About this app
Calc+ Vault is a fully functional calculator that also protects your most sensitive files with AES-256 encryption. Enter your PIN on the calculator keypad to unlock a private vault — only you know it's there.
ENCRYPTED VAULT
• Notes, photos, videos, contacts, and documents stored with AES-256 encryption
• Files never leave your device unencrypted
• Biometric unlock — fingerprint or face in addition to your PIN
• Decoy PIN opens a separate empty vault for peace of mind
PRIVATE BROWSER
• Built-in browser that leaves no history, cache, or cookies
• Session data wiped automatically when you close the tab

• No phone number revealed to the other party
OUTBOUND CALLS (Ultimate)
• Call any US or Canada number from a shared toll-free line
• Your real number stays private
CLOUD BACKUP (Pro)

SECURITY DETAILS
• AES-256 encryption at rest via Android EncryptedSharedPreferences and EncryptedFile
