How to not being tracked by anyone in stock market

#1
Hello.
If i purchase direct nse line?
are they going to provide me a software like zerodha trader? or odin or what type of?
Sorry this is a stupid question but I am new to all this.
And most importantly if i trade directly line from nse, am i 100% full proof that i am not being tracked?

And whats the price of taking a direct line.? is there any sort of jugaad when it comes to taking membership ( price)
Also how many members can trade if i buy one line, because i may partnership with someone so the cost become less.
Also it would be so great if you can write your comment in hindi as my english is weak. ( hindi words in English fonts)
