2. Information we may collect
2.1 Online enquiry information
When you voluntarily submit an online enquiry, we may collect:
- Name
- Organisation or company name
- Phone
- Email address (if provided)
- Project location
- Enquiry type
- The requirements description you voluntarily provide
We collect only the information necessary to handle your enquiry and conduct subsequent business communications.
2.2 Website operation and security information
To support normal website operation, security protection, troubleshooting, and necessary traffic statistics, the server may automatically record limited technical information, such as:
- Request time
- Requested page or resource
- Network address
- Basic browser and client information
- HTTP status code
- Security incidents and anomalous access records
3. How we use information
We may use relevant information for the following purposes:
- Responding to enquiries you voluntarily submit
- Understanding project requirements
- Communicating with you about business matters
- Assessing potential opportunities for cooperation
- Providing service information you request
- Maintaining normal and secure website operation
- Troubleshooting system faults
- Preventing malicious access, attacks, and spam submissions
- Complying with applicable laws and regulations
- Protecting the lawful rights and interests of the company or relevant parties when necessary
4. Consent for online enquiries
Before an online enquiry is submitted, the following statement is clearly displayed near the submit button:
“I have read and agree to the Privacy Policy, and I consent to MK Data Technology processing the information I voluntarily submit in order to handle this enquiry.”
This option:
- Must not be selected by default
- Must prevent submission until the user actively confirms
- Must provide a direct link to the Privacy Policy
If personal information processing beyond the current enquiry purpose is introduced in the future, we will reassess whether additional notice or consent is required.
5. Do not submit sensitive or confidential information
The public website contact form is not intended for sensitive, confidential, or strictly protected information.
Do not submit the following through the public website:
- State secrets or other classified information
- Unauthorised internal documents of governments, public institutions, or companies
- Patient records or medical and health data
- Identity card, passport, or similar identification information
- Bank account or payment information
- Account passwords or system access credentials
- Trade secrets
- Non-public source code
- Other highly sensitive information
If a formal project requires the exchange of such materials, it should take place through a secure channel separately agreed by both parties.
6. Information retention
For personal information used solely for website business enquiries, and where there is no subsequent business cooperation, contract performance, or other legal retention requirement, we generally retain it only for the period necessary to complete the enquiry communications.
Ordinary enquiry information is generally retained for no more than 12 months after the last substantive business communication.
When that period expires and continued retention is unnecessary, the information should be deleted or processed so that a specific individual cannot be identified.
If an enquiry develops into a contract, project, financial record, project archive, or other formal business record, relevant information may be retained separately as required for contract performance, financial and records management, dispute resolution, and compliance with laws and regulations.
7. Location of information storage and processing
The domestic website is primarily deployed on cloud servers located within the People’s Republic of China.
The first version of the website gives priority to information processing and notification channels located within China.
Without a dedicated compliance assessment, personal information collected through the domestic website should not be automatically sent, synchronised, or backed up to services outside China.
If future business genuinely requires cross-border provision of personal information, a separate compliance assessment will be conducted and applicable legal obligations fulfilled before the relevant feature is enabled.
8. Service providers
To provide the infrastructure needed for website operation and enquiry delivery, we may use necessary technical services such as cloud computing, domain-name resolution, network security, SSL certificates, corporate email, and email delivery.
The first version of the domestic website is planned to use infrastructure primarily provided by Tencent Cloud.
Where a third party processes personal information on our behalf, we will manage its permissions, processing scope, and security measures as necessary for the actual processing activity.
9. Cookies, analytics, and advertising tracking
The first version of the domestic website does not plan to use:
- Advertising-tracking cookies
- Meta Pixel
- Google Analytics
- LinkedIn Insight Tag
- Cross-site behavioural tracking
- Device or user fingerprinting
- Personalised advertising systems
The website may use technical mechanisms necessary for essential functionality, security, and network transmission.
Under the current design, the first version does not provide a separate Cookie Policy.
If non-essential cookies, advertising analytics, user profiling, or other personal-information processing technologies are introduced in the future, the Privacy Policy and notice mechanism will be reassessed before they are enabled.
10. Information security
We take reasonable security measures appropriate to the scale of the website and the risks of information processing, including:
- HTTPS encrypted transmission
- Access controls
- Server and application security updates
- Firewalls
- Network operation and security incident logs
- Data minimisation
- Necessary backup and recovery measures
- Restricted access to contact information
- Security incident response mechanisms
No internet environment can be guaranteed absolutely secure, but we take protective measures appropriate to the actual risks.
11. Your rights
Within the scope provided by applicable laws and regulations, you may make the following requests regarding personal information about you that we process:
- Access
- Obtain a copy
- Correction or supplementation
- Deletion
- Withdrawal of relevant consent
- Restriction of or objection to specific processing activities
- Enquiries about, or requests for an explanation of, personal information processing rules
You may use the following contact details to request access, correction, deletion, withdrawal of consent, privacy enquiries, or other personal information rights available by law:
- Privacy contact phone
- 18007488662

We may need to verify the requester’s identity by reasonable means to prevent unauthorised action on your information.
12. Minors
This website is primarily intended for governments, public institutions, companies, and other professional and business clients. It is not directed at minors.
Minors should not voluntarily submit personal information through this website.
If we discover that a minor’s personal information has been collected unnecessarily, we will handle it in accordance with applicable laws and regulations.
13. Third-party links
This website may provide links to third-party websites.
Third-party websites have their own operators and privacy rules. MK Data Technology does not control their personal information processing activities.
Before visiting a third-party website, please review its privacy policy and terms of use.
14. Updates to this Privacy Policy
We may update this Privacy Policy if website features, personal-information processing practices, service providers, or applicable requirements change.
