## What is LockZero Premium?

What if you needed that information… right now?

LockZero protects what matters most — passwords, cards, documents, notes and lists — directly on your device, fully offline and encrypted.

No account.  
No server.  
No automatic synchronization.  

Your data stays with you.

SECURITY

• AES‑256 encryption  
• User-defined protection phrase  
• Secure key derivation (PBKDF2)  
• Encrypted local backup  
• Session protection with PIN or biometrics  

Sensitive information never leaves your device.

---

ORGANIZE EVERYTHING IN ONE PLACE

• Passwords with URL and username  
• Structured card templates  
• Text notes  
• Checklists  
• Protected attachments  
• CSV import (Premium)  
• Offline OCR (Premium)

BACKUP

Export your encrypted vault file and restore it when needed.  
No server involved.

IMPORTANT

LockZero does not collect sensitive user data.

You are fully responsible for your protection phrase.  
If it is lost, access cannot be recovered.  
That is part of the security model.


## Version history (last 4 releases)

### 1.0.6 — 2026-05-18

- LISTS WITH ITEMS OF ANY LENGTH
  Long items now wrap to multiple lines. The edit field accepts multiline
  too, and the list scrolls to top automatically. Large lists (30+ items)
  now scroll all the way to the end.

- SMARTER SHARED-LIST IMPORT
  When receiving a list, the app asks which group to import into. If a note
  with the same title exists, you choose: replace, merge items, or cancel.

- BUG FIXES
  Fixed crash when receiving a `.lockzero` file from another LockZero install.
  Shared lists no longer prompt for a wrong export passphrase on import.
  Improved performance on large lists.
