Budapest, in Hungary? You might wanna look up Viktor Orban before moving to there.
If you're British you can roam freely through the EU. I can recommend Germany instead: strong privacy laws, and due to recent history (WWI, WWII, Cold War) there is a relative strong pro privacy mindset. Though I recommend learning German if you intend to settle in large cities such as Berlin and international companies or IT you can easily get away with English.
