1. Who We Are
This website, huanhuanpower.com, is operated by Dongguan Huanhuan Energy Technology Co., Ltd. (“HHPOWER”, “we”, “us”), a battery manufacturer located at Building D, No. 5, Jincheng Road 2nd Lane, Fenggang Town, Dongguan City, Guangdong Province, China.
For any question about this policy or about your personal data, contact us at mayliu@huanhuanpower.com or +86 137 5106 8785.
2. What We Collect
Information you give us. When you submit an inquiry form, request a quotation, place an order or contact us, we collect the details you enter — typically your name, company name, business email, phone or WhatsApp number, country, product of interest and the content of your message.
Order information. If you place an order, we collect billing and shipping details, purchase history, payment status and correspondence about the order. We do not receive or store your full card details; card payments are processed by our payment provider.
Information collected automatically. Like most websites, our server records technical data when you visit: IP address, browser type, device type, referring page, pages viewed and the date and time of your visit. We use this to keep the site secure and to understand which pages are useful.
Cookies. We use cookies that are necessary for the site to work — for example keeping items in your cart or remembering that you dismissed a notice. We may also use analytics cookies to measure traffic. You can block or delete cookies in your browser settings; essential functions such as the cart may then stop working.
3. Why We Use It
- To answer your inquiry and prepare a quotation.
- To process, produce, ship and support your order.
- To provide warranty service and handle claims.
- To send transactional messages — order confirmations, shipping notices, invoices.
- To send product or industry updates, only where you have asked for them; you can unsubscribe at any time.
- To keep the website secure, prevent spam and abuse, and diagnose technical problems.
- To meet accounting, tax and export compliance obligations.
Where data protection law requires a legal basis, we rely on: performance of a contract (orders), our legitimate interest in running and improving our business (inquiries, site security), your consent (marketing emails, non-essential cookies), and legal obligation (tax and export records).
4. Who We Share It With
We do not sell your personal data. We share it only where necessary, with:
- Shipping carriers and freight forwarders — to deliver your order, including the consignee name, address, phone number and the dangerous goods documentation required for lithium batteries.
- Payment providers — to process payments and manage fraud risk.
- Email and hosting providers — who deliver our messages and host this website.
- Newsletter and analytics providers — where you subscribe or where analytics is enabled.
- Professional advisers and authorities — where required by law, court order, or to establish or defend a legal claim.
5. International Transfers
We operate from China and our service providers may process data in other countries. Where personal data is transferred internationally, we take reasonable steps to ensure it remains protected, including contractual safeguards with the providers we use.
6. How Long We Keep It
| Inquiry and quotation records | Up to 24 months from last contact |
| Order, invoice and shipping records | Up to 7 years, as required for tax and accounting |
| Warranty and claim records | Warranty period plus 12 months |
| Marketing subscriptions | Until you unsubscribe, then removed from the active list |

To exercise any of these rights, email mayliu@huanhuanpower.com. We respond within 30 days. We may ask for proof of identity to protect your data.
8. Security
We use HTTPS across the site, restrict administrative access, and keep software updated. No method of transmission or storage is completely secure, but we take reasonable technical and organisational measures appropriate to the sensitivity of the data.
9. Children
This site sells industrial products to businesses. It is not directed at children, and we do not knowingly collect data from anyone under 18.
