Privacy & cookies

How we handle the information you send through this website.

Who we are

This website is operated by Jiangsu Zhongjie Environmental Technology Co., Ltd., registered in Nanjing, Jiangsu, China. For any question about this notice, write to leo@gdzjmembrane.com.

What we collect

The enquiry form collects the name, company, work email, country or region, feed or application, and the description you choose to provide. Visitors who do not submit the form are not asked for these details.

Advert attribution

If you arrive from an advert, the enquiry form also carries the click identifier (gclid or msclkid), campaign tags and the first page you opened, so we can match an enquiry to its source. With your consent these values are kept in your browser for 30 days; without consent they are used on the current page only.

Why we collect it

The information is used to answer your enquiry, suggest a membrane type and prepare a quotation. It is not sold and is not used for unrelated marketing.

Cookies and measurement

With your consent we may load Google Analytics and Google Ads measurement to count visits and attribute enquiries to an advert. Until you accept, advertising and analytics storage remain denied under Consent Mode v2. Clearing this site data lets you choose again.

Third parties

Google Ireland Limited and Google LLC receive measurement data only after consent. Enquiry messages are delivered to our own mailbox; they are not passed to other marketing platforms.

Retention

Enquiry correspondence is kept for as long as the business discussion requires. Measurement data follows the retention setting of the analytics account.

Your rights

You can ask for a copy, a correction or deletion of the personal information you submitted, and you can withdraw cookie consent. Write to leo@gdzjmembrane.com and we will respond.
