Privacy notice

Last updated: 9 November 2026

This notice explains what happens to the information you send us through dingxiusolar.com. It is written to be read, not to hide behind. If anything here is unclear, write to nereosong@dingxiusolar.com and we will answer in plain language.

1. Who is responsible for your data

HEBEI DINGXIU INTERNATIONAL TRADE CO., LTD. (trading as DINGXIU SOLAR), a company registered in China. Our registered address is East side of Kaiyuan Road, 200 m south of Shuangta, Baita Town, Shahe City, Xingtai, Hebei, China. For any question about this notice or your data, contact nereosong@dingxiusolar.com or +86 158 3365 5952.

2. What we collect

Only what you type into the enquiry form, and only when you choose to send it:

Data	Why we ask	Required?
Name	So we know who we are replying to	Yes
Email address	To send drawings, calculations and the quotation	Only if you use the email button
Company	To judge whether the enquiry is trade or end user	No
Country / site location	Wind zone, duty rate and freight calculation	Yes
Your role, project size, module model, roof type, quantity, delivery window, notes	To produce a usable layout and a real price instead of a generic one	No

The calculator runs entirely in your browser. The values you enter there are not transmitted anywhere unless you press one of the send buttons on the contact page. There is no account, no login and no tracking of individual visitors beyond the aggregate statistics described in section 4.

3. What we do with it

• Reply to your enquiry, with a layout drawing, ballast calculation, container loading and a quotation.
• Keep a record of the correspondence so we can answer follow-up questions and honour prices we have quoted.
• Nothing else. We do not add you to a mailing list, we do not send marketing email, and we do not sell, rent or trade your details to anyone.

Where data protection law requires a legal basis, we rely on your consent (which you give by ticking the box before sending) and on our legitimate interest in responding to a business enquiry you initiated. You can withdraw consent at any time by writing to us; withdrawal does not affect anything done before it.

4. Who else processes your data

We use a small number of service providers. They process data on our instructions only:

Provider	What it does	Where
Netlify	Hosts this website and keeps standard server logs (IP address, browser, requested page) for security and abuse prevention	United States / global CDN
Web3Forms	Receives the enquiry form and forwards it to our mailbox	United States
Zoho Mail	Hosts our business email, where enquiries are stored	India / United States
Google Analytics 4	Aggregate visit statistics (pages viewed, country, device), IP addresses anonymised. Loaded only if enabled.	United States
Microsoft Clarity	Aggregate interaction statistics such as scroll depth and clicks. Loaded only if enabled.	United States
WhatsApp (Meta)	Only if you press a WhatsApp button. Your message is sent from your own account under WhatsApp's own terms.	Global

Because some of these providers are outside the country where you live, your data may be transferred internationally. We choose providers that publish standard contractual clauses for such transfers.

5. Cookies

This website sets no cookies of its own. There is no cookie banner because there is nothing to consent to by default: the site is a set of static files, and the calculator needs no storage. If analytics is enabled at some point, those providers may set their own cookies; in that case this section will be updated and a consent control added first.

6. How long we keep it

• Enquiries that do not lead to an order: deleted after 24 months.
• Enquiries that become orders: kept as long as required by Chinese tax and export record-keeping rules.
• Server logs at the hosting provider: typically a few weeks, under their own retention policy.

7. Your rights

You can ask us, at any time and free of charge, to:

• tell you what data we hold about you, and give you a copy;
• correct anything that is wrong;
• delete it, if we have no legal obligation to keep it;
• stop using it for a particular purpose, or object to our processing;
• receive it in a machine-readable format, where the law gives you that right.

Write to nereosong@dingxiusolar.com with the subject line "Data request". We answer within 30 days. If you are in the EU or UK you also have the right to complain to your national data protection authority.

8. Security

This website is served over HTTPS only, with HTTP requests redirected. It holds no database and no user accounts, so there is no login to steal. Enquiries travel over TLS to our form processor and are stored in our business mailbox, protected by two-factor authentication. Access is limited to the people who answer enquiries.

9. Children

This is a business-to-business site for solar mounting systems. It is not directed at children and we do not knowingly collect data from anyone under 16.

10. Changes

If this notice changes, the date at the top changes with it. Material changes affecting how we use data you have already sent will be communicated to you directly by email where we still hold your address.
