Offline first
Every device keeps your vault, encrypted, in its own database. Unlock, read, fill and edit without a connection.
Instant sync
A change on one device reaches your others, and the people you share with, within seconds. Each device keeps the whole vault, so it works offline, and edits made apart are merged, not lost.

How it works
Save a login on your laptop. Vallkey encrypts it and sends it at once.
The server tells your other devices to sync, over a connection that carries no vault data.
Each device checks what it downloads against the vault's signed manifest before it trusts it.
The details
Every device keeps your vault, encrypted, in its own database. Unlock, read, fill and edit without a connection.
Edits to different fields merge, field by field. If two devices change the same field, the item keeps one value and your whole other version is saved as a copy.
If one device deletes an item while another edits it, the edit wins and the item comes back.
Devices also sync after every change and every five minutes, in case a message was missed.
A vault kept only on your devices can sync through a folder they share, such as iCloud Drive or Dropbox, with no server at all.
Availability
No. The web vault keeps nothing in the browser, so it needs a connection. The apps and the browser extension keep your vault and work offline.
That your device synced, and encrypted items with padded sizes. Not what changed inside them.
Vallkey opens soon. Join the waitlist to hear first.
