Some Pre Sale Question / Usage question

Hi guys,

I really like your hack and maybe will I buy it soon. But there's some questions i want you to answer about if possible

1/ How to use the hack safetly? Is there a legit setting you can propose to me? 

2/ If I use the hack just to control the spray and wallhacking, can I get Vac banned even if I play very legit? I mean can i get vac banned even if i NEVER rage?

3/ Can I play as much games i want per day or there's a number of games to not cross? 

4/ I have a gold nova 4 account with 800 hours, and Im going to buy an alt account. Do you recommand me to use the hack on my main and play with no cheat on the alt or the opposit?

5/ What is your recommandations to never get Vac banned?

6/ Is there some explications of the settings of the hack?

Thank your for reading me.
Hope to recieve an answer as soon as possible. :)
