We use Cookies and similar technologies mainly for:

### 3.2 Preference Cookies

These Cookies remember your usage preferences, such as language, theme, table pagination, filter conditions, and whether certain interface modules are expanded.

Disabling preference Cookies may not affect core functions, but it may require you to reset preferences on every visit.

Statistical data is usually aggregated or anonymized as much as possible and is not used to identify specific individuals unless necessary for troubleshooting, security, or compliance.

### 3.4 Security and Third-party Cookies

To protect services, we may use Cookies related to CDN, WAF, security verification, payment, login, cloud services, or third-party model services. These Cookies may be set by third-party service providers for security protection, payment verification, abnormal access identification, or service availability assurance.

The use of third-party Cookies is subject to the policies of the corresponding third parties.

## 4. Types We Currently Do Not Actively Use

Unless otherwise notified and necessary consent is obtained, we do not actively use Cookies to sell personal information, nor do we use Cookies to collect sensitive personal information unrelated to your use of this platform.

If we introduce advertising delivery, remarketing, cross-site tracking, or more complex data analysis tools in the future, we will update this Policy according to applicable laws and regulations and provide necessary choice mechanisms.

Please note that after disabling or clearing Cookies, you may need to log in again, and some console, payment, risk-control, document preference, or API management functions may not work properly.

- Session Cookies usually expire when the browser is closed or the session ends

We adjust retention periods based on service needs, legal requirements, and security risks.
