About

CalcPro

Features
Read full description

CalcPro is a truly encrypted photo and video vault disguised as a calculator. It opens as a fully working scientific calculator. Type your PIN and press = to open your vault. Anyone who picks up your phone just sees a calculator. REAL ENCRYPTION • Files are encrypted on your device with AES-256. Your PIN is never stored. • Many "secret vault" apps only hide files; CalcPro encrypts them. ALBUMS • Sort photos, videos, documents and audio into albums. • Select several files and move them in one tap. DON'T LOSE IT WHEN YOU CHANGE PHONES • Optionally move your encrypted vault to a new iPhone with iCloud Backup — it opens with the same PIN. • Or keep it on this device only and export a password-protected encrypted backup. • The app reminds you when your backup gets old. PROTECTION UNDER PRESSURE • Decoy PIN: opens a separate, simple vault; your real data is cryptographically apart. A REAL CALCULATOR • Scientific, programmer, graphing, matrices, derivatives/integrals, statistics. • Unit, currency, VAT, discount, interest and number-system converters. MORE • Secret notes and private contacts • Face ID / Touch ID • Elite (one-time purchase): no ads, intruder selfie, screenshot protection, panic mode, auto-lock options. Privacy: no account, no servers of ours. Your vault is encrypted and opens only with your PIN.
