This policy explains how BOAO handles information when you browse the website, use AI enquiries, leave a message or upload project materials, and how you can exercise your choices and rights.
1. Scope and contact details
This policy covers browsing, AI enquiries, visitor messages and inquiry attachments on the website of Hangzhou Dazhong BOAO Technology Co., Ltd. (BOAO or we). BOAO is responsible for the processing of personal information for these functions.
You may browse without submitting your name or contact details. AI enquiries and visitor messages are optional. The information needed for each function is described below. Contact us using the email address or phone number at the end of this page to request access, correction, deletion or withdrawal of consent.
2. Information collected by each function
We collect information needed for the functions you use. A visitor message requires either a phone number or an email address. Additional details such as company, country or region, product interest and attachments are optional as indicated on the form.
- Messages and inquiries: name, phone number or email address, project requirements, and additional company, country or region, product interest and project-stage details you choose to provide; submission time, source page, associated product and handling records are also stored.
- Attachments: drawings, plans, images or other permitted files you choose to upload, together with the original filename, file type, size and necessary technical information.
- AI enquiries: your questions, relevant conversation history, AI replies, references, conversation times, and necessary usage and failure records. A successfully submitted message may be linked to its conversation to help review the requirements.
- Operation and security: IP address, browser and device type, access times, session identifiers and necessary request records to deliver pages, limit abnormal requests and investigate faults.
- Website statistics: a random browser identifier, pages visited, referring website, device category, foreground active time, and events such as an enquiry or successfully saved message. Statistics do not contain names, phone numbers, email addresses entered in forms or attachment contents.
3. Purposes and grounds for processing
This information supports the functions you choose, product guidance, storage and review of project requirements, communication about your inquiry, and website and service security. Statistics help us understand interest in pages and products, use of enquiry features and website quality. They are not used to make individual quotations, credit assessments or other automated decisions with significant effects.
We process information on grounds available under applicable law, such as necessary consent, steps requested before entering a contract, performance of an existing contract or legal obligations. Unrelated information is not a condition of use, and browsing does not constitute consent to all processing of personal information. Processing requiring additional authorization must be explained and authorized separately.
You can browse and use AI enquiries without providing contact details. A message cannot be saved without the necessary contact name, contact method and requirements. We do not sell your personal information or use an inquiry alone as permission for unrelated marketing.
4. AI enquiries and DeepSeek
AI enquiries use the official DeepSeek model API. When you send a question, our server sends the question, relevant conversation context and retrieved public company information to DeepSeek to generate a reply. The provider handles these requests under its applicable terms and privacy rules. You can consult the official DeepSeek Privacy Policy.
Names, phone numbers, email addresses and attachments entered in the message form are not automatically sent to the model as question-and-answer content. Administrator accounts, passwords, API keys and non-public materials are not supplied as customer-service knowledge. If you include personal or confidential information in a chat message, that text may be sent with the enquiry. Please focus on product questions and necessary project conditions.
AI does not replace formal commercial or engineering confirmation and does not place orders, make payments or perform business actions for you. You may stop chatting and use the message form or the contact details listed on the website. Conversations are not displayed publicly to other visitors.
Official DeepSeek Privacy Policy
5. Website statistics and your choices
The website uses its own statistics system. A random browser identifier estimates visitors and visits; enquiry and message events help us understand the use of contact features. The identifier is not your real identity and cannot reliably distinguish individual people. Referral statistics retain the referring website, not the full query contents of a referring URL.
Statistics do not read form contents, request location permission or create identity-based advertising profiles. When your browser sends a Do Not Track or Global Privacy Control signal, the website skips the corresponding visit, enquiry and message-event statistics. Necessary security protection and enquiry or message functions you choose to use can still operate.
Use your browser privacy settings to manage cookies and site storage. You can browse public pages without using AI or submitting a message. To correct or delete information you have submitted, use the contact details at the end of this page.
6. Service providers and access to information
Within BOAO, access is limited to authorized personnel who need the relevant information. Website development and maintenance providers may access information only as necessary to perform their services and must protect its confidentiality and security.
