We collect information that you choose to submit, limited technical information needed to operate the website, and measurement data that helps us understand site use. We use it to answer B2B inquiries, provide requested technical resources, support product evaluation, secure the site and improve its content. We do not ask you to place confidential engineering data or sensitive personal information in the AI chat.
01 · Scope
Scope and data controller
This Privacy Policy applies to personal information processed through drones-lidar.com, including its contact and technical-resource forms, product and documentation pages, account or order functions when available, AI customer-support interface and related website services.
Guangzhou Purpleriver Electronic Technology Co., Ltd., operating the Purpleriver brand, is the controller responsible for the website information described in this policy. This policy does not govern third-party websites or applications that you choose to open from our site.
02 · Collection
Information we collect
Name, business email address, telephone or WhatsApp number, company, account identifier and similar contact information that you provide.
Application scene, target platform, preferred interface, target distance, host system, project schedule, purchase quantity, technical requirements and messages.
Contact-form messages, technical-resource requests, AI-chat prompts and responses, conversation identifiers, support status and related correspondence.
Where account or order features are used: account details, requested products, order number, status, billing contact and transaction-related records. Payment-card details are handled by the applicable payment provider rather than stored in this page template.
Browser and device type, approximate location derived from network information, pages and links viewed, referral information, session statistics, cookie identifiers, timestamps and diagnostic or security logs.
Whether a documentation or dataset request was completed, the requested resource category, and a short-lived first-party access marker used to continue the requested download flow.
We normally obtain this information directly from you, automatically from your browser or device, or from service providers that help deliver the website. Please do not submit government identifiers, financial-account credentials, health information or other sensitive personal information unless we specifically request it through an appropriate secure process.
03 · Purpose
How and why we use information
The AI assistant supports customer service and does not make decisions that produce legal or similarly significant effects about you. Important technical, commercial and contractual decisions are reviewed by people.
05 · AI support
AI customer-support conversations
When you use the AI customer-support tool, your message, a pseudonymous visitor identifier, conversation identifier, timestamps and the assistant response are transmitted to the website and the AI service used to generate the response. Conversation records may also be stored in our WordPress database so the support team can review context, continue service and diagnose delivery issues.
Do not place trade secrets, source code, credentials, export-controlled information or sensitive personal information in the AI chat. AI output may be incomplete or inaccurate; verify specifications and commercial commitments with the Purpleriver team before relying on them.
06 · Recipients
How information is shared
We may disclose relevant information to the following categories of recipients only as needed for the purposes described above:
- Website hosting, security, email, WordPress, form-delivery and technical-support providers.
- Google Analytics for website measurement and reporting.
- The AI-platform provider used to process and return customer-support responses.
- Payment, order, logistics, professional-adviser or business-service providers when a transaction or legal need requires them.
- Government authorities, courts or other parties when disclosure is required by law or reasonably necessary to protect rights, security and users.
- A successor or transaction counterparty in connection with a merger, financing, acquisition, reorganisation or transfer of business assets, subject to appropriate confidentiality measures.
Purpleriver does not sell personal information for monetary consideration. We do not knowingly sell or share personal information of people under 16. If you choose the WhatsApp button, you leave our website and your communication is governed by WhatsApp's privacy policy.
07 · Locations
International data transfers
Purpleriver operates from China and serves customers internationally. Information may therefore be processed in China and in other countries where our hosting, analytics, communications, AI, commerce or support providers operate. Privacy laws in those countries may differ from the laws where you live.
Where applicable law requires a transfer mechanism or additional safeguard, we will use an appropriate contractual, organisational or legal measure for the relevant processing.
08 · Storage
Retention and security
We keep personal information only for as long as reasonably necessary for the purpose collected, including project follow-up, customer support, account or order administration, security, recordkeeping and legal requirements. Retention depends on the relationship and record type:
- Inquiry, quote, sample and technical-support records may be kept through the evaluation or commercial relationship and for a reasonable follow-up and legal-record period.
- AI conversations may be retained while needed for support continuity, quality review, security and dispute handling.
- Account, order, tax and transaction records may be retained for periods required by commercial, accounting or other applicable law.
- Google Analytics event and user-level data follows the retention settings configured for the Analytics property; aggregate reports may remain after user-level data is deleted.
We use reasonable technical and organisational safeguards, including encrypted website transport, access controls, input validation and security logging. No internet transmission or storage system is completely secure, so absolute security cannot be guaranteed.
09 · Choices
Your privacy rights
Depending on where you live and which law applies, you may have the right to request access to personal information, correction, deletion, restriction, portability, objection to certain processing, or withdrawal of consent. Withdrawal does not affect processing that was lawful before withdrawal. You may also have the right to complain to the data-protection or privacy authority in your country or region.
Applicable US state laws may also provide rights to know the categories and specific pieces of information collected, correct or delete information, obtain a portable copy, opt out of certain sales, sharing or targeted advertising, limit certain uses of sensitive information, and receive equal service without unlawful discrimination. These rights apply only where the relevant law covers the processing.
To make a request, email [email protected] with the subject “Privacy Request” and describe the request and the website interaction involved. We may ask for information reasonably necessary to verify identity and protect records from unauthorised disclosure. An authorised agent should provide proof of authority where required.
10 · Other services
Children and external links
This B2B website is intended for business and technical users and is not directed to children under 16. We do not knowingly collect personal information from children under 16. Contact us if you believe a child has submitted personal information so that we can review and delete it where appropriate.
Links to WhatsApp, Google services or other external websites are provided for convenience. Those services control their own processing, cookies and security practices. Review their privacy information before submitting data to them.
