Privacy Choices & Requests

1. Manage your current browser choice

You can change optional analytics directly without an account, purchase or identity documents. Open the settings below, reject optional items or customise your choice, and save. Rejection does not affect normal browsing or project enquiries.

Open privacy & Cookie settings

Settings apply to the current browser and website origin. Withdrawal stops further analytics loading, reloads the page and clears Google Analytics cookies this website can control. Data already transmitted needs a separate request. When an enabled GPC signal is recognised, optional analytics remains off. See our Cookie & Tracking Policy.

2. What you can ask for

You can raise a privacy concern with us wherever you are located. Particular statutory rights, conditions and exceptions depend on the law applicable to our business and the processing. You may explain that you want to:

• Find out whether your information is processed, its purposes, sources, recipients and retention, and request access or a copy.
• Correct or complete information, or obtain deletion, restriction or transfer where the relevant conditions are met.
• Withdraw consent, stop marketing, or exercise applicable rights relating to sale, sharing, targeted advertising, sensitive information or certain automated decisions.
• Challenge a refusal or other outcome and make a formal appeal where local law provides that right.

Rejecting analytics and stopping marketing are separate choices. If you only want promotional contact to stop, say “stop marketing” and identify the relevant number or contact details. Necessary communications about project performance, security or legal matters do not automatically stop.

3. Send your request to our contact channels

Responsible company: 河南省青松膜结构工程有限公司. Call +86 185 3947 5789 and identify your request as a personal information rights request. Alternatively, search for 18539475789 in WeChat and send your request after connecting. You may also use an established business communication channel or call to agree a suitable written method. Address: Qingsong membrane structure factory, Miaowang Road, Xingyang, Zhengzhou, Henan, China.

Please explain the name you used to contact us, your original contact details, the relevant page or project, the action you want and a safe way to reply. Your country or region helps determine applicable rights. We will explain if more information is needed. Requests can be written in Chinese or English without a particular legal template.

4. Necessary verification and representatives

To avoid disclosing information to the wrong person, verification will be limited to what is necessary for the request's risk, for example confirmation through your original channel or existing project records. Do not initially send a complete identity document, bank card or unrelated sensitive information. If further evidence is necessary, we will explain why and seek less intrusive alternatives where possible.

An authorised representative may act for you. We may check their authority and your identity as allowed by law. Rejecting analytics in your browser requires no identity verification. Unrelated information should not be made a condition for considering a request.

5. Response times and outcomes

We will handle requests promptly under applicable law. Requests covered by the GDPR generally receive a response within one month of receipt. Where the law permits an extension because of complexity or the number of requests, we will explain the reason within the first month. Access, correction or deletion requests under applicable US state laws generally use a 45-day period; opt-out requests may have shorter deadlines. Other regions follow their own legal time limits. These examples are not a single deadline for every request.

Submitting a request is free. If applicable law permits a reasonable charge for a particular excessive or repetitive request or special delivery method, we will first explain the basis and amount. If we cannot fully fulfil a request, we will explain the lawful reason, what must still be retained and available review or complaint routes. Legal retention, other people's privacy and legitimate rights may limit deletion or disclosure, but do not justify an unexplained refusal.

6. Further review and regulatory complaints

If you believe a response is inadequate, use the same channels to seek clarification or review. You can also seek relief from a competent data protection or consumer protection authority or court without first giving up any rights. In the EU and UK, you can contact the relevant data protection authority; in the US, Canada, Brazil and elsewhere, contact the competent local body. See the regional section of our Privacy Policy.
