## What is CalcPro?

Calculator Vault looks and works like a normal calculator. Inside is an encrypted vault for your photos and videos.

Anyone who opens the app sees a working calculator. Type your PIN and press = to open your vault.

REALLY ENCRYPTED
• Files are encrypted on your iPhone with AES-256.
• Your PIN is never stored. No account to create, no servers of ours.

PHOTOS, VIDEOS AND FILES
• Hide photos, videos, documents and audio.
• Sort them into albums and move several files at once.
• Private notes and private contacts.

DECOY PIN
• Set up to two decoy PINs.
• If someone forces you to open the app, a separate, plain vault opens instead.

KEEP IT WHEN YOU CHANGE PHONES
• Move your encrypted vault to a new iPhone with iCloud Backup. It opens with the same PIN.
• Or keep it on this iPhone only and export a password-protected backup file.

A REAL CALCULATOR
• Scientific: trig, logs, powers, factorial, memory keys.
• Graphing, equation solver (complex roots too), matrices, derivatives and integrals.
• Statistics, programmer mode, number systems.
• Currency, loan, VAT, discount, percent, tip, unit price, dates and BMI.
• Length, mass, area, volume, speed, time, data and temperature converters.

MORE
• Face ID / Touch ID
• Elite (one-time purchase): no ads, intruder photo, screenshot protection, panic mode, auto-lock options.

Privacy: no account, no servers of ours. Your vault opens only with your PIN.
