Local-first encrypted vault
Encrypted on your machine.
Nowhere else.
A desktop vault for your notes and files. No accounts, no sync, no cloud.
Look inside
This is the whole thing.
No onboarding tour, no dashboard, nothing to set up. You unlock the vault and you’re already in, right there with your notes and files.

Void makes no network requests.
No sync, no accounts, no telemetry, not even update checks. The app stays completely offline. Your data only leaves your device when you decide to export it yourself.
Write
Notes that don’t feel like a database.
A real rich-text editor, not just a box for plain text. And since every save is versioned, nothing you write is ever truly lost.
- Rich text, checklists, links & inline images
- Custom templates for the notes you write often
- Up to 30 versions per note, so you can restore any draft

Every file. Encrypted, previewable, yours.

Security
No backdoor. No exceptions.
Everything gets encrypted on your machine before it ever touches the disk. There's no backdoor. Without your password or recovery words, nobody can read your data, and that includes us.
What happens before anything touches disk
Recovery
Local-first shouldn’t mean fragile.
No cloud means there’s no “reset password” email to fall back on, so Void gives you two solid ways to never lose your vault.
Forgot your password?
The first time you unlock Void, it shows you a 24-word recovery key. Keep it somewhere offline and you can always get back in.
Shown once · never stored on disk
New machine?
Export the whole vault to a single encrypted .void archive, then import it wherever you like.
Backup health, tracked for you
Windows
Built into your desktop, not bolted on.
Void leans on the parts of Windows that make a vault feel right at home, and the ones that help keep it private.
Quick capture
Copy some text, hit the shortcut, and it lands in a fresh note from anywhere.
Lives in the tray
Tuck it into the system tray and unlock it again with a single keystroke.
Launch at startup
Start it with Windows if you like, locked and ready whenever you are.
Hidden from capture
Keep the window out of screenshots and screen recordings.
Void vs. the cloud
Everything the cloud apps do. None of the cloud.

The questions a local vault should answer.
Is Void really fully offline?
Yes. It makes no network requests at all: no sync, no accounts, no telemetry, not even update checks. The only data that ever leaves your machine is a backup you decide to export yourself.
How do I sync between machines?
There's no cloud sync, and that's on purpose. Instead, you export your vault to a single encrypted .void file and import it wherever you want, whether that's a USB stick, your own drive, or anywhere else you trust.
What if I forget my password?
The first time you unlock Void, it hands you a 24-word recovery key. Keep it somewhere safe and offline and you can always get back in. Without the password or those words, nobody can open the vault, and that includes us.
If my laptop is stolen, can someone read my notes?
No. Everything is encrypted on disk, and the keys only live in memory while the vault is unlocked. They're wiped the moment you lock it, when it auto-locks, and when you quit the app.
What happens if Void goes away?
Your vault is just files on your own disk, encrypted with a standard, well-documented cipher (ChaCha20-Poly1305). Nothing about it depends on a server staying online, so it keeps working no matter what happens to us.
Does it run on Mac or Linux?
Right now Void is built for Windows 11. The vault format itself isn't tied to Windows, but for the moment the app only ships there.
How much does it cost?
Nothing at all. Void is a free download, with no account, no subscription, and no upsell waiting around the corner.
Your vault is one download away.
Just one Windows installer. No account to create, no telemetry, no update checks. Set a password and you’re in.
