Hide Pictures Gallery Vault is the best way to protect your photos from intruders and nosy friends and family members. The app hides pictures and videos by encrypting them with a PIN, pattern, or fingerprint and then stores the secure files in a separate gallery vault. You can even create multiple gallery vaults and encrypt your photos and videos within a vault.
When you install the app, it will ask you to set a PIN, pattern, or fingerprint. Once you set the password, the app will start hiding your photos and videos. To view your files, you must enter the correct PIN, pattern, or fingerprint.
