The sentence that changed

For years the sentence did specific work. Google stopped scanning free Gmail accounts' message content to select ads in June 2017, and the flat policy line that followed, no personalized ads based on your content from Drive, Gmail or Photos, became the answer the company could point to. It appeared without qualification in the version this one replaced.

The new version does not delete the sentence. It appends a condition to it, and adds a paragraph above it explaining that you may let Search or the Gemini apps access data from Photos and from Workspace apps, and that Search may process data you allow it to access "to personalize content, including ads". The definition of personalized ads was widened in the same edit, from your interests and activity to your interests, activity, or "personalized content" from Google services.

The policy change was not itself a product-launch announcement. Separate reporting in October described testing of ads in AI Mode for users who had connected apps through Personal Intelligence; the scope of that testing and the use of connected-content inferences in ad selection remain distinct questions. What changed is the ceiling on what Google may do with data a user has already handed to its AI features, and it changed in a policy update that Google did not announce in a blog post. The update sat largely unnoticed for a week, until Android Authority read the redline on October 23.

How an email reaches the ad system

Google's own description is narrower than the headline version, and the narrowing matters. Nobody at Google claims the ad system scans your inbox. The route runs through Search.

A user turns on Personalized Recommendations in Search and connects content apps: Google Workspace, which in practice means Gmail and, in the US in English, Calendar, and Google Photos where offered. When that user asks AI Mode a question, Search can pull the relevant email or photo, a booking, a receipt, and summarize it into the answer. The help page says those summaries, excerpts and inferences become part of Search Services History, and that the same information may be used to show ads.

So the object that can reach ad selection is not the email. It is what Search concluded from the email while answering you: that you have a trip coming up, a purchase pattern, a reservation in a particular city. Google's systems have always chosen ads from inferences about activity. What is new is that inferences drawn from the content of your mail and photos are now inside the set the policy allows, for users who connected those apps.

Two consequences follow that the announcement coverage mostly skipped. First, the same summaries and inferences can be used to train generative AI models, and a subset goes to human reviewers. Notebookcheck reports that Google's help page notes that, for a short or particularly relevant email, the summary may be the email itself. Second, the record is sticky. Google's Personal Intelligence help guidance, as quoted in reporting, distinguishes disconnecting a content app from deleting Search Services History: disconnecting changes access to the connected source, but it does not, by itself, clear the summaries and inferences already saved in Search Services History, and deleting the original email does not either. Users who want that history gone have to manage it separately, through My Activity.

Permission is not the same as practice, yet

Google's policy and its statements about current practice need to be kept separate. The policy effective October 16 permits connected content to be used by services that support personalized ads. Separately, Search Engine Land reported that Google had begun testing ads in AI Mode for users who connected their apps through Personal Intelligence. Fast Company had previously reported Google's statement that using Personal Intelligence to target ads elsewhere in Search was "not the case today." These reports do not establish a complete account of which ads are currently informed by connected-content summaries or inferences. Google has not publicly reconciled those statements in the material reviewed here.

That gap is the reason to read the policy text rather than the reassurance. The policy establishes what Google says it may do under the stated conditions. It does not, on its own, establish how broadly that permission is being exercised today or whether its scope will expand. Those questions require further statements or evidence about implementation.

What did not change

Three limits survived the edit, and they are worth stating because the coverage at both extremes tends to drop them.

If you have not chosen to make Drive, Gmail or Google Photos data available to another Google service that supports personalized ads, the new exception does not describe a permission you have exercised. The original exclusion remains, subject to the policy's wording and your actual account settings.

Advertisers still get no access to your inbox or library, and the policy still says Google does not share information that personally identifies you with advertisers unless you ask it to. Advertisers choose audiences; Google decides who is in them.

Sensitive categories remain excluded. The policy continues to bar personalized ads based on race, religion, sexual orientation or health. What it does not explain is how inferences drawn from an inbox are screened against those categories in practice, which is a fair question to leave open rather than answer on Google's behalf.

According to The Hacker News' account of the rollout, Personal Intelligence is opt-in, limited to eligible users aged 18 and over, and was offered in supported markets with the European Economic Area, Switzerland, the UK and Nigeria excluded. These availability details describe the reported rollout, not a universal rule that the feature is unavailable throughout Europe under every Google product or configuration.

If you connected the apps and want out

How to check the settings: The following route was documented in October 2026 reporting. Google is updating its Search Services settings, so menu names or locations may differ by account and rollout.

Disconnecting is a two-step job, and the second step is the one that matters.

First, disconnect. In your Google Account, go to Data & privacy, then Personalization settings, and open Manage Personalized Recommendations in Search Services. Under Connected Content apps, disconnect Google Workspace and Google Photos, or turn Personalized Recommendations off entirely. The Gemini app has its own connection settings.

Then delete what Search kept. Go to My Activity and clear your Search Services History. Until you do, the summaries and inferences drawn from your mail and photos remain stored and, under the help page's terms, usable for the purposes described there, including model training. Turning off personalized ads in My Ad Center is a separate control: it limits ad targeting, but it does not disconnect the apps or delete the history.

People who connected Gmail in January or March did so under the previous wording. Google has not said whether it will notify them that the terms attached to that connection changed in October, or ask them to confirm. If you connected early, assume the new text is the one that governs you now, because that is how policy updates work, and decide accordingly.
