All your data is being collected and automatically analysed by the 14 eyes. If you want to obfuscate that you can and you can go to ever greater and greater lengths to achieve that. But for most people they are just un-retrieved data in the worlds largest data set. If you become of interest, even Tor can't stop a co-ordinated surveillance. Like most security (physical and digital) the rabbit hole is infinite and it's best to balance usability with security. You could secure your home with 20 locks on your front door every time you leave home and while that would give you more protection than one simple Yale lock, it doesn't stop a determined intruder, but it does make it extremely difficult for you to come and go from your house. Understanding Internet security can be deeply interesting, but, if you are simply worried about being tracked and logged, don't be, you are tracked and logged as is everybody. By increasing your security, you're just making your neighbour an easier target than you.
