Q: What is an APK File?

A: An Android Package Kit (APK for short) is the package file format used by the Android operating system for distribution and installation of mobile applications. Just like Windows (PC) systems use an .exe file for installing software, Android does the same.

Q: Why CloudApks.com can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from CloudApks.com, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: If I install an APK from CloudApks.com, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like CloudApks.com goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: What are Android Application permissions?

A: Applications require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
