Use Screen Security to prevent CoolApp previews from appearing in the app switcher on your phone. This is unrelated to the screen lock designed to lock your CoolApp screen so that you can’t interact with the app.

How do I enable or disable Screen Security?
In CoolApp, tap your profile  > Settings (iOS) > Privacy > Screen Security (Android) or Hide Screen in App Switcher (iOS)

• To enable, tap the slider so it is blue.
• To disable, tap the slider so it is grey.

When enabled,

• A blue privacy screen with the CoolApp logo will appear to cover your CoolApp text.
• On Android, this will also prevent screenshots of CoolApp on your own Android device.
