Last updated: August 29, 2026
Chengbang Technology ("we", "us" or "our") respects your privacy. This Privacy Policy explains what personal data we collect through this website (Chengbang Technology official site), how we use it, and the rights you have. It applies to visitors from all regions, with specific notices for the European Union (GDPR) and California (CCPA/CPRA) below.
1. Information We Collect
Inquiry data (provided by you): when you submit an inquiry form, we collect your name, email address, phone number, company name and the content of your message.
Technical data (collected automatically): IP address, browser type, language, and pages visited — used only for website security and, if you consent, for anonymous traffic analysis.
Cookies: we use strictly necessary session cookies for basic website operation. Analytics cookies are loaded only after you click "Accept" in the cookie banner.
2. How We Use Your Information
We use inquiry data to respond to your questions, prepare quotations, and provide after-sales support. We use technical data to keep the website secure and improve its performance. We do not sell, rent or trade your personal data to any third party.
3. Legal Basis (GDPR)
For EU/EEA visitors: we process inquiry data on the basis of our legitimate interest in responding to business inquiries and entering into contracts (Art. 6(1)(b)(f) GDPR), and analytics data only with your consent (Art. 6(1)(a) GDPR), which you may withdraw at any time via your browser settings.
4. Data Retention
Inquiry records are kept as long as needed for business communication, then deleted. You may request deletion at any time by contacting us.
5. Your Rights
Depending on your location, you may have the right to access, correct, delete, restrict or export your personal data, and to object to its processing. California residents additionally have the right to know what personal information is collected and to request its deletion. We do not sell personal information, so there is no opt-out required. To exercise any right, contact us at pitezhang79@gmail.com.
6. Third-Party Services
Our website is hosted on servers operated by our hosting provider. Pages may contain links to third-party platforms (such as YouTube and WhatsApp). When you click such links, their own privacy policies apply; we encourage you to review them.
7. Children
This website is a business-to-business site and is not directed to children under 16. We do not knowingly collect data from children.
