Privacy Policy

The Service is provided by an individual operator publishing under the brand name “YZ AI / 元筑AI”. Questions, requests and legal correspondence can be sent to 719542959@qq.com.

This policy covers personal information processed when you use yzdesignai.com, including account sign-in, project creation, uploading site media, AI analysis, AI chat, design generation and reporting. It supplements, and should be read together with, our Terms of Service.

We collect only the information that is needed to operate the Service and to deliver the features you ask for:

If you choose not to provide information that a feature requires, that feature may be limited or unavailable.

We do not sell personal information. We do not use the content you upload to train our own models, and we do not share your content with third parties except as described in Section 5.

Where the laws of mainland China (including the Personal Information Protection Law, or “PIPL”) apply, we process personal information on the following bases: performance of the contract between you and us when we provide the Service you request; your consent where required (for example, for optional sign-in methods or cross-border AI processing); our legitimate interests in securing and improving the Service; and compliance with legal obligations.

In other jurisdictions, we rely on the equivalent bases available under the applicable data-protection law. You may withdraw consent or object to processing at any time by emailing us (see Section 14).

Most content you process on the Service is design media rather than information about individuals. Please do not upload personal or sensitive information about identifiable people (for example, recognisable faces or identity documents of third parties) unless you have the right to do so.

We share information only as needed to operate the Service. The following categories of processors help us deliver it; each acts on our instructions and has its own privacy policy describing how it protects data:

Your content is shared with an AI provider only for the purpose of generating the output you requested. Where an AI provider may retain content under its own policies, we select providers and settings intended to keep retention to the minimum needed to deliver results. The processors above are located in a number of countries; see Section 8 on international transfers.

When you mark a project as confidential, we disable the free-form AI chat assistant and cloud text generation for that project, so that the project’s text content is not sent to cloud text-model providers. Vision-based site understanding and image/rendering generation that must process the media you have chosen to upload may still run so that the outputs you request can be produced.

Confidential marking is a project-level control that you manage in the product; it is not a substitute for reviewing what you upload to any service.

The Service uses only functional cookies and local storage: your sign-in session (handled through our authentication provider), your language preference, and small interface preferences such as the state of panels. We do not use advertising, social-media or third-party analytics cookies, and we do not track you across other websites.

You can clear cookies and local storage in your browser at any time; you may need to sign in again afterwards.

To provide the Service, your information may be transferred to and processed in countries other than the one in which you reside, including outside mainland China (for example, where an AI model provider or hosting provider is located). We rely on appropriate safeguards for these transfers, and where the law requires your separate consent for a cross-border transfer (for example under the PIPL), your use of the relevant feature constitutes such consent or we will seek it separately.

For users in mainland China: some AI models used by the Service are hosted outside mainland China. By using AI features that depend on those models, you acknowledge and consent to this processing.

We keep your account and content for as long as you maintain your account, and content for as long as it remains part of a project you keep. Where the product provides deletion controls (for example deleting a project or uploaded asset), deletion removes the corresponding records and stored objects from the Service’s active storage.

Account closure and full deletion of all associated data are currently completed on request rather than through a self-serve control in the interface — please email us (see Section 14) and we will act on your request within a reasonable time, subject to any retention we are legally required to keep (for example billing or audit records).

We do not automatically delete content merely because an account is inactive, and we do not silently remove data without notice where you have an ongoing subscription or balance.

Depending on where you live, you may have the following rights over your personal information:

Currently, full account deletion and data export are fulfilled on request via email rather than self-serve in the interface. We respond to requests within 30 days where we can, and we may ask you to verify your identity first. Contact:

719542959@qq.com

We protect information with encryption in transit (TLS), encryption at rest provided by our storage providers, least-privilege access controls, and session handling through our authentication provider. Because sign-in uses one-time codes or your chosen identity provider, the Service does not store passwords.

No method of transmission or storage is completely secure. Please keep your account secure: do not share your sign-in email and codes with others, and contact us if you suspect unauthorised access.

The Service is not directed to children and is not intended for anyone under 16 years of age (or under 14 in mainland China, as required by the PIPL). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it where required by law.

We may update this policy from time to time. When we make material changes, we will update the “last updated” date above and, where practical, notify you through the Service or by email. Your continued use of the Service after changes take effect constitutes acceptance of the updated policy, except where the law requires your separate consent.

The operator of the Service is an individual publishing under the brand name “YZ AI / 元筑AI”. For privacy requests, support or legal correspondence, please email:

We will respond within a reasonable time (normally within 30 days). If you are in mainland China and are not satisfied with our response, you may also contact the competent authorities responsible for personal-information protection. These terms are governed by the laws of mainland China; for details on governing law and jurisdiction please see our Terms of Service.
