MicutVault: Calculator Vault

Hide photos, videos, audio and private notes in a private calculator vault with 9 app disguises, from a working calculator to a clock. Pick one in Settings and MicutVault looks like an ordinary app on your home screen. Everything stays encrypted on your phone, fully offline. No account, no ads, no cloud, no internet permission. 9 DISGUISES — CALCULATOR VAULT & MORE MicutVault installs with its own vault icon. In Settings, switch it to Calculator, Books, Notes, Files, Calendar, Clock, Tasks, Scanner or Recorder, and change it anytime. Each disguise changes the icon and name on your home screen and opens its own realistic screen. • The Calculator really calculates, and your PIN hides in plain sight • In the other disguises, you enter your PIN through ordinary-looking elements • Fingerprint and Forgot PIN open through discreet gestures only you know • Same PIN, same vault, whichever disguise you pick For transparency: Android Settings and Google Play still show the real name, MicutVault. INTRUDER SELFIE — SEE WHO TRIED Optional. MicutVault logs failed PIN attempts and can take one front-camera photo after 5 wrong PINs, stored encrypted inside MicutVault only, never in your gallery. You see a security alert at your next login. Records auto-delete after 30 days. HIDE PHOTOS, VIDEOS, AUDIO & NOTES • Add files with Share from Gallery, Files or your music app, or with the Add button • Files are sorted automatically into categories by their real content, with live counts • MicutVault saves an encrypted copy. The original stays in the source app until you delete it there PRIVATE VIEWER, PLAYER & NOTES • Full-screen photos with zoom, pan and swipe • Slideshow at 3, 5 or 10 seconds • Private audio player with seek and previous/next • Encrypted notes, titles included, saved automatically and searchable • Deleted items wait encrypted in Trash for 30 days CLEAN SHARE — BLUR BEFORE YOU SEND Open a photo, draw boxes over what to hide, then share.

LOCKED TIGHT • PIN, plus optional fingerprint or face unlock. Your PIN always works • Auto-lock after 1, 3 or 5 minutes, or lock instantly. The app always restarts locked • After 5 wrong PINs, entry pauses for 10 minutes to 1 day, your choice. Survives restarts and clock changes • Screenshots, screen recording and Recents previews are blocked on every screen, disguises included • Optional Access Recovery PIN: it can only set a new Primary PIN, never open the vault on its own ENCRYPTED BACKUP & RESTORE Back up anytime to a location you choose, protected by a Backup Recovery Password.
