Introduction: Why You Keep Seeing Ads for Things You Just Talked About
Have you ever searched for a pair of shoes, and then seen shoe ads everywhere for days? Or browsed a holiday destination once, only to have travel ads follow you from app to app? You are not imagining it, and your phone is not secretly listening to you. What is happening is called personalised advertising: advertisers use information about your interests, your app usage, and your activity to show you ads they think you are more likely to tap.
Some people find personalised ads useful, because the ads feel more relevant than random ones. Many others find them uncomfortable, because they reveal how much is known about their habits. The good news is that on Android, you are not stuck with the default. You can turn off ad personalisation in your Google settings and in your phone’s privacy settings, limit what advertisers can track, and reduce how closely ads follow you around.
In this guide, you will learn how to turn off personalised ads on Android, step by step. We will cover the main Google ad setting, your phone’s advertising ID, app-by-app permissions, and the extra switches in popular apps and browsers that keep personalising ads even after you change the main setting. By the end, you will know exactly what each switch does, what it does not do, and what to expect afterwards, including one important fact: turning off personalisation does not remove ads, it just makes them less tailored to you.
What Are Personalised Ads, and How Do They Work?
Personalised ads are ads chosen for you based on information collected about you. On Android, the main sources are your Google account activity, such as searches and videos you watch, the apps you use, and a unique advertising ID on your phone. Advertisers never see your name or your personal details directly. Instead, they see a profile of interests, such as “interested in cooking” or “recently searched for flights”, and they show ads matching those interests.
Your advertising ID is a key part of this system. It is a random-looking code assigned to your device that advertisers and apps use to recognise the same device over time, without knowing who owns it. When you reset this ID, advertisers lose the thread connecting your past activity to your future activity, and they have to start over. When you delete it, newer versions of Android stop sharing it with apps altogether for advertising purposes.
It is also worth understanding what personalised ads are not. Turning them off does not stop companies from collecting all data, and it does not make you anonymous online. Your carrier, your apps, and websites you visit still collect information for their own purposes, such as security and basic statistics. What changes is that Google will no longer use your activity to tailor the ads you see in Google services and in apps that use Google’s advertising system.
Before You Start: What You Need to Know
You need an Android phone and a few minutes. That is all. You do not need to install any app, pay for anything, or create a new account. Everything in this guide uses settings already on your phone. The exact menu names vary a little between phone brands: Samsung, Pixel, Xiaomi, and others all organise their Settings app slightly differently, but the Google settings are the same everywhere because they are part of your Google account.
There is one important expectation to set before you begin. After you turn off personalisation, you will still see ads. They will simply be generic, based on the app you are using or the general time of day, rather than based on your interests. Some people are surprised by this and think the setting did not work. It did work; the ads just did not disappear, because free apps and websites still need advertising to survive. If your goal is fewer ads overall rather than less personalised ads, you need an ad blocker or a paid version of the app, which is a different solution.
Also note that changing settings on one device does not always change them everywhere. Your Google ad setting applies to your Google account, so it follows you to other devices signed in to the same account. But some settings, like your phone’s advertising ID, are specific to that one phone. If you use a tablet as well, repeat the device-level steps there too.
Step 1: Turn Off Ad Personalisation in Your Google Account
Open the Settings app on your Android phone. Tap Google, then look for an option about ads or privacy. On many phones, the path is Settings, then Google, then Ads or Privacy, then Ads. If you cannot find it there, open the Google app, tap your profile picture, then Manage your Google Account, then Data and privacy, then scroll to the ads section. Both routes lead to the same setting, which is called Ad personalisation.
On the Ad personalisation screen, you should see a switch that is currently on. This switch controls whether Google uses your activity, such as your searches and the videos you watch, to personalise ads for you. Tap the switch to turn it off. Google will usually show a confirmation message explaining what will change. Read it, then confirm.
Once it is off, Google will stop using your account activity to tailor ads in its services and in partner apps that use Google ads. This is the single most important switch in this guide, and it takes effect for your whole Google account, not just this phone. If you later change your mind, you can return to the same screen and switch it back on at any time.
