>they aren't able to read your emails or use them as training data for an LLM.

I'd love to see the policy or law that prevents Google from doing either.

I don't see anything that prevents them from feeding your emails into an LLM.

I do see:

"We use data to build better services"

"We restrict access to personal information to Google employees, contractors, and agents who need that information in order to process it."

Let's reverse the question; do you see anything that explicitly grants them permission to feed emails into an LLM?
