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.

Settings.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.

To further protect your privacy, Chrome automatically deletes your topics of interest that are older than 4 weeks.
To block a topic:
- On your device, open Chrome.
- At the top right, tap More
- Tap Privacy and security
- Under “Your topics,” select topics to block.
Tips:

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.

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.
