Privacy Policy

LenQuant provides AI-powered trading analysis tools designed to help traders make more informed decisions. We are a decision support tool, not a signal service, and we do not execute trades on your behalf.

Google Analytics: We use Google Analytics to understand how users interact with our website. This uses cookies and collects anonymized usage data. See Google's Privacy Policy.
