Vault
Private work, same flow
Vault lives inside the workspace. It keeps encrypted notes on your device, works offline, syncs devices you pair, and makes secret links that expire
- Encrypted notes and folders, searchable instantly
- Offline first, with the primary copy on your own device
- View once, a 60 second window, no select, tab switch lock and a DevTools guard
- Leave view once off and a link stays reusable until it expires
Privacy by design
Nothing to hand over
No file storage
During direct and local transfers, files exist only in the two browsers. Our servers never see them.
No account
No email, no password, no profile. Open a link and go.
Works offline
After the first visit the preparation tools run without a connection. Share when you're back online.
