Privacy Policy

Who we are

This website is operated by Henan Huanzhou Information Technology Co., Ltd. ("we"). We are the controller of the personal data collected through this website.

What we collect

Information you submit through the inquiry form:

• name (required) and business email (required) — so we can reply to you;
• company, country/region, product and the SKU you selected, quantity, preferred contact method, WhatsApp number (optional) — to prepare a quotation;
• your requirements text (required);
• optional attachments: up to 3 files (PDF/JPG/PNG), max 25 MB each.

Technical information created when you submit

To keep the form usable and free of abuse we also record: a salted hash of your IP address (we never store your IP address in plain text), your browser's User-Agent, the page you submitted from, your interface language, and the time between opening and submitting the form.

Cookies and local storage

We do not use advertising, analytics or third-party tracking cookies. Your language preference (en/ru) is stored in your browser's local storage only when you explicitly switch language.

What we do not collect

We do not ask for or need identity documents, payment card data, biometric, health or precise location data. Please do not include such information in your message or attachments.

Why we process your data

We do not use your data for advertising, for bulk marketing, for profiling or automated decision-making, and we do not sell or rent it. Inquiries are not sent to third-party AI services.

• to answer your inquiry and prepare a quotation — necessary to take steps at your request (GDPR Art. 6(1)(b));
• to keep the website secure and free from abuse, such as rate limiting and spam filtering (our legitimate interest — Art. 6(1)(f));
• to comply with legal obligations, such as records required by tax or dispute rules (Art. 6(1)(c)).

Who can access it

Only our staff, plus two service providers acting on our behalf: our cloud hosting provider, whose servers are located in the United States and where the website and inquiry data (including attachments) are stored; and Google (Gmail), which delivers the inquiry notification email to us — the attachment files themselves are not sent by email. We disclose data otherwise only where the law requires it.

International transfers

Data is stored on servers in the United States. If you submit an inquiry from the EU/EEA, this transfer is necessary in order to handle the request you made (GDPR Art. 49(1)(b)). You are welcome to ask us to communicate by email instead.

How long we keep it

• inquiry records and attachments: 24 months after our last contact, then deleted;
• daily backups: the 7 most recent copies are kept, so deleted data may remain in backups for up to about 7 days;
• server access logs: kept short-term by the hosting provider for security troubleshooting.

Your rights

Under applicable law (for example GDPR or CCPA) you may ask us to give you access to your data, correct it, delete it, restrict or object to its processing, or provide it in a portable form, and you may withdraw your consent at any time. Write to the address below with the subject "Privacy request"; we normally respond within 30 days. You may also lodge a complaint with your local data protection authority.

How we protect your data

• the site is served over HTTPS/TLS;
• attachments are stored in a private directory that is not publicly accessible (anonymous requests return 404 and no download route exists);
• IP addresses are stored only as salted hashes;
• the inquiry endpoint applies rate limiting and spam filtering;
• access to server data is limited to authorised staff.

Children

This is a business website for sourcing and technical staff. It is not intended for children under 16, and we do not knowingly collect their data. Contact us if you believe a child's data was submitted and we will delete it.

Changes to this policy

We may update this policy and will change the effective date accordingly. If a change is material — for example, if we ever add analytics — we will highlight it on the site.
