Samsung has officially released its Secure Folder app for the Galaxy S7 today, following a leaked version of the app that showed up earlier this week (which also may have shown off the Galaxy S8).

Secure Folder serves as an encrypted location for users to store personal or sensitive notes, pictures, contacts, apps, or documents. The app uses Samsung’s Knox security features to lock the files within, only making them accessible through a passcode or biometric security. The feature originally launched on the Galaxy Note 7, and has since made its way to the international Galaxy A series, but today’s launch marks the return of Secure Folder’s availability in the US.

The only caveat is that you’ll need to be running Android 7.0 Nougat to use Secure Folder, which may or may not be available depending on your carrier of choice. Assuming you’ve got that set, Secure Folder is available now to download from Galaxy Apps.
