Contract and pre-contractual steps
When processing is necessary to respond to your quotation request, prepare a customized solution, process an order, or perform our obligations under a business relationship.

Legal obligations
Where information must be processed or retained to comply with applicable laws, regulations, accounting requirements, tax obligations, legal claims, or government requests.

Our website may use cookies and similar technologies to operate properly, understand website usage, remember preferences, measure performance, and support advertising activities.
These technologies may include:
Essential technologies
Used for website functionality, security, forms, and other services necessary for the website to operate.
Analytics technologies
We may use analytics services such as Google Analytics and similar tools to understand how visitors interact with our website. These services may collect information such as session activity, approximate location, browser and device information, traffic source, and website interactions.

We may use Google Ads and other advertising or measurement services to understand advertising performance, measure conversions, and improve our marketing activities.

For OEM, ODM, customized, and private-label projects, we treat customer drawings, specifications, branding information, and project information as confidential business information and do not disclose such information except where necessary to fulfill the project, provide requested services, or comply with applicable law.
Depending on applicable privacy law and the configuration of advertising technologies used on our website, certain disclosures to advertising or analytics providers may be treated as “sharing” or targeted advertising. Where required, users will be provided with appropriate choices or consent controls.
6. International Data Transfers
Nanjing Diamond Hope Machinery Trading Co., Ltd. is located in China and serves customers and website visitors in different countries and regions.
As a result, information you provide to us may be transferred to, accessed from, or stored in countries other than the country in which you are located.
Some of our service providers may also process information in different countries.
Where international transfers are subject to applicable data protection requirements, we take reasonable steps to use appropriate contractual, technical, organizational, or other legally recognized safeguards where required.
7. Data Retention
We retain personal information only for as long as reasonably necessary for the purposes for which it was collected and processed.
The appropriate retention period may depend on:
-
The duration of our business relationship
-
The status and history of inquiries or projects
-
Order fulfillment and shipping requirements
-
Warranty and after-sales service requirements
-
Customer support needs
-
Accounting, tax, customs, and legal obligations
-
The need to maintain appropriate business and transaction records
-
The establishment, exercise, or defense of legal claims
-
Applicable statutory limitation periods
Business and order records may therefore be retained for longer periods where reasonably necessary for ongoing customer relationships, repeat orders, warranty service, legal compliance, accounting, dispute resolution, or legitimate record-keeping purposes.
Information used solely for marketing purposes will no longer be used for such purposes after you unsubscribe, withdraw consent where applicable, or otherwise exercise a valid right to object.
When personal information is no longer reasonably required, we may delete, anonymize, or securely archive it in accordance with applicable requirements.

You may unsubscribe or object to direct marketing communications at any time by using the unsubscribe method provided in the communication or by contacting us.
Opting out of marketing communications will not prevent us from sending necessary communications relating to an existing inquiry, quotation, order, shipment, warranty matter, or other business relationship.
9. Data Security
We take reasonable technical and organizational measures designed to protect personal information against unauthorized access, misuse, alteration, disclosure, loss, or destruction.
These measures may include access controls, secure systems, HTTPS encryption, restricted employee access, and other appropriate safeguards.
Access to customer information is limited to employees and service providers who reasonably need the information to perform their duties or provide relevant services.
However, no website, electronic transmission, or data storage system can be guaranteed to be completely secure. We therefore cannot guarantee absolute security of information transmitted or stored electronically.
