What is an APK File?
An Android Package Kit (APK) is the package file format used by the Android operating system to distribute and install mobile apps.
Just like Windows (PC) systems use a .exe file, or macOS (Mac) use a .dmg file for installing software, the APK does the same for Android.
When you download an APK online, you're getting an app. Unfortunately, most users get apps from the Google Play Store without seeing the word APK.
When you purchase our Android apps on the official Protectstar online shop, you get an email with your activation code and a download link to an APK file.
