Privacy Policy

Overview

Lianyungang Chemsize International Trading Co., Ltd. ("Chemsize", "we", "us") respects your privacy. This policy explains what information we collect through this website, how we use it, and how long we keep it.

When you submit the inquiry form on our Contact page, we collect the following information:

• Name / Company name — to address you correctly
• Business email — to reply to your inquiry
• Country / Region — to understand your logistics needs
• Annual volume — to assess capacity requirements
• Mesh / particle size — to quote the right product
• Grade — to match your quality requirement
• Application — to recommend the correct material
• Message — any additional information you provide

We also log your IP address and the time of submission for security and rate-limiting purposes.

How we use your information

• To respond to your inquiry with a quotation, sample, or technical information
• To send you follow-up communications related to your inquiry
• To improve our products and services based on your feedback
• To prevent abuse and spam through rate limiting

We do not use your information for:

• Selling or sharing your data with third-party marketers
• Unsolicited promotional emails (you will only receive responses to your inquiry)

How we store your information

Inquiry emails are sent to our business inbox and stored in our email system. Rate-limiting data (IP address and submission timestamps) is stored in a temporary file on the server and automatically purged after 10 minutes.

We retain inquiry correspondence for up to 24 months to serve ongoing customer relationships. You may request deletion of your data at any time by emailing info [at] chemsize [dot] com.

Cookies & Analytics

We use Google Analytics 4 (GA4) to understand how visitors use our website in aggregate. GA4 sets first-party analytics cookies (such as _ga and _ga_<ID>) that help us measure page views and button clicks (for example, "quote button clicked"). These cookies do not identify you personally, and no name, email, or message content is ever sent to our analytics system.

You can disable cookies in your browser settings, or opt out of Google Analytics entirely using Google's Analytics Opt-out Browser Add-on.

Your rights

• Access: You may request a copy of the information we hold about you.
• Correction: You may ask us to correct inaccurate information.
• Deletion: You may ask us to delete your information, subject to legal retention requirements.
• Opt-out: You may stop receiving communications from us at any time by replying "unsubscribe" to any email.

To exercise any of these rights, contact us at info [at] chemsize [dot] com.

Third-party links

Our website contains links to third-party services (WhatsApp, Google Maps). These services have their own privacy policies. We are not responsible for how third parties handle your data once you leave our website.

Changes to this policy

We may update this Privacy Policy from time to time. The effective date at the top of this page indicates when it was last revised. We will not materially reduce your rights without notice.
