Google’s Updated Privacy Policy Opens Gmail to Ad Personalization

On October 16, 2026, Google revised its privacy policy, removing a clear prohibition that had previously barred the use of Gmail, Drive, and Photos data for ad personalization. The new wording now allows such data to inform ads when it is shared with other Google services. This change coincides with the launch of Personal Intelligence, a 2026 feature that lets users feed data from multiple apps into Google AI products to improve responses. While the policy’s intent is to enhance AI performance, it also creates a pathway for Gmail content to be used in targeted advertising. The update was first noted by Android Authority, and it signals a shift in how Google may monetize sensitive user data. Users who previously relied on the policy’s guarantee of no ad personalization from Gmail may now see ads that reflect their email content.
