Weekly Reflection: Digital Privacy

I went into this class pretty confident I already understood the basics of online privacy. I knew social media tracked you, I knew ads were targeted, and like a lot of people, I had that half-joking belief that my phone was definitely listening to me. What I didn’t expect was to walk away feeling like I actually understood how it all works and honestly, that made it more unsettling, not less.

The short answer to “is my phone listening?” is no. But the real answer is that it doesn’t need to. The class broke down three mechanisms, browser fingerprinting, data brokers, and lookalike modeling, and each one was more eye-opening than the last. The one that stuck with me most was lookalike modeling. The idea that if your friend searches for South Pole flights after spending an afternoon with you, the algorithm assumes you might be interested too, is genuinely eerie. It’s not surveillance in the traditional sense. It’s inference. And in some ways that feels worse, because there’s no single moment where your privacy was “violated” it just quietly erodes through proximity and pattern.

The browser fingerprinting piece was also new to me. I had always assumed incognito mode offered some meaningful protection. Learning that websites can still identify you through your screen resolution, installed fonts, battery level, and time zone, and that combining those creates a signature unique enough to track you across devices, was a real wake-up call. I tried the hands-on activity where you could check your own browser’s fingerprint using the EFF’s Cover Your Tracks tool (https://coveryourtracks.eff.org), and I’d genuinely recommend trying it if you haven’t. Seeing your own results makes it feel a lot more real than reading about it.

What I appreciated about this class was that it didn’t stop at “here’s why you should be scared.” It gave us practical steps: disabling cross-app tracking on your phone, switching to a privacy-focused browser like Firefox or Brave, and even how to opt out of data broker databases. That last one surprised me, I didn’t know that was even an option. It’s time-consuming to do manually, and the paid services that automate it aren’t cheap, which raises a real equity issue. Protecting your privacy, it turns out, is easier if you have time and money. That’s worth sitting with.

The googling yourself in incognito mode activity was unexpectedly thought-provoking too. It reframed privacy not just as something to protect, but as something you can also shape. The idea that a future employer might search your name before an interview, and that your class website could actually function as a portfolio, shifted my thinking. Digital citizenship isn’t only about avoiding harm. It’s about being intentional.

If I had one critique of how this topic gets taught generally, it’s that it often leans too hard into fear without giving people agency. This class struck a better balance. Yes, the surveillance ecosystem is vast and largely invisible. But there are real things you can do, and understanding the mechanics, rather than just accepting “technology is creepy” as a given, makes those choices feel meaningful rather than futile.

Please note that I used Claude (claude.ai) to generate the digital privacy infographic above. The prompt used to generate the infographic was: “Create an infographic summarizing how phones track users without listening, covering browser fingerprinting, data brokers, and lookalike modeling, plus three practical privacy steps, an equity note, and a myth vs. reality section.”
