Privacy Policy

1. Who we are

The data controller for personal information submitted through this website is Chengguang Power Tech Co., Ltd. (晋州成光电源有限公司), Maju Industrial Park, Jinzhou, Hebei, China. The Dingwei Battery website is the export-facing brand operated on behalf of this manufacturer. This policy describes how we handle the information you provide here.

2. Information we collect

We collect only the information you choose to give us, typically through the RFQ form or direct contact (email, WhatsApp or phone). This may include:

• Business identity — company name, country or market, and buyer type (distributor, retailer, fleet operator, brand owner, or other).
• Battery requirements — battery type (SLI / AGM / EFB / Heavy Duty), standard (JIS / DIN / BCI / AS / SA / EN), model or case reference, voltage, capacity (Ah), CCA reference, annual volume and packaging preference.
• Contact details — your email address and phone / WhatsApp number, where you provide them.
• Free-form notes — any additional requirements you include in the notes field or in your messages.

We do not collect sensitive personal data, and we do not require an account or login to use this website.

3. How we use your information

We use your information solely to respond to your inquiry and to support a potential or actual OEM / private-label program. Specifically:

• To prepare a battery quotation and assess specification, volume and market fit.
• To communicate with you about the requested program, sampling, production and shipment.
• To maintain legitimate business records of inquiries and transactions.

We do not sell, rent or trade your contact details, and we do not use them for third-party marketing.

4. Legal basis for processing (EEA / UK)

Where the EU General Data Protection Regulation (GDPR) or UK GDPR applies, we rely on the following legal bases:

• Steps prior to entering a contract (Art. 6(1)(b)) — processing your inquiry to prepare a quotation.
• Legitimate interests (Art. 6(1)(f)) — maintaining business records and protecting our systems.
• Consent (Art. 6(1)(a)) — where you explicitly opt in to receive follow-up communication.

5. How we share information

We share your information only as necessary to fulfil your inquiry, and never for third-party advertising. This may include:

• Logistics and freight providers — to arrange export, shipment and delivery where an order results.
• Payment and banking intermediaries — to process documentary payments (T/T or L/C).
• Professional advisers or authorities — where required by applicable law or regulation.

6. Cookies and local storage

This website does not use advertising or behavioural-tracking cookies. We may use basic, privacy-respecting analytics (aggregate traffic data) to understand which pages are visited; this does not identify you personally. No personal data is stored in cookies for the purpose of targeting or profiling.

7. International data transfers

We are based in China, and the information you submit may be processed in China as well as in the country where you are located, in order to respond to you. Where your information is transferred across borders, we take reasonable steps to apply appropriate safeguards and to limit access to those who need it.

8. Data retention

Inquiry details are retained only as long as needed to service the request and to keep legitimate business records, after which they are deleted or anonymised. If an inquiry does not lead to an order, we retain the record for a limited period to handle any follow-up, then remove it.

9. Data security

We apply reasonable technical and organisational measures to protect your information against unauthorised access, alteration, disclosure or destruction. No method of transmission or storage is completely secure, and we cannot guarantee absolute security, but we work to keep your data protected in line with industry practice.

10. Your rights

Depending on your location, you may have the right to:

• Access a copy of the personal data we hold about you.
• Request correction of inaccurate data.
• Request deletion of your data (“right to be forgotten”).
• Restrict or object to certain processing.
• Request data portability where it applies.

Where the California Consumer Privacy Act (CCPA/CPRA) applies, California residents have corresponding rights of access, deletion and opt-out of the sale of personal information — noting that we do not sell personal information. To exercise any of these rights, contact us at the details below. We will respond within the time required by applicable law.

11. Children’s privacy

This website is a business-to-business resource and is not directed at children under 16. We do not knowingly collect personal information from children.

12. Changes to this policy

We may update this policy from time to time. The “Last updated” date at the top of this page shows the most recent revision. Continued use of the website after a change indicates acceptance of the updated policy.
