Google’s Personal Intelligence Opens Gmail and Photos Data to Search Ad Targeting

Google’s Personal Intelligence setting now has a clearer advertising consequence: data shared from services such as Gmail, Drive and Photos with Search or Gemini may inform personalized ads. The updated policy took effect October 16, changing how Google describes the boundary between private service content and ad targeting. For users, the change is less about a newly announced ad product than a newly explicit connection between cross-service access and advertising.

That distinction deserves attention. People may understand that linking services lets an AI assistant tailor answers, but not assume that the same permission can affect ads. Google’s revised wording makes that possibility harder to miss, though users still need to understand which settings control it.

What the policy change says

Google previously said personalized ads weren’t “based on your content from Drive, Gmail, or Photos.” The new wording keeps that statement but adds an exception: “unless you choose to make data from these services available to other Google services that support personalized ads.” The update was first reported by Android Authority, via The Verge, and appears in Google’s updated privacy policy.

The wording draws a line between content kept within one service and data a user permits another service to access. That line now has an advertising dimension. The policy doesn’t say every piece of shared information will affect every ad; it says data made available to a service that supports personalized ads may be used for that purpose.

That exception connects to Personal Intelligence, Google’s account-level feature that lets Gemini draw on information across services including Gmail, Photos, Search and Drive. It began rolling out in beta earlier this year. Google’s policy says services such as Search or Gemini Apps may access data from other Google services to personalize the experience; Search, for example, may use permitted data to personalize content, including ads.

Here’s the thing: “personalization” can describe several different outcomes, from more relevant answers to advertising choices. A user might approve access for one reason and not realize the same data sharing could have another effect. The policy update clarifies the relationship, but the setting itself still asks users to weigh those uses together.

Content access and ad targeting

The distinction matters. Google hasn’t said advertisers can directly browse users’ inboxes, cloud files or photo libraries. Instead, the policy allows a service that receives access to that data to use it for ad personalization. In practice, information connected through Personal Intelligence could shape ads shown in Search.

That’s a meaningful difference in how the process works, but it may not feel like one to a user who sees an ad informed by information from a private service. The policy describes data moving between Google services under user-granted access; it doesn’t describe advertisers receiving the underlying messages, files or photos themselves.

Google’s existing statement that advertisers don’t receive identifying details such as a person’s name or email address without permission remains unchanged. Still, the policy makes the implications of linking services more consequential: enabling cross-service personalization can affect advertising, not just the answers or recommendations a user sees.

This is more significant than it looks because a permission can carry consequences beyond the feature that prompts a user to enable it. The details matter: which service receives access, what it can do with the data, and whether ad personalization is among those uses. (And this is the part most people overlook.) A privacy policy can explain the boundary, but users still have to find and interpret the controls that apply to their account.

Reviewing account settings

Personal Intelligence is opt-in. Users who want to check how Search handles recommendations can visit My Account, open Data & privacy, then Personalization settings, and choose Manage Personalized Recommendations in Search services. The page also offers a control to turn Personalized Recommendations off.

If you're working across Google services, review the access choices before connecting Gmail, Photos or Drive. Check what the receiving service can use and whether you’re comfortable with that data potentially informing ads as well as answers or recommendations. Turning off Personalized Recommendations is another option identified on the settings page.

What the change means for users

The policy update puts a practical question in front of users: is the convenience of cross-service personalization worth allowing information from one service to influence experiences elsewhere? The answer depends on personal preferences, but the trade-off is now more clearly stated. A setting that sounds focused on Gemini or Search may also have relevance to advertising.

That said, the available details don’t establish how often this data would affect a particular ad or which kinds of shared information would shape a specific result. The policy describes permission and potential use, not a guaranteed outcome for every user. For anyone uneasy about that uncertainty, reviewing the account controls is the clearest step available from the information provided.

One thing is clear: cross-service access has broader implications than tailored responses alone. Worth a closer look.
