Who we are
This Privacy Policy explains how CRESTVANE INDUSTRIAL LIMITED ("CrestVane", "we", "us" or "our") handles personal data in connection with crestvaneindustrial.com, our industrial-product information service and business communications.
Registered office: Room 316, 3/F, 143 Wai Yip Street, Kwun Tong, Hong Kong. Company Registration No.: 81185718. For privacy requests, contact sales@crestvaneindustrial.com.
Information we handle
We process the information you choose to send to us by business email or through an external messaging service, such as your name, business contact details, company, country or region, product models, quantities, technical requirements, purchasing information and files you attach. Please do not send passwords, payment-card data, identity documents or information that is unrelated to your request.
When you visit the Website, our systems may process limited technical information needed to operate and secure it, such as IP address, browser or device information, request time, page path, language selection and error or security logs.
Why we use information
We use information to respond to product and quotation requests, verify models and requirements, communicate about a potential or confirmed transaction, provide support, protect the Website, prevent misuse, maintain records, and comply with applicable legal obligations. Sending us an inquiry does not subscribe you to marketing messages. We use direct-marketing contact details only where permitted and you may ask us to stop at any time.
Cookies, local storage and optional measurement
Necessary browser storage supports security, language selection and your privacy choice. The Website stores a consent preference in local storage for up to 180 days. When you choose WhatsApp Sales, the assigned chat destination is stored in your browser for 30 days so the same browser can reuse it; the server routing state does not store your contact details.
Analytics and advertising measurement are optional. They remain off until you make the corresponding choice in Cookie Settings, and you can change that choice at any time. The Website currently has no valid production Google Analytics or Google Tag Manager ID configured; if an optional provider is added, we will update this Policy and the relevant consent controls before using it.
Sharing and international processing
We may share information only as needed with personnel who handle your request and with service providers supporting hosting, email delivery, IT, security, professional advice, payment, delivery or legal compliance. We may also share information when required by law or to establish, exercise or defend legal claims. International suppliers and service providers may process information outside your country; where this occurs, we will use safeguards required by applicable law.
Retention and security
We retain information only for as long as reasonably necessary for the purpose collected, our business records, legal obligations, dispute handling and security, then delete or anonymise it where appropriate. We use reasonable technical and organisational measures designed to protect information, but no online transmission or storage method is completely secure.
Your choices and rights
Subject to applicable law, you may request access to or correction of personal data we hold about you, object to certain uses, withdraw a consent-based choice, or ask about our handling of your data. Email sales@crestvaneindustrial.com with enough information for us to identify your request. We may ask for proportionate verification before responding.
External services, children and updates
External websites and messaging services, including WhatsApp, have their own privacy practices. This Policy does not govern their independent processing. The Website is intended for business and professional users and is not directed to children. We may update this Policy when our practices or legal requirements change; the effective date above shows the current version.
