Mountain View, Saturday, 24 October 2026.
Google’s revised privacy policy permits user data from Gmail and Photos to shape commercial advertisements, provided users opt into the company’s new personal artificial intelligence search features.

Policy Revision on October 16, 2026

Alphabet Inc. (NASDAQ: GOOGL) updated its privacy policy on October 16, 2026, to permit the use of personal data from Gmail, Google Photos, and Google Drive for ad targeting when users opt into the company’s new personal artificial intelligence (AI) search features, such as Personal Intelligence [1][2][5][8]. The change explicitly removes prior language that excluded data from these services from being used for personalized advertisements [2][8]. While Google has stated that ads will not be based directly on private content, the policy now allows data shared with AI tools like Search and Gemini to influence ad personalization [2][5][6].

Mechanism of Data Utilization

The revised policy enables Google’s AI-powered features to process data from connected services when users opt in. For instance, if a user enables Personal Intelligence and connects their Gmail and Photos, data such as email content or image metadata could inform AI search results, which may then be used to tailor advertisements [1][2][5]. Google has clarified that advertisers do not receive direct access to private data, and sensitive categories like race, sexual orientation, religion, or health are excluded from ad targeting [1][5][8]. However, the policy change has raised concerns about indirect data usage, where insights derived from AI processing could still shape ad relevance [2][6][9].

User Control and Opt-Out Mechanisms

Users retain the ability to opt out of data sharing for ad targeting. To prevent their data from being used, individuals can disconnect connected apps from Personal Intelligence or disable Personalized Recommendations entirely through their Google Account settings [1][3][5][8]. Disconnecting apps does not necessarily delete previously saved data, as some information may remain in Search Services History [3][8]. For example, users who disable connected content will still see ads relevant to their search queries and interests but not those directly influenced by private data [1][5].

Regulatory and Competitive Implications

The policy revision has drawn renewed scrutiny from regulators and privacy advocates, who question the expansion of ad targeting capabilities under the guise of AI personalization [1][2][6]. Google’s move aligns with its broader strategy to monetize its AI ecosystem, which competes directly with platforms like Meta, another dominant player in digital advertising [4]. Meta’s Muse AI agent app, launched in September 2026, has already achieved 109 million downloads, intensifying the rivalry between the two tech giants in the AI and ad markets [4]. Analysts from Bank of America note that Google’s proprietary AI models and product distribution give it a competitive edge in the AI era [4].

Public Reaction and Privacy Concerns

The policy change has sparked debates about user privacy, particularly regarding the indirect use of personal data in ad targeting. While Google maintains that content is not used for ads by default, critics argue that the line between AI-driven insights and ad personalization is increasingly blurred [2][5][6][9]. For instance, a user searching for restaurant recommendations after booking a hotel via Gmail could see ads influenced by their travel plans, even if their private emails are not directly scanned [1][3][5]. This nuance underscores the complexity of consent and data usage in the era of AI-driven services.
