Privacy Policy

1. Introduction

Welcome to the QianEr website, which is operated by Shaanxi Qianer Dukun Network Technology Co., Ltd. (陕西千儿杜坤网络科技有限公司). We are a company engaged in computer systems design and related services, specializing in computer integrated systems design within the broader professional, scientific and technical services sector. This Privacy Policy applies to all information we collect when you visit our website, contact us by email or telephone, or engage our services.

We are committed to handling your personal information with care, transparency and respect. This document is written to be easy to understand while still covering the legal detail that modern privacy regulation requires. Please read it carefully. If you do not agree with any part of this policy, you should stop using our website and contact us so we can address your concerns.

The term personal information as used in this policy means any data that can identify you as an individual, either directly or indirectly. This includes your name, email address, telephone number, and technical identifiers such as your IP address.

We recognize that trust is earned through consistent and predictable behavior. For that reason, we have structured this policy around clear commitments: we collect less, we explain more, we keep data only as long as needed, and we give you meaningful control over your information. These commitments apply equally to a first time visitor reading a blog post and to a long term client who has trusted us with the design of their core systems.

2. Information We Collect

We collect several categories of information depending on how you interact with us. We keep our collection to the minimum needed to provide a professional and responsive service.

2.1 Information You Provide Directly

• Contact information such as your full name, email address and telephone number when you fill out our contact form or reach us by email or phone.
• The content of any message, inquiry or project description you send to us.
• Information you provide when you request a quote, schedule a consultation or engage our services.

2.2 Information Collected Automatically

When you visit our website, our servers may automatically record technical information about your device and your visit, including your IP address, browser type, operating system, the pages you viewed, the date and time of your visit, and the website that referred you to us. This data is used to keep the site secure, diagnose technical problems and understand how visitors use the site.

2.3 Information We Do Not Collect

We do not collect sensitive categories of personal data such as financial account numbers, government identification numbers, health information or biometric data. We also do not deliberately collect information about your precise location or your browsing activity on other websites.

We do not purchase personal information from data brokers, and we do not compile dossiers of personal information about our visitors. If you simply read the pages of this website without submitting a form or sending us a message, the only information we hold about you is the routine technical data described above, and we use it purely to keep the site secure and running smoothly.

3. How We Use Your Information

We use the information we collect for the following purposes, each tied to operating our business and serving you better.

• To respond to your inquiries and provide the information or services you request.
• To prepare proposals, quotes and project plans for prospective engagements.
• To fulfill contractual obligations when you engage our computer systems design or integration services.
• To improve our website, services and customer experience based on aggregate usage patterns.
• To maintain the security and integrity of our website and systems, including detecting and preventing fraud or abuse.
• To comply with applicable legal obligations, such as record keeping and tax requirements.

We do not use your personal information to make automated decisions that have legal or similarly significant effects on you, and we do not build profiles of you for advertising purposes.

We may also aggregate and de-identify information so that it can no longer be linked to you. Aggregate data helps us understand broad trends, such as which services are requested most often or which regions our visitors come from. Because this data cannot reasonably be used to identify any individual, it is not treated as personal information under this policy.

4. Legal Bases for Processing

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

4.1 Consent

When you voluntarily submit information through our contact form or otherwise contact us, you consent to us using that information to respond to you.

4.2 Contractual Necessity

We process information when it is necessary to perform a contract with you or to take steps at your request before entering into a contract, such as preparing a proposal.

4.3 Legitimate Interests

We process limited technical information based on our legitimate interest in operating a secure and effective website, provided that such interests are not overridden by your rights and freedoms.

4.4 Legal Obligation

We process information when we are required to do so by applicable law or regulation.

5. Cookies and Tracking Technologies

Our website uses cookies and similar technologies to function correctly and to understand how visitors use our site. A cookie is a small text file stored on your device by your browser.

5.1 Types of Cookies We Use

• Essential cookies that are necessary for the website to function, such as remembering basic preferences.
• Analytics cookies that help us measure traffic and understand which pages are most useful to visitors.

5.2 Managing Cookies

Most browsers allow you to control or delete cookies through their settings. You can block all cookies if you prefer, although doing so may limit some functionality of the website. You can also use the settings in your browser to clear cookies at any time.

6. How We Share Information

We do not sell, rent or trade your personal information to any third party. We share information only in the limited circumstances described below.

• With service providers who help us operate our website and business, such as hosting and email providers, under strict confidentiality obligations.
• With professional advisers such as lawyers and accountants where necessary to protect our legal interests.
• With regulators, law enforcement or other authorities when we are required to do so by law or in response to a valid legal request.
• With a successor entity in the event of a merger, acquisition or sale of all or part of our business, provided the successor agrees to honor this policy.

7. Third Party Services

Our website may contain links to third party websites or services that are not operated by us. This Privacy Policy does not apply to those third parties. We encourage you to review the privacy policies of any third party website or service before providing information to them. We are not responsible for the privacy practices or content of websites we do not control.

If we engage third party processors to handle personal information on our behalf, we select providers who offer appropriate safeguards and we put in place contractual terms that require them to protect your data.

8. Data Retention

We retain personal information only for as long as is necessary to fulfill the purposes described in this policy, unless a longer retention period is required or permitted by law. The specific retention period depends on the type of information and the purpose for which it was collected.

For example, inquiry messages are typically retained for up to twenty four months after our last correspondence, while information necessary to fulfill a contract may be retained for the duration of the contract plus any period required by tax or accounting law. When information is no longer needed, we delete it or anonymize it in a secure manner.

We review our retention schedule on a regular basis to make sure we are not holding information longer than necessary. When a retention period expires, we either permanently erase the information or convert it into a form that no longer identifies any individual. Backups and archived systems are handled under the same schedule so that deleted information does not linger in secondary copies.

9. Data Security

We implement reasonable and appropriate technical and organizational measures to protect personal information against accidental loss, unauthorized access, alteration, disclosure or destruction. These measures include encrypted connections, access controls, and regular review of our security practices.

Access to personal information within our organization is limited to personnel who need it to perform their duties, and those personnel are bound by confidentiality obligations. We apply the principle of least privilege, meaning each team member can access only the data required for their specific role. We also keep logs of access to sensitive systems and review those logs for unusual activity.

While we work hard to protect your information, no method of transmission over the internet or method of electronic storage is completely secure. We cannot guarantee absolute security, but we are committed to responding promptly to any security incident and to notifying affected individuals where required by law.

10. Your Privacy Rights

Depending on your location, you may have certain rights regarding your personal information. These rights may include the following.

• The right to access the personal information we hold about you.
• The right to request correction of inaccurate or incomplete information.
• The right to request deletion of your personal information, subject to legal exceptions.
• The right to object to or restrict certain processing activities.
• The right to data portability, where applicable.
• The right to withdraw consent at any time, without affecting the lawfulness of processing before withdrawal.

To exercise any of these rights, please contact us using the details in the How to Contact Us section below. We will respond to verified requests within the time frame required by applicable law.

Before responding to a request, we may need to verify your identity to prevent unauthorized access to your information. We will not charge a fee to process a request unless the request is manifestly unfounded, repetitive or excessive, in which case we may charge a reasonable fee or decline to act. If we decline a request, we will explain the reasons for our decision and inform you of any right you may have to complain to a supervisory authority.

11. Privacy for Children

Our website and services are not directed to children under the age of sixteen, and we do not knowingly collect personal information from children. If we learn that we have collected personal information from a child under sixteen without verified parental consent, we will delete that information as quickly as possible.

If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately so we can take appropriate action.

12. International Data Transfers

We are headquartered in China, and the personal information we collect may be stored and processed in China or in other countries where we or our service providers operate. The data protection laws in those countries may differ from the laws in your country of residence.

Where we transfer personal information across borders, we take steps to ensure that appropriate safeguards are in place, including standard contractual clauses or other mechanisms recognized by applicable law, so that your information continues to receive an adequate level of protection.

If you are located in a jurisdiction with specific data protection requirements, such as the European Economic Area or the United Kingdom, and you have concerns about the transfer of your information, please contact us. We will explain the safeguards that apply to your data and, where required, cooperate with you to honor your rights under the law that applies to you.

13. Data Breach Notification

In the event of a security incident that results in the accidental or unlawful destruction, loss, alteration, unauthorized disclosure of, or access to your personal information, we will assess the risk and, where required by applicable law, notify you and the relevant supervisory authority without undue delay.

Our notification will describe the nature of the breach, the categories of information affected, the likely consequences, and the measures we have taken or propose to take to address the incident and mitigate its effects.

14. Do Not Track Signals

Some browsers offer a Do Not Track feature that sends a signal to websites indicating a preference not to be tracked. At this time, there is no widely accepted standard for how websites should respond to such signals, and our website does not currently respond to Do Not Track signals.

You can nonetheless control many tracking technologies directly through your browser settings, as described in the Cookies and Tracking Technologies section above.

15. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, our services or applicable law. When we make material changes, we will update the effective date at the top of this page and, where appropriate, provide a more prominent notice.

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 changes take effect constitutes your acceptance of the revised policy.

If a change materially alters how we use your personal information, we will not apply the new practices retroactively to information collected before the change without first providing notice and, where required, obtaining your consent. We keep a clear record of policy versions so that you can see what has changed and when.
