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