Hosting and network acceleration use infrastructure services such as Alibaba Cloud for hosting, page delivery and security. AI replies use DeepSeek with the request contents described above. If email notifications are enabled, the mail provider processes the recipient address and inquiry-notification content needed to send them. Disabling notifications does not prevent messages from being saved in the website administration system.
Information is not provided arbitrarily to other parties beyond the functions you choose, legal obligations or necessary security protection. Where separate notice, separate consent or another legal procedure is required, this policy does not replace that procedure.
7. Cookies and browser storage
Necessary session cookies support forms, security checks and administrator login. Opening the chat also uses a random visitor cookie to bind conversations, prevent other visitors from reading them and limit misuse. The chat visitor cookie lasts about 30 days.
Browser storage may retain a random conversation credential and window state so you can resume after refreshing or changing pages. It does not store names, phone numbers or email addresses from the message form. A conversation can be restored for up to 24 hours from its creation; further replies stop when its message limit is reached.
The random statistics visitor cookie lasts about 30 days. The visit-session cookie lasts about 30 minutes and is renewed during normal activity. Blocking or clearing necessary cookies and site storage may affect conversation recovery, security verification and some forms. Public pages remain available. After using a shared device, consider clearing this website's cookies and storage to prevent another user from restoring your conversation.
8. Retention and deletion
Detailed visit statistics are managed within a 90-day retention window, and server resource samples within a 30-day window, with scheduled batch cleanup. Expiry of a cookie or conversation credential does not mean all server-side business records are deleted at the same time.
The 24-hour conversation period controls how long a visitor can restore a chat; it does not automatically delete administration records of chats and messages. We retain these materials only as needed to handle your enquiry, conduct related business, resolve disputes or comply with legal obligations, and remove unneeded content through the record-management process. You can request earlier deletion using the contact details below.
Information that must be retained by law or is necessary for an existing dispute is kept only for that purpose and handled when the applicable period ends. Clearing message content does not require deletion of the minimum records needed for cost reconciliation or to demonstrate handling outcomes; such records do not retain the contact details or requirements text that have been cleared.
9. Access, correction, deletion and withdrawal
Subject to applicable law, you may request access to or a copy of your information, correction of inaccuracies, deletion of information no longer needed, and withdrawal of authorization for consent-based processing. Other applicable rights can also be exercised through the contact details below.
Describe your request and provide a message reference, submission time or the contact method used to help locate the record. To prevent unauthorized access or deletion, we may verify your identity in a necessary and proportionate way without requesting unrelated sensitive materials. We handle verified requests according to law and explain any reason we cannot fulfil a request.
Withdrawal does not affect processing lawfully carried out beforehand. If information is necessary to complete a function you request, that function may no longer be available; other functions that do not require it are unaffected.
10. Security and sensitive materials
We protect information with HTTPS transport, administrator permissions, restricted attachment access, conversation binding and abnormal-request controls. No transmission or storage method is completely secure. Relevant security incidents are handled with the notifications required by applicable law.
The website does not need identity documents, bank-card details, account passwords or equipment-control credentials. Do not put them in chat messages or attachments, or upload unauthorized third-party materials or sensitive information unrelated to the project.
11. International access and third-party links
BOAO is located in China, and the website's main business records are stored on servers in China. Enquiries or messages submitted from outside China are transmitted to China for processing. Page acceleration may use network nodes in different regions to process request information needed for page delivery. Any cross-border provision of personal information must first meet applicable notice, consent and other requirements.
You choose whether to open external messaging, social-platform or other links. The destination service is operated by its own provider under its own terms and privacy rules.
12. Information about minors
This website primarily serves business and engineering-project enquiries and is not directed at minors. Do not submit information about minors unrelated to a project. If such processing is necessary, the authorization and safeguards required by applicable law must be provided.
13. Policy updates
We update this policy when website functions, processing purposes or service providers change and show its effective date on this page. Material changes affecting your information rights require appropriate notice. Updating the text does not replace renewed authorization where law requires it.
