About Photo Vault

Protect your private photos and videos with Photo Vault – the secure gallery app disguised as a fully working calculator.

Enter your secret PIN directly into the calculator interface to unlock your personal vault instantly. AES encryption shields every photo and video inside the vault, keeping files invisible to your gallery and inaccessible without your credentials.

🔒 CALCULATOR DISGUISE LOCK

Your vault lives behind a real, working calculator. Type any number, tap the hidden PIN sequence, and your private gallery opens. Nobody looking at your screen suspects a photo vault exists.

📸 PHOTO & VIDEO VAULT

Import photos and videos from your gallery with a single tap. Encrypted thumbnails let you browse your private collection inside the vault without exposing files to other apps or the system gallery.

🛡️ BIOMETRIC AUTHENTICATION

Unlock your secure vault with fingerprint recognition or face authentication for fast, effortless access to your hidden photos and videos.

🕵️ INTRUDER DETECTION & SELFIE TRAP

Photo Vault captures a photo of anyone who enters the wrong PIN and logs every intrusion attempt with a timestamp. Return to your intruder log and see exactly who tried to access your private files.

👻 GUEST MODE – DECOY VAULT

Assign a secondary PIN that opens a decoy vault showing nothing. If anyone demands access, show them an empty gallery while your real photos and videos stay hidden.

🗂️ ALBUM ORGANIZATION

Create private albums to organize your hidden photos and videos by date, event, or category. Keep your vault tidy and easy to navigate.

🔐 AES ENCRYPTION ENGINE

Every file in the vault is protected by AES-grade encryption. Photos and videos are stored as unreadable encrypted data – completely inaccessible outside the built-in viewer.

📥 BUILT-IN MEDIA VIEWER

View decrypted photos and watch videos directly inside Photo Vault. No file ever leaves the vault unprotected or appears in your standard gallery.

Photo Vault gives you complete control over your personal gallery. Whether you share your device with family, friends, or colleagues, your private photos and videos remain locked and hidden.

Keep what is yours, yours.
