¿ How does the profit guarantee works?

I am going to pay for three months of the starter suscription ( 252 euros aporximately ). My question is that if the first month my profit is under 0 euros, i will get another month for free right, always making bets of 3.0 max odds, placing more than 500 bets per month and 1,5% max stake and 30% kelly section.
