Recently me and my family had a huge fight that ended up with my mom asking to check my chat every 20 Minute, she reads every single text that i have sent and to whom did i send it to. (On telegram , Viper , Whatsapp , Messenger)

I want an application whether it's whatsapp or not, this app should contain a virtual side where i have to enter a password if it's wrong it open a virtual screen with virtual chats that i choose how they appear...

Or An application like Virtual Machine on PC, i lock my phone and when i type the password, every password opens for me a different screen with certain apps visible on them( Screen 1, 2 ,3 ) ! no one can view screen 2 apps even on settings, unless he types screen 2 password.
