Manage your ad privacy in Chrome

Chrome works to keep you safe and protect your privacy while you browse. New features help protect your identity and give you more control over how advertisers choose which ads to show you. These new features will roll out gradually on computers and Android devices.

Chrome notes your topics of interest based on the sites you browse and how often you visit them. Sites can also store info with Chrome about your interests. As you keep browsing, Chrome may be asked to share stored info about ad topics or site-suggested ads to help give you a more personalized ad experience. To measure the performance of ads, limited types of data can be shared among sites and apps.

You can opt out of these features in your Chrome settings anytime. As you browse, an ad you get may be personalized depending on these settings and the policies of the sites that you visit.

Edit ad privacy settings

  1. On your device, open Chrome.
  2. At the top right, tap More and then Settings.
  3. Tap Privacy and security and then Ad privacy.
  4. Select the ad feature you’d like to turn on or off.
Manage ad topics

To personalize your ad experience, Chrome notes your topics of interests based on the sites you browse and how frequently you visit them. Chrome can share up to 3 topics at a time with sites. You can block topics you don’t want shared with sites. When you block a topic, Chrome won't share that topic again, but you may still get ads related to the topic. To further protect your privacy, Chrome automatically deletes your topics of interest that are older than 4 weeks.

To block a topic:

  1. On your device, open Chrome.
  2. At the top right, tap More and then Settings.
  3. Tap Privacy and security and then Ad privacy and then Ad topics.
  4. Under "Your topics," select topics to block.

Tips:

  • Based on your recent browsing history, it may take a while for a list of topics to appear. You also may not get a list of topics if this feature hasn't been adopted by the sites that you visit.
  • When on a site, you can check if Chrome shared your topics of interest with the site. In the address bar, tap View site information Default (Secure) and then Ad privacy.
Manage site-suggested ads

To help deliver a personalized ad experience, sites can recommend and then store ad suggestions about things you may like. As you continue to browse, you may get ads based on suggestions from related sites. Chrome automatically deletes suggestions that are older than 30 days, but they may reappear if you revisit that site.

If you don’t want a site to suggest ads for you, you can block the site. Once blocked, any associated ad suggestion data is deleted. Blocked sites will no longer store ad suggestions with Chrome, but you may still get ads related to those sites.

To block sites:

  1. On your device, open Chrome.
  2. At the top right, tap More and then Settings.
  3. Tap Privacy and security and then Ad privacy and then Site-suggested ads.
  4. Under "Sites," block a site from the list.

Tips:

  • Based on your recent browsing history, it may take a while for a list of sites to appear. You also may not get a list of sites if this feature hasn’t been adopted by the sites that you visit.
  • When on a site, you can check if the site is suggesting ads for you. In the address bar, tap View site information Default (Secure) and then Ad privacy.
Ad measurement
As you browse, sites share a limited amount of data to measure ad performance, such as whether you made a purchase after visiting a site.
