For individuals to feel comfortable sharing their personal information on the internet, there should be some sort of legal responsibility on businesses to protect that data and keep the users informed about the status and health of their information. Countries around the world have realized the need to protect their citizens' data and privacy. Businesses and websites that collect and/or process customer information are required to publish and abide by a Privacy Policy agreement. A majority of countries have already enacted laws to protect their users' data security and privacy. These laws require businesses to obtain explicit consent from users whose data they will store or process.

Apart from governing laws, some websites like Apple, Amazon, and Google require website and app owners to post a Privacy Policy agreement if they use any of their services. Many websites and apps use in-page/in-app advertising by third parties to generate revenue. As these ads also collect user data, third parties require the websites or apps to ask their users' permission for sharing their personal data.
