From Richard Morena:
-Create a group and add contacts to it-Hide/Restore all contacts in a group with password protection(Contacts will be hidden on the phone)-Send message to contacts in the group .** Warning:If the app is deleted all hidden contacts will also be deleted. **Restore all contacts before you decide to delete the app . ** if there are notes in a contact it will be deleted once you hide the contact. ** favorites contacts that are hidden will only show the contact number ** this app will hide contacts on the phone but not block incoming calls from these contacts
