Where relevant, processing may be based on:
your consent;
steps taken at your request before entering into a contract, such as preparing a quotation;
performance of a contract or purchase order;
compliance with legal obligations;
our legitimate business interests where permitted by law, such as operating and securing our Website, responding to business inquiries, preventing fraud, and improving our services;
other lawful grounds permitted by applicable data protection laws.
Where processing is based on consent, you may withdraw your consent as permitted by applicable law.
6. Cookies and Similar Technologies
The Website may use cookies and similar technologies required for website functionality, security, performance, language preferences, forms, and other website features.
We may also use analytics services, including services such as Google Analytics, to understand traffic and website performance.
Depending on their configuration, analytics and similar technologies may collect information such as IP address, device information, browser information, visited pages, referral information, and interaction data.
Where applicable law requires consent before non-essential cookies or analytics technologies are activated, we will seek the required consent.
You may also be able to manage cookies through your browser settings.
Disabling certain cookies may affect Website functionality.
7. How We Share Information
We do not disclose personal information except where reasonably necessary for legitimate business purposes or where required by law.
Information may be shared with the following categories of recipients.
Service Providers
We may use service providers that assist us with:
website hosting;
content delivery and website security;
website maintenance;
form processing;
email delivery;
analytics;
data storage;
IT services;
communications;
logistics or shipping;
professional services.
These providers may process information only to the extent necessary to provide their services, subject to applicable contractual and legal requirements.
Employees and Authorized Personnel
Information may be accessed by employees and personnel who reasonably need it for sales, quotation, engineering, manufacturing, quality, customer service, IT, management, or legal purposes.
Business Partners and Suppliers
Where necessary to respond to or fulfill a specific project, information may be shared with authorized suppliers, subcontractors, logistics providers, or other business partners.
We seek to limit such disclosure to information reasonably necessary for the relevant purpose.
Legal Requirements
We may disclose information where reasonably necessary to:
comply with applicable law;
respond to a court order or lawful government request;
protect our legal rights;
investigate fraud or security incidents;
enforce agreements;
protect the safety or property of Golden Collar, our customers, or others.
Corporate Transactions
If all or part of our business is involved in a merger, acquisition, restructuring, financing, asset sale, or similar transaction, relevant information may be transferred as part of that transaction subject to applicable law.
8. Sale or Sharing of Personal Information
Golden Collar is a manufacturer and B2B supplier and does not operate as a data broker.
We do not sell personal information for monetary consideration as part of our ordinary business.
Certain analytics, advertising, or similar technologies, if enabled on the Website, may involve disclosures that are treated as “sharing,” “targeted advertising,” or similar activities under certain privacy laws.
Where applicable law gives you the right to opt out of such processing, we will provide or honor the legally required method for exercising that right.
9. International Data Transfers
Golden Collar is based in China and serves customers and website visitors in multiple countries.
As a result, information you provide may be transferred to, stored in, or processed in China or in other countries in which our service providers operate.
Data protection laws in these countries may differ from those in your country.
Where applicable law requires specific safeguards, contractual protections, consent, assessments, or other mechanisms for international transfers, we will implement the measures required by applicable law.
10. Data Retention
We retain personal information only for as long as reasonably necessary for the purposes for which it was collected, including responding to inquiries, preparing quotations, maintaining business records, supporting customer relationships, complying with legal requirements, resolving disputes, and enforcing agreements.
Retention periods may depend on factors such as:
whether an inquiry resulted in a quotation or order;
whether an ongoing customer or supplier relationship exists;
whether technical drawings remain relevant to repeat production;
applicable accounting, tax, contractual, product-quality, or legal retention requirements;
the need to establish, exercise, or defend legal claims.
When information is no longer reasonably required, we may delete, anonymize, or securely archive it as appropriate and as permitted by law.
11. Protection of Drawings and Technical Files
We recognize that drawings, CAD files, specifications, and similar documents submitted for quotation may contain commercially important information.
We use reasonable administrative, technical, and organizational safeguards intended to protect such files against unauthorized access, disclosure, alteration, or loss.
Access should be limited to personnel and service providers who reasonably require the information for quotation, technical evaluation, production, quality, support, or related business purposes.
Submitting a drawing through the Website does not by itself create a separate non-disclosure agreement.
If a project requires contractual confidentiality obligations beyond the protections described in this Privacy Policy, please contact us before submitting sensitive or proprietary files so that an appropriate NDA or other agreement can be considered.
12. Information Security
We use reasonable technical and organizational safeguards designed to protect personal and business information against:
unauthorized access;
loss;
misuse;
alteration;
disclosure;
destruction.
However, no internet transmission, website, email system, or storage system can be guaranteed to be completely secure.
You should therefore avoid submitting information that is unnecessary for your inquiry.
Unless specifically requested through an appropriate secure process, please do not submit sensitive personal information such as government identification numbers, payment card information, medical information, passwords, or other highly sensitive information through our quotation or contact forms.
13. Marketing and Newsletter Communications
If you voluntarily subscribe to our newsletter or marketing communications, we may send you information about products, materials, manufacturing capabilities, technical content, company updates, exhibitions, or related topics.
You may unsubscribe at any time using the unsubscribe method provided in the communication or by contacting us.
Unsubscribing from marketing does not prevent us from sending necessary business communications relating to an inquiry, quotation, order, or existing customer relationship.
14. Your Privacy Rights
Depending on your location and applicable law, you may have rights regarding your personal information, which may include the right to:
request information about how your personal information is processed;

These rights are not absolute and may be subject to legal exceptions.

We may need to verify your identity before fulfilling certain requests.
We will not discriminate against you for exercising a privacy right protected by applicable law.
15. California and Other U.S. State Privacy Rights

We do not intentionally collect sensitive personal information through the Website for purposes unrelated to providing our products, responding to inquiries, or conducting legitimate business operations.
16. European Economic Area, United Kingdom, and Similar Jurisdictions
Where the GDPR, UK GDPR, or similar legislation applies, you may have additional rights including access, correction, erasure, restriction, objection, and portability.
You may also have the right to lodge a complaint with the competent supervisory authority in your country.
