Audio Manager Vault is a free Android app developed by WR Infosoft that allows you to hide your photos, videos, and audios from your gallery behind a secure vault. The app features a secret lock that can only be accessed with the correct passcode or fingerprint (if supported by your device). Additionally, you can create secure notes inside the vault that can only be accessed by entering the correct passcode.

One of the most notable features of Audio Manager Vault is the ability to hide your MP3 files inside the vault. This can be useful if you want to keep your audio files private or away from prying eyes. The app also lets you share hidden files from the vault with security, ensuring that your files remain safe and secure even when you share them with others.

Other features of Audio Manager Vault include an image slideshow with custom duration, fingerprint unlock (if supported by your device), fake passcode that displays an empty vault, and passcode recovery in case you forget your passcode.
