Calculator Lock - Vault App

🔒 Calculator Lock – Photo Vault, Hide Photos, Videos & Lock Apps

Calculator Lock is a free photo vault, video hider and app locker that looks and works exactly like a normal calculator. Type your secret PIN on the calculator keypad and your private vault opens instantly. To anyone else, it is just a simple calculator.

Hide private photos, videos, documents and notes in a safe, encrypted gallery vault, lock other apps, and find out who tried to snoop on your phone. Calculator Lock is a simple, discreet and secure privacy keeper for everyone.

🧮 REAL WORKING CALCULATOR
Use it for everyday math like any standard calculator app. Enter your secret PIN on the keypad whenever you want to open your hidden vault. Nobody will ever suspect it.

📷 HIDE PHOTOS & VIDEOS
Import photos and videos from your gallery into the vault. Once hidden, they disappear from your regular gallery and are visible only inside Calculator Lock. Keep your private pictures and videos safe from prying eyes.

🖼️ BUILT-IN PHOTO VIEWER & VIDEO PLAYER
View your hidden photos in full screen and play your hidden videos right inside the app. You never need to take your files out of the vault to enjoy them.

📁 HIDE FILES & DOCUMENTS
Store important documents and private files in your secure file locker. Keep ID copies, receipts, bills and personal papers protected behind your calculator lock.

📝 SECRET NOTES
Write private notes, passwords and personal thoughts inside your vault, hidden behind the same calculator password.

🔐 PIN, PATTERN & FINGERPRINT UNLOCK
Choose the unlock method you like best: a secret PIN, a pattern, or biometric fingerprint unlock for fast and secure access.

🎭 DECOY VAULT & FAKE SPACES
Set up a fake PIN that opens a separate decoy vault. If someone forces you to open the app, they will only see the fake space while your real photos and videos stay completely private. Create more than one fake space for extra protection.

🕵️ INTRUDER SELFIE ALERT
When someone enters a wrong PIN, Calculator Lock silently takes a photo with the front camera, with no flash and no sound. Check the intruder log inside your vault to see who tried to get in.

🎨 APP ICON CHANGER (HIDE APP)
Disguise Calculator Lock with a different icon and name: Calculator, Calculator+, Weather, Notes or Clock. Your private space blends in with your other apps and stays hidden.

📱 APP LOCK – LOCK ANY APP
Protect Gallery, WhatsApp, social media, messengers and any other app on your phone with the same PIN, pattern or fingerprint. Stop others from opening your apps and chats.

🗑️ RECYCLE BIN
Deleted a hidden file by mistake? Restore it from the built-in recycle bin.
