1. Introduction
Shaanxi Yixuanyuxin Trade Co., Ltd., referred to in this document as the Company, respects the privacy of every person who visits this website, requests a survey, commissions an integration or otherwise interacts with our business. This Privacy Policy explains, in plain English, what personal data we collect, why we collect it, how we store it, who may see it, and what choices you have. The developer YixuanRain built and maintains this website and has ensured that the data practices described here match the way the site actually behaves.
We are an engineering firm working in computer integrated systems design for industrial plants. Our customers are businesses, and our website is primarily a professional tool. Even so, individuals visit the site, send messages, download documents and correspond with our engineers, and those interactions produce personal data that deserves careful handling. This policy describes that handling without unnecessary legal jargon, while still covering the obligations that apply to us.
By using this website and by contacting the Company through the channels provided here, you acknowledge that you have read this Privacy Policy and that you understand the practices it describes. If you do not agree with any part of this policy, please do not use the website or submit personal data through it.
2. Scope of This Policy
This Privacy Policy applies to personal data collected through the website located at yixuanrain.lat, to personal data collected through the contact form, email correspondence, telephone calls and site visits, and to personal data processed in connection with the engineering, monitoring, telemetry and support services that the Company provides.
This policy does not apply to third party websites that may be linked from our pages, to customer owned control systems that we integrate but do not operate, or to employee records of the Company, which are governed by separate internal policies. Where a customer engages us to process data on their behalf, our handling of that data is additionally governed by the written agreement between us and the customer.
If you are an employee or representative of a customer, a supplier or a partner, the personal data we hold about you is limited to the details needed to manage that relationship, and this policy explains how that data is treated.
3. Data We Collect
The categories of personal data we may collect include the following. We collect only what is reasonably needed for the purpose at hand, and we avoid collecting sensitive categories of data unless a specific project genuinely requires it.
- Identity data such as your name, job title, employer and role in a project.
- Contact data such as email address, telephone number and postal address.
- Correspondence data such as the content of messages you send through the contact form or by email.
- Project data such as site details, equipment lists and technical requirements you share with us.
- Technical data such as browser type, device type, approximate region and pages visited.
- Usage data such as the times and frequency of your visits and the actions you take on the site.
- Contractual data such as quotations, purchase orders and service records.
We do not intentionally collect information about your health, your political opinions, your religious beliefs, your trade union membership, your genetic characteristics or your precise location. If you choose to volunteer such information in a message, we will treat it with care but we do not request it and we do not build profiles from it.
4. How We Collect Data
We collect personal data in several ways. Most directly, we collect data when you complete the contact form, when you send us an email, when you call us, when you exchange messages with our engineers, or when you hand us a business card at a trade event or on a site visit. In each of those cases you are providing the data deliberately, and you control how much you share.
We also collect data automatically as you browse the website. This includes technical data that your browser sends to our server, such as the type of device you are using and the pages you request. This automatic collection is standard for modern websites and helps us keep the site working correctly.
Finally, we may receive data about you from a colleague at your company, from a shared project record, or from a public professional directory, where that information is relevant to a legitimate business relationship. When we receive data from another source, we handle it in the same careful way that we handle data you give us directly.
5. Why We Use Your Data
We use personal data for clear and limited purposes. We use it to respond to enquiries and to provide the information you request. We use it to prepare quotations, plan surveys and deliver the engineering, monitoring and support services that a customer has asked for. We use it to keep records of projects and to maintain the as-built documentation that our clients rely on long after handover.
We use contact data to send service notices, maintenance reminders and, where you have agreed, occasional updates about our capabilities. We use technical data to keep the website secure, to diagnose faults and to understand which pages are useful so that we can improve them. We use accounting and contract data to meet our own legal and financial obligations.
We do not use personal data for automated decision making that produces legal or similarly significant effects, and we do not use personal data to train external artificial intelligence systems. If that ever changes, we will update this policy first and provide a clear way to object.
6. Legal Bases for Processing
Where the law requires us to identify a legal basis for processing, we rely on the following grounds. First, we process data because it is necessary to perform a contract with you or to take steps at your request before entering a contract, for example when we prepare a quotation or deliver a service. Second, we process data because it is necessary for our legitimate interests in running a professional engineering business, provided those interests are not overridden by your rights.
Third, we process data where you have given consent, for example when you agree to receive marketing communications. You may withdraw that consent at any time, and withdrawal does not affect the lawfulness of processing carried out before the withdrawal. Fourth, we process data where it is necessary to comply with a legal obligation, such as tax and accounting requirements.
Where we rely on legitimate interests, we apply a balancing test and we keep the scope of processing proportionate. We retain records of those assessments so that our decisions can be reviewed.
7. Technical and Network Data
Like most websites, ours receives technical data from your browser each time you request a page. This includes your Internet Protocol address, the date and time of the request, the page you requested, the referring page if any, and information about your browser and operating system. This data is used to deliver the page to you, to protect the site from abuse and to maintain reliable operation.
We treat technical data as personal data where it can reasonably be linked to an individual. We store it for a limited period and we restrict access to the staff who need it for security and operations. We do not sell technical data, and we do not combine it with other data to build advertising profiles.
Server logs and security records are essential to keeping the website available. If you attempt to breach the site, we may retain the relevant records for longer in order to investigate the incident and to meet any legal obligations that follow from it.
9. Engineering and Project Data
When the Company delivers an integration, we necessarily handle technical and operational information about a client site. This may include equipment lists, network details, control narratives, sensor readings and historical trends. Some of this information may relate to identifiable individuals, such as the name of a maintenance engineer associated with an alarm, and we treat that portion as personal data.
Project data is stored in controlled repositories with access limited to the engineers assigned to the work. We retain project data for the period needed to support the plant and to meet our contractual obligations, after which it is deleted or anonymised. Where we process data on behalf of a customer, that customer is the controller of the data and we act on documented instructions.
Recovery of energy, scheduling of maintenance and monitoring of air quality all rely on plant data rather than on personal data wherever possible. We design our systems to minimise the personal content of the operational records we keep.
11. Service Providers and Processors
We engage a small number of service providers to run the website and our business systems. These may include a website host, an email service, a domain registrar and providers of accounting or document storage tools. Each provider is selected with care and is required to protect personal data under a written agreement.
Processors act only on our instructions and may not use the data for their own purposes. We review our processors periodically and we require them to notify us of any incident that affects personal data. Where a processor is located outside the region in which the data was collected, we put appropriate safeguards in place before any transfer occurs.
If you need more detail about the categories of processor we use, you may contact us using the details in this policy and we will explain the safeguards that apply to your data.
12. Data Retention
We keep personal data only for as long as necessary for the purposes described in this policy or as required by law. Enquiry data is kept for as long as needed to deal with the enquiry and for a reasonable period afterwards in case the matter is reopened. Contract and accounting records are kept for the period required by applicable tax and commercial law.
Project records are retained for the life of the plant they support and for a reasonable period afterwards, because maintenance and troubleshooting depend on historical documentation. When that period ends, records are securely deleted or anonymised so that they no longer identify any person.
Where you ask us to delete data and no legal or contractual reason requires us to keep it, we will delete it promptly and confirm that we have done so.
13. Security Measures
The Company takes the security of personal data seriously. We use technical and organisational measures that are appropriate to the risks, including encryption of data in transit where the technology supports it, access controls on our systems, and the principle of least privilege for staff accounts. Staff who handle personal data are aware of their responsibilities.
Our engineering background informs our security posture. We routinely design controls for industrial environments where reliability and safety matter, and we apply the same discipline to our own information systems. Access to project and personal data is logged where the platform allows, and off boarding of staff and contractors includes prompt revocation of access.
No system can be guaranteed to be completely secure. If we become aware of a breach that is likely to affect your rights and freedoms, we will notify you and the relevant authorities as required by law, and we will take steps to contain the incident and prevent it from recurring.
14. International Transfers
The Company is based in Xian, China, and our services may involve clients and suppliers in other countries. Personal data may therefore be transferred to, stored in, or processed in a country other than the one in which it was collected. Where such a transfer occurs, we take steps to ensure that the data continues to receive an appropriate level of protection.
Those steps may include using standard contractual clauses approved for the purpose, relying on an adequacy decision where one exists, or obtaining your consent where the law permits that approach. We review the jurisdictions to which data may be transferred and we update our safeguards as the legal landscape changes.
If you would like more information about the specific safeguard that applies to a transfer of your data, please contact us using the details at the end of this policy.
15. Your Privacy Rights
Depending on where you live, you may have a number of rights in relation to your personal data. These may include the right to be informed about how your data is used, the right of access to the data we hold about you, the right to have inaccurate data corrected, and the right to have data erased where there is no continuing lawful reason for us to keep it.
You may also have the right to restrict processing, to object to processing based on legitimate interests, to receive a portable copy of data you provided to us, and to withdraw consent where processing is based on consent. You have the right not to be subject to a decision based solely on automated processing that produces legal or similarly significant effects.
To exercise any of these rights, contact us using the details at the end of this policy. We will respond within the period required by law, and we may ask for information to confirm your identity so that we do not disclose data to the wrong person. You also have the right to complain to a supervisory authority in your country, though we would appreciate the chance to resolve your concern first.
16. Privacy for Children
The website and the services of the Company are intended for businesses and professional users. They are not directed at children, and we do not knowingly collect personal data from children. If you believe that a child has provided personal data to us, please contact us and we will delete that data promptly.
Where a school, a training provider or another organisation works with us and involves younger people, that organisation is responsible for obtaining any consents required and for ensuring that the data shared with us is appropriate and minimal.
17. Marketing and Communications
We may send service updates, maintenance reminders and occasional information about our capabilities where we have a legitimate interest or your consent to do so. Every marketing message includes a way to opt out, and we honour opt out requests promptly. Opting out of marketing does not prevent us from sending essential service messages about a project you have engaged us to deliver.
We keep marketing lists separate from operational records and we limit the frequency of our messages so that they remain useful rather than intrusive. We do not share your contact details with third parties for their own marketing purposes.
18. Third Party Websites
Our website may link to websites operated by other organisations. Those websites have their own privacy policies and practices, and the Company is not responsible for them. We encourage you to read the privacy policy of any website you visit, especially before providing personal data.
Links from our site do not imply endorsement of the linked organisation, and the presence of a third party link does not mean that we share data with that party. Any interaction you have with a linked website is between you and that website.
19. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, in the services we offer, or in the law. When we make a material change, we will update the effective date at the top of this page and, where appropriate, provide a more prominent notice on the website.
We encourage you to review this page periodically so that you remain aware of how we protect your data. Continued use of the website after an update takes effect indicates that you accept the revised policy.
