It hides photos and videos, but not the app file because I cannot afford premium nor having the money to hide the app so that no one can see it and ask for reasons.

What is an APK file?

An APK file is an app created for Android, Google's mobile operating system. Some apps come pre-installed on Android devices, while other apps can be downloaded from Google Play, or site like . Apps downloaded from Google Play are automatically installed on your device, while those downloaded from other sources must be installed manually.

If I install an APK from this website, will I be able to update the app from the Play Store?

Yes, absolutely. As soon as the Play Store finds a version of the app newer than the one you've installed, it will commence an update.

What measures do you take to make sure all APKs are real?

Whenever someone wants to download an APK file from this site, 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.

Why can't I press the Install button? It's grayed out on my Android device!

Disable any screen-dimming apps, like Lux or Twilight. For security reasons, Android will gray out the Install button when an app like that is active.
