I'm considering purchasing Handy Safe for my E61.

Anyone know if the data is also encrypted and protected in the PC Desktop Application?

They are both encrypted with a good encryption, but I have less confidence with the company. The desktop version doesn't have any auto-lock, so if you forgot to lock your PC, your handysafe will open forever.

I didn't get any response after giving feedback to company. the phone version is better, and yet there is no better alternative.

I get the some vibe as you did, I emailed them this question last week, no answer yet. :(

I guess Handy Safe is the least crappy solution out there.
