Privacy Notice
This notice applies to contact details, technical materials and necessary service records used when visitors consult Maisi Zhiwei or request technical support, on-site work or project delivery.
1. Information we may process
To assess an issue and arrange service, we may ask you to provide business location, contact details, screenshots, equipment models, server versions, a high-level network description, masked IP ranges, error messages and business-impact information. Please do not submit unrelated personal or sensitive information.
2. Purpose and use
Information is used only to assess the issue, confirm scope, arrange remote or on-site work, communicate about the project, design a solution, validate implementation and maintain necessary delivery records.
3. Remote support and least privilege
Remote sessions should be initiated or explicitly authorized by the customer and limited to the agreed scope. For sensitive environments, use redacted data, temporary accounts and least-privilege permissions, and revoke or rotate credentials after completion.
4. Retention and security
Information actively provided through communication channels is retained only for as long as reasonably necessary for the service purpose, project performance, dispute handling and applicable requirements. When continued retention is no longer necessary, it will be deleted, cleared or anonymized as appropriate.
5. Third-party communication platforms
If you choose to communicate through WeChat, email or another third-party platform, that platform may process information under its own rules. Project materials are not normally provided to unrelated third parties except where necessary for an authorized service, legal compliance or explicit authorization.
6. Passwords and sensitive configurations
Do not send administrator passwords, private keys, complete sensitive configuration files or production data through ordinary chat. Where temporary credentials are necessary, use short-lived, least-privilege access and revoke or rotate it after service completion.
7. Your requests
You may request access, correction, supplementation or deletion of materials you provided, withdraw non-essential authorization, or ask us to stop further contact through the website Contact page. Requests will be handled after reasonable verification and according to the applicable service relationship.
8. Updates
This notice may be updated when service scope, information-handling practices or applicable requirements change. The latest version published on this website applies.
