This app is legit!

apotheosis51 I’ve been using this app for quite awhile and it just got better with the addition of the wallet. My computer knowledge is only basic but my girl could hack into just about anything and she couldn’t get past the encryption. That’s saying something. Look these guys up and you will see they are legit and on top of their game. I haven’t had the slightest problem with this app. It hasn’t even so much as frozen up on me.. not once. Between that and my girl’s inability to get through the encryption I have to say this is THE BEST privacy app I have ever used! That’s saying a lot as my privacy is of the utmost importance to me and I’ve been through dozens of trash apps. None could hold a candle to this one!!!

THE encrypted wallet and messenger app of the future!

This is by far the best messenger app and secure wallet you will come across. The encrypted messenger portion has been around for a few years and the wallet portion is fairly new. It is absolutely ahead of its time and is being updated on a daily basis with more amazing features to be launched in the near feature. If you need a safe place to confidentially store your files, your MONEY, video call, email and just casually chat with friends, this is the place to do it.
