Your information is stored on a centralized high-end web server, that is connected to the internet permanently allowing you access to your information at any time and from any location.
There are no installation requirements, and you never have to worry about upgrades - everything is taken care of seamlessly behind the scenes.
Only users that have been provided with valid login details will have access to the system, and only they will be allowed to view the information that pertains specifically to them. Users can add as many email addresses to give access to the system as they want.
All of this happens via high security EV (Green Bar) SSL encryption similar to what online banks use which means that no one else will be able to view the information. You can rest assured that your data will always be available to you, and that it will be kept safe and secure at all times.
