1.2 Transaction Data. We record all trading activity, deposit and withdrawal transactions, order history, account balance snapshots and settlement records associated with your account. Transaction data is necessary for providing our services, fulfilling regulatory reporting obligations and resolving disputes.
1.3 Device and Usage Data. When you access the platform, we automatically collect technical information including your IP address, browser type and version, operating system, device identifiers, screen resolution, referring URLs, pages visited, time spent on pages, click patterns and session duration. This data helps us maintain platform security, detect unauthorized access attempts and improve user experience.
1.4 Cookies and Tracking Technologies. We use essential cookies required for platform functionality (session management, authentication state, security tokens), analytical cookies to understand usage patterns and optimize performance, and preference cookies to remember your settings. We do not use advertising or tracking cookies. You can manage cookie preferences through your browser settings, though disabling essential cookies may impair platform functionality.
1.5 Biometric Data. During identity verification, we may process facial recognition data to match your selfie against your government-issued ID. Biometric data is processed in real-time on our infrastructure, is not stored permanently after verification is complete, and is never shared with third parties.
