Website and information handling

This website is operated by Guangzhou Meigona Engineering Consulting Co., Ltd. It does not provide website account registration or online payment. Demonstration requests are submitted through a same-origin endpoint to MEIGONA’s backend. Other requirement lists are generated in your browser for you to share. Information sent by telephone, WeChat, email or another channel is subject to that channel’s handling rules.

Xiaoan AI technical assistant

AI processing is on by default and can be switched off at any time. This browser remembers that preference, not your conversation. When AI is unavailable, Xiaoan may provide reviewed guidance for clearly matched questions. Sending a question with AI processing enabled sends your question, up to 8 recent messages, diagnosis progress and any selected redacted screenshot or brief to MEIGONA and DeepSeek. The page distinguishes reviewed guidance, model answers and failed calls. With AI processing off, questions and screenshots are not sent to the model.

Xiaoan does not automatically inspect local software, projects or customer catalogs. Browser conversation stays in page memory. Server diagnosis summaries remain in memory for up to 20 idle minutes, without chat logs; New chat requests deletion. Redacted call records are retained outside the public website directory for 30 days. They contain only request identifiers, stages, timings, error categories, knowledge revisions, citations and token usage, excluding chat text, images and credentials. Provider processing is also subject to its policies.

Optional reply feedback sends only the request identifier, rating and a preset reason. It is retained for 30 days for human review, without conversations or images, and does not automatically update the approved knowledge base.

Opening Xiaoan issues an essential anonymous browser cookie (HttpOnly, SameSite, up to one year) for session ownership and usage allowance. The limit is 500,000 tokens per Beijing calendar day and 1 million over a rolling 7 days. Refreshing or starting a new chat does not reset usage. The server stores only an identity hash, timing and usage, not message text or screenshots; usage details older than eight days are cleaned on subsequent access. Clearing site data, changing browsers or using private browsing may create a new identity. This is not physical-device authentication.

Necessary logs and information protection

For secure operation, the website records access information such as request time, path, response status and source, with restricted operational access. Appointment form contents, chat text, screenshots and credentials are excluded from these logs. Third-party analytics are not enabled, and demonstration information is not used for marketing profiles.

Submit only information suitable for support. Do not upload private customer projects, databases, license codes, production credentials or unpublished internal parameters. Before attaching a screenshot, hide customer names, contact details, credentials and other sensitive information.

Correction, deletion and contact

To ask about, correct or delete your demonstration request, or raise an information-handling question, contact Mr. Zhou at +86 16616656711 (also his WeChat number) or 16616656711@163.com. We first verify that a request relates to the appropriate record to prevent unauthorized disclosure.

This notice will be updated as the service changes. Demonstration records are kept only for contact and scheduling; there is currently no automatic deletion on a fixed retention schedule. You may request correction or deletion through the channels above.

Demonstration request information

The request form collects your name, telephone, format, and optional company, email, preferred time and interests. A city is required for in-person requests. These details are used to arrange this demonstration, without a marketing subscription.

Requests are stored outside the public website directory and accessed by the restricted intake service. Notifications go only to MEIGONA’s designated inbox. A failed notification does not discard a saved request. Details are not passed to Xiaoan, a model or the support knowledge base.

To prevent abuse, the intake service records a one-way identifier of the request source and short-term submission counts. Form contents are excluded from public logs. The form indicates when notification is unconfigured or the service is unavailable and offers telephone or WeChat contact.
