Google promised not to show ads based on your emails. AI could undo that

Since 2017, Google has promised not to show ads based on users’ Gmail messages. While that policy isn’t changing today, Google may be laying the groundwork for personalized ads based on AI insights from users’ inboxes. Google’s support documents already acknowledge that it may show ads based on users’ interactions with AI, and with new Personal Intelligence AI features in Google Search, those interactions can now include data from Gmail.
