1. Scope and Data Controller
This Privacy Policy explains how Hangzhou A-Gen Biotechnology Co., Ltd. ("A-Gen", "we", "us" or "our") collects and processes personal data in connection with the English-language A-Gen website at https://en.a-gen.com/ (the "Website"). It applies to business visitors and representatives who browse the Website or submit a business inquiry, request a product document or Certificate of Analysis (COA), request a sample, or make a distributor, agency or OEM/ODM inquiry.
This Policy applies only to the Website. It does not apply to third-party websites, social-media services or other services that may be linked from the Website; those services are governed by their own privacy notices.
2. Personal Data We Collect
Information you provide. When you use a Website form or otherwise contact us, we may collect your name, business telephone number, business email address, company name, inquiry type, product of interest, and the message or other information you choose to provide. For sample requests, we may also collect the requested sample name or item number, recipient details, and delivery address. Please provide only information that is relevant to your business request.
Information collected automatically. When you visit the Website, our servers and analytics tools may collect technical and usage information, such as IP address, browser and device information, operating system, referring URL, pages viewed, interactions with the Website, and the date and time of access. This information may be collected through server logs, cookies and similar technologies.
We do not ask you to provide sensitive personal data through the Website. Please do not include unnecessary sensitive information, such as government identification numbers, financial-account details, health information or other special-category data, in a contact form or message.
3. Cookies and Analytics
The Website uses a language-preference cookie to remember the selected site language. It also uses Google Analytics, Baidu Analytics and Google Tag Manager-related technologies to understand how visitors use the Website and to improve its performance and content. These technologies may collect online identifiers, device and browser information, IP address and Website-usage information.
You can manage or delete cookies through your browser settings. Blocking cookies may affect certain Website functions. Google and Baidu process information in accordance with their own privacy policies; we do not control their independent processing of data.
4. How We Use Personal Data
We use personal data to respond to your inquiry; provide product, technical, sales, COA, sample-request or distributor/OEM/ODM information; communicate with you about your request; operate, secure and improve the Website; analyse Website performance and usage trends; prevent misuse or fraud; and comply with applicable legal obligations.
Where applicable law requires a legal basis for processing, we rely on your consent (for example, where you submit a request or consent to cookies), our legitimate interests in operating and improving a business-to-business website and responding to commercial inquiries, steps taken at your request before entering into a business relationship, and compliance with legal obligations. We will use your contact details for marketing only where permitted by applicable law.
5. How We Share Personal Data
We may share personal data with service providers that support our Website, hosting, IT, analytics, communications and professional-advisory functions; with our affiliated companies, regional sales contacts or authorized distributors where necessary to respond to your business request; and with authorities or other parties where disclosure is required by law or necessary to protect legal rights, security or property.
We may also disclose information in connection with a corporate transaction, such as a merger, acquisition, financing, reorganization or sale of assets, subject to applicable law. We do not sell personal data for monetary consideration.
6. International Data Transfers
A-Gen is based in China and serves business visitors in multiple markets. Personal data may be accessed or processed in China and in other countries where we, our service providers, analytics providers or business partners operate. Data-protection laws in those countries may differ from the laws of your country. Where required by applicable law, we will take appropriate steps to protect personal data transferred across borders.
7. Retention and Security
We retain personal data only for as long as reasonably necessary for the purposes described in this Policy, including managing your inquiry or business relationship, maintaining appropriate business records, resolving disputes, enforcing agreements and meeting legal obligations. We may retain de-identified or aggregated information for longer periods.
We use reasonable technical and organizational measures designed to protect personal data against unauthorized access, loss, misuse, alteration or disclosure. However, no Internet transmission or storage system can be guaranteed to be completely secure.
8. Your Rights and Choices
Depending on where you live and subject to applicable law, you may have rights to request access to, correction of, deletion of or restriction of processing of your personal data; to object to certain processing; to request data portability; or to withdraw consent. Withdrawing consent will not affect the lawfulness of processing carried out before the withdrawal.
