Storing the Files You Can't Afford to Lose: A Look at Vaulternal

Most of us keep our important files scattered across half a dozen places. Some are in Google Drive. A few sit on an external hard drive in a desk drawer. The really sensitive stuff — scans of documents, a spreadsheet of passwords, a folder of family photos, a letter you wrote and never sent — is usually in whichever cloud folder was most convenient the day you saved it.

That works, right up until it doesn't.

Mainstream cloud drives are built for collaboration and convenience, not confidentiality. They aren't really private file storage in any meaningful sense — your files sit on company servers in a form their staff could theoretically read. Hard drives fail without warning. And none of these options solve a second, quieter problem: how do you make sure specific files reach specific people at the exact moment they actually need them — not sooner, not later?

That's the gap Vaulternal — an encrypted file vault is built for. It combines conditional access with scheduled file delivery in the same product.

Three jobs, one product

The product is organized around three actions: Store, Update, Deliver.

Store. Files are encrypted on your device before they ever leave it, using AES-256-GCM. The encryption key is derived from your own credentials and never touches Vaulternal's servers. This is zero-knowledge encryption in the strict sense — the company running the service literally cannot read your files, because they don't have the key. If their infrastructure were breached tomorrow, an attacker would find ciphertext and nothing else.

Update. A vault full of stale files isn't much use. Vaulternal prompts you to review your contents on a quarterly rhythm — a few minutes to confirm what's current, add new documents, remove what's no longer relevant. The ritual matters: it keeps the vault living rather than sedimentary.

Deliver. This is where Vaulternal separates itself from standard encrypted storage. You configure the conditions under which specific files are sent to specific recipients — a form of conditional access that doubles as a future delivery mechanism. The triggers can be time-based (release a file on a specific date), inactivity-based (send it if I haven't checked in for ninety days), or manual. A birthday letter to your daughter, scheduled for her 21st. A document packet for your spouse if something happens to you. A project handoff to a collaborator on a fixed date.

Who it's for

Anyone with files that shouldn't be easy to access, but also shouldn't be impossible to find when someone needs them. People who use password managers know this problem intuitively — strong security creates access problems for the people you'd actually want to reach your stuff. Standard secure file sharing tools solve part of the problem: they protect files in transit and at rest. Vaulternal adds the timing dimension on top.

It's particularly useful for people who've realized that "I'll just tell them the password if something comes up" isn't really a plan. Spouses who manage household accounts separately. Parents with young children. Creators sitting on unreleased work they want released on a schedule. Anyone in a long-distance relationship with stakes higher than a shared Spotify playlist.

The technical side

For people who care about the details: client-side encryption with AES-256-GCM, secp256k1-ECIES key wrapping, and distributed storage across Arweave, IPFS, and Polygon. BIP-39/32 hierarchical deterministic key derivation means you control your own key material. The architecture page on the site goes deeper if that's the kind of page you enjoy reading.

Pricing

There's a free tier — 50 MB, one delivery rule — to try it out. Paid plans start at $8.33/month billed annually for unlimited storage. The pricing leads with capability rather than gigabyte counts, which is a refreshing choice in a category that usually sells storage by the pound.

Most tools in this space handle storage. A few handle secure file sharing well. Vaulternal is one of the first that also handles timing — the question of when a file reaches the person it was meant for. For anyone who's ever written something they intended to send later, or organized documents someone else might need to find without your help, that's a meaningful distinction.
