Capacitor Privacy Screen Plugin
Introduction
⚡️ Capacitor plugin that protects your app from displaying a screenshot in Recents screen/App Switcher.
On Android, this plugin sets the FLAG_SECURE flag to treat the content of the window as secure, preventing it from appearing in screenshots or from being viewed on non-secure displays.
On iOS, this plugin hides the webview window when the app is no longer active and loses focus (UIApplicationWillResignActiveNotification) so that a gray screen is shown instead. It also prevents screenshots (a black screen will be captured).
Using the Camera Plugin
Disabling screenshots can interfere with plugins that hide the WebView like the Camera plugin. To avoid issues call disable
before using a plugin and then enable
after you are finished.

Usage
The plugin only needs to be installed. The protection is enabled by default.
However, you have the option to enable/disable the protection:
import { PrivacyScreen } from '@capacitor-community/privacy-screen';
const enable = async () => {
await PrivacyScreen.enable();
};
const disable = async () => {
await PrivacyScreen.disable();
};
