Heze Changzheng Network Technology Co., Ltd. (referred to in this document as Chang Zheng, we, us, or our) is committed to protecting the privacy of individuals who visit our website at changzheng.lol and who use our computer systems design and integration services. This Privacy Policy explains how we collect, use, disclose, and safeguard your personal information when you interact with our website or engage our services.

We are registered in China at Room 5-3, Building 6, Area C1, Yide City, Kunming Road, West City Subdistrict, Mudan District, Heze City, Shandong Province, 274000. Our data protection practices are designed to comply with applicable data protection laws including the European Union’s General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) where those laws apply to our processing.

We collect information that you provide directly to us. This may include your full name, email address, telephone number, company name, job title, and any other details you submit through our contact form, email correspondence, or service engagement documents.

When you visit our website, we automatically collect certain technical information: your IP address, browser type and version, operating system, referring URLs, page visit timestamps, and interaction patterns. This information is gathered through server logs and analytics cookies. We do not use any third-party analytics services that share your data beyond our control.

If you become a client, we may collect additional business information necessary for project delivery, including system architecture details, network configurations, and technical specifications. This information is processed exclusively for the purpose of delivering the agreed services and is never used for unrelated purposes.

Your personal information is used for the following purposes: to respond to your inquiries and service requests; to negotiate, execute, and perform contracts for systems design and integration services; to send administrative communications regarding our services, policy changes, or account management; to improve our website, services, and client experience through aggregated analysis; and to comply with legal obligations and regulatory requirements.

We do not use your personal information for automated decision-making or profiling that produces legal effects. Where we process data for analytics, we use aggregated and anonymized datasets wherever possible.

If you are located in the European Economic Area, our processing of your personal data is based on the following legal grounds: processing is necessary for the performance of a contract with you or to take steps at your request before entering a contract; processing is necessary for our legitimate interests in operating our business, communicating with clients, and maintaining the security of our systems, provided these interests are not overridden by your data protection rights; processing is based on your consent, which you may withdraw at any time without affecting the lawfulness of processing based on consent before its withdrawal; and processing is necessary for compliance with a legal obligation to which we are subject.

We do not sell your personal information. We do not rent, trade, or otherwise transfer your personal data to third parties for their own marketing purposes.

We may share your information with trusted service providers who assist us in operating our website and business, provided they agree to keep your information confidential and process it only on our instructions. These providers include cloud hosting services, email communication platforms, and payment processors. Each provider is contractually bound to implement appropriate technical and organizational security measures.

We may disclose your information if required by law, legal process, or governmental request; to enforce our contracts or terms of service; or to protect the rights, property, or safety of Chang Zheng, our clients, or others. We will notify you of such disclosure where permitted by law.

Our website uses cookies and similar tracking technologies to enhance your browsing experience and analyze site traffic. Cookies are small text files stored on your device by your web browser.

We use the following types of cookies: essential cookies that are necessary for the website to function properly; analytics cookies that help us understand how visitors interact with our site, enabling us to improve performance and usability; and preference cookies that remember your choices such as language or region settings.

You can control cookie settings through your browser preferences. Disabling certain cookies may affect the functionality of our website. We do not use advertising cookies or third-party tracking cookies for marketing purposes.

We retain your personal information only for as long as necessary to fulfill the purposes for which it was collected, including any legal, accounting, or reporting requirements. Client data related to service delivery is retained for the duration of the contractual relationship plus five years following project completion, after which it is securely deleted or anonymized. Inquiries and contact form submissions are retained for two years unless they lead to an ongoing business relationship. Technical logs and analytics data are retained for a period of twelve months.

We implement appropriate technical and organizational security measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. These measures include: encryption of data in transit using TLS protocols; access controls restricting data access to personnel who require it for their duties; regular security audits and vulnerability assessments; secure data storage in ISO 27001 certified facilities; and employee training on data protection and privacy practices.

While we strive to use commercially acceptable means to protect your data, no method of transmission over the Internet or electronic storage is 100% secure. We cannot guarantee absolute security but will notify you of any data breach affecting your personal information within 72 hours of discovery where we are legally required to do so.

Depending on your location, you may have the following rights regarding your personal information: the right to access the personal data we hold about you and request a copy; the right to rectify inaccurate or incomplete data; the right to request deletion of your personal data where there is no compelling reason for its continued processing; the right to restrict processing under certain circumstances; the right to data portability to receive your data in a structured, commonly used, machine-readable format; the right to object to processing based on legitimate interests or for direct marketing purposes; and the right to withdraw consent at any time where processing is based on consent.

For California residents under the CCPA, you additionally have the right to know what personal information we collect, use, and disclose; the right to request deletion of your personal information; the right to opt out of the sale of your personal information (we do not sell personal information); and the right to non-discrimination for exercising your privacy rights.

To exercise any of these rights, please contact us at can@changzheng.lol. We will respond to your request within 30 days. We may need to verify your identity before processing your request.

Our services are not directed to individuals under the age of 16. We do not knowingly collect personal information from children. If we become aware that a child under 16 has provided us with personal data, we will take steps to delete such information promptly. If you believe that a child has provided us with personal information, please contact us immediately.

As a company operating in China with clients in North America and Europe, your personal information may be transferred to and processed in countries other than your own. When we transfer personal data from the European Economic Area to countries that the European Commission has not deemed adequate, we rely on appropriate safeguards such as Standard Contractual Clauses approved by the European Commission. We take reasonable steps to ensure that any international transfer of your personal data is protected by appropriate safeguards.
