2. How We Use Cookies

We use cookies for the following purposes:

  • Security cookies - protect against cross-site request forgery and other attacks
  • Preference cookies - remember your UI settings and engine configuration

2.2 Analytics Cookies (Optional)

We may use analytics cookies to understand how visitors interact with the Platform. This helps us improve the user experience. These cookies collect information anonymously and include:

  • Pages visited and time spent on each page
  • Feature usage patterns
