Suppose you visit any website or you download any mobile app and after that, you're entering data like your name, email, phone, address, and many other details.
After you have submitted your details on any particular website or app what the website or app owner is going to do with your data? Will they use it for their purposes like developing their services or they are sharing your data with other companies or users?
After that, you'll have to select many choices from different questions like whether your app or website uses Google Analytics, and what type of data you're collecting from users. What are you doing with that data whether you're using it for remarketing or not etc.?
