Privacy Policy
Last updated: 12 November 2026
Shanghai Chiyan Abrasives ("we", "us", "our") operates
https://www.cynail.com (the "Site"). This policy explains what personal information we collect, how we use it, with whom we share it, and the choices you have. It applies to the Site, to enquiries you send us by email, phone or messaging app, and to forms you submit through our advertising.
1. Information we collect
Information you give us. When you request a quotation or a sample, ask about OEM/ODM terms, place an order, subscribe to updates, or submit a form in one of our ads, you may give us: your name, company name, job title, email address, phone number, country or region, shipping address, product specifications and quantities, and the content of your message.
Information collected automatically. When you visit the Site we may record your IP address, device type, browser type, referring URL, pages viewed, and the date and time of your visit. We derive approximate location (city or region level) from your IP address.
Cookies and similar technologies. See Section 5.
We do not knowingly collect personal information from anyone under 16. If you believe a minor has provided information to us, contact us and we will delete it.
2. Forms submitted inside our advertisements
If you complete a lead form shown in one of our Google Ads, Google passes to us the details you entered — such as your name, email address, phone number, company name and your answers to the questions in that form. Google does not share your account password or the content of your Google account with us. Our handling of that information is described in this policy. Google's own handling of your data is governed by Google's privacy policy.
3. How we use information
We use personal information to:
We do not use your information for automated decision-making that produces legal or similarly significant effects.
4. Legal bases (EEA and UK visitors)
Where the GDPR or UK GDPR applies, we rely on: performance of a contract (handling your order or quotation request); legitimate interests (responding to business enquiries, improving our products, keeping the Site secure, and measuring our advertising); consent (marketing emails and non-essential cookies, which you may withdraw at any time); and legal obligation (record keeping).
5. Cookies, analytics and advertising
We use first-party and third-party cookies and similar technologies, including Google Analytics 4 and Google Ads conversion tracking (Google tag ID AW-18541606128), to understand how the Site is used and to measure and improve advertising performance. These technologies may collect your IP address, device and browser information, pages visited, and actions taken on the Site. If you are signed in to a Google account, Google may associate this data with your account under its own policies.
You can:
6. Sharing information
We do not sell personal information, and we do not share it for cross-context behavioural advertising in exchange for money. We share it only with:
service providers that host the Site, deliver email, provide analytics and advertising (including Google), process payments, and arrange shipping — each bound by contract to use the data only for the service they provide to us;
authorities or other parties where required by law, or where necessary to protect our rights, property or safety, or those of others;
Some of these providers process data outside your country. Where required, we put appropriate safeguards in place, such as standard contractual clauses.
7. How long we keep information
When information is no longer needed, we delete or anonymise it.
8. Your rights
Depending on where you live, you may have the right to: access the personal information we hold about you; have inaccurate information corrected; have your information deleted; restrict or object to certain processing; receive your information in a portable format; and withdraw consent you previously gave. California residents may request to know what we collect, to delete or correct it, and to opt out of "sale" or "sharing" — we do not sell personal information.
To exercise any of these rights, email us at the address in Section 12. We may ask for information to verify your identity before acting. You also have the right to complain to your local data protection authority.
9. Security
We use technical and organisational measures — including encrypted connections, access controls and staff confidentiality obligations — to protect personal information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
10. Links to other sites
The Site may link to third-party sites, including our social media and marketplace pages. We are not responsible for their privacy practices; please review their policies.
11. Changes to this policy
We may update this policy to reflect changes in our practices or the law. The "Last updated" date at the top shows when it was last revised. Material changes will be announced on this page.
