When you use voice recognition on your phone or tablet, your voice is carried to Apple or Google or whomever you use so it can be analyzed. That's how your "smart" phone figures out what you said, so it knows what to do. Whenever you use most apps that need your microphone or camera to work, your mic or camera data is sent to some company's server where it is, at least temporarily, stored as a file. You gave them permission to do that when you clicked "I agree."
That's bad enough. But here's the real kicker: if you read the privacy policies of those companies, you'll see that each company has "trusted partners" with whom they share information "from time to time." And if you read the privacy policy of those "trusted partners" (good luck finding out who the trusted partners are), you'll see that each partner has their own "trusted partners" that they share data with from time to time. And that second level of trusted partners shares data with a third level of partners, and on and on. If you worked at it full-time for a month, you couldn't track down all the "trusted partners" and figure out what they have legal access to.
When you clicked "I agree," you gave thousands of organizations explicit permission to watch and listen through the device you keep with you all day and all night.
