The new wording says the promise holds "unless you choose to make data from these services available to other Google services that support personalized ads." In practice, anyone using Google's Personal Intelligence feature, which lets AI Mode and other Search tools draw on Gmail, Drive or Photos to give better responses and recommendations, may now see ads shaped by that content.

There are limits. Advertisers do not get access to your Gmail, Drive or Photos information, nor to identifying details like your name or email address, and Google says it will not target ads on sensitive categories such as race, religion, sexual orientation or health.

If that trade-off does not appeal, you can disconnect individual apps from Search's Personal Intelligence features, or switch off Personalised Recommendations entirely, via the Search Services Personalisation settings page.
