1. Introduction

Ruiyu Material Co., Limited (referred to throughout this document as the Company, we, us, or our) provides computer systems design and related services, including systems architecture, software and data engineering, security, and managed operations. This Privacy Policy explains how we collect, use, share, and protect personal information when you visit our website at https://www.npaops.mom, contact us, or otherwise engage with our services.

Our website and digital materials are developed and maintained with the involvement of Ruiyu Metals, our development partner. Ruiyu Metals assists the Company in building and operating the technology that powers this site, and any personal information processed in that context is handled in accordance with the commitments set out in this policy.

We respect the privacy of every visitor and every client. This policy is intended to be clear and complete, so that you can understand exactly what information we handle, why we handle it, and what choices you have. Please read it carefully. By using our website or services, you acknowledge the practices described here.

2. Scope of This Policy

This policy applies to personal information that we collect through our website, through email and telephone communications with us, and through the provision of our professional services. Personal information means any information that relates to an identified or identifiable individual.

This policy does not apply to information that is publicly available, information that has been anonymized or aggregated in a way that cannot reasonably be linked back to an individual, or information that we process solely on behalf of a client under a separate data processing agreement.

When we act as a service provider to a business client, the primary responsibility for the personal information within that client environment rests with the client. In such cases, our handling of that information is governed by our written agreement with the client rather than this policy, and you should direct any questions to that client in the first instance.

3. Who We Are

The Company is Ruiyu Material Co., Limited, a company organized and operating with its registered office at Rm D07 8/F Kai Tak Factory Building, 99 King Fuk Street, Kowloon City, Hong Kong (HK). We operate in the computer systems design and related services industry, which falls within the professional, scientific, and technical services sector.

For the purposes of applicable data protection law, the Company is the controller of the personal information described in this policy. This means we determine the purposes and means by which that information is processed.

Our website is located at https://www.npaops.mom. Our primary contact email address is service@npaops.mom, and our telephone number is +17197193436. You can reach us through either channel if you have any question about this policy or about how we handle personal information.

4. Information We Collect

We collect several categories of information, each for a specific and necessary purpose. We collect only what we reasonably need to operate our website, respond to inquiries, and deliver our services.

Information you provide directly

When you contact us through our website form, send us an email, or speak with us by telephone, we may collect your name, email address, telephone number, organization name, and the content of your message. When you subscribe to our newsletter, we collect your email address. When you engage us for services, we may collect billing and contact details needed to manage that relationship.

Information collected automatically

When you visit our website, our systems automatically collect certain technical information, including your internet protocol address, browser type, operating system, referring page, pages viewed, and the date and time of your visit. This information is used to keep the site secure and to understand how visitors move through it.

Information from third parties

In limited circumstances we may receive information about you from third parties, such as a referral from a business partner or a directory listing. We treat such information with the same care as information you provide directly.

5. How We Collect Information

We collect information through several transparent channels. Understanding these channels helps you decide how much you wish to share with us.

Direct collection occurs when you submit a form on our website, send us an email, call us, or enter into a service agreement with us. In each case the collection is initiated by you, and you are in control of the information you provide.

Automatic collection occurs through cookies and similar technologies as your browser interacts with our site. This collection is limited to technical and usage data and does not identify you by name unless you also choose to identify yourself through a form or message.

We do not purchase personal information from data brokers, and we do not engage in hidden tracking or surveillance of visitors beyond the standard analytics described in this policy.

6. How We Use Information

We use personal information for purposes that are directly related to operating our business and serving you. The primary uses are described below.

To respond to inquiries

When you contact us, we use your name and contact details to understand your request and to reply. Without this information we would have no way to reach you with an answer.

To deliver services

When you become a client, we use your contact and billing information to perform our obligations under the service agreement, to communicate about the work, and to issue and receive invoices.

To improve our website and services

We use aggregated usage data to understand which parts of our website are helpful and which need improvement. This analysis is performed on aggregate data and is not used to profile individual visitors.

To meet legal obligations

We may process information as necessary to comply with applicable law, to respond to lawful requests from authorities, and to protect our rights and the rights of others.

To communicate with you

If you subscribe to our newsletter or consent to marketing communications, we use your email address to send the updates you requested. You may withdraw this consent at any time.

7. Legal Bases for Processing

Where data protection law requires a legal basis for processing, we rely on one or more of the following grounds.

Consent is the basis we rely on when you choose to receive marketing communications or when you voluntarily submit information through our website. You may withdraw consent at any time without affecting the lawfulness of processing carried out before the withdrawal.

Contract is the basis we rely on when processing is necessary to enter into or perform a service agreement with you or your organization.

Legitimate interests cover processing that is necessary for our business and that does not override your rights, such as maintaining the security of our website, preventing fraud, and responding to inquiries you have initiated.

Legal obligation covers processing required to comply with applicable laws and regulations, including record keeping and responses to lawful requests.

8. Cookies and Tracking Technologies

Cookies are small text files placed on your device when you visit a website. We use a limited set of cookies and similar technologies to make our website function correctly and to understand general usage patterns.

Essential cookies are necessary for the site to operate, such as remembering basic preferences. These do not require consent. Analytical cookies help us understand how visitors use the site, for example which pages are most frequently viewed. We use these only in an aggregated and anonymized manner where possible.

You can control cookies through your browser settings. Most browsers allow you to refuse cookies or to delete those already stored. Please be aware that disabling certain cookies may affect how parts of our website function.

9. Analytics and Usage Data

To understand how our website is used, we may employ standard analytics tools that collect information such as pages visited, time spent on the site, and the general region from which a visitor connects. We configure these tools to minimize the amount of identifying information collected and to respect the choices you make in your browser.

The analytics data we review is aggregated. We do not use it to build individual profiles, to target advertising, or to make automated decisions that affect you. Its sole purpose is to help us maintain a website that is useful, fast, and easy to navigate.

If you prefer not to be included in analytics, you may adjust your browser privacy settings or use any opt out mechanism offered by the analytics provider, and our site will continue to function normally.

10. How We Share Information

We do not sell personal information to anyone, and we do not rent or trade contact lists. We share personal information only in the limited circumstances described below.

We may share information with service providers who perform functions on our behalf, such as hosting our website, delivering email, or processing payments. These providers are bound by contract to use the information only for the services they provide to us and to protect it to a standard consistent with this policy.

We may share information with professional advisers such as legal counsel and accountants where necessary to protect our rights or comply with obligations. We may also disclose information when required by law, by a court order, or by a lawful request from a government or regulatory authority.

In the event of a merger, acquisition, or sale of all or part of our business, information may be transferred as part of that transaction. We will notify affected individuals as required by applicable law.

11. Data Retention

We retain personal information only for as long as necessary to fulfill the purposes described in this policy, unless a longer retention period is required or permitted by law.

Inquiries and correspondence are retained for a reasonable period to allow us to respond and to maintain a record of our communications. Service records are retained for the duration of the client relationship and for any additional period required by applicable accounting, tax, or legal obligations.

When information is no longer needed, we delete it or irreversibly anonymize it. We review our retention practices periodically to ensure that information is not kept longer than necessary.

12. Data Security

We apply appropriate technical and organizational measures to protect personal information against unauthorized access, alteration, disclosure, or destruction. These measures include access controls, encryption in transit, and regular review of our systems.

Access to personal information is limited to those team members and service providers who need it to perform their duties, and all access is subject to confidentiality obligations.

While we take reasonable precautions, no method of transmission or storage is completely secure. We cannot guarantee absolute security, and we encourage you to use strong passwords and to be cautious when sharing personal information online.

13. International Data Transfers

The Company is based in Hong Kong, and our operations, systems, and service providers may be located in other jurisdictions. As a result, personal information may be transferred to and processed in countries whose data protection laws differ from those in your country of residence.

When we transfer personal information across borders, we take steps to ensure that it receives an adequate level of protection, such as entering into standard contractual clauses or relying on other safeguards recognized by applicable law.

If you would like more detail about the safeguards we use for international transfers, please contact us using the information in the Contact Information section of this policy.

14. Your Privacy Rights

Depending on your jurisdiction, you may have certain rights regarding your personal information. We honor these rights where they apply, and we aim to respond to requests promptly.

You may have the right to request access to the personal information we hold about you, to request correction of inaccurate information, to request deletion of your information, to object to or restrict certain processing, and to request a copy of your information in a portable format.

Where we rely on consent, you have the right to withdraw that consent at any time. You also have the right to lodge a complaint with a data protection authority in your jurisdiction if you believe your rights have been violated.

To exercise any of these rights, contact us at service@npaops.mom. We may ask you to verify your identity before fulfilling a request, and we will respond within the timeframes required by applicable law.

15. Privacy for Children

Our website and services are directed at businesses and professional users. We do not knowingly collect personal information from children, and we do not direct our marketing or content toward children.

If you are a parent or guardian and believe that a child in your care has provided personal information to us, please contact us at service@npaops.mom. We will take steps to delete such information from our systems as quickly as possible.

If we become aware that we have inadvertently collected personal information from a child without appropriate consent, we will delete that information promptly.

16. Third-Party Links and Services

Our website may contain links to third-party websites or services that we do not own or control. This privacy policy does not apply to those websites, and we are not responsible for their privacy practices.

We encourage you to review the privacy policies of any third-party website you visit before providing personal information. The presence of a link on our site does not imply that we endorse the linked site or its practices.

17. Do Not Track Signals

Some browsers offer a Do Not Track setting that sends a signal to websites requesting that they not track your activity. At this time there is no single industry standard for how websites should respond to such signals.

We do not engage in cross-site behavioral tracking of our visitors. To the extent that we use analytics, we do so for the limited purposes described in this policy, and we respect any browser-level opt out settings you enable.

18. Changes to This Policy

We may update this privacy policy from time to time to reflect changes in our practices, our technology, or applicable law. When we make changes, we will revise the last updated date at the top of this page.

If the changes are material, we will take reasonable steps to bring them to your attention, such as posting a notice on our website. We encourage you to review this policy periodically so that you remain informed about how we protect your information.

Your continued use of our website after any change becomes effective constitutes your acceptance of the updated policy.
