I had few ideas now and then, but I kept always thinking about one step that held me back - how do I get the right T&C and Privacy policy? Need to mention I'm from Poland and I guess it must be way different by law standards than it's in the US - take the GDPR alone but then a lot of hassle with local tax office... It just seems quite costly to just try an idea. What should I do to get it right? Is it possible to get an US or other entity just to be able to have some kind of relaxed paperwork?
