Concerning a version without JavaScript we are working on it but you must know that most of our scripts are obfuscated. In any case we understand the fear of some people so we are working on it.

For the delay of 2 to 4 hours everything can depend on if the blockchain is overloaded or not but on average it takes 4 hours if after the time limit you still haven't received anything you can always contact us via our support.

Have a nice day!
