1. What we collect
Only what you type into the enquiry form: your name, email address, phone number, company, country and your message. We do not run advertising trackers, analytics scripts or third-party pixels on this website, and we do not create accounts or profiles for visitors.
2. Why we collect it
To reply to your enquiry and, if you ask for one, prepare a quotation. Your details are used for that purpose only. We do not add enquirers to a mailing list, and we do not sell or share your details with third parties for marketing.
3. Cookies

4. Where your data goes and how long it stays
Enquiry messages are delivered to our sales mailbox at yinhongtao@yunkukeji.com and handled by our sales staff. We keep enquiry correspondence for as long as needed to deal with your request and any resulting business, then delete it. We do not transfer your data to any other organisation.
5. Your rights
You can ask us at any time for a copy of the details you sent us, ask us to correct them, or ask us to delete them — just email yinhongtao@yunkukeji.com. If you are in the EU or the UK, you also have the right to lodge a complaint with your local data protection authority.
