These files may contain personal information, such as names and contact details. Please provide only information necessary for your inquiry and files you are authorized to share.
Technical information. Our website and hosting services may process technical information such as your IP address, browser and device information, requested pages, access times, and error or security logs.
Cookies. Information about cookies and your choices is explained below.
We use information for the following purposes:
Where applicable data protection law requires a legal basis, we rely on taking steps at your request before entering into a contract, performing a contract, complying with legal obligations, or our legitimate interests in providing business services and maintaining a secure website. Where consent is required, we request it, and you may withdraw it at any time.
We use submitted drawings and project files to evaluate your requirements, prepare quotations, and support agreed manufacturing services.
Access should be limited to personnel and service partners who need the information for those purposes, subject to appropriate confidentiality obligations. Please contact us before submitting files if your project requires a separate non-disclosure agreement or special handling arrangements.
Our website uses cookies or similar technologies to support website functions and remember relevant preferences.
Where optional cookies require consent under applicable law, they should be used only after you provide that consent. You can review the available options through the “Update cookies preferences” link on our website. You can also manage or delete cookies in your browser settings. Disabling some cookies may affect website functionality.
Where necessary for the purposes described in this policy, information may be shared with:
When you choose to contact us through WhatsApp or visit an external social media website, that provider processes information under its own privacy policy.
We retain inquiry details, correspondence, and submitted project files for as long as reasonably necessary to respond to your request, manage the related business relationship, and meet applicable legal obligations.
Retention depends on the purpose of the information, whether a project proceeds, and any legal or dispute-related requirements. When information is no longer needed, it should be deleted or anonymized.
You may contact us to request deletion of information or files you have submitted, subject to applicable legal requirements.
CHIHENG Hardware is based in China. If you contact us from another country, the information you submit will be processed in China. Service providers may also process information in the countries where they operate.
Where applicable law requires safeguards for an international transfer, we will use an appropriate lawful transfer mechanism and safeguards. You may contact us for information about the arrangements relevant to your data.
We take reasonable technical and organizational measures appropriate to the information we process to help protect it against unauthorized access, loss, misuse, or disclosure.
No internet transmission or storage system is completely secure. If a personal data breach occurs, we will take appropriate steps to investigate and respond, including notifying affected individuals or authorities where required by law.
Depending on the laws applicable to you, you may have the right to request access to, correction of, or deletion of your personal information. You may also have rights to restrict or object to certain processing, receive a portable copy of your information, or withdraw consent where processing relies on consent.
To make a request, email sales04@chihenghardware.com. We may need to verify your identity before responding. Withdrawing consent does not affect processing lawfully carried out before withdrawal.
You may also have the right to complain to the relevant data protection authority.
We may update this policy to reflect changes in our website, business practices, or legal requirements. The revised version will be published on this page with an updated date.
You can send us any questions to get any information you would like to know, and we will respond to you in extremely short time.
