- No expiry

Log inStart a simulationESYou pay per simulation. You can try it free: the first five replies are not charged and you do not need an account. No subscription, and the credit is only used once you confirm which decision you want to test and we start simulating.
Charged in US dollars, through PayPal, which processes the payment. We are the seller and the one issuing the receipt, same as in pesos.
01
Not when the conversation opens. You can prepare your simulation, review data and correct numbers without using it: it is used once you confirm which decision you want to test.
02
If you cancel before we start simulating, or leave it 72 hours without activity before starting, the credit returns to your balance on its own. Once we have started, it has been used.
03
So you can be in one, not half-way into four. When one closes, you start the next.
04
No monthly charge, no auto-renewal. You buy what you are going to use and that is it.
Prices include taxes. They may change going forward: a change never affects a purchase already made or credits already granted. By buying you accept the terms and conditions and the refund policy.
