Privacy Policy
Last updated: September 5, 2026
This notice describes the current website inquiry flow. Project-specific legal and data-handling terms may be identified in the applicable quotation or contract.
Who handles your inquiry
CS is the specialist website route for custom magnet inquiries. Shenzhen Changsheng Sign Co., Ltd. is the manufacturing entity and factory contact. CHANGSHENG HARDWARE SIGNS MING-EDITION (HK) LIMITED handles international contracting, invoicing and payment. These roles are distinct, and no ownership relationship between the entities is inferred from this notice.
The responsible entity for a specific transaction is identified in its quotation or contract. This notice does not claim that either entity is a parent, controller or joint controller unless that is confirmed in writing for a given transaction.

Data collected
When you submit the Request a Quote form, the information you enter is recorded. This may include your name, company, work email, country, buyer type, target market, intended use or sales channel, product and specification answers (such as product route, quantity, dimensions, construction, decoration, finish, backing and packaging), artwork status, dates, delivery country or postcode, compliance and audit needs, and any additional notes.
A request reference and the underlying system record are created when you submit. If you email us directly, email metadata and the content of your message may also be received and retained.
Limited technical logs, such as IP address, browser or device information, may be generated by hosting and security providers that help deliver and protect the site.
The web form does not upload files. Agree a secure transfer route with us before sending any sensitive or confidential artwork or material.
How data is used
Information is used to respond to inquiries, assess and prepare quotations, communicate about samples and orders, maintain inquiry and transaction records, secure and operate the site, prevent abuse, and meet applicable legal or contractual obligations.
No automated decision-making producing legal or similarly significant effects is applied to your information through this site.
This notice does not claim any marketing use. Separate permission is required before any optional marketing messages are sent.
Legal basis
Processing may be necessary to take steps requested by you before entering into a contract, may rely on legitimate interests in answering business-to-business inquiries and protecting the site, or may be needed to meet legal or contractual obligations. The applicable basis depends on your jurisdiction and the specific transaction.
This notice is not legal advice.
Sharing and international handling
Your information may be accessed by personnel supporting the confirmed manufacturing and international contracting roles, and by hosting, database, email and security service providers, only to the extent needed for those functions.
Because operations involve Shenzhen and Hong Kong and visitors may be located elsewhere, information may be handled across borders subject to applicable safeguards. This notice does not name unverified vendors and does not claim any specific adequacy decision or certification.
Retention
There is no fixed retention duration in this notice. Inquiry and transaction records are kept only as long as reasonably needed to review the request, administer a transaction, resolve disputes, protect security and meet applicable legal or accounting obligations. Records are then deleted or anonymized where appropriate.
Actual retention should be reviewed periodically as processing and obligations evolve.
Your choices and rights
You may request access, correction or deletion of your information and, where applicable, restriction of processing, objection to processing, data portability or withdrawal of consent by emailing magnet@guangdongcs.com. These rights depend on applicable law and its exceptions, and you may complain to your competent supervisory authority if you believe your rights have not been respected.
The required Request a Quote fields are needed to review a request. If you prefer, you may email our team first instead of submitting the form.
Cookies and analytics
This current site does not intentionally run marketing analytics or advertising trackers. Hosting and security providers may use essential storage or technical logs needed to deliver and protect the site.
This notice does not claim that no cookies or technical storage are ever present.
Children
This is a business-to-business website and is not directed to children. We do not knowingly request children’s data through the Request a Quote form.
Changes and contact
This notice may be updated when processing changes. For any privacy question or request, contact our team at magnet@guangdongcs.com. See also the Contact page and the Website and Quotation Terms.
