Any examples of indie devs burned by that danger? Don't do shady stuff and you will be fine and if you do shady stuff and push for edge cases and interpretation ambiguities to run your business then study the laws in details and lawyer up. The basics are simple enough to run a legit business. There are some obvious and basic data protection requirements but I wouldn't call a gray zone unless pushing for it. Also, there's no EU police checking apps for violations etc. You don't just get sued the moment your app hits the App Store.
