Secret Vault - Lock Photos is the best and most private photo and video app for iPhone. It allows you to lock and manage your private photos, videos, and other files with ease. With multiple security mechanisms, Secret Vault ensures that your privacy remains protected from prying eyes.

This app offers basic functions such as a simple interface, easy PIN code access, fast iTunes File Sharing Sync, and easy Wi-Fi transmission. You can import photos from the Photo App (Camera Roll) and even use the in-app camera to capture new photos.

In terms of security, Secret Vault requires a PIN code to access your photo and video privacy. It also has a fake PIN feature that creates a decoy Secret Vault with a separate PIN code. Additionally, there is a hidden feature that allows you to make files and folders invisible.

Secret Vault offers more than just photo and video protection. It allows you to save special memories, family photos, and important documents. You can also protect copies of your driver's license, ID cards, and credit cards.

The app provides additional protections to keep people away from your private albums and offers features like PIN code lock, Touch ID or Face ID, and the ability to export photos/videos to the iOS photo album or to your computer. It also supports Wi-Fi web access for downloading and uploading files.

Secret Vault even includes an in-app photo editor with special effects filters and stickers. It supports Live Photos and allows you to sync and backup with OneDrive, Google Drive, and Dropbox.

It's important to note that all your photos stored in Secret Vault are 100% private and are only saved on your device, never uploaded to servers.
