"Q. Is my stuff safe

Data security has always been of paramount importance. Now, with so many cloud data and social services available protecting your identify and security is of the utmost importance. ZeroPC is very serious about this topic. We have implemented several layers of security to protect your valuable content. All data transmission between your browser and ZeroPC is encrypted using SSL. This is the same level of encryption used by banks and other financial institutions.

We never store your credentials to connected services such as Evernote, Dropbox, Box.net, etc. Instead we have implemented an industry standard and very secure technique called "OAuth" to enable these connections. Using OAuth allows us to transfer control for each service to it's own highly secure login page. ZeroPC has registered and been validated with each of these sites. After you have successfully logged in to the site then their servers pass ZeroPC an encrypted "token". This token, along with our secret key, allow us to access the content in those services. As a user, you have complete and sole control. You may revoke this authentication at anytime.

We have implemented optional features within ZeroPC to further protect your account. This includes a desktop screen lock using a 4-digit PIN that you specify. We also allow you to generate a limited-use unique login security key. This key can be used in place of your ZeroPC username and password whenever you use an unfamiliar computer such as workstations at Internet Cafes. This keeps your username and password safe from key loggers and malware that may try to sniff this information on these unfamiliar computers" "
