Transparency and choice

People have different privacy concerns. The goal is to be clear about what information we collect, so that you can make meaningful choices about how it is used. For example, you can:

Review and control certain types of information tied to your Google Account by using Google Dashboard.

View and edit your ads preferences, such as which categories might interest you, using the Ads Preferences Manager. You can also opt out of certain Google advertising services here.

Use the editor to see and adjust how your Google Profile appears to particular individuals.

Control who you share information with.

Take information out of many of the services.
