This Privacy Policy explains in detail how we collect, process, store, share, and safeguard personal information obtained through our website located at https://www.supportdun.buzz, through our service delivery channels, and through any other interactions you may have with our organization. Zhijiang Fudun Trading Co., Ltd. maintains its registered office at No. 2, Front of Building 2, Wutongmiao Village, Xianv Town, Zhijiang 443200, China, and operates under the trade brand Support Dun.

By accessing our website or using our services, you acknowledge that you have read and understood this Privacy Policy and you agree to the collection and use of your information in accordance with the terms described herein. If you do not agree with any part of this policy, we kindly ask that you refrain from using our website and services. We encourage you to review this document thoroughly and to contact us with any questions you may have before proceeding. Our commitment to transparency means we have structured this policy to be comprehensive, clear, and accessible, covering every aspect of our data handling practices.

2. Information We Collect

In the course of providing integrated computer systems design, managed IT infrastructure, network architecture, cloud integration, technical consulting, and system diagnostics services, we may collect several categories of information. The information we gather depends on the nature of your interaction with us — whether you are browsing our website, submitting a contact form, requesting a consultation, signing a service agreement, or receiving ongoing support. We classify the information we collect into the following principal categories.

Personal Identification Information. When you complete our contact form, request a consultation, or otherwise communicate with us directly, we may collect your full name, email address, telephone number, company or organizational affiliation, job title, and physical or postal address. This information enables us to respond to your inquiries, prepare proposals, verify your identity when necessary, and maintain accurate records of our professional relationship with you. We collect only the personal identification information that is reasonably required for the specific purpose of your interaction with us.

Technical and Usage Information. When you visit our website, our servers automatically record certain technical data transmitted by your browser or device. This may include your Internet Protocol (IP) address, browser type and version, operating system, referring URL, pages visited on our website, the date and time of your visit, time spent on individual pages, click patterns, and other diagnostic data. We use this information to analyze website performance, detect and prevent technical issues, understand aggregate usage trends, and improve the functionality and content of our website. This data is typically collected in an anonymized or pseudonymized form and is not used to identify individual visitors unless combined with other identifying information for a specific lawful purpose.

Service-Related Information. When you engage Support Dun for systems design, infrastructure management, or technical consulting services, we may collect and process information related to your existing technology environment. This can include hardware inventories, software configuration details, network topology maps, system architecture documents, performance metrics, security audit findings, and other technical data necessary for us to assess, design, implement, and support your integrated systems. We treat all service-related information as confidential and process it strictly within the scope of our engagement agreement with you.

Communication Records. We may retain copies of correspondence exchanged between you and Support Dun, including emails, contact form submissions, telephone call summaries, meeting notes, and support ticket communications. These records help us maintain continuity in our professional relationship, track the progress of ongoing projects, respond to follow-up inquiries efficiently, and comply with any applicable legal or regulatory record-keeping obligations.

3. How We Use Information

Support Dun uses the information we collect for a defined set of purposes, all of which are directly connected to the delivery of our professional services, the operation and improvement of our website, and compliance with legal obligations. We do not use your personal information for purposes that are incompatible with the original reasons for which it was collected, and we do not engage in automated decision-making or profiling that produces legal effects concerning you.

The primary uses of your information include delivering and managing the services you have requested from us, responding to inquiries and providing customer support, preparing and sending proposals, contracts, invoices, and service documentation, maintaining and improving the functionality and security of our website, analyzing aggregate usage patterns to inform business decisions, sending administrative communications related to your account or our services, complying with applicable laws, regulations, and legal processes, and protecting the rights, property, and safety of Support Dun, our clients, and the public. We may also use anonymized and aggregated data derived from the information we collect for research, analytics, and service development purposes, provided that such data cannot reasonably be used to identify any individual.

4. Legal Bases for Processing

Support Dun processes personal information in accordance with applicable data protection laws, including the relevant legal frameworks of the People Republic of China where our registered entity is established. The legal bases on which we rely for processing your personal information depend on the nature of the data and the specific context in which we collect it.

In most cases, we process your personal information based on one or more of the following legal grounds: the performance of a contract with you or the taking of steps at your request before entering into a contract, such as when we prepare a service proposal or deliver systems integration services under a signed agreement; our legitimate business interests, which include operating and improving our website, responding to inquiries, maintaining business records, and ensuring the security of our systems, provided that such interests are not overridden by your data protection rights; compliance with a legal obligation to which we are subject, such as tax record-keeping or responding to lawful requests from regulatory authorities; and your consent, where we have specifically requested and obtained your consent for a particular processing activity, such as sending marketing communications where required by law. You have the right to withdraw your consent at any time, though such withdrawal will not affect the lawfulness of processing carried out before the withdrawal.

5. Data Sharing and Disclosure

Support Dun does not sell, rent, trade, or otherwise disclose your personal information to third parties for their own marketing or commercial purposes. We share your information only in the limited circumstances described below and always subject to appropriate safeguards designed to protect your privacy.

We may share your information with trusted service providers and subcontractors who perform functions on our behalf and under our instruction. These may include cloud hosting providers, email delivery services, analytics platforms, payment processors, and professional advisors such as legal counsel and accountants. We require all such third parties to process your information only in accordance with our documented instructions, to implement appropriate technical and organizational security measures, and to comply with confidentiality obligations equivalent to those set forth in this policy.

We may disclose your information if required to do so by law or in response to a valid and enforceable request from a government authority, regulatory agency, or court of competent jurisdiction. We may also disclose information where we believe in good faith that such disclosure is necessary to protect our rights, enforce our terms of service, investigate potential violations, detect or prevent fraud or security incidents, or protect the personal safety of our staff, our clients, or members of the public. In the event that Zhijiang Fudun Trading Co., Ltd. is involved in a merger, acquisition, restructuring, or sale of all or a portion of its assets, your information may be transferred as part of that transaction, subject to the same privacy commitments described in this policy or under a successor policy that provides at least equivalent protection.

6. Cookies and Tracking Technologies

Our website uses cookies and similar tracking technologies to enhance your browsing experience, analyze website traffic, and understand how visitors interact with our content. A cookie is a small text file that is placed on your device by your web browser at the direction of the websites you visit. Cookies allow a website to recognize a returning browser and to remember certain preferences or settings from previous visits.

We use session cookies, which expire when you close your browser, to maintain the continuity of your visit and to enable essential website functions such as form submissions. We also use persistent cookies, which remain on your device for a defined period, to remember preferences and to support our analytics efforts. The analytics cookies we deploy help us measure aggregate metrics such as page views, visit duration, traffic sources, and user navigation paths. This information is collected in a form that does not directly identify individual visitors. You have the ability to control and manage cookies through your browser settings at any time. Most browsers allow you to block cookies, delete existing cookies, or receive a warning before a cookie is stored. Please note that disabling cookies may affect the functionality of certain features on our website. By continuing to use our website without changing your cookie settings, you consent to our use of cookies as described in this section.

7. Data Retention

Support Dun retains your personal information only for as long as is necessary to fulfill the purposes for which it was collected, to satisfy any legal, accounting, or regulatory reporting requirements, or to resolve disputes and enforce our agreements. The specific retention period for each category of information is determined by reference to the nature and sensitivity of the data, the potential risk of harm from unauthorized use or disclosure, the purposes for which we process the data, and any applicable legal retention obligations.

As a general guideline, we retain contact form submissions and correspondence for a period of up to three years following the conclusion of our last communication with you, unless a longer retention period is required by law or is necessary in connection with an ongoing contractual relationship. Service-related technical data is retained for the duration of our engagement plus a reasonable period thereafter, as specified in the applicable service agreement. Website usage data collected through analytics is typically retained in aggregate form for up to twenty-six months. When the applicable retention period expires, we securely delete or anonymize your personal information so that it can no longer be associated with you. In some circumstances, you may request earlier deletion of your data as described in Section 11 of this policy.

8. Data Security

We implement and maintain appropriate technical and organizational security measures designed to protect your personal information against accidental or unlawful destruction, loss, alteration, unauthorized disclosure, or access. Our security practices are informed by industry standards and are regularly reviewed and updated to address evolving threats and vulnerabilities.

The measures we employ include the use of encrypted data transmission protocols for data in transit, secure server environments with access controls for data at rest, network-level protections including firewalls and intrusion detection systems, regular vulnerability assessments and security patch management, role-based access controls that limit data access to authorized personnel who require it for their duties, and ongoing security awareness training for our staff. Despite our best efforts, no method of electronic transmission or storage is entirely immune to security risks. While we strive to protect your personal information using commercially reasonable means, we cannot guarantee its absolute security. In the unlikely event of a data breach involving your personal information, we will notify you and the relevant authorities in accordance with applicable legal requirements.

9. International Data Transfers

Support Dun is based in the People Republic of China, and our primary data processing activities occur within China. However, in the course of delivering our services and operating our website, your personal information may be transferred to, stored, or processed in other countries where our service providers or subcontractors maintain facilities. These countries may have data protection laws that differ from those in your country of residence.

Whenever we transfer personal information across national borders, we take steps to ensure that the information receives an adequate level of protection in the destination country. These steps may include entering into data processing agreements that incorporate standard contractual clauses approved by relevant regulatory authorities, verifying that the recipient jurisdiction offers an adequate level of data protection as determined by applicable law, or implementing supplementary technical and organizational measures as needed. By using our website or engaging our services, you consent to the transfer of your information to countries outside your country of residence, including to China and to any other jurisdiction where we or our service providers operate, subject to the safeguards described in this section.

10. Privacy for Children

The website and services of Support Dun are designed for business professionals, organizations, and enterprises. They are not directed at, intended for, or marketed to individuals under the age of eighteen. We do not knowingly collect, solicit, or process personal information from children. If we become aware that a child under the age of eighteen has provided us with personal information without verifiable parental consent, we will take prompt steps to delete such information from our systems.

If you are a parent or legal guardian and you believe that your child has submitted personal information to us, we encourage you to contact us immediately using the contact details provided in Section 14 below. Upon verification of your identity and your relationship to the child, we will work with you to identify and remove any such information from our records. We also recommend that parents and guardians actively monitor the online activities of children in their care and educate them about the importance of protecting personal information when using the internet.

11. Your Rights and Choices

Depending on your jurisdiction of residence and the applicable data protection legislation, you may have a number of rights concerning the personal information we hold about you. Support Dun is committed to facilitating the exercise of these rights to the fullest extent required by law. We describe below the principal rights that may be available to you, along with how you can exercise them.

Right of Access. You have the right to request confirmation from us as to whether we are processing your personal information and, if so, to obtain a copy of that information along with details about the purposes of processing, the categories of data concerned, and the recipients or categories of recipients to whom the data has been or will be disclosed.

Right to Rectification. You have the right to request that we correct any inaccurate personal information we hold about you and to have incomplete information completed, including by means of providing a supplementary statement. We encourage you to keep your contact details and other information current so that we can serve you effectively.

Right to Erasure. You may have the right to request that we delete your personal information in certain circumstances, such as when the data is no longer necessary for the purposes for which it was collected, when you withdraw your consent and no other legal ground for processing exists, or when the data has been processed unlawfully. This right is subject to certain exceptions, including where retention is required for compliance with a legal obligation or for the establishment, exercise, or defense of legal claims.

Right to Restrict Processing. You may have the right to request that we limit the processing of your personal information in specific situations, such as when you contest the accuracy of the data, when the processing is unlawful and you oppose erasure, or when we no longer need the data but you require it for a legal claim.

Right to Data Portability. Where processing is carried out by automated means and is based on your consent or on a contract, you may have the right to receive your personal information in a structured, commonly used, and machine-readable format and to have that data transmitted directly to another data controller where technically feasible.

Right to Object. You may have the right to object, on grounds relating to your particular situation, to the processing of your personal information that is based on our legitimate interests. You may also have the right to object to processing for direct marketing purposes at any time, and we will cease such processing promptly upon receiving your objection.

Right to Withdraw Consent. Where our processing of your personal information is based on your consent, you have the right to withdraw that consent at any time. Withdrawal of consent does not affect the lawfulness of processing that occurred before the withdrawal.

To exercise any of the rights described above, please contact us using the details provided in Section 14. We will respond to your request within the time frame required by applicable law, typically within thirty days of receiving a verified request. We may need to verify your identity before processing your request, and we reserve the right to charge a reasonable fee or refuse to act on requests that are manifestly unfounded or excessive. You also have the right to lodge a complaint with the relevant data protection supervisory authority in your jurisdiction if you believe that our processing of your personal information violates applicable law.
