To sign out of the NOOK App on your NOOK Tablet 7", NOOK Tablet 10.1", or Samsung NOOK Device, follow these steps:
1. From the bottom navigation bar, select Profile
2. Tap the Sign Out button in the left column
Signing out of the NOOK App will remove your BN.com account from the device. You will still be able to use the non-NOOK features of the device without being signed into a NOOK account.
