Google Policy Change Lets Gmail and Photos Data Shape Your Ads

Since 2017, Google has told Gmail users that their messages stay out of ad targeting. On October 16, 2026, it kept the sentence in its privacy policy that says so and attached a condition: connecting Gmail and Google Photos to Personal Intelligence, the feature that lets AI Mode and Gemini answer questions using your own data.

Key Takeaways

• Google's privacy policy, effective October 16, 2026, added an exception to its rule against personalizing ads with Drive, Gmail or Google Photos content.
• The sentence grew from 15 words to 34, and the choice it refers to is connecting Gmail and Google Photos to Personal Intelligence in Search services such as AI Mode.
• Google's Search help page says ads "will not be based directly" on your inbox, but summaries, excerpts and inferences drawn from it "may be used to show you ads."
• Google added an update dated October 16, 2026 to its June 2017 Gmail blog post, saying connected Workspace data "can also be used to show ads" depending on your settings.
• Disconnecting the apps doesn't delete data already saved in Search Services History, and Google does not say whether that retained data keeps shaping ads.

What Exactly Changed in Google's Privacy Policy?

Google rewrote its ads promise for Drive, Gmail and Photos and added passages that tie connected app data to ads. The version effective October 12, 2026 read:

"We don't show you personalized ads based on your content from Drive, Gmail, or Photos."

The current policy, effective October 16, reads:

"We don't show you personalized ads based on your content from Drive, Gmail, or Google Photos, unless you choose to make data from these services available to other Google services that support personalized ads."

The old promise was 15 words long. The new sentence is 34: "Google" now sits in front of Photos, and an "unless" clause of 18 words follows. The exception is longer than the promise it qualifies.

Google's own comparison page shows more edits in the same release:

• A new paragraph says "Search may process some of the data that you allow Search to access to personalize content, including ads."
• Ads are now described as based on "your interests, activity, or personalized content from Google services," where the earlier text said "interests and activity across Google services."
• A third addition names the feature outright: data shared "for features such as Personal Intelligence" may personalize your experience, with the example of Search reading hotel booking details from an email.

Why Is Personal Intelligence the Trigger?

Personal Intelligence is the switch that makes your Gmail and Photos data "available to other Google services." We covered its January launch in Gemini in our explainer on Gemini reading your Gmail. The ads question sits on the Search side.

Google's Search help page on connecting content apps says connecting means "all Search services will be permitted to access Workspace (currently Gmail and Google Calendar) and Google Photos," including AI Mode, Discover and Maps. Its FAQ on ads:

"Ads will not be based directly on your Gmail inbox or your Google Photos library. If you connect your content apps to Search Services, Search may reference summaries, excerpts and inferences from these sources to personalize your experience and do things for you. That same info may be used to show you ads, so they are even more helpful for you."

What Has Google Said?

Google says the change is opt in and that ads won't come "directly" from your inbox. Its full statement to Ars Technica on October 23:

"Connecting your apps is entirely opt-in. Ads will continue to be relevant to things like your query, the context of the response and your interests. Ads will not be based directly on your Gmail inbox or Photos library, and as always, sensitive information will not be used to tailor ads."

Ars notes the Gemini app "does not currently have ads," while AI search tools can show sponsored content. The help page says advertisers "will not have access to your Gmail inbox or Google Photos." Android Authority, which spotted the change first, adds that it "doesn't mean Google automatically scans your private emails and photos to serve ads."

The weight sits on the word "directly." A summary of your flight confirmation isn't your inbox, but it carries the same facts. In its section on AI training, the same help page concedes that for a brief or particularly relevant email, "the summary may just be the email or file." Google doesn't say whether that holds for ad signals.

A 2017 Promise Now Carries a Footnote

In June 2017, Google Cloud CEO Diane Greene wrote in a Google blog post that "Consumer Gmail content will not be used or scanned for any ads personalization after this change." That post now carries a bracketed update dated October 16, 2026:

"If users choose to enable these new features, data from Workspace Apps will be processed to personalize other Google experiences, and depending on a user's settings, that same subset of data can also be used to show ads."

Google's How Gmail ads work page now carries the same qualifier: Google doesn't use Gmail content for ads "unless you choose to make data from these services available to other Google services that support ads." The exception now appears on at least three Google pages.

On July 28, Google spokesperson Allie Bodack told Fast Company that using Personal Intelligence to target ads elsewhere was "not the case today." Eighty days later, the policy allows it. A promise that held for more than nine years now has an opt in exception; the backstory is in our piece on what Google scans in Gmail.

Does Turning Off Personal Intelligence Undo It?

Google documents how to stop sharing new data, but not what happens to ad signals already built from it. 9to5Google wrote that "you can't opt out with disabling Personal Intelligence," yet the same article says the feature "remains opt-in" and lists steps to turn it off. Ars Technica and Android Authority both point to disconnecting the apps as the way out.

Here is what Google's own text supports:

• Documented: the exception applies only "unless you choose" to share, and the help page says you can disconnect content apps "at any time."
• Documented: "Disconnecting a connected Google content app or deleting any data in that app doesn't delete any data from your Search Services History. That data can still be used for product improvement, including training generative AI models."
• Not documented: whether summaries or inferences already saved keep influencing ads after you disconnect.
• Documented backstop: per My Ad Center Help, when you turn off personalized ads, Google "will not use the information and activity saved to your Google account" to show you ads.

What This Means for Your Inbox

Your inbox is probably the most detailed record of your life that Google holds: receipts, bookings, bank alerts. Until October 16, Google's policy kept it out of ads without conditions. It follows a July announcement that Google would use the IP address from Gmail sessions for ad targeting in the UK and EU. That change concerned metadata. This one reaches inferences drawn from what your messages say.

Keep the layers apart. Google's ad personalization lives in your account settings, and no browser extension switches it off. The senders in your inbox run a separate surveillance layer: tracking pixels that report when and where you opened their email. That layer you can block yourself.

How Do You Check and Disconnect Your Settings?

Check Search and Gemini separately; each keeps its own connected apps list. Google warns on its AI Mode personalization page that Search settings are being updated, so labels may differ slightly.

1. Search: in your Google Account, open Search Services Personalization, then Additional Personal Intelligence, then Connected Content Apps. Disconnect Google Workspace and Google Photos.
2. Gemini: on gemini.google.com, click Settings & help, then Personal Intelligence, then Connected Apps, and turn off Google Workspace and Google Photos. Steps are on the Gemini Apps help page.
3. Turn off Personalized Recommendations on the Search Services Personalization page if you don't want AI Mode personalization at all. Google requires it to be on before apps can connect to Search.
4. Turn off personalized ads: go to myadcenter.google.com, select Off next to Personalized ads, and confirm.
5. Delete saved history: Google says you can manage and delete Search Services History at activity.google.com.

For compliance teams

Gemini's Personal Intelligence "isn't available when you sign in to a work, school, or supervised Google Account," and is "Not available in the European Economic Area, Nigeria, Switzerland, or the United Kingdom." The exposure sits with staff who handle work mail in a personal Gmail account, where connecting apps is the employee's own choice.
