Modify account settings
You can make changes to your account settings at any time. Sign in to your Google Trusted Stores merchant account at http://www.google.com/trustedstores/sell and click on any of the links under the “Setup” section in the left-hand navigation panel.
If you need to modify your settings after your application has been submitted, make sure to return to the “Overview” page and click on the Apply modifications button to save your changes.
Some account updates, such as your notification and support emails, require additional validations, and the Apply modifications button may be disabled until validations have been completed.
