I recently opened an occasionally-used news app on my smartphone. A notice appeared about the use of cookies by the app. Long legal explanations and disclaimers. A request to accept before going on. However, there was no ability to decline permission. I tried to get around the notice without consenting, but could not.
I thought about all of the warnings about tracking personal data. I considered that my personal data must be followed by other apps. I debated whether I really needed this particular news app.
I closed the app without consenting.
