Re: encrypted

Makes sense for sensitive information that's updated daily, especially on a phone.

But it's kind of a big risk if you lose the phone, it's stolen or breaks down. I wouldn't use a machine-specific encryption for that. I would use a machine-independent encryption (that works elsewhere also, for example in Linux or Windows 7) and backup that encrypted file to a web-based storage (like gmail or dropbox).

Seems you have to do some research to get a solution that meets your needs.
