Facebook & Instagram

I understand that certain data needs to be exchanged between my Shopify site and Meta in order to facilitate a purchase. However, like almost every app on this platform - there is no reason an app needs to have access to all of my customer data and more. If I sell 5,000 products and only one order on Facebook, why do they get access to the 4,999 other customer's data? I think too many times folks click through all the 'Accept' buttons and never have a clue that they are opting to literally share all of their customer's private data with a 3rd party. I have a privacy policy that states I will not share customer details with 3rd parties...and I'm going to stick with that.
