Unlike many other similar apps that only import your photos into a folder, they are only hidden, not encrypted, so your photos still can be accessed by using some other tools like iExplorer or iTools. FireLock always encrypts your data, so they will never be able to access without your password.
Absolutely safe.
FireLock was optimized for iOS 10 and above
This is why you should use FireLock to protect your photos/videos. Everyone could use iExplorer to browse your data. FireLock always encrypts your photos/videos, so they are unreadable.
