title: where are power BI desktop data being stored: local on my laptop or in the cloud?
body: <p>I want to test Power BI desktop (free). I want to test with some hospital data. But.... I can and will do this only, when all data are stored local.</p>
  <p>For some reason I can't find a 100% answer to this question from Microsoft itself. Hopefully someone here knows the answer.</p>
  <p>Many thanks! greetings Jan.</p>
