How to Turn Off Google Personal Intelligence: Stop Your Gmail and Photos Shaping Your Ads

For years, Google made a clear promise about your private content: "We don't show you personalized ads based on your content from Drive, Gmail, or Photos." On October 16, 2026, that promise quietly gained an exception — and if you have connected your Gmail or Photos to Google's AI features, summaries drawn from your own emails and pictures can now help decide which ads you see. The good news is that this only happens if you opted in, and you can check your settings and switch it off in about five minutes.

I am Muhammad Hafeez, and I write plain-English guides to the settings that quietly control your online life. In this article I will explain exactly what changed, ask the one question that decides whether you are affected, and walk you through the three checks that put you back in control.

What Actually Changed on October 16 (In Plain English)

The old policy wording was simple: Google did not use the content of your Drive files, Gmail messages or Photos for personalized ads. The new wording, effective October 16, 2026, keeps that promise but adds an exception — unless you choose to make data from these services available to other Google services that support personalized ads.

The door that exception opens is a feature called Personal Intelligence. It lets you connect your apps — Gmail and Google Photos — to Search and to Gemini, so the AI can answer questions using your own content: "What hotel did I book for next month?" or "Show me my photos from the lake trip." It is genuinely useful. But once connected, summaries and inferences from that content may also be used to show you ads, and Google is already testing ads in AI Mode for connected users.

Two things this does not mean. It does not mean Google suddenly scans every inbox for ads — the change applies only to people who chose to connect their apps. And it does not mean a human is reading your email; this is about automated systems drawing inferences. The change was widely reported in late October 2026 by outlets including Android Authority, The Hacker News and 9to5Google, which is why now is a good moment to check where you stand.

Are You Affected? The One Question That Decides It

Here is the only question that matters: have you ever connected Gmail or Google Photos to Gemini or to Search's Personal Intelligence features — for example, tapping "Connect" so the AI could search your email or find your photos?

• Yes, or not sure — do the three checks below. Each takes a minute or two.
• Definitely never — the October change does not touch your content. Check 3 (My Ad Center) is still worth 30 seconds of your time.

Two honest notes before you start. First, this feature is opt-in, and Google has not yet offered it in the UK or the EU — so if you are reading from the UK, the Personal Intelligence settings below may simply not appear in your account yet. Checking anyway takes two minutes. Second, rollouts vary from account to account, and Google adjusts menu names from time to time, so treat the steps below as a map rather than a script: if a label on your screen differs slightly, you are still in the right neighborhood.

Check 1: Disconnect Gmail and Photos in Search Services Personalization

This closes the Search side of the door. You will use the same Google Account you signed in with when you first created your Gmail account — make sure you are signed into the right one.

1. Go to myaccount.google.com and confirm the profile photo matches the account you want to check.
2. Open Data & privacy.
3. Scroll to the personalization settings and open Manage Personalized Recommendations in Search services (the exact wording may vary slightly as Google rolls this out).
4. If Google Workspace (Gmail and Drive) or Google Photos shows as connected, disconnect it.

Once disconnected, Search's AI features can no longer pull on your email or photo content — and that content can no longer feed personalized ads through this route.

Check 2: Disconnect Apps Inside Gemini's Personal Intelligence Settings

This second check catches people out, because Gemini keeps its own connection switch, separate from Check 1. Disconnecting in one place does not necessarily disconnect the other.

1. Open the Gemini app, or Gemini in your browser.
2. Tap your profile picture and open Settings.
3. Open Personal Intelligence, then Connected Apps.
4. If Google Workspace or Google Photos is switched on, turn it off.

If both Check 1 and Check 2 show your apps as disconnected, your Gmail and Photos content is not feeding Google's AI personalization — and, through it, your ads.

Check 3: My Ad Center — Turn Off Personalized Ads Completely

Even with nothing connected, Google still personalizes ads using your activity, such as your searches and the videos you watch. My Ad Center is the master switch for all of it.

1. Go to myadcenter.google.com.
2. Find Personalized ads and set it to Off.

You will still see ads — this does not block them — but they will no longer be tailored using your activity or inferences from connected content. While you are there, you can also browse the topics and brands Google thinks you are interested in, which is an eye-opening two minutes in itself.

The Part Disconnecting Does Not Undo: Search Services History

Here is the detail most guides skip. Disconnecting stops future use of your content. It does not erase what was already collected — activity saved from Search's AI features and connected services (your Search services history) may still be stored in your account.

To deal with it, go back to Google Account → Data & privacy and look under the history settings. From there you can review the activity saved from Search services, delete entries you do not want kept, and set an auto-delete period (for example, every 3 or 18 months) so it does not build up again. The exact names and placement of these controls vary a little by account, but everything lives under Data & privacy.

What You Lose If You Switch It Off (An Honest Trade-Off)

I will not pretend there is no cost, because there is — it is just a cost many people will happily pay:

• You lose the personal answers. Gemini and Search will no longer answer questions about your own emails, bookings or photos.
• AI Mode becomes generic again. Search's AI answers stop taking your content and context into account.
• Your ads get less relevant — which some people find more annoying, not less. Untargeted ads are still ads; they are just random ones.

What does not change: Gmail, Photos, Drive and Search all keep working exactly as before. Disconnecting deletes nothing — your emails and photos stay right where they are, and you can reconnect later if you change your mind.

A 5-Minute Privacy Routine for Your Google Account

While you are in your account settings, this short routine covers the rest of the basics:

1. Do Check 1 and Check 2 above — disconnect any app you do not actively use.
2. Spend 30 seconds in My Ad Center and set personalized ads the way you actually want them.
3. Set Web & App Activity to auto-delete, so old activity does not pile up forever.
4. Under Security → Third-party apps with account access, remove anything you do not recognize or no longer use.
5. Make sure this account has a strong, unique password and 2-Step Verification switched on. If you tend to reuse one password everywhere, read our guide on why the password you reuse is your biggest online risk — it is the single most valuable ten minutes you can spend on your accounts.

Common Mistakes to Avoid

• Disconnecting only inside Gemini and assuming Search is covered. There are two separate switches — check both.
• Checking the wrong Google account. Many people have two or three accounts. Verify the profile photo and email address before changing anything.
• Thinking "personalized ads off" deletes your data. It does not — ad personalization and your stored history are separate controls, as Check 3 and the history section above show.
• Believing the viral version of the story. Posts claiming Google now reads everyone's Gmail for ads are wrong; this applies only to accounts that connected their apps.
• Deleting the Gemini app and thinking that disconnects your data. The connection lives in your Google Account, not in the app — deleting the app changes nothing.

Frequently Asked Questions

Is Google reading my Gmail to show me ads now?

Only if you opted in. The October 16, 2026 policy change applies to content from accounts that connected Gmail or Photos to Search or Gemini through Personal Intelligence. If you never connected them, your content is not used this way.

I am in the UK. Do I need to do anything?

Personal Intelligence connections are not yet offered in the UK or the EU, so the settings in Checks 1 and 2 may not appear in your account at all. My Ad Center (Check 3) works everywhere, though, and is worth setting to your preference.

Will disconnecting delete my emails or photos?

No. Disconnecting only removes the link between the services. Your Gmail messages and Photos library stay exactly as they are, and you can reconnect later if you change your mind.

Does turning off personalized ads remove ads completely?

No. You will still see ads on Google services and YouTube — they just will not be tailored using your activity or inferences from connected content.

I do not remember connecting anything. How can I be sure?

Do Checks 1 and 2. Both screens show clearly whether Google Workspace and Google Photos are connected. If they are off in both places, nothing is connected, and the October change does not affect your content.

The Bottom Line

The October 2026 change is real, but it is narrower than the scary headlines: it is opt-in, it flows through two specific connections, and you hold both switches. Disconnect Gmail and Photos in Search personalization, disconnect them again inside Gemini, set My Ad Center the way you want it, and clear the history that disconnecting leaves behind. Five minutes, and the choice about your own content is yours again — which is where it should have stayed all along.
