KeepSafe is a popular solution for keeping photos and videos safe against other people that might get access to your Android smartphone or tablet. After you install and launch this app, you will be prompted inside the window to create a password. Everything that you place inside this application will be protected by military-grade encryption. You can create vaults, add your photos and videos and then configure a fingerprint authentication or PIN code.
The fingerprint option works only on devices that have such technology built-in. After you add important items inside this app, you can remove them from your phone and only access them here. Another feature is the ability to backup videos and photos and you no longer have to worry about your smartphone being stolen, damaged or lost. The face-down automatic locking function will detect when your device is facing downwards and the lock is quickly triggered.
You can share your sensitive photos with other people and you have control over how long the receiver is able to see that content before it gets deleted. To protect itself, this application doesn't show up inside your recently used apps list. Moreover, the included private cloud is capable of synchronization of your videos and photos and you can use them across multiple devices.
