What information does Lochbox have access to on my device?

Lochbox works as a sandboxed soft-phone and messenger app.  It does not require any permissions from your phone to operate except for user convenience.  If the user wants to share photos, then the Lochbox app will need access to photos.  If the user wants to invite from the phone's contact list, then the Lochbox app will need those permissions.  If the user wants to be notified or accept a call while the phone is locked, then those permissions need to be granted.  Nothing is harvested from the phone to the cloud.  Lochbox is the opposite of Facebook, we don't want your data, we want your business entity to protect it.  The Key Server, running in your business' infrastructure is how this is accomplished.  All of the periphery devices that interact over the unsecure networks, have to pass the device, user-auth, and access control (ACL) checks before the Key Server securely delivers the decryption key to the device in order to show the protected content.
