Google Just Changed a Promise It Kept for Nearly a Decade

Google rewrote a line in its privacy policy on October 16. Not a big rewrite.

The old promise was simple: we don't use your Gmail, Drive, or Photos to personalize ads. Full stop.

The new version keeps that sentence and tacks on an exception. Unless you choose to make data from these services available to other Google services that show ads. Which, if you've turned on Personal Intelligence in Search or Gemini, you just did.

This matters because Personal Intelligence isn't some fringe feature anymore.

Google's AI search can now read your connected apps through Personal Intelligence, an opt-in tool. Windproof. Your brand. The vibe you're going for. It's useful.

Here's the thing: as of October 16, Google's privacy policy no longer blanket-excludes Gmail, Drive, and Google Photos content from personalized advertising when users turn on Personal Intelligence.

Ads can now use summaries, excerpts, and inferences pulled from those apps to figure out what you might want to buy. Not the raw email itself—Google maintains advertisers never see your actual inbox or photo library. But the AI's understanding of what's in there. Your shopping habits. The brands you prefer. Where you travel.

Most consultants get this wrong, including us sometimes.

The tricky part isn't what Google announced. It's what it didn't announce for advertisers. If you manage a Performance Max campaign or a Shopping campaign on Google Ads, you won't find a new targeting option. No "reach people who connected their Gmail" toggle. No reporting dashboard showing you which Personal Intelligence users saw your ads. Nothing.

Advertisers cannot access user names, email addresses, Gmail inboxes, or Photos libraries directly. That part is real. But the inferences—the AI's educated guesses about you—those feed into auction eligibility and ranking. Quietly. Without any reporting layer.

So the math looks like this: you enable Personal Intelligence. Google uses your data to understand you better. That understanding shapes which ads you see. But you and the advertiser never get told it's happening.

Google did include safeguards, to be fair. Sensitive categories including race, religion, sexual orientation, and health remain excluded from personalized ad targeting. You can turn this off by disconnecting the apps in your Google Account settings—though turning off ad personalization itself doesn't necessarily disconnect them from AI features.

It's the right move.

But it's also a masterclass in writing policy language that technically keeps the old promise while breaking the spirit of it. Google didn't lie. It just found the exception to its own rule.
