Looking for a privacy-focused eCommerce solution, any ideas?

Heya All, I'm currently in the process of setting up a small eCommerce store to sell a book about Big Data. I would love to have no 3rd party cookies (or at least none from FB or Google) but every solution I can afford has built-in analytics and FB pixels. So far I have tried many "buy buttons" and wasted a lot of time experimenting with Gumroad and Payhip. Surely there is a system like Gumroad, that doesn't force my customers to be tracked. Any help or suggestions would be appreciated, ThanKs
