Privacy Policy

1. Who we are

This website is operated by Guangzhou HydroWorks Environmental Technology Co., Ltd., DrinkingWaterTreatment Office, Room 312L, Huilange BLDG, No. 273, Huangpu Blvd W, Tianhe District, Guangzhou 510620, Guangdong, China. For privacy questions, email sale@commercialwaterfilterfactory.com.

2. What we collect

We collect only the information you choose to send: name, company, email, phone, country, water source, water quality values, daily demand, application and your message. The inquiry form is processed by Web3Forms, a third-party form service that forwards the submission to our sales email; Web3Forms stores the submission for a limited period under its own privacy policy.

We also use Google Analytics 4 and Microsoft Clarity, loaded only after you accept analytics cookies, to understand page usage and improve the site. These tools may collect device, browser, approximate location and interaction data. Our web server may record standard technical logs (IP address, browser type, requested page, time) for security and troubleshooting. We do not use advertising trackers or sell data.

3. How we use it

We use your information to answer your inquiry, prepare a quotation, arrange shipping and provide after-sales support. We may contact you by email or phone about the specific project you asked about. We do not send unrelated marketing without consent.

4. Sharing and retention

We share information only with parties needed to fulfil your order or operate the site: Web3Forms for form delivery, Google and Microsoft for analytics (only with your consent), and freight forwarders or component suppliers where required. We do not sell data. We keep inquiry records for as long as needed to support the project and meet accounting obligations, then delete or anonymise them.

5. Your rights

You may request access to, correction of, or deletion of the personal data we hold about you by emailing sale@commercialwaterfilterfactory.com. We respond within 30 days. If your local law provides additional rights, tell us and we will apply them.

6. Security

Access to inquiry records is limited to staff who need it. Data is stored on access-controlled systems. No transmission over the internet is completely secure; please avoid sending sensitive personal data beyond what the inquiry requires.

7. Changes

We may update this policy when our practices change. The revision date at the top of the page shows the current version.
