## What is CalcPro?

CalcPro combines a private encrypted vault with a powerful scientific calculator.

Protect photos, videos, documents, private notes and contacts behind a PIN-secured vault. Handle everyday calculations and advanced mathematics in the same app.

PRIVATE VAULT

• Import photos, videos and documents into a protected space
• Create private notes and contacts
• Manage deleted items with the vault trash
• Create and restore password-protected encrypted backups
• Open a cryptographically separate decoy vault with a decoy PIN
• Return to the calculator instantly
• Use optional Face ID or Touch ID unlock
• Enable an optional intruder selfie after failed PIN attempts

STRONG ON-DEVICE PROTECTION

Vault content is encrypted on your device with AES-256-GCM. PIN-based keys are derived with PBKDF2. Your vault files, notes and contacts are not uploaded to the cloud. If you lose your PIN, nobody, including the developer, can unlock your vault.

SCIENTIFIC CALCULATOR

• Standard calculations and calculation history
• Trigonometric and inverse trigonometric functions
• Logarithms, exponentials, square root and cube root
• Hyperbolic functions, percentages and rounding
• Graphing, derivatives and integral tools
• Matrix and vector calculations
• Linear systems, GCD, LCM and prime number tools
• Unit, date, discount, finance and numeral-system converters

BUILT FOR LARGE FILES

Photos and videos are processed as files. Encrypted backup and restore streams large content in chunks and validates data integrity instead of loading the entire file into memory.

The free version contains ads and applies a vault upload limit. The one-time Elite Vault in-app purchase removes ads and unlocks unlimited uploads.

Your vault content belongs to you and stays on your device.
