From Vinod Nair:
Dooth is a secured collaboration suite that includes secure and encrypted email, calendar, chat,file management and sharing that protects your personal and business information.You can essentially do everything on Dooth that otherwise requires you to use multiple other free services. Dooth ensures that all files uploaded are encrypted, and added a provision that every email people send or receives is encrypted. Dooth does not read your email, does not mine your data. You can easily communicate with any part of the world end-to-end encrypted.Dooth means a messenger. In olden days, a king or queen sent messages to other kings and queens through a Dooth. The job of the Dooth was to deliver the message discreetly and securely. Often times these messages were sensitive and critical. Jeopardizing these messages had devastating effects. In the event of a security breach or potential threat to a message, a Dooth would fight until his last breath to safeguard the message. With no technology around, a message in the hands of a Dooth was far more secure than the level of security we typically experience today even with all of our security protocols, software and devices.
