This Privacy Policy explains how Qingdao Derian Hair Products Co., Ltd., trading as DTR Hair Extensions (“DTR”, “we”, “us”), handles personal data collected through this website. It is written for business visitors, prospects and customers, including individuals in the European Economic Area and the United Kingdom.
1. Controller and contact
The data controller is Qingdao Derian Hair Products Co., Ltd., Qingdao, China. For privacy requests or questions, contact Cindy@derianhair.com.
2. Data we collect
When you submit an inquiry, we may collect your name, business email, telephone or WhatsApp number, company name, country or region, product requirements and message. We may also process limited technical information necessary to operate and secure the website.
3. Why we use your data
We use inquiry data to respond to your request, prepare a quote or product proposal, communicate about the requested business relationship, maintain appropriate business records and protect the website from abuse. We do not use inquiry data for unrelated purposes.
4. Legal bases
Where applicable, we process inquiry data because you asked us to respond or take steps toward a business relationship, because we have a legitimate interest in operating a secure B2B website and managing inquiries, or with your consent when you expressly provide it through the form. You may withdraw consent at any time by emailing us; this does not affect processing before withdrawal.
5. Recipients and international transfers
Access is limited to DTR personnel who need the data to respond to your inquiry. If email delivery is enabled, we use an email delivery service provider to send the inquiry to our sales team. As DTR is based in China, your data may be transferred outside the EEA/UK. Where required, we will use appropriate safeguards for such transfers.
6. Retention
We keep inquiry and related business-contact information only for as long as necessary to respond, manage the potential or active business relationship, meet legal record-keeping requirements or resolve disputes. We periodically review whether retained inquiry data is still needed.
7. Your rights
Depending on applicable law, you may request access to, correction of, deletion of, restriction of or objection to processing of your personal data, and data portability. You may also complain to your local data protection authority. To make a request, email Cindy@derianhair.com.
8. Cookies and third-party content
This website does not currently use an advertising or analytics cookie banner. The Contact page embeds OpenStreetMap to display our office area; when you load that map, OpenStreetMap may process information under its own policies. External links, including WhatsApp and OpenStreetMap, are governed by the privacy notices of those services.
9. Security and updates
We use reasonable technical and organisational measures appropriate to the nature of the information we process. No internet transmission is completely secure. We may update this policy as our website or processing changes; the effective date above indicates the latest revision.
