MOUNTAIN VIEW, October 23, 2026 — Google has updated its privacy policy to allow data from Gmail, Google Photos, and Drive to shape personalized advertisements, provided that users explicitly opt in to cross-service access for tools like Search and Gemini Apps. The change alters a foundational privacy promise that the company had maintained in identical wording since July 2021.
The Policy Shift Under the Hood
The technical reality of the update rests on a new exception added to Google’s privacy policy, which took effect on October 16, 2026, replacing a version that had been in force since October 1, according to policy archives. For more than five years, a specific bullet point in the policy stated that personalized ads would not be shown based on content from Drive, Gmail, or Photos. The October 16 revision retains that baseline rule but appends a crucial qualification.
The revised text now states that Google does not show personalized ads based on content from those services “unless you choose to make data from these services available to other Google services that support personalized ads,” according to the company policy. As ever, the detail that matters lies in the mechanics of how data moves between products. A new passage explains that users may permit services such as Search or Gemini Apps to access data from Workspace applications and Google Photos to secure a more personalized experience, subject to the policies of the accessing service.
Personal Intelligence and Data Flow
The updated policy ties these advertising mechanisms directly to Personal Intelligence, an opt-in feature that lets AI tools draw on emails, photos, and files, as reported by The Verge. Additional context added to the policy explains that if users allow specific services to process data for features like Personal Intelligence, that same information may be used to personalize their overall experience.
For example, if a user asks Search a question about a recent hotel booking, the system may use details extracted from an email to suggest activities near the destination, according to the policy notes. Furthermore, the policy states that Search may process allowed data to personalize content, including advertisements. A revised example in the policy specifies that searching for mountain bikes in Search could lead to sports equipment advertisements on YouTube, depending on user settings and permissions.
Google Official Clarifications and In-Car Rollout
In response to public discussion, a Google spokesperson told Ars Technica that connecting applications is entirely opt-in and emphasized that advertisements will not be based directly on a user’s Gmail inbox or Photos library. The company also confirmed that sensitive information will not be used to tailor ads.
The Personal Intelligence feature driving these data flows is expanding beyond web and mobile interfaces. According to Google’s Android blog, Personal Intelligence is rolling out for Gemini on Android Auto and will reach vehicles running Google built-in in the coming months. The company stated on its official X account that the feature securely connects information from Google apps like Gmail, Calendar, and Search with user permission to provide hands-free assistance on the road.
Housekeeping Edits and Data Source Expansion
Beyond the primary advertising exception, the October 16 revision included minor technical adjustments to the policy text. In the section regarding managing user information, the phrase “Photos and Drive” was updated to “Google Photos and Drive.” Additionally, two “Learn more” links were removed from the Additional Context entries labeled “deliver our services” and “show trends,” according to the policy redline.
The scope of data accessible to Gemini through Personal Intelligence has also expanded beyond the core office suite. While the initial rollout focused on Gmail, Calendar, and Search, the feature now draws from Google Photos, Google Maps, and YouTube when a driver grants permission. This broader access allows the system to retrieve details from past conversations and provide personalized recommendations based on a wider array of user interactions.
