Chatting with people: I use Facebook Messenger and Whatsapp almost nonstop to chat with my friends. Today too I sent texts, photos and videos. I gave the data of the people I interact with and their numbers to Facebook. They will use this data in ranking the names on my Facebook messenger. They also store the photos and videos I shared with my friends since I can access them on our chat media any time.
I also exchanged emails with the company I’ll be interning with. I gave them data about my work authorization process.
Moving around town: I used my student ID at 11am to get into the gym at Stata Center. I gave my location data to MIT.
Today I got lunch at Cava at 1pm, where I gave my location data to the bank.
Getting online: I ordered stuff on Amazon today at 4pm. I gave my personal data, such as my address, my credit card details and my personal preferences to Amazon (which will be used for their recommender system).
Other things: It’s always funny to see ads on Instagram or Facebook of the brands I currently online shopped from or checked their shopping app on my phone.
Today I was looking at dresses on some brand apps I have on my phone and other apps (such as Facebook and Instagram) got this data of me liking these brands and immediately used it to show me targeted ads.
