Google updated its privacy policy on October 16 to permit using data from Gmail and Google Photos for targeted ads when users enable Personal Intelligence features. The change adds an exception to Google's longstanding promise not to use sensitive app data for ad personalization, affecting users who connect these services to AI Mode and Gemini for enhanced recommendations.

Google Privacy Policy Quietly Opens New Ad Targeting Pathway

Google privacy policy changes effective October 16 have introduced a significant exception to the company's longstanding data protection promise. The updated policy now permits using Gmail data and Google Photos data for targeted ads when users enable the Personal Intelligence feature

. The previous policy stated clearly: "We don't show you personalized ads based on your content from Drive, Gmail, or Photos." That protection remains, but with a critical qualifier: "unless you choose to make data from these services available to other Google services that support personalized ads"

This shift matters because it dismantles a firewall that separated sensitive personal information from Google's advertising operations. For years, users trusted that flight bookings, receipts, and family photos stored in these services wouldn't influence the advertisements they encountered

4

. That assurance now comes with conditions tied directly to AI-driven personalization features.

Personal Intelligence Feature Creates Data Sharing Pathway

The Personal Intelligence feature, launched in January 2026 for paying subscribers before expanding to all US users in March, sits at the center of this privacy shift

. This opt-in capability allows Gemini and AI features in Search to access data from multiple Google services simultaneously. When someone asks AI Mode about restaurant recommendations near their hotel, the system can pull reservation details from Gmail and suggest nearby options based on previous vacation photos

Google positions this cross-service data access as essential for delivering relevant AI answers. The company views its wealth of user data as a competitive advantage in AI development

1

. However, connecting apps to enable these AI features creates a pathway for personal information to inform ad personalization. When users interact with AI Mode while Personal Intelligence is enabled, summaries and insights from Gmail or Google Photos that inform AI responses can simultaneously contribute to ad targeting

1

.

Google emphasizes that ads won't be "based directly" on Gmail inboxes or Photos libraries, and sensitive categories like health, religion, race, sexual orientation remain off-limits for ad targeting

3

. Advertisers don't receive access to these apps or personally identifying details such as names or email addresses

2

. Yet the distinction between using information to answer questions versus using it to select advertisements represents a meaningful privacy boundary that many users may not have anticipated crossing.

User Privacy Concerns and Control Settings

Google maintains that Personal Intelligence remains entirely opt-in, but user privacy concerns center on how the company presents this choice

1

. Various prompts and pop-ups encourage users to enable the feature without fully explaining the advertising implications. Many may have activated it without realizing the data usage consequences

1

.

Users who want to opt out have several options through user control settings. The most direct approach involves accessing Gemini settings for Personal Intelligence and disabling connected apps. Alternatively, navigate to Data & privacy > Personalization settings > Manage Personalized Recommendations in Search Services > Connected Content Apps within your Google Account settings

1

. From there, disconnect Gmail, Google Photos, or Google Drive individually

2

.

Disabling Personalized Recommendations entirely through the Search Services Personalization page provides another option

. However, disconnecting apps doesn't necessarily erase information Google has already saved. Data stored in Search Services History may persist even after disconnecting apps or deleting original emails and photos

Broader Implications for AI Model Training and Data Practices

This privacy policy update reflects a broader pattern in how Google handles data across its AI ecosystem. Similar exceptions exist in AI model training practices. While Google states it doesn't use personal data for AI model training, it does use user inputs and model outputs for that purpose

1

. With Gemini integrated across multiple services and connected through Personal Intelligence, those outputs may contain elements of personal information. Google attempts to filter such content from training sets but doesn't guarantee complete success

1

.

Google has also begun testing ads in AI Mode for users with Personal Intelligence enabled. In March, the company indicated this experience would remain ad-free initially, though it expected ads to function similarly for connected users eventually

4

. AI Overviews and other AI features in Search may display sponsored content, creating additional touchpoints where personal data could influence ad personalization

This marks the first time since 2017 that Google's policy has allowed inbox content to play a role in advertising, even indirectly

4

. Google previously scanned free Gmail accounts to target ads, a practice that drew lawsuits and criticism from privacy advocates before ending in 2017

4

. Gmail continued showing ads targeted using other data like search and YouTube activity, but inbox content itself remained protected until this policy revision.

Watch for how other AI companies navigate similar territory. OpenAI began showing ads to logged-in adult US users in January 2026 and has since expanded advertising to 89 countries across Latin America, Europe, Africa, and Asia

3

. OpenAI emphasizes that user data and conversations remain protected and never sold to advertisers, and that ads don't influence chatbot responses

3

. As AI services mature, expect continued tension between personalization benefits and privacy protection, with companies testing where users draw acceptable boundaries for data usage in exchange for enhanced AI capabilities.
