Sounds cool Lane, Thanks for posting. I have been a purchasing user of a popular proprietary vault since this became more convenient than continuing to develop and use my own, more years ago than I care to count.
I never took to keepass, the other open source solution I know of, as this seemed, and still seems unnecessarily complex and user unfriendly to me, a typical complaint of programmer driven developments, apparently oblivious to the actual needs of the end users it is targeted at.
But I thoroughly agree the ideal maximum trust solution should be open source.
If the main user requirements of no-brain simplicity and convenience of use, cross-platform, synchronised database updating capability is observed, there is every possibility qvault could “wipe the board” of all the proprietary offerings out there, as open source is maximum trust.
I wish you well with that, more power to your elbow.
