Google Lets Opted-In Gmail Data Shape Ads

Google has changed its privacy policy so that content from Gmail, Google Drive and Google Photos can help personalize ads — but only for people who choose to connect those apps to services such as Search. The revised policy took effect Oct. 16, 2026, and the change was reported by 9to5Google on Oct. 23.

Key takeaways

• Google's privacy policy dated Oct. 16 adds an exception to its long-standing promise not to personalize ads using content from Drive, Gmail or Photos.
• The exception applies when users make that data available to Google services that support personalized ads, such as Search through Personal Intelligence.
• Google still says it does not share information that personally identifies users, such as a name or email address, with advertisers unless they ask it to.

What changed in Google's privacy policy

The version of the policy in force from Oct. 1 stated plainly: "We don't show you personalized ads based on your content from Drive, Gmail, or Photos." There was no exception attached.

The current Google Privacy Policy keeps that sentence but extends it. Google now says it won't use that content for personalized ads "unless you choose to make data from these services available to other Google services that support personalized ads." A new line adds: "For example, Search may process some of the data that you allow Search to access to personalize content, including ads."

The policy's definition of personalized content now names Personal Intelligence directly. A sentence promising that Google does not hand advertisers a user's name or email "unless you ask us to" was not changed.

How Personal Intelligence connects Gmail and Photos

Personal Intelligence lets Google's AI tools read a user's own content to give tailored answers. It launched in beta on Jan. 14, 2026, for paying AI Pro and AI Ultra subscribers in the U.S., according to 9to5Google and PPC Land. On March 17, Google said in a company blog post that the feature was available in AI Mode for U.S. users and rolling out to free users of the Gemini app and Gemini in Chrome.

The feature is off by default. "You choose if and when you want to connect apps like Gmail and Google Photos," Google wrote in March. It works only with personal accounts.

A Google Search Help page lists Gmail, Google Calendar and Google Photos as the apps that can currently be connected, and requires users to be 18 or older. One connection covers what Google calls Search services: Search, including AI Mode and Discover, plus Maps, Shopping, Flights, Hotels, Translate and News.

What the data can be used for

The help page says Google uses "summaries, excerpts, generated media, and inferences" drawn from connected emails, files and photos, and trains its generative AI models on that material, though not "directly" on a user's Gmail inbox. A subset of AI Mode and Ask Maps data is reviewed by human reviewers.

Disconnecting an app does not delete data already in a user's Search Services History, which can still be used for model training, the page says. That history can be deleted at activity.google.com.

Context: a reversal of a 2017 promise

The update cuts against a commitment Google has repeated for years. On June 23, 2017, Google Cloud chief Diane Greene wrote that "consumer Gmail content will not be used or scanned for any ads personalization." The explicit Drive, Gmail and Photos line was added to the privacy policy on July 1, 2021, according to a review of policy archives by PPC Land.

The new wording ties ad personalization to an opt-in AI feature rather than to scanning every inbox. AI Newsway could not find a Google blog post announcing the change.

What's next

The practical impact depends on how many people connect their apps and how Google places ads in AI Mode and other Search services. A key question is whether Google's opt-in screens make the advertising use clear before users connect their inboxes.

FAQ

Will Google read my Gmail to target ads if I do nothing?

No. Under the policy, the exception applies only if you choose to make Gmail, Drive or Photos data available to Google services that support personalized ads, such as Search through Personal Intelligence.

Do advertisers see my emails or photos?

Google's policy says it does not share information that personally identifies you, such as your name or email address, with advertisers unless you ask it to.

How do I stop it?

Keep Personal Intelligence off or disconnect your apps. Data already in Search Services History stays until you delete it at activity.google.com.