Step 2: Delete or Reset Your Advertising ID
While you are in the same area of Settings, look for the advertising ID option. On many phones it sits on the same Ads screen, labelled “Delete advertising ID” or “Reset advertising ID”. The exact option depends on your Android version. Newer versions offer deletion, which is the stronger choice. Older versions offer a reset, which replaces your ID with a new random one.
If you see “Delete advertising ID”, tap it and confirm. After deletion, apps will no longer receive your advertising ID for ad targeting, although they may still show you generic ads. If you only see “Reset advertising ID”, tap that instead. Resetting breaks the link between your past activity and your future activity, which is still a meaningful improvement, even though a new ID is created.
Think of it this way: turning off personalisation in Step 1 tells Google not to use your activity for ads, and deleting or resetting the ID removes the label that apps use to recognise your device for advertising. Doing both together gives you a cleaner result than either step alone, so it is worth taking the extra few seconds.
Step 3: Review Location and Activity Settings That Feed Ads
Personalised ads do not only come from your advertising ID. Location history and app activity can also feed into the profile advertisers use. To review these, go to your Google Account’s Data and privacy section. You can reach it from Settings, then Google, then Manage your Google Account, or from any Google app by tapping your profile picture.
In Data and privacy, look for Web and App Activity, Location History, and YouTube History. Each of these has its own switch. Turning off Web and App Activity stops Google from saving your searches and app usage to your account, which also stops that information from being used for ad personalisation. Turning off Location History stops Google from building a record of places you have been. You can also delete past activity from these screens if you want a fresh start.
You do not have to turn everything off. Some people like keeping their search history because it makes Google Search and Maps more useful. The point is to make a conscious choice. If ad personalisation bothers you, these history settings are the next most powerful switches after the main ad setting, because they control the raw material that personalisation is built from.
Step 4: Control App Permissions That Let Apps Track You
Individual apps can also collect information for advertising, especially location and nearby device information. To review this, open Settings, then Privacy, then Permission manager. Look at Location first. You will see which apps have access to your location all the time, only while using the app, or never. For apps that do not need your location to work, such as games or shopping apps, change their permission to “Allow only while using the app” or “Don’t allow”.
Next, check the “Nearby devices” permission if your phone shows it. Some apps use this to detect other devices around you, which can be used for tracking. Only grant it to apps that genuinely need it, such as smart home or headphone companion apps. Also review the “Physical activity” permission, which some apps use to infer when you are walking, running, or driving.
This step takes a few minutes if you have many apps, but you do not need to review every app in one sitting. Start with the apps you use least and trust least. Social media, shopping, and free games tend to be the most aggressive collectors, so they are the best place to start.
Step 5: Turn Off Personalised Ads Inside Popular Apps
Even after changing your Google settings, some apps run their own ad personalisation. Social media apps, in particular, have their own advertising settings inside the app, separate from Google’s. If you use social media apps, open each one’s settings and look for an ads or privacy section. You will usually find an option like “Personalised ads” or “Ads based on your activity” that you can switch off.
Shopping apps and browsers deserve attention too. Many browsers have a setting to block third-party cookies or to send a “Do Not Track” request, which some advertisers respect. In Chrome on Android, you can go to Settings, then Privacy and security, then Third-party cookies, and choose to block them. This can reduce tracking across websites, although it can occasionally break a website that relies on cookies to keep you signed in.
You do not need to hunt through every app you own. Focus on the handful of apps where you spend the most time and see the most ads. Those are the ones shaping your ad experience. Turning off personalisation in three or four major apps, plus the Google setting, covers the vast majority of the personalised ads most people see.
Step 6: Check That the Changes Took Effect
After changing the settings, give it a little time. Ad systems do not update instantly, and you may still see personalised ads for a day or two while older data works its way out of the system. This is normal and does not mean the setting failed. After a few days, the ads you see should feel noticeably more generic.
To verify, return to the Google Ads settings screen and confirm that Ad personalisation is still off and that your advertising ID shows as deleted or reset. If either has reverted, check whether you changed the setting on a different Google account than the one your phone mainly uses. Many people have more than one Google account, and the ad setting is per account, so make sure you changed it for the account that is actually signed in on your phone.
