3.4.6 Personal information disclosed by you to the public on your own;
3.4.7 Collected from legally publicly disclosed information, such as legal news reports, government information disclosure, and other channels.
According to legal provisions, sharing or transferring de-identified personal information, and ensuring that the data recipient cannot restore and re-identify the personal information subject, does not constitute external sharing, transfer, or public disclosure of personal information. The storage and processing of such data will not require separate notification to you or your consent.

4. How We Store and Protect Your Personal Information Security

4.1 Except as otherwise stipulated by laws, regulations, or regulatory authorities, we only store your personal information for the period necessary for the purposes described in this Policy and for the shortest time limit. Our criteria for determining the aforementioned period include:
4.1.1 Completing the transaction purposes related to you, maintaining corresponding transaction and business records, and responding to your possible queries or complaints;
4.1.2 Ensuring the security and quality of the services provided by the platform to you;
4.1.3 Whether you agree to a longer retention period;
4.1.4 Whether there are other special agreements on the retention period.
4.1.5 The period stipulated by laws, regulations, or regulatory authorities.
After your personal information exceeds the retention period, weldZip will delete your personal information or anonymize it in accordance with the requirements of applicable laws (if you are a minor, after your personal information exceeds the retention period, weldZip will process your personal information in accordance with relevant laws and regulations). If deletion cannot be performed in accordance with relevant requirements due to special circumstances, the platform will explain this part of the matter to you.
If we terminate services or operations, we will promptly stop continuing to collect your personal information, simultaneously notify you in advance in accordance with relevant legal and regulatory requirements, and after the period necessary for the purposes stated in this Policy, the expiration of the time limit required by laws, regulations, and regulatory requirements, or after the termination of services or operations, delete or anonymize your personal information, unless otherwise stipulated by laws, regulations, or regulatory authorities.

4.2 Personal information collected and generated during our operations within the territory of the People's Republic of China is stored within China. The following exceptions apply:
4.2.1 Clearly stipulated by laws and regulations;
4.2.2 Obtaining your authorization and consent;
4.2.3 Your use of products and services involves cross-border, and we need to provide your personal information overseas.
For the above situations, we will ensure that sufficient protection is provided for your personal information in accordance with this Policy and national laws and regulations.

4.3 We attach great importance to personal information security, have established a dedicated security team, and take all reasonably feasible measures to protect your personal information:
4.3.1 Data Security Technical Measures
We will adopt security protection measures that comply with industry standards, including establishing reasonable system specifications and security technologies to prevent your personal information from unauthorized access, use, modification, and to avoid damage or loss of data. Network services adopt various encryption technologies. For example, in some services, we will use encryption technology (such as SSL) to protect your personal information, use encryption technology to encrypt and save your personal information, and use isolation technology for isolation. When using personal information, such as personal information display and personal information association calculation, we use various data desensitization technologies to enhance the security of personal information during use. We use strict data access permission controls and multi-factor identity authentication technology to protect personal information and avoid data being used improperly.
4.3.2 Other Security Measures We Take to Protect Personal Information
4.3.2.1 We manage and regulate the storage and use of personal information by establishing data classification and grading systems, data security management specifications, and data security development specifications.
4.3.2.2 We conduct comprehensive security control over data through personal information contact confidentiality agreements, monitoring, and audit mechanisms.
4.3.2.3 We also hold security and privacy protection training courses to strengthen employees' awareness of the importance of protecting personal information and security awareness.
4.3.2.4 We only allow our and our affiliates' employees and partners who need to know this personal information to access your personal information, and we have set strict access permission controls and monitoring mechanisms for this purpose. We also require all personnel who may come into contact with your personal information to fulfill corresponding confidentiality obligations. Failure to fulfill these obligations may result in legal liability or termination of the cooperative relationship with us.
4.3.3 The Internet is not an absolutely secure environment, and communication methods such as email, instant messaging, social software, or other service software cannot be determined to be completely encrypted. We recommend that you use complex passwords when using such tools and pay attention to protecting your personal information security.
4.3.4 We will endeavor to ensure or guarantee the security of any personal information you send to us. If our physical, technical, or management protection facilities are compromised, resulting in unauthorized access, public disclosure, alteration, or destruction of personal information, causing damage to your legitimate rights and interests, we will bear corresponding legal liability.

4.4 Security Incident Handling
In the unfortunate event of a personal information security incident, we will promptly inform you in accordance with the requirements of laws and regulations: the basic situation of the security incident and its possible impact, the measures we have taken or will take, suggestions for you to independently prevent and reduce risks, and remedial measures for you, etc. We will simultaneously inform you of the relevant situation of the incident by email, letter, SMS, phone, push notification, etc. If it is difficult to inform each personal information subject, we will adopt reasonable and effective methods to issue an announcement. At the same time, we will also proactively report the handling of personal information security incidents to the regulatory authorities as required.
Please understand that due to technical limitations and the limitations of risk prevention, even though we have tried our best to strengthen security measures, we cannot always guarantee 100% security of personal information. You need to understand that the systems and communication networks you use to access weldZip services may have problems due to circumstances beyond our control.
