When privacy becomes a thing of much importance, you wouldn’t let anyone pry into your devices, be it with or without permission.
Apps are available to enable easy access and provide gamblers with a great degree of comfort that the browser interface might not afford you. Also, some devices come with privacy interface to enable you secure certain apps to note be visible for everyone or anyone with access to your device.
