Flip any category free independently — signups made while a toggle is on stay free permanently, even after you switch it back off. Only new signups from that point are affected.
💡 Turning a toggle off does not charge anyone. It only stops new
free signups from that point on. To actually move existing free members onto
paid billing, set a pending notice below (shown on their dashboard) — the real
billing switch is a separate, deliberate step done later, never automatic.
