Nope, that's not how it works. They can simply sue you in the jurisdiction in which you live, getting a court order for you to reveal the information. Details of where it is hosted doesn't matter.
Unless you don't mind serving indefinite jail time for contempt of court.

Not how it works internationally, this looks more like a US-centric view of the world. I believe in most countries courts would not do that at all. If you want an example, look how nobody can sue Snowden in Russia.
They are not cheap. Pick your countries right and arguably you would be hard to sue.
IANL but you should consult one when implementing this strategy.
