I'm surprised this suggestion got so many up votes.
Users don't get a service here, they get a software solution (+updates)! Your data isn't stored in an account on a SafeInCloud's server. Your data is encrypted and stored wherever you specify and the only way to access it is to decrypt it with your master password.
Either get a few basic information about encryption or read the feature list. The latter states:
Zero-Knowledge security means that the application developer or any other person knows nothing about your data..."
AFAIK there are cryptographic measures to achieve something like: 5 people get a part of a key and any 4 of them are able to decrypt the data. But that are much more sophisticated implementations with even more pitfalls than basic encryption applications like SafeInCloud.
Instead better consider an organized overall emergency plan wich includes disclosure of your SafeInCloud master password together with other important data and information.
