Privacy & Cookie Policy

Last updated: 1 August 2026

Who we are

This website, dhesenergy.com, is operated by Liaoning Dahua Energy Technology Co., Ltd. ("DHES", "we", "us").

Registered office: A408, Building F8, Shenyang International Software Park, Liaoning Province, China.
Factory and production facility: Yingfeng Environment Shunde Industrial Park, No. 8 Huishang Road, Leiqiao Subdistrict, Shunde District, Foshan City, Guangdong Province, China.

For any question about this policy or about your personal data, contact us at info@zgenergytech.com.

What we collect

Information you give us

We collect personal data only when you choose to send it to us through one of the two forms on this site.

Quotation request form (on the Contact page): your name, company name, email address, telephone or WhatsApp number, the product you are interested in, and your message.

Enquiry form (in the site footer): your name, country, city, telephone number, email address, your message, and whether you have asked to receive updates from us.

Both forms require a name, an email address and a message. The remaining fields are optional but help us answer you accurately.

Information collected automatically

Our hosting provider records standard server logs when a page is requested, including the IP address, browser type, the page requested and the time of the request. These logs are used to deliver the site, keep it secure and diagnose faults.

What we do not collect

This site does not use any web analytics or visitor tracking service. There is no Google Analytics, no advertising pixel, no heatmap or session recording tool, and no behavioural profiling of any kind. We do not build a profile of you, we do not track you across other websites, and we do not sell or share personal data for advertising purposes.

Why we use it, and on what legal basis

We use the information you submit to respond to your enquiry, prepare a quotation, and continue commercial correspondence with you. Where the General Data Protection Regulation (GDPR) applies, our legal basis is the steps taken at your request prior to entering into a contract, and our legitimate interest in responding to business enquiries.

If you tick the box to receive updates, we use your email address to send occasional company and product news. The legal basis is your consent, and you may withdraw it at any time by replying to any message or writing to us.

Server logs are processed on the basis of our legitimate interest in operating a secure and functioning website.

Cookies and similar technologies

Strictly necessary

When you choose to accept or reject cookies, your choice is stored in your browser so that the notice is not shown again on every page. This storage is required for the site to respect your preference and cannot be switched off.

Third-party cookies

Google Maps. Our Contact page embeds two Google Maps frames showing our office and factory locations. When that page loads, Google may set its own cookies and receive your IP address. This happens under Google's own privacy terms, not ours. Every other page on this site loads without any third-party cookie.

Services that receive your IP address without setting cookies

Google Fonts. Typefaces used across the site are loaded from Google's servers, which means your IP address is transmitted to Google when a page loads.

jsDelivr. The international telephone selector in our footer form loads from the jsDelivr content delivery network, which likewise receives your IP address.

Neither service sets cookies or identifies you personally.

Managing cookies

You can accept or reject non-essential cookies using the notice shown on your first visit. You can also delete or block cookies through your browser settings at any time. Blocking third-party cookies may prevent the maps on our Contact page from displaying; nothing else on the site is affected.

Who else processes your data

We keep the number of third parties deliberately small.

Netlify. This website is hosted by Netlify, and the two forms are delivered through Netlify Forms. Submissions are stored on Netlify's infrastructure and forwarded to our team by email. Netlify acts as our processor and operates servers in the United States and other locations.

We do not use email marketing platforms, customer data platforms, advertising networks or data brokers. Your enquiry is read by our sales and technical staff, and by nobody else.

International transfers

DHES is established in China. If you contact us from the European Economic Area, the United Kingdom or another region with data transfer restrictions, the information you submit will be transferred to and processed in China, and stored on Netlify infrastructure which may be located in the United States.

These countries are not covered by an adequacy decision of the European Commission. We rely on the transfer being necessary for the performance of a contract with you, or for steps taken at your request prior to entering into a contract. If you would prefer not to transfer your data on this basis, please contact us by telephone instead.

How long we keep it

We retain enquiry and quotation correspondence for as long as needed to handle your request and for the duration of any resulting commercial relationship, and thereafter for a period of 24 months in case you contact us again about the same project. Where a contract is concluded, records are kept for the longer period required by applicable accounting and tax law.

If you asked to receive updates, we keep your email address until you withdraw consent.

Server logs are retained for a short period by our hosting provider and are not used to identify individuals.

Your rights

Subject to applicable law, you may ask us to:

• confirm whether we hold personal data about you, and give you a copy of it
• correct data that is inaccurate or incomplete
• delete data we no longer have a valid reason to keep
• restrict how we use your data, or object to our use of it
• receive your data in a portable format, or have it sent to another provider
• withdraw your consent to receiving updates, at any time

Write to info@zgenergytech.com and we will respond within one month. There is no charge. If you are in the EEA or the UK and you believe we have not handled your data properly, you also have the right to complain to your national data protection authority.

Security

This site is served exclusively over an encrypted HTTPS connection. Form submissions are transmitted over TLS and stored in an access-controlled environment. Access to enquiry data is limited to the DHES staff who need it to reply to you.

No transmission over the internet can be guaranteed to be completely secure. Please do not send sensitive information — such as identity documents, bank details or payment card numbers — through the forms on this site. We will never ask you for them by email.

Children

This is a business-to-business website intended for professional users. It is not directed at children and we do not knowingly collect data from anyone under 16.

Changes to this policy

If we change the way we handle personal data, we will update this page and revise the date shown at the top. Where the change is significant, we will make it clear on the site.
