You can make your profile private under the ‘Settings’ section in the app.
If you are on the ‘Now Playing’ screen, touch the back arrow in the upper left corner (near the Pandora icon). Then select the ‘Settings’ tab.
Next select ‘Privacy.’ There you can uncheck the box next to ‘Make Profile Public’ and this will restrict anyone else from seeing your web profile.
You can also uncheck ‘Enable Comments.’ This will restrict other listeners from leaving comments on your web profile or stations.
Unchecking the Facebook section will block your account from importing your Facebook information. After making any changes a blue ‘Settings Changed’ button will appear at the bottom of the screen.
