Effective date: 1 January 2026
This Privacy Policy describes how Nanchong Du Ao Chen E-commerce Co., Ltd. (referred to in this document as the Company, we, us, or our) handles personal information when you visit our website at www.duaocheng.buzz, contact our team, or use the services we offer. Please read this policy carefully before you share any personal information with us.
1. Introduction
This Privacy Policy explains how Nanchong Du Ao Chen E-commerce Co., Ltd. (referred to in this document as the Company, we, us, or our) collects, uses, discloses, and protects information when you visit our website at www.duaocheng.buzz or use any of the services we provide. The services described on this website are developed and operated by the developer DuAoCheng on behalf of the Company, and all questions about the way your data is handled should be directed to us using the contact details set out at the end of this policy.
We respect your privacy and are committed to handling your personal information with transparency and care, in line with the data protection laws of the regions in which we operate. By accessing our website or engaging our services, you acknowledge that you have read and understood the practices described in this policy. If you do not agree with any part of this policy, please do not use our website or our services.
This policy applies to information collected online through our website and to information that you provide to us through email, telephone, or in person during the course of a project. It also applies to information that a client shares with us about their own customers and staff when we are engaged to design, integrate, or operate a system on their behalf.
2. Scope of This Policy
This policy covers the personal information that we handle as a data controller, which means that we decide how and why your information is used. It applies to visitors of our website, to prospective clients who contact us through the contact form or by other means, to current clients who have signed an agreement with us, and to individuals whose information may be processed on behalf of a client during the delivery of a project.
Personal information means any information that relates to an identified or identifiable natural person. This includes obvious identifiers such as your name and email address, and it also includes less obvious information such as your Internet Protocol address when it can be linked back to you.
The policy does not apply to information processed by third parties that we do not control, nor to the practices of companies that we do not own or manage. Where we process data on behalf of a client under a separate agreement, that agreement together with the client instructions will govern our processing, and this policy applies only to the extent that it does not conflict with those instructions. In all cases, we try to collect only the information that is necessary for the purpose for which it is used.
3. Information We Collect
We collect information in three broad categories. First, information that you provide directly, such as your name, company name, email address, telephone number, job title, and the content of messages that you send through our contact form or by email. We use this information to respond to your enquiry and to assess whether our services are a good fit for your needs.
Second, information that we collect automatically when you visit our website, including your Internet Protocol (IP) address, browser type, operating system, referring web page, pages viewed, time spent on the site, and similar technical data gathered through cookies and server logs. This information helps us keep the website stable and understand how visitors use it.
Third, information that we collect during a project, including business requirements, system specifications, technical documentation, project files, and any other material that you share with us for the purpose of delivering the agreed services. We do not collect sensitive categories of personal information unless you voluntarily provide it and it is strictly necessary for a project that you have asked us to perform.
4. How We Use Your Information
We use the information we collect for a limited number of clear purposes, and we do not expand these purposes without telling you. We use your contact details to respond to enquiries, to schedule consultations, to prepare proposals and contracts, and to keep you informed about the progress of your project from scoping to delivery and beyond.
We use technical data to maintain and improve the performance, security, and usability of our website, and to understand how visitors find and navigate our content so that we can make the site more useful. We use project information to design, build, integrate, and operate the systems that are the subject of our agreements, and to provide support and maintenance after delivery.
We may use aggregated and anonymised data that cannot identify you for internal reporting, research, and quality improvement. We do not sell your personal information, and we do not use it for marketing purposes unless you have given us clear permission to do so. Where we contact you about related services, we always give you a simple way to opt out.
5. Legal Bases for Processing
Where the General Data Protection Regulation or a similar law applies to you, we rely on several lawful bases to process personal information. We process information to perform a contract with you, for example when we deliver services described in a signed agreement or when we respond to pre-contractual enquiries at your request.
We process information where you have given consent, for example when you agree to receive communications from us, and you may withdraw that consent at any time using the contact details below. We process information where it is necessary for our legitimate interests, such as operating our website securely, preventing fraud, improving our services, and responding to enquiries, provided that our interests do not override your rights and freedoms.
We also process information to comply with legal obligations, such as accounting, tax, and regulatory requirements. When we rely on a particular basis, we apply the one that is most appropriate to the situation and to the nature of the data involved, and we keep a record of our reasoning so that we can demonstrate our compliance if asked.
8. International Data Transfers
The Company is registered in China, and some of our service providers may store or process data in countries other than your own. Where we transfer personal information across borders, we take steps to ensure that the information continues to receive an adequate level of protection, whichever country it is held in.
We do this by relying on approved transfer mechanisms, such as standard contractual clauses adopted by the relevant authorities, or by confirming that the destination country offers an adequate level of protection under applicable law. Where required by law, we will inform you about the specific safeguards that are in place for a particular transfer.
The Internet is global by nature, and data that you send to us may pass through servers in several countries before it reaches us. By using our website and services, you understand and accept that your information may be processed in locations outside your country of residence, in accordance with the safeguards described in this section. If the legal framework changes and a transfer mechanism is invalidated, we will promptly review the transfer and apply an alternative safeguard.
9. Data Retention Practices
We retain personal information only for as long as necessary to fulfil the purposes for which it was collected, or for as long as we are required to keep it by law. Contact enquiries are kept for a reasonable period so that we can follow up, maintain a record of our correspondence, and answer any questions that you raise later.
Information related to an active project is retained for the duration of the engagement and for a reasonable period afterwards to support warranties, ongoing support obligations, and record-keeping requirements. Accounting and tax records are retained for the period required by applicable financial regulations, which is often several years.
When information is no longer needed for any of these purposes, we delete it or anonymise it so that it can no longer be linked to you. We review our retention periods regularly, and we apply the shortest period that is consistent with our legal and business obligations. Copies of data held in backup systems are deleted according to the same principles as soon as it is technically possible.
10. Data Security Measures
We take the security of your information seriously and apply appropriate technical and organisational measures to protect it throughout its lifecycle. These measures include encryption of data in transit, restricted access to systems based on the principle of least privilege, strong authentication for our staff, and regular security reviews of our infrastructure.
We maintain backups designed to protect against accidental loss, and we test our recovery procedures so that we can restore service quickly if something goes wrong. Access to personal information is limited to employees and contractors who need it to perform their duties, and every one of them is bound by confidentiality obligations that continue after the working relationship ends.
While no method of transmission over the Internet and no method of electronic storage is completely secure, we work continuously to maintain the integrity and security of our systems. If a data breach occurs that is likely to result in a risk to your rights and freedoms, we will notify you and the relevant supervisory authority in accordance with applicable law, and we will tell you what we are doing to respond.
11. Privacy for Children
Our website and services are not directed to children, and we do not knowingly collect personal information from children. For the purpose of this policy, a child is an individual who has not reached the age of sixteen, or the higher age threshold that applies in their country of residence.
If we learn that we have collected personal information from a child without verified parental consent, we will delete that information promptly and take reasonable steps to prevent it from being collected again. If you believe that a child has provided us with personal information, please contact us using the details at the end of this policy so that we can take the appropriate action.
We encourage parents and guardians to supervise their children when they are online and to be aware of the websites their children visit. We will never knowingly market our services to children, and we will never encourage children to provide us with any personal information through games, quizzes, or similar features.
12. Your Rights and Choices
Depending on the law that applies to you, you may have the right to access the personal information we hold about you, to request that it be corrected if it is inaccurate, and to request its deletion. You may also have the right to object to certain processing, to request that processing be restricted, and to request a copy of your information in a structured, machine-readable format.
Where we process information on the basis of your consent, you may withdraw that consent at any time without affecting the lawfulness of processing that was carried out before the withdrawal. Where we process information on the basis of our legitimate interests, you may object to that processing, and we will stop unless we can demonstrate compelling legitimate grounds that override your interests.
To exercise any of these rights, please contact us using the details provided at the end of this policy. We will respond to verified requests within the time period required by law, and we may extend that period for complex requests after telling you why. We may ask you to verify your identity before we process your request, and we will never discriminate against you for exercising your privacy rights.
13. Third-Party Links and Services
Our website may contain links to external websites and services that are not operated by us, such as the websites of our partners, industry publications, and professional networks. We do not control these third-party websites, and this Privacy Policy does not apply to information that you provide to them.
When you leave our website, we encourage you to read the privacy policy of the destination site so that you understand how it collects and uses your information. The inclusion of a link does not imply any endorsement of the linked website or of its practices, and we are not responsible for the privacy practices or the content of any third-party websites.
If you follow a link and provide personal information on an external site, that information is governed by the policies of the external site, not by this policy. Please exercise caution and review the applicable policies before you provide personal information on any external site, particularly if the site asks for financial details or login credentials.
14. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, in technology, or in legal requirements. When we make changes, we will revise the effective date at the top of this page, and the updated policy will apply to all information that we hold at the time it is posted.
If we make changes that materially affect the way we use your personal information, we will take reasonable steps to notify you, including by placing a notice on our website or by contacting you directly where appropriate. Material changes include new uses of your data, new categories of data collected, and new sharing arrangements.
We encourage you to review this page periodically so that you are always aware of how we handle your information. Your continued use of our website or services after the posting of a revised policy constitutes acceptance of the revised terms, and the version in force at the time of your interaction will apply to that interaction.
