From the options menu in TeraBox, you can turn on or off an option that comes turned on by default if you want to automatically protect all the photos on your device. You can also choose to do the same with your videos, although this option is only available to Premium subscribers. Of course, you can also choose files or folders to protect them all instantly and always have them available in the cloud.
Apart from all the content you store in the cloud, you can create a virtual box on your own device. To be able to access this virtual safe, you will need a PIN, that you create the first time you open the app. Everything you add to your safe space will stay in your safe space. So, only you (or anyone you tell your PIN to) can take a look at the most sensitive content on your device.
TeraBox is a good cloud-storage app, thanks to which you can have a complete backup of all the information on your Android. With this app installed, you won't have to worry about losing a photo or video ever again.
