appbuilder plugin add "PrivacyScreenPlugin"
Both iOS and Android have app switchers which show a screenshot of your app. For most apps this is a nice convenience feature, but if your app displays sensitive information this is a potential privacy risk.
There is nothing to configure but there are some differences between iOS and Android:
In case your splashscreens conform to the defaults - meaning the basename is 'Default' - your splashscreen is shown in the app switcher. If for some reason the plugin can't find your splashscreen it will fall back to blacking out your app.
Bring up the app switcher by pressing the Home button twice.
