Xia'an Village, Zhouxiang Town, Cixi City, Zhejiang Province, China).

We understand the importance of your privacy. Therefore, we have established this Privacy Policy (hereinafter referred to as the "Policy") to clarify how we collect, use, protect, and share your personal information. Please read this Policy carefully before using the Application. By using the Application, you indicate that you have fully understood and agreed to all the terms of this Policy.

1. Information Collection

We may collect the following information or request certain permissions:

• Device Information:

  (1) To identify your device ID, prevent malicious programs and fraud, enhance service security, and ensure the quality and efficiency of operations, we will collect your device information (including IMEI, device serial number, OAID, MEID, Android ID, IMSI, GUID, MAC address, SIM card serial number, etc.), information about installed applications, or information about running processes.
  (2) When using the application, to adapt to your device status, we will call the device's gravity and accelerometer sensor information to identify the landscape or portrait status of your device.
  (3) When you share or receive shared information, we need to locally access your clipboard to read content such as passwords, sharing codes, and links to enable features or services like jumping, sharing, and activity linkage.
  (4) To achieve cleaning and acceleration functions, we will request storage permissions to access external storage information (SD card data) to check the phone's CPU, memory, and SD card status.

• Usage Data: Including operation logs (requiring your explicit authorization) and application usage duration.
• Location Information: With your consent, we may collect your location information via GPS, Bluetooth, and other technologies to provide location-based services (such as syncing local weather information to Bluetooth devices).
• Storage Permissions: Allow the application to access files and folders on the device for data reading and storage. This is crucial for syncing device data to the phone or cloud and restoring data from the phone or cloud to the device.
• Camera Permissions: Allow the application to use the device's camera function. This may be used for QR code recognition in Bluetooth device applications, enabling users to connect via device information identified from QR codes, which requires camera permissions.
• Network Permissions: Allow the application to communicate over the network, including sending and receiving data. This is crucial for the application to obtain data from the cloud, update device firmware, or perform remote control operations.
• Read Phone Contact Information and Call Records: Some devices that support calling functions need to display phone contact information and call records to facilitate answering and making calls on the device.
• Push Notifications: To ensure that devices can receive broadcast notifications from the client when the application is closed or running in the background, the application must use the auto-start capability. There will be a certain frequency of broadcasts sent by the system to wake up the application for auto-start or associated start behaviors, which is necessary for the functionality and services provided. When you open content-related push messages, after obtaining your explicit consent, the relevant content will be opened. Without your consent, there will be no associated starts.

2. Use of Information

• Service Provision: To provide and improve application features.
• Security and Maintenance: To detect, prevent, and respond to fraud, security risks, and illegal activities.

3. Information Security

• Encryption Storage: We use reasonable security technologies and procedures to protect your personal information.
• Access Control: We strictly limit internal employee access to your personal information.
• Third-party Services: If we collaborate with third parties, we will require them to comply with the same data protection standards.
