Gmail tracks the history of things you buy, and it’s hard to delete

Google tracks a lot of what you buy, even if you purchased it elsewhere, like in a store or from Amazon. I made these purchases using online services or apps such as Amazon, DoorDash or Seamless, or in stores such as Macy’s, but never directly through Google. Google even knows about things I long forgot I’d purchased, like dress shoes I bought inside a Macy’s store on Sept. 14, 2015.
