How to read this policy
We value the information you submit through the website. This policy follows the principles of data minimization, defined purpose and security protection and states the rules currently presented with website forms.
Scope
辉汉科技（上海）有限公司 operates the Datazaar website and is the personal information handler described in this policy. This policy applies to inquiry, trial-request, resource-download and anonymous-analytics features. Third-party websites and services are governed by their own privacy terms.
This website primarily serves enterprise and organizational users. Submit only information necessary for business communication and do not include unrelated sensitive personal information in free-text fields.
Information we collect
We process information only when you use the relevant feature or when it is necessary to protect the website.
- Information you provide: name, company, role, phone number, email, area of interest, business scenario and additional notes.
- Resource-download information: the requested resource, contact information, consent status, request time and submission identifier.
- Security and operating information: access time, referring page, basic browser and device information, and logs required to protect the website and forms.
- Abuse-prevention information: the system may briefly process a client address and retain only an irreversible fingerprint for duplicate detection and rate limiting.
How we use information
We do not use submitted information for automated decisions unrelated to these purposes.
- Respond to inquiries, understand the request and arrange business communication.
- Assess and process trial requests and confirm scenario fit.
- Provide requested resources and record authorization for controlled downloads.
- Detect duplicate or abnormal submissions and protect forms, resources and the website.
- Analyze page and content performance without form content or direct identifiers.
Storage and protection
Retention is limited to the minimum period necessary for inquiries, trials, downloads, anonymous analytics, security or dispute handling. When the purpose has been achieved, cannot be achieved or is no longer necessary, we delete or anonymize the information. If applicable law requires continued retention, or deletion is temporarily technically impracticable, processing is limited to necessary storage and security protection.
We apply safeguards appropriate to the information and processing risk. No internet environment is absolutely secure; if an incident may affect your rights, we will respond according to applicable requirements.
- Protect information in transit through HTTPS and related measures.
- Limit access to inquiry and download records according to role and business need.
- Use irreversible fingerprints for security identifiers and retain necessary administrative audit records.
- Retain information only for the minimum period required for the stated purpose, legal obligations and dispute handling.
Sharing and service providers
We do not sell personal information to unrelated third parties. Service providers processing information on our behalf must use it only for the agreed purpose and apply appropriate safeguards.
- Service providers that are necessary for hosting, email notifications, security or system operations.
- Disclosures required by law, judicial process or an authorized public authority.
- Situations where disclosure is necessary to protect the lawful rights and safety of you, us or others.
Cookies and analytics
The website uses necessary session or local storage for essential functions and anonymous analytics preferences. When anonymous analytics is configured, you can choose essential functions only or consent to anonymous analytics; no events are sent without consent.
Analytics fields are limited to page paths, first landing page, referring domain, UTM parameters, button targets and event time. They exclude names, phone numbers, email addresses, company names, request text and download-form content. Network analytics are also disabled when the browser enables DNT or GPC.
Your rights
Send access, correction, deletion or consent-withdrawal requests to contact@datazaar.cn, identifying the relevant submission and requested action. To protect information, we may need to verify the relationship between the requester and the submission.
Personnel responsible for privacy and compliance at 辉汉科技（上海）有限公司 handle requests within the period required by applicable law. If a request is complex, cannot be fulfilled or is lawfully declined, we will explain the reason.
- Ask whether we hold submission information related to you.
- Request correction of inaccurate or incomplete information.
- Request deletion or restriction where applicable.
- Withdraw consent; withdrawal does not affect processing lawfully completed before withdrawal.
Children’s information
This website is intended for enterprise and organizational users and is not directed to children under 14. A guardian who believes a child submitted information by mistake should contact us.
Policy updates
We may update this policy when website features, data-processing practices or applicable requirements change. Material changes will be communicated appropriately, and the version and effective date will be updated.
