Upfront disclosure

When an application is installed or enabled, it should inform you of its principal and significant functions. And if the application makes money by showing you advertising, it should clearly and conspicuously explain this. This information should be presented in a way that a typical user will see and understand – not buried in small print that requires you to scroll. For example, if the application is paid for by serving pop-up ads or sending your personal data to a third party, that should be made clear to you.
