I was looking for a very long time a secure email provider for sending confidential and important documents or confidential emails which could be steal on other email providers. Also looking for a long time a way to store my documents securely also. for my first impression it seems the best email and storage provider currently with this great lifetime deal. It's a steal at this price!
Hope they will continuously update this app with new features , that android app is planned on the future and Fingerprint feature. 5 Tacos for supporting them !
