We support 128-bit and 256-bit encryption. We have no access to the keys. In the event that any of our customers lost their encryption phrase, we would not be able to restore the data.

edit: Well we also take operational and technical security precautions to validate our data integrity on a real-time basis. Our facilities are monitored on hardware and network levels 24/7/365. And we meet Federal HIPAA guidelines for privacy and security.
