Google has quietly carved out an exception to one of its longest-running privacy commitments, rewriting the rules that have governed its most personal products for years. A revision to the company's privacy policy, effective Oct. 16, allows content from Gmail, Drive, and Google Photos to help personalize ads when users connect those services to Google's AI features—a shift that ties advertising to the company's expanding AI ecosystem. The update went largely unannounced; tech outlet Android Authority was first to spot it.

The updated policy, published on Google's official privacy page, now states that 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.” Previously, the policy contained no such exception; the new conditional clause describes the route around the long-standing protection. The stakes of that wording are sizable: advertising has long generated the majority of Alphabet's revenue, which is why even narrow changes to Google's ad rules ripple across an ecosystem used by billions of people.

The exception hinges on Personal Intelligence, Google's push to make its AI tools more useful by letting features such as AI Mode in Search and Gemini draw on a user's own data. Connecting Gmail, Drive, or Photos to those tools delivers more tailored answers—for instance, surfacing a hotel reservation buried in an inbox. Under the revised wording, however, the same connected data can now also inform which ads a person sees, though the connection is off by default and advertisers do not see the underlying content. The structure reflects a broader industry pattern in which AI assistants grow more capable by plugging into personal data stores: each new link between services creates another channel for information to flow, and Google's revision makes a single consent decision govern both smarter answers and ad personalization.

Google stressed the limits of the new arrangement. Content from the three services is still not used for ad targeting by default, advertisers do not get access to the contents of anyone's Gmail, Drive, or Photos, and the company says it will not share personally identifying details without permission. In practice, that means Google is not wholesale scanning private emails and photos to sell advertising. But the revision opens a pathway: users who opt into its AI conveniences may be trading some ad privacy for the added utility.

Opting out remains possible, though not always fully retroactive. Users can disconnect the apps under Connected Content apps in their Google Account's Data & privacy settings, or turn off personalized recommendations entirely. Even then, Android Authority noted, previously collected data may linger in a user's Search history after the apps are disconnected. With the revised policy already in effect, those settings are now the operative control point for anyone who has linked Gmail, Drive, or Photos to Gemini or AI Mode in Search.

The quiet rollout of the change echoes recent Google privacy posturing around its AI ambitions. As Decrypt reported in May, Google's Chrome browser began silently installing a multi-gigabyte on-device AI model on users' computers, and separately removed a privacy claim tied to its Gemini Nano model. Both moves drew scrutiny over how the company handles user data as it races to embed AI across its products.
