Calculator Vault - Data Locker

Calculator Vault is a discreet data locker that hides photos, videos, audio, documents and notes behind a fully functional fake calculator. Enter a 4-digit PIN (press “=”) to unlock your private vault, set security questions for recovery, and customize settings like app language, changeable icon, and wrong-attempt limits.

Files are stored locally on your device for privacy — the app does not upload or share hidden data. Additional features include a built-in notepad, easy restore/unlock options, and support for multiple languages. Calculator Vault provides a simple, user-friendly way to protect sensitive files without drawing attention to the app.
