The limited business-contact data we handle when you request API documentation or a quotation, and the choices you have over it.
Effective date: May 16, 2026
Vialdyne ("Vialdyne", "we", "our", "us") is a peptide API manufacturer based in Shanghai, China. We operate vialdyne.com ("Site") as a procurement contact channel for qualified institutional buyers — 503A and 503B compounding pharmacies and outsourcing facilities, EU and UK prescription compounders, pharmaceutical and biotech R&D teams, and licensed distributors.
This is a business-to-business documentation and sourcing site, not a consumer product. We collect only the limited business-contact information needed to answer a sourcing inquiry, qualify a buyer, prepare a quotation, and ship released material with its paperwork. We do not run advertising or retargeting, set no marketing tracking pixels, and never sell your information.
This Policy is written to meet the EU General Data Protection Regulation (GDPR), the California Consumer Privacy Act as amended (CCPA/CPRA), the China Personal Information Protection Law (PIPL), and comparable laws in markets we serve.
For GDPR purposes, Vialdyne is the data controller of the information you submit through the Site. For PIPL purposes, Vialdyne is the personal-information handler. For CCPA/CPRA purposes, we act as a "business" with respect to that information.
Where a signed commercial agreement assigns different roles for personal data exchanged in the course of an order (for example consignee details on a shipment), that agreement governs to the extent of any conflict.
Information you give us directly through an inquiry, quotation request, or correspondence:
Information collected automatically when you browse:
We do not knowingly collect special-category data (health, biometric, racial, political, religious, or sexual-orientation data) through the Site, and we ask that you not include patient-identifiable information in inquiry free text.
We use the information above to:
We never sell, rent, or trade your personal information, and we do not share it with third parties for their own marketing.
We rely on the following bases:
We disclose information to the service providers below, each bound by a written data-processing agreement requiring confidentiality and security at least equivalent to our own:
We engage no marketing-data brokers, ad-tech retargeting networks, or social-media tracking pixels on this Site.
Because we are based in China and several providers operate in the United States and elsewhere, your information will be transferred across borders.
For EU/EEA personal data sent to a non-adequate country, we rely on the European Commission's Standard Contractual Clauses with appropriate supplementary measures consistent with the Schrems II ruling. For UK personal data we use the UK International Data Transfer Addendum.
For onward transfer of PRC data subjects' personal information, we rely on the PIPL Article 38 standard contract and carry out personal-information-protection impact assessments where required.
For California consumer data, the CCPA/CPRA permits cross-border transfer subject to disclosure, which this section provides. Copies of our transfer agreements are available on request to the contact in Section 12.
We retain information only as long as needed for the purposes in this Policy or as law requires:
Once the applicable period ends, we securely delete or irreversibly anonymise the data.
We apply industry-standard safeguards:
No transmission or storage system is perfectly secure. We recommend you use encrypted email or secure file transfer when sending us sensitive commercial or regulatory documents.
If we become aware of a breach affecting your personal data, we will notify the relevant supervisory authority within 72 hours where required (GDPR Article 33) and notify you without undue delay where the breach is likely to result in a high risk to your rights (GDPR Article 34, PIPL Article 57).
Depending on the law that applies to you, you may have the right to:
Outside our direct reply to an inquiry, we send marketing email — regulatory and sourcing briefings, new-SKU notices — only where you have opted in, and every such message carries a one-click unsubscribe honoured within 5 business days. To exercise any right, email info@vialdyne.com with the subject "Privacy Request", stating the right you wish to exercise; we respond within 30 calendar days and may first ask you to verify your identity.
Cookies: we use a minimal set of cookies and similar technologies. Our Cookies Policy lists each one with its purpose and duration and explains how to manage them.
Minors: the Site is for qualified business buyers and is not directed to anyone under 18. We do not knowingly collect data from minors; tell us if you believe we have, and we will delete it.
Contact: privacy matters — info@vialdyne.com with subject "Privacy"; general sales — info@vialdyne.com; post — Vialdyne, Shanghai, China. EU/EEA users may also contact their local data-protection authority directly.
Updates: we may revise this Policy to reflect legal or operational change. We will update the Effective Date above and, for material changes, post a notice on the Site. Continued use after the Effective Date is acceptance of the updated Policy.
