This Privacy Policy explains what information we collect when you visit the Site or contact us, how we use it, and the choices and rights available to you. By using the Site, you agree to the collection and use of information in accordance with this policy.

1. Who We Are

The Site is operated by:

For the purposes of the General Data Protection Regulation (GDPR), Wenzhou Beichen Electric Co., Ltd. is the data controller responsible for the personal information described in this policy.

2. Information We Collect

2.1 Information You Provide to Us

When you submit an inquiry, request a quote, or use one of the engineering tools on the Site, we collect the information you enter into the form. Depending on the form, this may include your name, email address, phone number, company name, country, and the product or project details you describe. If you contact us directly by email or WhatsApp, we collect the information contained in that communication, including your phone number if you message us on WhatsApp.

2.2 Information Collected Automatically

We use Google Analytics to understand how visitors use the Site. Google Analytics automatically collects information such as your IP address, browser type and version, device type, operating system, referring URL, pages visited, time spent on pages, and general geographic location (derived from IP address). This information is collected through cookies and similar tracking technologies, as described in Section 5 below.

We do not currently use payment processing, account registration, or e-commerce checkout systems on the Site, so we do not collect payment card details or account passwords.

3. How We Use Your Information

We use the information described above to:

• Respond to your inquiries and quote requests, and communicate with you about products, specifications, pricing and orders;
• Provide the results of the engineering calculators and selector tools on the Site, based on the values you enter;
• Operate, maintain, and improve the Site, including understanding which pages and tools are most useful to visitors;
• Monitor and analyze usage trends through Google Analytics, in aggregate and non-identifying form wherever possible;
• Detect, prevent, and address technical issues, fraud, or misuse of the Site;
• Comply with applicable legal obligations.

We do not use your information for automated decision-making that produces legal or similarly significant effects concerning you, and we do not sell your personal information to third parties for money.

4. Legal Basis for Processing (EEA/UK Visitors)

If you are located in the European Economic Area or the United Kingdom, we rely on the following legal bases under the GDPR to process your personal information:

• Consent — for non-essential cookies and analytics tracking, where required by applicable law;
• Legitimate interests — for responding to your inquiries, operating and improving the Site, and safeguarding it against misuse, where those interests are not overridden by your data protection rights;
• Performance of a contract or steps prior to entering a contract — where you request a quote or engage us regarding a potential order;
• Legal obligation — where processing is necessary to comply with applicable law.

Where we rely on consent, you may withdraw that consent at any time; this will not affect the lawfulness of processing carried out before you withdrew it.

5. Cookies and Tracking Technologies

The Site uses cookies set by Google Analytics to collect the usage information described in Section 2.2. Cookies are small text files stored on your device that allow a website to recognize your browser across visits and pages. We do not currently use advertising or retargeting cookies.

Most browsers let you refuse or delete cookies through their settings. If you disable cookies, some parts of the Site — including the engineering calculators, which may rely on the browser storing your inputs during a session — may not function as intended.

6. How We Share Your Information

We do not sell your personal information. We may share information in the following limited circumstances:

• Service providers — with Google, as the provider of Google Analytics, which processes usage data on our behalf subject to Google's own privacy and data processing terms;
• Business communications — internally within our sales and engineering teams, so we can respond accurately to your inquiry or quote request;
• Legal requirements — where disclosure is required to comply with a legal obligation, protect our rights, or respond to a valid request from a public authority;
• Business transfers — in connection with a merger, acquisition, financing, or sale of company assets, subject to appropriate confidentiality protections.

7. International Data Transfers

Wenzhou Beichen Electric Co., Ltd. is based in China, and we serve customers in more than 25 countries. If you contact us or use the Site from outside China, your information will be transferred to, stored, and processed in China and in the countries where our service providers (such as Google Analytics) operate. Where required by applicable law, we take steps intended to ensure that such transfers are subject to appropriate safeguards, such as standard contractual clauses or an equivalent mechanism recognized under GDPR. By using the Site or submitting an inquiry, you understand that your information may be transferred to and processed in countries with data protection laws that differ from those of your home country.

8. Data Retention

We retain inquiry and quote-request information for as long as reasonably necessary to respond to your request, maintain our business relationship with you, and comply with our legal, accounting, and tax obligations — typically no longer than needed for these purposes unless a longer period is required or permitted by law. Analytics data collected through Google Analytics is retained according to the retention settings in our Google Analytics account and Google's own data retention policies.

9. Data Security

We use reasonable administrative and technical measures intended to protect the information we collect from unauthorized access, disclosure, alteration, or destruction. However, no method of transmission over the internet or method of electronic storage is completely secure, and we cannot guarantee absolute security.

10. Your Rights Under GDPR (EEA/UK Visitors)
