Our software has been tested on many devices, operating systems and browsers, and we are constantly fine tuning the user interface, so it is easy to use wherever you use it. We always recommend you keep your own computer software up to date, but if your do experience an issue, please do let us know.
Our software is a web based application. At any given moment, there are no less than 4 different backups of the data. Additionally, the backups are stored in 3 different locations. The server is in a climate controlled data center with a backup power generator, and there are level 3 staff there 24 hours per day, 365 days per year. We have never experienced data loss where backup was even needed. However, we do encourage you to take a daily backup of your own which you can do under Tools and Settings > Database backup.
Here is pretty extensive list from our compatibility testing. If there is something you are using that is not in the below list, let us know and we will test it!

Amazon Silk (powers Kindle)
