Calculator Vault & Locker

Fexo brings you a calculator that guards your most private moments. It looks and works like an ordinary calculator — but type your secret PIN and press "=" to open a fully encrypted vault only you can reach. Anyone who picks up your phone just sees a working calculator. Your photos, videos, files, notes, contacts, and audio stay locked behind military-grade AES-256 encryption, stored only on your device and never uploaded anywhere. Fexo Calculator Vault is built for real privacy. Move sensitive photos and videos out of your Photos library and into the vault, unlock instantly with Face ID or Touch ID, and set a decoy PIN that opens a harmless second vault if someone pressures you to unlock the app. KEY FEATURES Working calculator that hides a PIN-protected vault behind "=" Decoy PIN opens a separate, harmless vault under pressure Face ID and Touch ID unlock AES-256 on-device encryption with Argon2id and iOS Keychain keys Six vaults: photos, videos, files, notes, contacts, and audio Move photos and videos out of Photos and delete the originals Restore items back to Photos or to the Files app anytime Secret camera and voice recorder save straight into the vault Built-in photo, video, audio, and PDF viewers Albums, favorites, search, sort, and batch operations Intruder selfie captures anyone who enters the wrong PIN Screenshot and screen-recording detection with a security log Auto-lock, lockout, shake-to-lock panic gesture, and App Switcher privacy overlay Encrypted local backup you can restore on a fresh install Why choose Fexo: everything runs fully offline, so your private data never leaves your device.
