A free program for Android, by Hendrik Schiffer.
ScreenWings: Anti-Screenshot is a powerful Android tool that will block screenshots and photos from being saved to your device. The application will not allow screenshots or photos to be saved in the device's gallery, so even if you try to take a screenshot or upload a photo to your social media accounts, it will not be saved. This will give you the ability to have complete control over your device and data.
This application requires the permission to draw over other apps. If you want to enable or disable it for a particular application, you can go to the application's settings.