Also test in practice. Browse a topic you have never shown interest in before, then notice whether ads for that topic start following you. With personalisation off, that follow-you-around effect should be much weaker or absent. If ads still feel eerily specific, check the in-app settings from Step 5, because an individual app may still be personalising on its own.
Tips for Keeping Ads Less Personal Over Time
- Repeat the advertising ID reset every few months. It takes seconds and breaks any new tracking thread that has built up.
- Review new apps’ permissions when you install them. Deny location and nearby-device access unless the app clearly needs it.
- Use your browser’s private or incognito mode for searches you do not want tied to your account, while remembering it does not make you anonymous.
- Sign out of social media apps when you are not using them, or use their mobile websites instead of the apps, to reduce background tracking.
- Check your Google account’s ad settings after major phone updates, since updates occasionally reset privacy switches.
- Remember that free apps fund themselves with ads. If an app’s ads bother you even when generic, consider its paid version or an alternative app.
- Teach family members the same steps on their phones, especially children, so their ad profiles are limited from the start.
Troubleshooting: When Ads Still Feel Personal
If ads still seem tailored to you after a week, the most likely explanation is an in-app setting you missed. Social media and shopping apps personalise ads using their own data, independent of Google’s switch. Open the settings of the app where you see the personalised ads and look for its own ad personalisation option.
Another possibility is that you changed the setting on the wrong Google account. If your phone has two accounts, the ad setting for the secondary account does not affect the primary one. Go back to the Ads screen and check which account is shown at the top, then switch accounts and repeat the steps if needed.
Contextual ads can also feel personal by coincidence. An ad for shoes inside a sports app, or a travel ad on a travel website, is chosen based on the app or site you are using, not based on your profile. That is normal generic advertising, and it does not mean your settings failed. The test is whether ads for a specific product follow you across unrelated apps for days. If they do not, personalisation is off.
If a website stops working properly after you block third-party cookies, you can allow cookies for that one site while keeping them blocked elsewhere. In Chrome, site-specific settings let you make exceptions without undoing your overall privacy choice. This keeps the balance between privacy and convenience that works for you.
Frequently Asked Questions
1. Will turning off personalised ads remove all ads?
No. You will still see ads, but they will be generic rather than tailored to your interests. Free apps and websites rely on advertising, so removing ads entirely requires an ad blocker or a paid subscription where offered.
2. Does turning off personalisation stop all tracking?
No. It stops Google from using your activity to personalise ads, and deleting your advertising ID limits app-based ad tracking. Companies still collect data for security, statistics, and basic service operation. For stronger privacy, combine these steps with careful app permissions and private browsing habits.
3. Do I need to repeat these steps on every device?
The Google account setting follows your account to other devices, but device-level settings like the advertising ID are per device. Repeat the device steps on each Android phone or tablet you use.
4. Why do I still see personalised ads in one particular app?
That app likely has its own ad personalisation setting separate from Google’s. Open the app’s settings, find its ads or privacy section, and switch off personalisation there as well.
5. Will turning off personalisation affect Google Search or Maps?
Turning off ad personalisation alone does not change Search or Maps results much. If you also turn off Web and App Activity or Location History, Search and Maps may become less personalised, such as fewer tailored suggestions. You can keep those histories on and still have ad personalisation off if you prefer.
6. Is it safe to delete my advertising ID?
Yes. Deleting or resetting it only affects advertising. Your apps, accounts, purchases, and data are not affected. Some apps may show you less relevant ads afterwards, which is exactly the point.
Final Thoughts: Ads You Did Not Ask to Be Followed By
Personalised ads can feel helpful at first, until the day an ad knows a little too much about a private search or a gift you were planning as a surprise. Taking a few minutes to turn off ad personalisation, delete your advertising ID, and review app permissions puts you back in charge of that balance. You will still see ads, but they will no longer be built from a detailed picture of your life.
Privacy is rarely a single switch. It is a handful of small choices, repeated occasionally, that add up to a much quieter digital life. Start with the Google setting in this guide, add the advertising ID step, and then tidy up the apps you use most. Your future self, browsing without a trail of yesterday’s searches following behind, will appreciate it.
