Separate vaults, not one folder with everything in it
The practical problem with keeping client material next to everything else on a device isn't abstract — it's the moment someone else looks at the phone, whether that's IT, a courtroom exhibit, or a lost device. Vaultine supports as many separate vaults as you need, so a case can live entirely apart from your own files and from every other case.
Folder import matters for the same reason: an existing case file directory comes in as a folder, with its structure intact, instead of being rebuilt one file at a time.
No copy anywhere but the device
Vaultine's encryption key is derived from your code on the device itself and never leaves it. There's no account tying a vault to your name, and no server holding a copy of the files or the key. That's a factual description of the architecture, not a claim about satisfying any specific ethical wall or regulatory rule — those judgments are yours to make. What it does mean is that there is no vendor-side copy for anyone else to request or lose on your behalf.
One set of vaults, every device you actually use
A vault set up on the office laptop is the same vault on the phone used between meetings — Vaultine runs on Windows, macOS, iOS and Android as native apps, not a mobile-only tool bolted onto a desktop later.
