TheraPunktur review for Fueled Attribution Suite

I am a bit worried about the rights this app might have regarding data protection/sharing. If I understand this correctly, this app can use all store data, that flows through this API Google Analytics GA4 stream for their business and also give/sell it to 3rd parties. This would mean, by using this app customers agree that Fueled can use customers shop data and customers, customer data for their own purpose. If so, this would be a huge deal. This could then affect customers very negatively, if this data goes into wrong hands. And even create competitors. Please correct me if I understood something wrong. Thank you.
