AI Personalization: Google's Policy Shift on Data Use

Google has modified its privacy policy to permit the use of data from services like Gmail, Drive, and Google Photos for targeted advertising in specific circumstances. This change, which was implemented on October 16th, 2026, could result in users seeing advertisements tailored to the content within those services if they have enabled personalized AI features.

The update introduces an exception to the company's previous commitment that data from these services would not be used for personalized ads. The new policy language states that data from Gmail, Drive, and Google Photos will not be used for ads 'unless you choose to make data from these services available to other Google services that support personalized ads.'

This adjustment is directly linked to the activation of features like Personal Intelligence for Search and other tools, which allows these services to access user data from Drive, Gmail, or Google Photos. The purpose of this connection is to provide more tailored responses and recommendations by understanding more about the user's context and information.

According to the updated terms, granting access to this data for improved AI-powered recommendations also opens it up for the purpose of showing personalized advertisements. The policy explicitly notes that a user's permission for a service like Search to access data from other Google services can be used for this purpose, stating, 'Search may process some of the data that you allow Search to access to personalize content, including ads.'

However, the policy outlines specific limitations on how this data can be used. Advertisers do not receive direct access to the content within a user's Gmail, Drive, or Photos, nor do they receive personally identifying details. Furthermore, Google has stated it will not use this information to target ads based on sensitive categories such as race, sexual orientation, religion, or health.

The policy also provides a specific example of how this targeting might manifest, explaining that if a user searches for 'mountain bikes,' they may see ads for sports equipment on YouTube. This illustrates how a user's activity or interests, potentially derived from their personal data, can influence the advertising they are shown across Google's ecosystem.

For users who wish to prevent their personal data from being used for targeted ads, there are controls available. Individuals can choose to disconnect specific applications from Search’s Personal Intelligence features or disable Personalized Recommendations entirely through the Search Services Personalization settings page.

The immediate consequence of this policy change is that users who have opted into advanced AI personalization features may now encounter advertisements based on the contents of their personal files and communications. The availability of settings to disable this functionality means users retain control over whether their data is used for this purpose.

The next step for users concerned about this change is to review their personalization settings to understand how their data is being used and to adjust their preferences if necessary. The policy update clarifies the terms under which Google can use personal data for advertising when users engage with its more advanced, personalized AI services.
