In order to ensure the availability of Lumon's basic functions, continuous optimization of product experience and platform operation security, we will collect multiple types of data related to your usage behavior in compliance with laws and regulations and with your authorization. Depending on the specific type of service you use, the scope of information collected may vary, including the following three categories:

We always follow the principle of "legal, legitimate, and necessary" and use the collected personal information only in compliance with laws and regulations and with user authorization. This section will explain the specific purposes for which we collect this information and ensure that the entire use process has clear security boundaries and user controllability.

We use the registration information you provide to create and manage your Lumon account, complete identity authentication, and protect account ownership. When you use the various functions of Lumon, we complete the upload, posting, saving and other function execution processes according to your operating instructions. For example, when you initiate a video call or post a dynamic, we will call the necessary device permissions as needed and process the corresponding data to implement the service. At the same time, in order to ensure your smooth use, we will also communicate with you through the contact information you provide (such as email) to respond to your feedback, suggestions, complaints or technical support requests.

We continue to optimize the user experience of Lumon, and we will also use anonymized or de-identified information data for function and interface analysis. For example, by analyzing data such as page browsing paths, function click frequency, and interaction habits, we can evaluate the use effect of functions, further optimize the interaction process, and improve operational efficiency. Performance monitoring data, such as crash logs and system error information, can help us discover potential problems and improve the stability of application operation. In addition, if you authorize separately, we may also provide you with content recommendations that are more in line with your interests based on historical behavior to improve the relevance of services.

To ensure the security of the platform and prevent malicious behavior, we will use technical means to analyze data such as device identification codes, IP addresses, login behaviors, etc. to identify abnormal operations and prevent risks such as spam account registration, cheating, or content abuse. At the same time, we use encryption, security audits, access control and other measures to protect your data from illegal access, leakage or tampering. In the event of disputes, complaints, reports, etc., we may also retrieve relevant operation records based on needs to assist in investigating and handling disputes.

Subject to compliance with laws and regulations, if judicial authorities or regulatory authorities make information disclosure requests in accordance with the law, we will provide relevant information in accordance with the law. In addition, in emergency situations involving users, platforms or public interests, we may use relevant information for rapid response processing; or when we find possible violations such as infringement of intellectual property rights and threats to personal safety, we will take corresponding measures in accordance with the law to protect legitimate rights and interests.

Lumon respects and protects your privacy. Unless it complies with legal provisions or obtains your explicit consent in advance, we will not disclose or share your personal information with any third party. All partners involved in information processing must comply with strict confidentiality obligations and implement data protection standards no less than this policy.

Under legal requirements, we may disclose information in accordance with the law, such as responding to court rulings, investigation requests from law enforcement agencies, or cooperating with regulatory authorities to fulfill legal obligations. We will conduct a prudent assessment in accordance with legal procedures and notify you in a timely manner if feasible.

In emergency situations, such as to protect the lives of users or the public, prevent fraud, or deal with major emergencies, we may disclose relevant information without your authorization to deal with risks.

If Lumon undergoes a merger, asset transfer, or bankruptcy liquidation, your information may be transferred or disposed of as part of the business assets. We will notify you through platform announcements or emails before the change occurs, and the recipient must still comply with this policy. You can choose to continue using the service, or cancel your account and apply for data deletion within a reasonable period of time.

In the process of using Lumon, you can decide whether to publish content (such as text, pictures, etc.) to others. Such sharing is only carried out after you take the initiative or explicitly authorize it. We recommend that you choose to share content carefully and avoid sensitive personal information.

We will not sell your personal information. If it involves cross-border data transmission, we will evaluate and file it in accordance with the law and take necessary protection measures. If there are major changes in the data sharing part of this policy, we will notify you in a timely manner and obtain re-authorization.

Lumon attaches great importance to the security and integrity of users' personal information. We have established a complete data protection system and are committed to providing all users with a safe and reliable use environment. To prevent user information from being accessed, disclosed, abused, modified or damaged without authorization, we have implemented a multi-level security mechanism for the storage and transmission of data.

All collected user data will be encrypted and stored in data centers with international and regional compliance qualifications. These data centers adopt high security standards such as physical isolation, access authentication, and multiple backups to ensure that data is available for a long time and is not illegally accessed. At the same time, Lumon fully enables transport layer encryption protocols (such as HTTPS and TLS) in the data transmission process to prevent data from being attacked or intercepted by middlemen during transmission.

We have established a strict data access control system internally, and only authorized trained employees can access necessary data within the scope of their duties. All access records will be recorded and audited by the system in real time to prevent abuse. We have also deployed application layer firewalls, intrusion detection systems, and abnormal behavior monitoring mechanisms to identify and respond to potential network attacks, malicious traffic, or unauthorized requests.

To ensure the long-term security of data, Lumon regularly conducts system vulnerability scanning, security reinforcement, and third-party security testing, and continuously reviews and optimizes the platform architecture and code. We also have an emergency response mechanism. Once any form of security incident occurs, we will immediately initiate the response process, assess the scope of impact, fix vulnerabilities, and promptly notify relevant users and regulators (if required).

Users' personal information is only used to provide product functions and services, and will not be provided to any unrelated party or used for any purpose beyond the legal scope without authorization. When it is no longer necessary to save user information, Lumon will delete or anonymize it in a timely manner in accordance with laws and regulations and the principle of data minimization to avoid unnecessary risks.

We also remind users to pay attention to the storage of personal information, avoid submitting sensitive data through unofficial channels, or enable unnecessary device permissions during use to minimize the risk of information leakage. If you have any questions about our data security measures or find potential risks, you can contact us through official channels at any time.

Lumon respects and protects each user's right to know, access, correct, delete and control their personal information. During the use of this application, you always have the right to control the personal information provided, and you can decide whether to continue to authorize or withdraw authorization according to your own needs.
