Received an email from Google Fi that their policy is to “opt you in” to sell your phone-call and purchase info to advertisers. They call the data your CPNI — “Customer Proprietary Network Information”. Making this an opt-out when it’s a combo of your shopping data plus phone-call data (including destination and location) plus Google identity seems pretty egregious to me.

Anyway, the emailed notice is easy to overlook as just another policy update that you wouldn’t do anything about. But you can opt out.

At https://fi.google.com/account, go to “Privacy & security”, and deselect “Allow CPNI sharing”. It’s not in the Fi app; you have to do it in a browser.
