Effective date: September 4, 2026 · Applies to https://www.chengzhennet.buzz
This Privacy Policy explains how Songyuan Chengzhen Network Technology Co., Ltd. collects, uses, protects, and shares information when you visit https://www.chengzhennet.buzz, contact the studio, or engage the services described on this website. The website and the services offered through it are developed and operated by the developer Cheng Zhen Net. We take the responsibility of handling your information seriously, and this document describes our practices in plain and complete terms so that you can make informed decisions.
Songyuan Chengzhen Network Technology Co., Ltd. is a computer integrated systems design company registered in Songyuan, China, operating within the Professional, Scientific, and Technical Services sector. The studio plans, builds, and maintains computer systems, network infrastructure, custom software, and cloud integration for businesses of many sizes.
Our registered office is located at Room B0231, 4th Floor, No.102 Building 2, Commercial Complex, Boxue Road, Ningjiang District, Songyuan - 131000, China (CN). For the purposes of applicable data protection law, Songyuan Chengzhen Network Technology Co., Ltd. acts as the controller of personal information described in this policy. You can reach us at care@chengzhennet.buzz or by telephone at +14472639207.
This policy applies to information gathered through our website, through email and telephone correspondence with the studio, and through the delivery of professional services to clients. It covers visitors who browse the site, prospective clients who send inquiries, existing clients, suppliers, and job applicants who contact us.
This policy does not apply to websites, products, or services operated by third parties, even when we link to them from our pages. When you leave our website, the practices of the destination operator govern your information, and we encourage you to read the privacy notices of every site you visit.
We collect several categories of information depending on how you interact with the studio. The main categories are:
We do not intentionally collect special categories of personal information, such as health data, biometric data, or information about political opinions, and we ask that you do not send such material to us unless it is strictly necessary for a lawful engagement.
We collect information in three principal ways. First, we collect information directly from you when you fill in the contact form on our website, write to us by email, call the studio, or meet our engineers on site. Second, we collect technical information automatically as you browse the website, through server logs and standard measurement tools that record how pages are accessed. Third, we may receive information from third parties, such as a client who adds you as a contact person for a project, or a referral partner who passes on your inquiry.
The amount of information we request is limited to what is reasonably necessary. For a simple inquiry, a name, an email address, and a short message are usually enough. For project work, we may ask for more detailed material, and we will always explain why it is needed before we ask for it.
Cookies are small text files that a website stores on your device. Our website uses a minimal set of cookies and similar technologies for two purposes: to keep the site functioning correctly and to understand, in aggregate, how visitors use the pages so that we can improve them.
Strictly necessary cookies support basic functions such as security and load balancing. Measurement cookies, when enabled, help us count visits and page views without building personal profiles of individual visitors. You can control cookies through your browser settings, where you can block or delete them at any time. Blocking strictly necessary cookies may affect parts of the website, while blocking measurement cookies will not reduce any functionality available to you.
We use the information we collect for the following purposes:
We do not use personal information for automated decision-making that produces legal effects concerning individuals. When a purpose requires information beyond what the original collection covered, we will seek your consent before proceeding.
Where data protection law requires a legal basis for processing, we rely on the following grounds. Performance of a contract applies when processing is necessary to deliver services you have engaged, such as preparing a proposal or operating a client network. Legitimate interests apply when we use information to improve the website, secure our systems, and keep business records, in ways that visitors and clients can reasonably expect. Consent applies when you voluntarily subscribe to updates or agree to optional measurement cookies, and you may withdraw that consent at any time. Legal obligation applies when we must retain records for tax, accounting, or regulatory purposes.
We balance our legitimate interests against the rights and expectations of the individuals concerned. If you wish to object to processing based on legitimate interests, you may contact us using the details in the final section of this policy, and we will review your request.
We measure the performance of our website to keep it fast, reliable, and useful. Measurement is based on aggregated and anonymized statistics, such as the number of visits per page, the average time spent on the site, the browser families in use, and the approximate regions from which visits originate. These statistics do not identify individual visitors and are not combined with contact records in a way that builds behavioral profiles.
Server logs are kept to diagnose faults, prevent abuse, and plan capacity. Log entries are rotated and deleted on a fixed schedule, and access to them is restricted to the engineers who maintain the site. We do not sell analytics data to anyone.
Performance measurement also helps us honor the reliability figures we publish. Uptime, response times, and incident counts are tracked for the systems the studio operates, and the summaries shown on this website reflect the same measurement discipline. Individuals who prefer that their visits not be measured can use private browsing modes or cookie controls described in the sections above without losing any core functionality.
Like most studios, we rely on trusted providers for certain functions, such as website hosting, email delivery, cloud storage, and accounting software. These providers process information on our behalf and only under written agreements that restrict them from using the information for their own purposes.
We select providers with care, review their security practices, and keep the list as short as practical. When a provider changes or a contract ends, we require the safe return or deletion of the information entrusted to that provider. A current list of the categories of providers we use is available on request to care@chengzhennet.buzz.
We do not sell personal information, and we do not rent or trade contact lists. Information is shared outside the studio only in the following limited situations: with service providers acting under contract, as described above; with professional advisers, such as auditors and lawyers, who are bound by confidentiality; with a client organization when you are a named contact for that engagement and the sharing is necessary for the work; and with public authorities when the law requires disclosure or when disclosure is necessary to protect the rights, property, or safety of the studio, our clients, or the public.
If the studio ever undergoes a reorganization or transfer of business, we will require any successor to honor the commitments in this policy, and we will notify affected individuals where required by law.
The studio operates in China, and our providers may store or process information in other countries. Where information crosses borders, we take steps to ensure that it receives an adequate level of protection, including contractual safeguards with providers, encryption during transmission, and access controls that limit who can read the data.
Before engaging a provider located in another region, we review the legal environment of the destination, the sensitivity of the information involved, and the practical effect of the safeguards in place. If the review raises doubts, we select a different provider or keep the processing inside the country. The steps we take are recorded internally so that any client or visitor can be told, on request, how their information is protected when it travels.
The rules that protect your information travel with it. Regardless of where processing takes place, we apply the standards described in this policy to all information we handle, and we comply with applicable cross-border transfer requirements.
We keep personal information only as long as necessary for the purposes described in this policy and for the periods required by law. Inquiry correspondence is retained for up to twenty-four months so that we can follow up properly and reference earlier discussions. Project and contract records, including invoices and delivery documents, are retained for the period required by accounting and tax regulations, which is generally several years after the end of a financial year. Server logs are kept for a short rotation window of up to ninety days.
When information is no longer needed, we delete it securely or anonymize it so that it can no longer be associated with any individual. Backup copies are overwritten on the normal backup cycle, and we document our retention practices internally so that the schedule is followed consistently.
We apply technical and organizational measures appropriate to the sensitivity of the information we hold. Measures include encryption of data in transit using current transport security, access controls based on roles and least privilege, network segmentation between office and production systems, regular patching of servers and workstations, and secure disposal of retired equipment.
Our engineers follow written procedures for handling incidents, and any suspected breach of personal information is investigated promptly. Where a breach is likely to affect your rights, we will notify you and the competent authorities within the timeframes required by applicable law, and we will describe the measures taken to address the incident.
No method of transmission or storage is completely secure. While we work hard to protect your information, we cannot guarantee absolute security, and we encourage sensible practices on your side, such as guarding access to your own email accounts.
Depending on your location and applicable law, you may have one or more of the following rights over your personal information:
To exercise any of these rights, write to care@chengzhennet.buzz or call +14472639207. We may ask for reasonable details to verify identity before acting on a request. We aim to respond within thirty days of a verified request. If you are not satisfied with our response, you may have the right to complain to a competent supervisory authority in your jurisdiction.
Our website and services are directed at businesses and professional users. We do not knowingly collect personal information from children under the age of sixteen. If you believe that a child has sent us personal information, please contact us at care@chengzhennet.buzz, and we will delete the material promptly once the report is verified.
School and family users who encounter our services through a parent organization or a school program should work through the responsible adult who manages that relationship. We are glad to explain our practices to guardians and administrators at any time, and we will cooperate with a parent or guardian who asks us to remove information that a minor has provided.
We send marketing messages only to individuals and organizations with whom we have an existing relationship or who have asked to hear from us. Messages are limited in frequency, always identify the studio, and include a simple way to stop further mail. You may opt out of marketing at any time by replying with an opt-out request or by writing to care@chengzhennet.buzz.
Administrative messages about an active engagement, such as appointment confirmations, security notices, and delivery updates, are not marketing, and they continue for the duration of the work because they are necessary for the service.
Our website may contain links to third-party sites, such as technology vendors, standards bodies, and public resources. Those sites operate under their own privacy notices, and we have no control over their practices. We encourage you to review the policies of any site before providing personal information to it.
We choose outbound links with care and favor organizations with published privacy commitments. Links are provided for convenience and information only, and a link is not an endorsement of every practice or statement on the destination site. If you find that a link from our website leads to a page with harmful or misleading practices, please tell us at care@chengzhennet.buzz and we will review and remove it where appropriate.
Where a third-party tool is embedded in our pages, such as a map or a document viewer, its provider may receive technical information about your device as part of delivering the content. We keep such embeds to a minimum and choose providers with reasonable privacy practices.
We may update this policy from time to time to reflect changes in the law, in our services, or in our practices. The current version is always published on this page, and the effective date at the top of the document shows when it was last revised. If a change is significant, we will add a clear notice on the website homepage for a reasonable period.
Continued use of the website after a revision takes effect means that you accept the updated policy. If you disagree with a change, you may stop using the website and contact us about information we hold.
If you have questions about this policy, about the information we hold, or about how the studio handles privacy, please contact us by any of the following channels:
We answer privacy requests and questions within one business day where possible, and within thirty days at the latest for formal rights requests.
