Does Google still hold contact data after deleting from Google Contacts? - eviltoast

I am in the process of moving out some contacts from Google Contacts, specifically those that I do not have a Gmail address. It’s a way for me to give these people a tiny bit more privacy, as I’m doing a cleanup of my contact list. My concern is that Google will still keep their data even after I delete it from my end. Is it so? Or does removing a contact really delete it from there?
