Vaultine for Freelancers — One Device, Several Clients' Files

Situations this covers

—Contracts, invoices and confidential briefs from several clients living in one Documents folder.

—Screen-sharing on a call and needing to open a file without another client's name being visible in the same window.

—An NDA that says client material will be kept secure, on a laptop where 'secure' currently means a login password.

—A finished project you're contractually meant to hold onto, but shouldn't have sitting in the open for years.

—A stolen laptop that holds your own tax records and four clients' confidential work at the same time.

What does the work

Multiple separate vaults

One vault per client, kept apart from each other and from your own personal and financial files.

Folder import

Bring an existing client folder in whole, structure intact, rather than moving files one at a time.

Zero-knowledge design

The key is derived from your code on your device and never leaves it. There is no account and no server holding your files or your key.

Stealth auto-lock

The vault locks and cryptographic keys are cleared from memory the moment the app is minimized, which matters on a call you're screen-sharing.

Built-in secure viewer

Open documents and PDFs inside the vault, so nothing is decrypted into a folder another app or backup could reach.

Works on Windows, macOS, iOS and Android

The same vaults on the laptop you work from and the phone you answer clients on.

It accumulates rather than happens

No freelancer decides to keep several clients' confidential material in one unprotected folder. It arrives one project at a time, and by year three a single laptop holds contracts, briefs, credentials and finished work belonging to people who each assumed they were the only one.

That's the actual exposure, and it isn't solved by a login password. A login password decides who can sign in to the operating system. Pull the drive, connect it elsewhere, and the files open like any other files.

A vault per client, not one big locked box

Vaultine supports as many separate vaults as you need, each with its own contents. One client's material doesn't sit next to another's, which matters both practically and contractually: if you're ever asked what protects a particular client's files, "they're in their own encrypted vault" is a better answer than "they're in a folder on my laptop."

Folder import is what makes this realistic. An existing client directory comes in whole, structure intact, instead of being rebuilt one file at a time.

The screen-share problem

The everyday risk isn't a thief, it's a shared screen. Vaultine's stealth auto-lock closes the vault and clears the keys from memory the moment the app is minimized, so switching to your browser mid-call doesn't leave a vault sitting open behind it. The built-in viewer helps for the same reason: files open inside the vault rather than being decrypted into a folder something else could index or back up.

The same vaults on every device you work from

Client work follows you between a laptop and a phone, and often a second machine. Vaultine runs natively on Windows, macOS, iOS and Android, with no account tying any of it together, so the vaults you set up are the same ones everywhere rather than separate copies drifting apart.

The bottom line

Nobody sets out to keep four clients' confidential files in one unprotected folder. It just accumulates, one project at a time, until a single lost laptop is a problem with several other people's names on it. Vaultine gives each client their own encrypted vault on the same device you already work from, and makes moving an existing folder in a one-step job rather than a chore you postpone.

Frequently asked questions

Can I keep a separate vault for each client?

Yes. Vaultine Pro supports as many separate vaults as you need, so one client's material never has to sit alongside another's. The free tier covers one vault of up to 10 files, which is enough to try it rather than run a full client list.

Does Vaultine hold a copy of my clients' files?

No. The encryption key is derived from your code on your device and never leaves it, and there is no account or server holding your files. Optional encrypted backup to your own Dropbox is encrypted before it leaves the device, so it is unreadable there too.

What happens if I minimize the app during a screen share?

Stealth auto-lock closes the vault and clears the cryptographic keys from memory as soon as the app is minimized, so a vault left open isn't waiting there when you switch windows.

Can I move an existing client folder in without redoing the structure?

Yes. Folder import brings a full directory in with its structure intact, rather than requiring you to rebuild it file by file.

Three clients' files shouldn't share one folder.
