Yes I have created a script that shows buy and sell signals. I want it to sell on monthly subscription. My concern is if someone took subscription from me and shared that id with another people then? And also If live account is not associated with it then he can share. That is why I want to restrict...

I have one invite only script but when I log in 3 android devices with same ID... I can use that invite only script on all three devices..
How I can restrict it for only one device?

Thanks
Suhas
