Google privacy update raises Gmail ad questions for Gemini users

Google has updated its privacy policy in a way that raises new questions about how Gmail, Photos and other account data may intersect with ads in AI search. Ars Technica reports that the change matters most for people using Gemini with Personal Intelligence, Google’s opt-in system for connecting app data to AI features.

For creators, freelancers and small businesses, the issue is not abstract. If Gmail or Workspace content is part of how an AI answer is generated, Ars argues that it may also become part of the context around sponsored results in Google’s AI search tools.

What changed in Google’s privacy wording

According to Ars Technica, Google updated its privacy policy on October 16 in a change first spotted by Android Authority. The older ad personalization language included a more explicit promise that personalized ads would not be shown using content from Drive, Gmail or Photos.

The revised language is less direct, according to the report. Ars says the change appears to leave room for data from those apps to affect ad personalization when users choose to share that data with other Google services.

Google told Ars that the update is a clarification, not a change in how it handles data with advertising partners. A spokesperson also said Google is not scanning an entire inbox to build an ad profile and is not giving that information to third parties.

That distinction is important. The concern is not that Gmail suddenly becomes a direct ad-targeting feed by default. The concern is that connected AI features may use summaries, insights or responses derived from personal data, and ads in AI search may be influenced by that surrounding context.

Why Gemini Personal Intelligence is the key setting

The central product here is Google Gemini, specifically its connection to Personal Intelligence. Google released Personal Intelligence in early 2026, according to Ars, as a way for users to give Google’s AI products more context from multiple apps. The company’s pitch is that this added context can improve answers.

Ars reports that Personal Intelligence can connect user data to the Gemini app and to AI Mode search. The Gemini app itself does not currently show ads, according to the source, but Google’s AI search tools may display sponsored content.

That is where the privacy question becomes practical. If Personal Intelligence is turned on, AI Mode may use information derived from connected apps to produce responses. Ars argues that because ads can be tied to those AI search experiences, personal data can become one element in ad personalization, even if Google says ads are not based directly on the raw Gmail inbox or Photos library.

Google’s statement to Ars says connected apps are opt-in. The company also says ads will remain tied to things such as the search query, the context of the response and user interests, and that sensitive information will not be used to tailor ads.

What this means for work and marketing accounts

The practical takeaway for small teams is to treat Personal Intelligence as a data-sharing choice, not just an AI convenience feature.

If you use Gmail or Workspace for client conversations, campaign planning, customer support, invoices, proposals or media outreach, you should be careful about which Google services can draw on that content. The same applies to Photos if it contains product images, event material or client assets.

This is especially relevant for marketers who use Google search tools while researching campaigns. The source does not say that Google is exposing your private files to advertisers. But it does report that data routed into AI search through Personal Intelligence could affect the context used around ads.

For users who do not want this kind of connection, Ars says the simplest step is to turn off Personal Intelligence connected apps. The report points to two places to check:

• Gemini settings for Personal Intelligence, where connected apps can be disabled.
• Google Account settings under Data & privacy > Personalization settings > Manage Personalized Recommendations in Search Services > Connected Content Apps.

From that area, Ars says users can disable connections to Workspace and Google Photos.

For readers following the broader push to make Gemini work across more services, this also fits with Google’s wider emphasis on AI that can operate with app context; see our coverage of Google’s enterprise Gemini agent for work across apps.

The bigger privacy trade-off

Ars frames the issue as a personalization trap: Google’s AI products become more useful when they can draw on more personal context, but that same context creates more privacy risk when it moves between services.

The report also compares this to Google’s handling of AI interactions for model training. Ars says Google has stated that it does not use personal data for AI training, while also using user inputs and model outputs for training purposes. With Gemini connected to more services, Ars notes that outputs may contain pieces of personal information. Google says it tries to filter that content from user activity controls, but Ars says the company does not promise the filtering will always work.

For now, the safest reading is simple: if you do not want Gmail, Workspace or Photos context influencing AI search ad personalization, do not connect those apps through Personal Intelligence. If you do want the convenience, understand that Google’s updated policy language gives the company more room to use AI-derived context around ads than the older wording appeared to allow.
