Useful ? – iSafeVault - Secure Private Folder.s Manage.r Review

So far I used the app, it's good enough... I mainly started using this app bcoz of making some of my notes locked frm public... Bt I am missing one feature in it... And tht is 'I want to backup my notes through mail directly frm each note like the default note app in I-phn'... Can anyone suggest me for this? Other than that the app is useful ?
