One master password
Unlock the whole vault with a single passphrase. It is never written to disk — only used to derive a key in memory.

Features
Confidential by default
Built for people who want a real vault without shipping secrets to a SaaS. Encryption and isolation are first-class — not an afterthought.
Argon2id + AES-256-GCM
Memory-hard key derivation and authenticated encryption. Wrong password fails the auth tag — no silent garbage decrypt.
Local only
No account, no cloud, no sync. Outbound network from the app is blocked. Secrets live in one encrypted file on this PC.
Dashboard overview
Stats, security status, type breakdown, and recently updated items when you unlock.
Password generator
Cryptographic RNG with length and character options. Rejection sampling avoids modulo bias.
Clipboard clear
Copied secrets auto-clear after 30 seconds so they do not linger on the clipboard.
Idle auto-lock
Configurable auto-lock wipes the key from memory. Lock manually anytime from the sidebar.
Vault fingerprint
See a short integrity fingerprint of the encrypted file — confirm you are opening the vault you expect.
Process isolation
Crypto and file I/O stay in the Electron main process. The UI is sandboxed with context isolation.
Get started
Three steps to a locked vault
01
Install or portable
Run the Windows setup, or use the portable .exe with no install.
02
Create master password
Choose a strong passphrase. There is no recovery — that is by design.
03
Add secrets
Store logins, notes, and API keys. Search, copy, generate, and lock when done.
No password recovery. If you forget the master password, the vault cannot be opened. Store that passphrase safely.
