Cookie Policy

1. What are cookies?

Cookies are small text files that a website stores in your browser to remember your preferences, keep basic functions working and measure traffic. This policy explains which cookies this site uses, why, how long they last and how you can control them.

2. Categories used on this site

This site has no user registration, no online payment and no advertising, and it loads no third-party analytics or social plug-ins. We use only the following essential local-storage items:

Language preference (essential)Stores the interface language you selected (Chinese / English) so the same version is shown on your next visit. Retention: 12 months.

Consent record (essential)Stores your choice on this banner (Accept all / Essential only) and when you made it, so the banner is not shown again. Retention: 12 months.

Analytics cookiesUsed to measure traffic and improve content. No analytics cookies are currently active on this site; if that changes we will update this policy and ask for your consent before they are set.

Map (third party, requires your click)The contact page offers a map view. To avoid transferring data to a third party without your knowledge the map is **not loaded by default**: only after you click “Load map” does your browser request content from the map provider (Google Maps), which may then set its own cookies or record your IP address and usage. That third-party processing is outside the scope of this policy; please see Google's privacy policy. This website itself stores no personal data relating to the map.

Advertising and tracking cookiesThis site uses no advertising, profiling or cross-site tracking cookies and embeds no third-party ad-network scripts.

3. Third-party services and external links

This site loads no third-party analytics, advertising or social plug-ins. **The only possible third-party request is the map on the contact page, and it is made only after you click to load it** (see the “Map” entry in section 2). The site may contain links to external websites (for example regulator websites or customers' own sites); those sites may set their own cookies, which are outside the scope of this policy. Please read their privacy policies.

4. Managing or withdrawing consent

When you first arrive you will see a consent banner offering “Accept all” or “Essential only”. You may withdraw your consent at any time afterwards by clearing your browser cookies and local storage. Withdrawal affects only future processing and does not affect the lawfulness of processing carried out before withdrawal.

5. Browser controls

• All mainstream browsers (Chrome, Edge, Safari, Firefox) let you view, delete and block cookies under “Settings — Privacy and security”.
• Private / incognito mode clears local storage automatically when the session ends.
• Disabling essential cookies may prevent basic functions such as language switching or remembering your consent choice from working.

6. Updates and contact

This policy may be updated to reflect changes in law or in the site's functionality. Any updated version and its effective date will be published on this page. Questions? Contact sales@qzgychem.com.
