Why this exists
One.
Most prop-firm tools are affiliate rails dressed as calculators. We are building the opposite: the tool first, the affiliate disclosure visible, the rule set honest.
Two.
Everything runs in your browser. We do not have your positions, your balance, or your email. Nothing to leak because we store nothing.
Three.
Prop Cockpit™ is a property of FreeTraderHub. We sell tools, not courses, not signals, not Discord access.
