Want to start new tracker

Hi,

Fairly new here, but I have a question that you folks might be able to help me with.

I want to start a membership tracker that deals in a certain segment.

I just need to know how to set it up and host it where I won't get into any "legal" trouble since I'm in the U.S., land of the slave.

Where would I host it, how to pay for hosting, etc., wihtout having to worry about 3-letter agency goons at my door.

If there's already another thread on this, kindly scold me and point me in that direction:(

Thanks for your help.
