Your interests, browsing habits, purchases, etc. are still yours, even though you may have also given them to someone else. They're not physical goods. When you 'give them away', you don't lose them. I'm not familiar with every mobile platform's current agreements with its users, but back when I was, most had you agree to a pretty broad policy regarding third-party apps to spare their developers the need to write their own terms of service and privacy policy. That's generally where the consent happens. In the exceptions, the developers do provide terms of service, which you consent to as a condition of installing the app. You almost certainly didn't give your fully informed consent, mind you, unless you enjoy reading legal documents - but that's the current state of the industry both online and off, and in my mind far superior to an extensive batch of lengthy in-your-face disclosures you'd have to agree to before viewing any website. You may disagree, and you may wish that things were different, but that's just how the world works right now.
