Please read this Privacy Policy carefully before using the Website or providing us with personal information. If you do not agree with this Policy, please do not submit personal information to us.

We will not make automated decisions that have a significant impact on your rights and interests solely on the basis of this information.

2.3 Information Obtained Through Business Relationships or Public Sources

Where reasonably necessary for business communications, we may obtain your professional contact information from your employer, mutual business contacts, industry exhibitions, publicly available corporate websites, or other lawfully available public sources.

We will use such information in accordance with applicable laws, taking into account its source, nature, and the purpose for which it is processed.

4. Cookies and Similar Technologies

The Website may use essential cookies or similar technologies to maintain language preferences, security protection, form status, access preferences, and basic statistical functions.

Essential cookies are necessary for the proper operation of the Website. Disabling them may prevent certain Website functions from working correctly.

For non-essential analytics, advertising, or other tracking technologies, we will provide appropriate information and choices as required by applicable laws. Where required, we will obtain your consent before enabling such technologies.

You may delete or restrict cookies through your browser settings, although doing so may affect certain Website functions.

If the Website does not currently use non-essential cookies, this section does not mean that we have enabled advertising tracking or user-profiling functions.

5. Entrusted Processing, Sharing, Transfer, and Public Disclosure

To operate the Website and process business inquiries, we may engage service providers to process necessary information on our behalf. These service providers may provide:

Website hosting;
Content delivery;
Cybersecurity services;
Database services;
Email services;
File storage;
Website maintenance; and
Website analytics.

Depending on the Website’s actual technical configuration, such service providers may include infrastructure providers such as Cloudflare.

We will require entrusted service providers to process information only according to our instructions, for the agreed purposes, and within the necessary scope. We will also require them to implement appropriate confidentiality and security measures.

The specific service providers involved will be determined by the Website’s actual configuration at the time it becomes operational.

5.2 Provision or Sharing of Personal Information

We will require the recipient to continue to comply with this Policy and the obligations imposed by applicable laws. If the recipient changes the original purposes or methods of processing, it must obtain your consent again as required by law.

5.4 Public Disclosure

As a general principle, we will not publicly disclose your personal information.

If public disclosure becomes necessary, we will fulfil the applicable notification obligations and obtain your separate consent as required by law, unless otherwise provided by applicable laws and regulations.

6. Cross-Border Processing of Personal Information

The Website may serve customers in China and other countries or regions. Some servers used for website hosting, cybersecurity, email, or other technical services may be located outside the People’s Republic of China.

If personal information is provided to a recipient outside the People’s Republic of China during the actual operation of the Website, we will take appropriate measures in accordance with applicable laws, including:

Informing you of the overseas recipient’s name, contact details, processing purposes, processing methods, the types of personal information involved, and the methods and procedures through which you may exercise your rights against the overseas recipient;
Obtaining your separate consent where required by law;
Completing any required personal information protection certification, standard contract filing, security assessment, or other statutory procedure; and
Requiring the overseas recipient to process your personal information in accordance with the protection standards prescribed by applicable laws.

If the Website does not provide personal information to overseas recipients after it becomes operational, we will revise this section to reflect the actual circumstances.

7. Retention Period

We retain personal information only for the shortest period necessary to achieve the purposes described in this Policy, unless a longer retention period is required by applicable laws, contractual obligations, dispute-resolution requirements, quality-traceability requirements, or audit requirements.

In general:

Ordinary inquiry information that does not lead to a business relationship will be retained until the period reasonably necessary to complete communications, conduct appropriate follow-up, and resolve potential disputes has expired;
Information associated with quotations, samples, orders, or contracts will be retained in accordance with contractual performance, finance, taxation, quality traceability, and records-management requirements;
Website security and operational logs will be retained for the period necessary to conduct security audits, troubleshoot faults, and prevent misuse; and
If you withdraw your consent or request deletion, we will process your request to the extent permitted by applicable laws. This does not apply to information that must be retained by law or to backup copies that cannot technically be deleted immediately. Such backup copies will remain isolated from ordinary use and will be deleted or anonymized when the applicable backup cycle expires.

When the applicable retention period expires, we will delete or anonymize the relevant personal information.

8. Information Security

We implement administrative, technical, and physical security measures appropriate to the nature of our business, the categories of information involved, and the level of risk.

These measures may include:

Access controls;
Permission management;
Transmission protection;
Logging and monitoring;
Backup and recovery procedures;
Service-provider management; and
Confidentiality requirements for personnel.

These measures are intended to protect personal information against unauthorized access, disclosure, alteration, loss, misuse, or other unlawful processing.

No method of transmission or storage over the internet can be guaranteed to be completely secure. If a personal information breach, alteration, or loss occurs or is likely to occur, we will take remedial measures and notify the relevant authorities and affected individuals as required by law.

Before sending us drawings, BOMs, or other materials that may contain trade secrets, we recommend that you contact us to confirm an appropriate transmission method and confidentiality arrangement. Ordinary email may not be suitable for transmitting highly confidential materials in all circumstances.

To protect information security, we may ask you to provide information reasonably necessary to verify your identity. Once your identity and request have been verified, we will respond within the period and in the manner prescribed by applicable laws.

Withdrawal of consent will not affect the lawfulness of processing carried out on the basis of your consent before the withdrawal.

If your request is manifestly unreasonable, repeatedly submitted, or would seriously harm the lawful rights and interests of another person, we may refuse the request or charge a reasonable fee to the extent permitted by law. If we refuse your request, we will explain the reasons for doing so.
