An Xposed Module to Enable
FLAG_SECURE, disabling screenshots and recording absolutely everywhere.
This will give you the absolute privacy, as absolutely nothing is able to record or screenshot anything.
This app does prevent apps from detecting that you've taken a screenshot or recorded it like Snapchat or Instagram, because you literally cannot take screenshots anymore. This disables it in all apps you select. So you can't screenshot your girlfriend's nudes. (But that probably does not matter since you're reading this anyway)
