The app is not what you want when looking for privacy. Claims to have anonymous phone numbers and in their ToS states that the number your assigned uses your true identity and calling/texting is done through 3rd party applications. Also yea the encryption maybe good but they are in full cooperation with law so if your using this app to stay safe from prying eyes this is not the app for you. Also for business men "you grant us perpetual, worldwide, royalty-free, exclusive license to reduce, modify, adapt, publish, publicly display or distribute the content we see fit" Thank you.
