We are not able to publish “adult only” apps in the Google Play Market, therefore they must be installed in a different way. That’s completely safe and very easy.
Download the app to your Android phone and start installation.
The system will notice that your installation is stopped. Tap the “Settings” button in the new window.
Check 'Allow installation from unknown sources'.
Confirm your choice by pressing “OK” in the new window.
Once this is done, tap the “Install” button when it becomes active in bottom right corner.
You will receive a notification about your completed installation and you can now start using Flirtymania+
