Cangzhou Canal Spring Manufacturing Co., Ltd. ("we", "us") respects your privacy. This policy explains what information we collect on this website (www.czyhth.com), how we use and protect it, and your rights.
1. Information we collect
- Information you submit: the name, phone number, company, email, product of interest and requirements you enter in the quote request form, and any drawings, photos or other files you choose to attach. Name and phone are required; everything else is optional.
- Information recorded with a submission: your IP address and the page you submitted from, used to detect abusive submissions and to see where inquiries come from.
- Server logs: access time, IP address, browser type and pages visited, used to keep the website secure and to troubleshoot problems.
- You do not need an account to use this website. The spring calculators run in your browser; the values you enter are not sent to our servers.
2. How we use it
- To respond to your inquiry with quotations, selection advice and technical solutions based on the requirements and drawings you provide;
- To contact you about your requirements, orders and after-sales service;
- To prevent abusive submissions and keep the website secure.
We do not use your information for any other purpose, and we will not send you unrelated marketing messages without your consent.
3. Storage and security
Your information is stored on servers located in the People's Republic of China. If you are outside China, the information you submit will be transferred to and processed in China. We protect it with HTTPS encryption and access controls; only authorised staff handling your inquiry can view it and any attached files, and attachments are never published on the website.
We keep your information only as long as necessary for the purposes above, then delete or anonymise it, unless the law requires otherwise.
4. Sharing and disclosure
We do not sell, rent or publish your personal information. It may be shared only:
- with your explicit consent;
- internally, when an inquiry alert and any files you attached are sent to the responsible colleagues through workplace messaging tools (such as WeCom, DingTalk or Feishu);
- where required by law or by a lawful request from administrative or judicial authorities.
5. Cookies and analytics
This website uses Baidu Analytics to understand how it is used (such as page views, referring pages and device types). The service uses cookies to collect anonymous usage data, which we use only to improve the website, not for advertising. You can block or clear cookies in your browser settings; this does not affect browsing or submitting an inquiry.
6. Your rights
You may ask us to access, correct or delete the personal information you submitted, or withdraw your consent, using the contact details below. We will respond promptly after verifying your identity. Withdrawing consent does not affect processing carried out before the withdrawal.
7. Children
This website is intended for business customers and is not directed at children under 14. We do not knowingly collect their personal information.
8. Changes to this policy
We may update this policy when our business or applicable laws change. The updated policy will be posted on this page with a new date.
