Vault is a mobile app that allows users to hide and protect their private photos and videos on their phones. With over 100 million users worldwide, Vault offers features such as App Lock, Private Browser, Cloud Backup, and more for free. Users can import photos and videos into their phones and can only view them after entering the correct password. The app also offers Cloud Backup, which allows users to back up their photos and videos to the cloud for better protection. Additionally, Vault offers a password recovery feature, which allows users to retrieve their password by setting up a security email.

Vault offers advanced features such as Multiple Vault & Fake Vault, which allows users to create multiple vaults with different passwords for storing photos and videos. One of the vaults can also be a fake vault. The app also offers Stealth Mode, which makes the Vault icon disappear from the home screen and can only be found again with the correct password. Vault also offers Break-in Alerts, which secretly snaps a picture of anyone who attempts to access the app with a wrong password. The app captures a photo, the time stamp, and PIN code entered by all intruders.

Users can enter Vault in stealth mode by putting it back on the phone's home screen by adding the Vault widget. Once it appears on the home screen, users can tap on it and input their password to enter. Alternatively, users can download "NQ calculator" in Google Play, open it, and input the correct password, then tap "=". If photos or videos are lost, it may be due to cleaning or free storage apps that automatically delete Vault's data folder used to store pictures and videos. Users can avoid this by not choosing to delete Vault's data folder and subfolders when using such apps. Users can also backup their pictures and videos to the cloud by using the "Cloud Backup" feature in the premium page of Vault.
