Cookie & Tracking Policy

1. Analytics is on by default, and you can reject it

This website is operated by 河南省青松膜结构工程有限公司. Cookies are small files stored by your browser; local storage is another way to save settings on your device. Visitor analytics loads by default to measure website use. You can reject analytics from the footer settings. Rejecting analytics does not prevent you from viewing products, projects or articles, or contacting us.

You can reopen settings at any time using the footer or the button below to reject analytics or customise your choice. Browsing, scrolling or closing the browser does not change the current setting or count as consent for other purposes.

2. Storage used by this website

• Privacy choice record — necessary: qs_privacy_choice_v1 is saved by this website in your browser's local storage. It records your selection, time and policy version. The choice is valid for 180 days. It respects your decision and is not used for analytics or advertising.
• Necessary sessions and security: the server may use session or security cookies where a particular function needs them. Names and lifetimes depend on the actual function. They support the requested service, security or session continuity; they are not necessarily created on every visit.
• Google Analytics — visitor analytics: Google Analytics loads by default on this website and can be rejected in privacy settings. Common cookies are _ga and _ga_*, used to distinguish browser visits and maintain session state. Google's default lifetime is generally two years, can be shortened or adjusted by configuration, and may refresh on visits. The actual lifetime depends on browser records and the applicable configuration.
• Advertising tracking: advertising purposes are disabled by default. Adding an advertising tool or new tracking purpose requires an updated notice and a further choice where applicable.

3. Analytics information and third parties

Analytics tools may receive page visits, referral pages, device and browser information and online identifiers to help us understand useful content. Online identifiers do not make information fully anonymous. Network connections also involve technical information such as IP addresses, and processing may take place abroad. If you reject analytics, this website stops loading the analytics code controlled by your choice.

See Google's Privacy Policy for its handling of data and Google's official Cookie documentation for configuration details. If you follow links to WeChat, maps or other external services, their own storage and privacy rules apply. Your website choice does not replace settings within those services.

4. Withdrawal, removal and browser signals

If you reject analytics in settings and save, this website stops further analytics loading, reloads the page and attempts to remove _ga cookies it can control. Removing local cookies does not automatically erase data already sent to a provider. For further action, use Privacy Choices & Requests.

When this website detects a recognisable Global Privacy Control (GPC) signal from your browser, it keeps analytics off, including where you previously consented. The signal applies to browser visits in which it is recognised; it does not synchronise choices across other websites or devices.

You can also inspect, delete or block storage in your browser. Choices are stored for the current browser and website origin. Changing devices, browsers or domains, clearing storage or reaching expiry returns analytics to its default-on state. If your browser cannot save the setting, rejection may apply only to the current page; analytics returns to its default-on state after you leave or reload. See our Privacy Policy for further information and contact details.
