For five years Google’s privacy policy carried a flat promise: no personalized ads based on what sits in your Drive, Gmail or Photos. The wording had not changed since July 1, 2021. A revision that took effect on October 16 keeps the promise and attaches a condition to it.
One clause, one exception
The policy bullet now says Google does not show personalized ads based on content from Drive, Gmail or Google Photos “unless you choose to make data from these services available to other Google services that support personalized ads.” The revision replaced a version that had been in force since October 1, according to Google’s policy archive.
The detail that matters is the plumbing described alongside it. The policy says users may let services such as Search or Gemini Apps reach data in Google Photos and Workspace apps like Gmail and Drive, in exchange for a more personalized experience, subject to the settings of the service doing the reading. A companion sentence says Search “may process some of the data that you allow Search to access to personalize content, including ads.” The long-standing example of a mountain bike search leading to sports-equipment ads on YouTube now specifies that the search happens in Search.
The Verge tied the change to Personal Intelligence, the opt-in feature that lets Google’s AI tools draw on a user’s emails, photos and files. A new explanatory note in the policy gives a hotel example: ask Search about a recent booking, and it may use details from an email to suggest things to do nearby.
Google’s line
A Google spokesperson told Ars Technica that “connecting your apps is entirely opt-in,” and that “ads will not be based directly on your Gmail inbox or Photos library.” Sensitive information, the spokesperson added, will not be used to tailor ads. As ever, the word to watch is “directly”: the policy itself says connected data may first be processed to personalize other experiences.
Nothing in the policy language confirms that Google reads every Gmail message to serve ads, and only Search is described as using the data that way. Gemini Apps is named as a service that can access it, but not tied to ads in the text.
The remaining October 16 edits are housekeeping. “Photos and Drive” became “Google Photos and Drive” in one section, and two “Learn more” links disappeared from the Additional Context entries for “deliver our services” and “show trends.”
Personal Intelligence goes in the car
The feature behind all this is spreading. Google said on October 20 that Personal Intelligence is rolling out for Gemini on Android Auto, with cars running Google built-in to follow in the coming months. With permission, it connects information from Gmail, Calendar and Search to give hands-free help on the road. Google says the feature is not on by default, and a driver who already enabled it in the Gemini app on a phone carries that choice over to the car.
