It has been written and said a lot about MyHeritage. I do not spend time on this here, but the fact is that some would like out of this system, but have no idea how to take care of family their data is located there.
There are an extension called GEDCOM (Genealogical Data Communications). With this you should be able to move genealogy of your information from a related program to another. Unfortunately it's a little different interpretations of the data, so it is not always that all information are not placed where they should be.
