• your enquiry, message and technical requirements; and

• drawings, documents or other attachments that you choose to upload.

Please do not upload sensitive personal data that is not necessary for your enquiry.

When you visit the website, our server or website systems may record:

• your IP address;

• browser and device type;

• the date and time of access;

• the page address and basic operation logs; and

• information needed for website security and troubleshooting.

The actual information collected depends on the configuration of our hosting, security and website-management systems.

2.3 Cookies and analytics information

Our website uses the strictly necessary cookie lantu_cookie_consent to remember your privacy choices. It is stored for approximately 182 days.

After you consent, the website may use first-party analytics storage, including:

• uniqueVisitorDay;

• accessNumber; and

• page address, page name, device type, language, visit count and time spent on a page.

Analytics is disabled by default. You can reject or withdraw analytics consent at any time through “Cookie Settings” in the website footer. For more information, please see the Cookie Settings panel and the relevant information displayed there.

3. Purposes and Legal Bases

We use personal data for the following purposes:

• to respond to your enquiries and requests for quotations;

• to select suitable products;

• to prepare quotations and technical proposals;

• to review drawings and other attachments;

• to take steps at your request before entering into a contract or to perform a contract;

• to improve our website and customer service;

• to maintain website security and prevent misuse; and

• to comply with legal, accounting and tax obligations.

Enquiry processing is generally based on your request, steps taken before entering into a contract, the performance of a contract, our legitimate interests in responding to business enquiries, or a legal obligation, depending on the circumstances. Optional website analytics is processed only on the basis of your consent.

You may refuse analytics consent without affecting your basic use of the website or your ability to submit an enquiry.

4. Sharing and International Transfers

We may provide personal data, where necessary for the purposes described in this Privacy Policy, to:

• authorised employees;

• website hosting, file-storage and enquiry-management service providers; and

• technical-support, email and communications service providers.

The enquiry and attachment functions of this website are currently operated through a website-management platform provided through global86.cn. The specific service provider may process data as a service provider on our behalf. We will only authorise service providers that are subject to appropriate confidentiality, security and data-protection obligations.

When you voluntarily use WhatsApp, email, social-media or other external services, the relevant information may also be processed by those service providers. Their processing is governed by their own privacy policies.

We are located in China, and some information may be processed outside the European Economic Area. Where GDPR applies and a restricted international transfer takes place, we will use an applicable lawful transfer mechanism and appropriate supplementary safeguards where required, such as an adequacy decision, the EU Standard Contractual Clauses or another legally recognised mechanism.

5. Retention

We retain personal data only for as long as necessary to fulfil the purposes for which it was collected, unless a longer period is required or permitted by law:

• Enquiries and contact details: normally up to 24 months after our last contact;

• Drawings and attachments: normally up to 12 months after the enquiry is closed, unless business or legal requirements require a longer period;

• Necessary security logs: retained according to our hosting and security-management requirements; and

• Cookie consent records: approximately 182 days, or until you reset your privacy choices.

After the applicable period, we will delete, anonymise or securely destroy the relevant information, unless a longer period is required by law, needed to establish or defend legal claims, or necessary for an ongoing business relationship.

6. Your Rights

Subject to applicable law, you may request to:

• access your personal data;

• correct inaccurate or incomplete personal data;

• delete your personal data;

• restrict or object to certain processing;

• receive your personal data in a portable format; and

• withdraw consent where processing is based on consent.

Please send requests to tomjin@changyinmetal.com. We may request information reasonably necessary to verify your identity and protect personal data from unauthorised disclosure. We will respond within the period required by applicable law.

If you believe that we have infringed applicable data-protection law, you may lodge a complaint with the data-protection supervisory authority in the country or region where you live, work or believe that an infringement occurred.

7. Information Security

We take reasonable technical and organisational measures to protect personal data, including HTTPS encryption in transit, access controls, secure administration of our systems and backup protection.

However, no method of transmission or storage over the internet can be guaranteed to be completely secure. If a personal-data security incident occurs and notification is required by applicable law, we will take appropriate remedial and notification measures.

8. Children

This website is primarily intended for business customers and professional users. We do not knowingly collect personal data from children. If you believe that a child has provided personal data to us, please contact us so that we can take appropriate steps to delete it.
