I built this site to meet my own needs and share it because I believe it can be very broadly useful. However, I cannot make any promises regarding service levels, accuracy of data or computations, or the quality of the software. (Although frankly I think it's pretty good and pretty bug free).
While I back up the database nightly, there is a feature to back-up your data to a spreadsheet - it's not a bad idea to use that now and then just in case.
If you find a bug or have a feature request, let me know, and I will see what I can do.
