The Blackhold drive.

Spaces
Encrypted, persistent
Hidden
Look like empty disk
Network
Tor or your VPN, always

Small enough for a pocket.
Tough enough to live in one.

Inside

Built like a vault.

Plug in. Open your space.

Your desktop, files, Wi-Fi and VPN are back. Every other space stays sealed.

KeepDesignInsideOpen
01 Spaces

Each space is a whole computer of its own.

Pick a space, type its passphrase, and your files, apps, Wi-Fi networks and VPN are where you left them.

02 Encryption

Close it, and it is sealed.

One click. Closed, a space is an encrypted volume, unreadable without its passphrase, even with the drive in someone else's hands.

03 Hidden spaces

Some are hidden. They look like empty disk.

To anyone else, that part of the drive is free space. Its passphrase is the only way in.

It’s not about having something to hide. It’s about who wants your data.

01

Journalists & their sources

Publish from an unsafe place and talk to sources without exposing them.

With Keep

The draft can be reviewed by the local AI — it touches no server.

02

Living under domestic abuse

Search for help without the search being recorded on the machine.

With Keep

The computer goes back to how it was when the Keep comes out. No traces.

03

Activists & rights defenders

Bypass blocks and defend fundamental rights.

With Keep

Works on any borrowed computer, and leaves nothing on it.

04

Lawyers, doctors, accountants

Handle confidential cases on a computer that doesn't keep the case.

With Keep

Asking the AI about a client doesn't hand them to a third party — it's local.

05

Security researchers

Analyze suspicious files without risking your main machine.

With Keep

Every session starts identical to the last. One analysis never contaminates the next.

06

Anyone

Who wants more privacy in a world where freedom is under threat.

With Keep

The question isn't whether you have something to hide — it's who wants your data.

Any computer. Your rules.

Starts any 64-bit PC. Yours, a friend's, the library's.

Tor before anything else. The firewall is up before the network is.

The computer stays clean. Outside your spaces, the session ends at shutdown.

Panic key

Hold two keys for 3s: wipe and power off.

Drop alert

If the tunnel drops, the screen says so. Nothing reconnects on its own.

VPN browser

Exits via VPN, for sites that block Tor exit nodes.

Reproducible build

Rebuild and compare bit-for-bit. The diffoscope report is public.

Signed canary

A signed statement every week. If it stops, stop trusting.

Cold-boot safe

RAM is overwritten at shutdown. Nothing survives.

Fast enough to feel installed. Small enough to forget in a pocket.

Blackhold 1.0 is in final testing. Keeps ship at the release, and the release image will be public, so you can check what is on your drive.

Limits

What the Keep does not do.

Security products tend to oversell. This is where the Keep's protection stops.

  • It does not make you invisible.Tor hides where you connect from. What you type into a website still reaches that website.
  • It cannot recover a lost passphrase.Nobody can, us included. That is what the encryption is for.
  • It has not been audited yet.No outside team has reviewed Blackhold so far. This line changes when one has.
  • Hidden spaces protect the disk, not you.They help when someone looks at the drive. They do not change your situation.
