(5) Data Collection in Application Background and Silent State
We understand your concerns about the collection of personal information by applications running in the background or in a silent state. Here, we specifically state:
Some third-party SDKs integrated into our application (especially Kuaishou Alliance Advertising SDK) may collect device information such as WiFi lists (including SSID, BSSID, etc.) when the application is running in the background or in a silent state.
The purposes of this data collection mainly include:
- Advertising delivery optimization: Helping to provide more accurate advertising delivery services through this information
- Anti-cheating detection: Used to identify potential fraudulent behavior and ensure the fair operation of the advertising system
- Security maintenance: Helping SDK providers maintain the security and stability of their services
Data collection frequency: We have requested various SDK service providers (especially Kuaishou Alliance) to control the data collection frequency to the necessary minimum, generally once every 30-60 minutes.
Your control:
- You can disable the application's access to WiFi at any time through the system settings of the device (such as "Application Permission Management" or "Application Management" in the Android system)
- You can also completely exit the application (rather than just switching the application to the background) to prevent such data collection
We promise to continuously monitor and optimize the data collection behavior of third-party SDKs to ensure compliance with the principle of necessity and relevant legal and regulatory requirements.

IV. How We Protect Your Personal Information
We have adopted various security technologies and protective measures that meet industry standards to protect your personal information from unauthorized access, use, or leakage. For example, when you exchange data with knock Dream Technology cloud server (purchased from domestic Yingguang Cloud), we use HTTPS, SSL, AES, and other technologies to ensure data security and confidentiality; we will strictly follow domestic and international security standards to build a security system and implement cutting-edge, mainstream security technologies to prevent unauthorized access, use, or leakage of users' personal information. We have established a comprehensive security defense system, which can proactively intercept attacks when we are subjected to external network attacks or virus infections.
We have established a sound data security management system, including classifying and encrypting user information, dividing data access permissions; formulating internal data management systems and operating procedures, with strict process requirements for data acquisition, use, and destruction to avoid illegal use of your privacy data; we will regularly conduct security and privacy protection training to raise employees' awareness of personal information protection. However, you should understand that due to technical limitations and various malicious means that may exist, even with our best efforts to strengthen security measures, it is impossible to guarantee 100% information security at all times. Information leakage may occur due to factors beyond our control. If unfortunately, a personal information security incident occurs, we will promptly inform you of the basic situation and possible impact of the security incident, the emergency response we have taken or will take, and other relevant disposal measures and remedies through in-site messages or your reserved contact information as required by laws and regulations. If it is difficult to inform each personal information subject individually, we will take reasonable and effective ways to publish announcements and proactively report the handling of personal information security incidents to relevant regulatory authorities.
If you find that your personal information has been leaked, please contact us immediately through the contact information listed in this Privacy Policy so that we can take corresponding measures in a timely manner.
