#GoogleFi users!!
#DataPrivacy#Google "opted you in" to sell your phone-call and purchase info to advertisers via what they call your #CPNI — your "Customer Proprietary Network Information". Their emailed notice is easy to overlook as just another policy update that you have little choice but to accept. You have a choice!
Opt out at https://fi.google.com/account, go to "Privacy & security", and deselect "Allow CPNI sharing".
You have to do it in a browser; they don't let you do it in the Fi app.
