Google links personal files to ad targeting for AI Mode users

Users who connect their personal files to Google's AI tools now face a new layer of ad personalization. The tech giant updated its privacy terms to permit advertising based on the contents of Gmail, Drive, and Google Photos for individuals who opt into this data sharing.

The revision modifies a long-standing promise that Google would not use data from these specific services for personalized ads. Since October 16, the policy includes a new exception. It states that the company will not use the data unless the user explicitly makes it available to other Google services that support personalized advertising.

This change primarily affects people who use the Personal Intelligence feature. By connecting their accounts to AI Mode and other Search tools, users allow these tools to analyze their content to provide tailored answers. Under the new rules, that same connection means the content can also be used to target ads. The policy text notes that Search or Gemini Apps may process permitted data to personalize content, including advertisements.

Google has outlined specific limits to the practice. Advertisers do not receive direct access to the files in a user's Drive, Gmail, or Photos. They also do not receive personally identifying information such as names or email addresses. The company stated it will not show ads based on sensitive categories, which include race, sexual orientation, religion, and health.

The update clarifies how ad personalization works across the ecosystem. The policy explains that depending on user settings, Google may show ads based on interests, activity, or personalized content from various services. For example, a user who searches for mountain bikes in Search might later see ads for sports equipment on YouTube.

Individuals who wish to exclude their personal data from ad targeting have two main options. They can disconnect specific apps from Search's Personal Intelligence features. Alternatively, they can switch off Personalized Recommendations entirely through the Search Services Personalization settings page.
