Question about startapp ads and personalized ads for European users

i think about to use startapp ads in my app, because i got some trouble with admob ads policies. My Problem is, that i need a possibility to ask users from the european Union, if they want personalized ads or not. I dont find a Feature for this in the startapp component. Maybe you can add this Feature in the near Future? Or Is there a possibility to implement it in other ways? Or maybe do i need it really for the EU? Is the law very clear in this case?
Many thanks and many greetings
