where does 6 months included support money go ?

i’m pretty new i’m evanto market place. i have a question about 6 month included support.
When customer checked 6 month support they need to pay extra money. I want to know where the money goes,
does the author get the money or evanto takes it ?

Included support is included in the price. If they go for six months extra or renew it at a later date, 70% goes to you, 30% goes to Envato.
