Google’s privacy policy now says that if you let Search or Gemini read your Gmail, Photos or Drive, that data can help personalize Google Gmail ads. The change took effect on 16 October 2026, and it reverses a line Google had repeated for years.
The key word is “if”. Nothing changes unless you connect your apps, but plenty of people will, because the feature is useful.
Key takeaways
- The updated policy took effect on 16 October 2026, per The Hacker News.
- Google still says it does not personalize ads from Gmail, Drive or Photos content by default.
- The exception: data you allow Search or Gemini to access can be used to personalize content, including ads.
- Google has begun testing ads in AI Mode for people who connect apps through Personal Intelligence.
- You can disconnect apps or switch off personalization in your settings.
What exactly did Google change in its privacy policy?
The new text says you may allow certain Google services, such as Search or Gemini Apps, to access data from other Google services you use. As an example, it says Search may process some of that data “to personalize content, including ads.”
The older promise survives in part. Google still states that it does not show personalized ads based on your Drive, Gmail or Photos content. The new wording adds an exception for data you make available to services that support personalized ads, as Techlicious and The Hacker News describe it. Android Authority reported the change first.
How does Personal Intelligence connect to ads?
Personal Intelligence is a Gemini feature Google introduced in January 2026. You connect services such as Gmail, Google Photos and YouTube, and the AI uses them to give tailored answers. The same idea now reaches AI Mode in Search.
Google says it is a beta for eligible users over 18, available worldwide except the European Economic Area, Switzerland, the U.K. and Nigeria.
Here is the catch. Search Engine Roundtable reported on 19 October 2026 that Google confirmed ads in AI Mode for people with Personal Intelligence enabled. Per the reporting, Google says ads are not built directly from your inbox or photos. Summaries, excerpts and inferences drawn from them, however, may be used.
Is this a reversal of what Google promised?
Largely, yes. Reporting summarized by Fast Company notes that in March Google told reporters there were no ads for people who connected their apps to AI Mode. Fast Company’s Jared Newman called the lack of clarity for ordinary users unacceptable.
My opinion: the distinction between “your email” and “an inference from your email” is thin. If your inbox shows a flight booking and an ad for hotels follows, you will not care which side of the line it came from.
What is and isn’t used for ads?
| Situation | Used for ad personalization? |
|---|---|
| You never connect apps to Search or Gemini | No, per Google’s policy |
| You connect Gmail or Photos to AI Mode | Possibly, via summaries and inferences |
| Sensitive topics (race, religion, sexual orientation, health) | Google says ads are not personalized on these |
| Advertisers reading your connected apps | No, Google says advertisers get no access |
How do you opt out?
- Open Gemini’s Settings and go to Personal Intelligence, then disconnect any app you do not want linked.
- Visit google.com/search-personalization and switch off personalized recommendations in Search personalization settings.
- Use temporary chats or ask for non-personalized answers when you want a clean slate.
Google says Personal Intelligence is off by default, so most people start safe. Check it anyway if you ever tapped “connect” during setup.
Why does this matter beyond Google?
AI assistants earn trust by knowing you well, and advertising pays by knowing you well. Those goals collide. OpenAI began showing ads to logged-in adult U.S. users on its free and Go tiers in January 2026, so the whole industry is moving the same way. For another case of trust and AI assistants, see our piece on the WhatsApp help pages leak.
What happens next
Google has not said which markets the AI Mode ad test covers, which formats will appear, or what controls advertisers get, per Relevant Audience. Expect regulators and privacy groups to ask those questions, especially in regions where the feature is not yet available.
