Google now lets connected Gmail and Photos data shape ads

Google has changed one sentence in its privacy policy that matters to anyone who connected Gmail, Google Photos or Drive to Google’s AI features. The policy, effective October 16, 2026, still says Google does not show personalized ads based on your content from Drive, Gmail or Google Photos, but it now ends that promise with an exception: “unless you choose to make data from these services available to other Google services that support personalized ads” [1][3]. In practice, the main way to make that choice is Personal Intelligence in Google Search, which lets AI Mode read insights from your email and photos to tailor its answers [2][4]. If you turned it on for better restaurant suggestions or trip planning, what Google infers from your inbox can now also shape the ads you see [2][5].

What was announced

Nothing was announced in a blog post. The change sits in the policy text, and The Verge reports it was first spotted by Android Authority [4]. Google’s own comparison view between the October 12 and October 16 versions shows the edit [3]. The earlier sentence ended after “Google Photos”, a flat promise not to use that content for personalized ads; the new one adds the “unless you choose” clause [3]. The same comparison shows a second edit in the ads paragraph: Google may now show you personalized ads based on your interests, activity, “or personalized content from Google services”, where the earlier text referred to interests and activity across Google services [3][4].

A third passage explains how the data gets there. The policy says you may choose to allow certain Google services, “including services like Search or Gemini Apps”, to access data from other Google services such as Google Photos, Gmail and Drive, subject to the policies and settings of the service doing the accessing [1]. It then gives one example: “Search may process some of the data that you allow Search to access to personalize content, including ads” [1].

Google’s help page for connected apps fills in the rest. You can connect Search services to Workspace, which currently means Gmail and Google Calendar, and to Google Photos [2]. Connecting to Calendar is only available in the US in English, and Photos is not available in all regions [2]. The feature is for users 18 and above [2]. Once you connect, the page says, all Search services may access those apps: Google Search including AI Mode and Discover, Maps including Ask Maps, Shopping, Flights, Hotels, Translate and News [2].

The help page now has a direct answer on ads [2][6]. It says ads will not be based directly on your Gmail inbox or Google Photos library [2]. But if you connect your apps, Search may reference summaries, excerpts and inferences from them to personalize your experience, and “that same info may be used to show you ads” [2]. Advertisers do not get access to your inbox or Photos, and Google says it does not personalize ads on sensitive categories such as race, religion, sexual orientation or health [2]. According to [4], advertisers also do not receive personal details such as your name or email address.

This reverses an earlier position. According to [6], Google said in March that there were no ads for people who connect their apps to AI Mode and that this was not changing “right now”, while expecting ads to arrive later. Google has now told Search Engine Land it is starting to test ads in AI Mode for users who connect their apps through Personal Intelligence, according to [6].

What changed, and for whom

The change does not touch people who never connected anything. Android Authority’s reading is that Gmail, Drive and Photos content is still not used for targeted ads by default, and that the exception only applies once you explicitly connect that data to a Google service with personalized ads [5]. Google is not scanning every inbox for ads; it is using what Search already learns from the apps you chose to connect [5].

It does touch anyone who switched Personal Intelligence on. That was a trade of privacy for better answers: AI Mode reads your reservations, purchases and photos so it can suggest a restaurant near a hotel you booked [2][5]. Under the new text, the same summaries and inferences can also decide which ads you see [2]. Android Authority puts the difference simply: using your information to answer a question is not the same as using it to choose ads, and people comfortable with the first may not be with the second [5].

There are other uses on the same help page that are easy to miss. If you connect your apps, Google says it may use that data to improve Google services for everyone, including by training generative AI models [2]. It does not train directly on your inbox or Photos library, but it trains on summaries, excerpts, generated media and inferences from them, and the page warns that when an email or file is short or especially relevant, “the summary may just be the email or file” [2]. A subset of that data is reviewed by human reviewers, including trained service providers, and Google asks you not to connect apps that hold information you would not want a reviewer to see [2].

Disconnecting is not a full reset. You can disconnect apps or turn off Personalized Recommendations from the Search Services Personalization page [4][5]. But disconnecting an app, or deleting data in it, does not delete anything from your Search Services History, and that data can still be used for product improvement, including training generative AI models [2]. You manage and delete that history separately, at activity.google.com [2]. Android Authority notes the same gap: data saved in Search Services History may remain after you disconnect or delete the original email or photo [5].

Gemini is the open question. The policy names “Search or Gemini Apps” as services you can let read your other Google data, but its ads example only names Search [1]. None of the sources we read says whether Gemini Apps uses connected Gmail or Photos data for ads, so for Gemini that is not public. Google also says it is updating the settings for Search services and that the settings described on the help page may not match what you see [2].

Who it is for — and not

This matters most to solo operators and small teams who run their business on a personal Google account. A single Gmail inbox in that setup often holds invoices, supplier threads and customer messages. If that inbox is connected, summaries of those messages can now feed ads, training data and human review [2].

It matters less if you never connected an app, if you use AI Mode without Personal Intelligence, or if Personal Intelligence is not available in your country or language [2][5]. The help page says connecting is optional, that AI Mode and Ask Maps still work if you do not connect, and that you can disconnect at any time [2].

It is not a reason to panic about ads on everything. Google still says advertisers do not get access to your inbox or Photos, and that sensitive categories are excluded [2]. The change is narrower and more specific: a feature sold as a way to get better answers now also serves Google’s ad business, and the policy text was changed to allow it [1][3]. Whether the trade is worth it depends on how much you use AI Mode with your own data, and how much of your work lives in that inbox.

This page will be updated if Google publishes an announcement, changes the help page again, or says whether Gemini Apps uses connected data for ads.

∴ Connecting Gmail or Photos to AI Mode now also feeds ads; disconnecting stops new access but not saved history.
