Vaulty is a popular photo vault and album locker app for Android that allows users to keep their private pictures and videos hidden behind a PIN. The app is easy to use and can secretly hide photos, videos, and other files without anyone knowing. Users can hide pictures and videos within Vaulty by tapping the lock icon at the top, selecting an album, and tapping thumbnails to select files. They can also share pictures and videos from other apps by tapping the share icon, selecting Vaulty from the list of apps, and hiding them safely in their vault.

Vaulty offers several features to keep users' private data secure. Users can PIN protect their photo gallery, disguise Vaulty as a fully functional calculator or stocks lookup app, and use biometric login to quickly unlock their private vault with just their fingerprint or face on supported devices. The app also offers free, automatic, online backup to save users' secret media regardless of whether their phone is broken or lost. Users can store and organize important documents, protect copies of their driver's license, ID cards, and credit cards, and create a decoy Vaulty vault with a separate PIN to keep different vaults to show different people.

Vaulty also offers an intruder alert feature that will secretly take a photo whenever a wrong password is entered for the app. This will allow users to see anyone who may be snooping on their personal pics. The app can play any video the device can handle, and if there's a format the phone can't handle natively, Vaulty can securely display the video in third-party apps. Simply glance through the phone's photo gallery and tap the lock icon at the top of photos or videos to bring them into Vaulty. Once imported, Vaulty effortlessly erases those photographs from the phone's photo gallery while users can still view them in Vaulty.

Overall, Vaulty is a reliable and secure app that helps users safeguard their significant data. The app focuses on creating an easy-to-use secure app that improves users' virtual life.
