The harvesting of our personal details goes far beyond what many of us could imagine. So I braced myself and had a lookFive things we learned from Mark Zuckerberg’s Facebook hearing
Google knows where you’ve been
Google stores your location (if you have location tracking turned on) every time you turn on your phone. You can see a timeline of where you’ve been from the very first day you started using Google on your phone.
Google knows everything you’ve ever searched – and deleted
Google stores search history across all your devices. That can mean that, even if you delete your search history and phone history on one device, it may still have data saved from other devices.
Google has an advertisement profile of you
Google creates an advertisement profile based on your information, including your location, gender, age, hobbies, career, interests, relationship status, possible weight (need to lose 10lb in one day?) and income.
Google knows all the apps you use
Google stores information on every app and extension you use. They know how often you use them, where you use them, and who you use them to interact with. That means they know who you talk to on Facebook, what countries are you speaking with, what time you go to sleep.
Google has all of your YouTube history
Google stores all of your YouTube history, so they probably know whether you’re going to be a parent soon, if you’re a conservative, if you’re a progressive, if you’re Jewish, Christian, or Muslim, if you’re feeling depressed or suicidal, if you’re anorexic …
The data Google has on you can fill millions of Word documents
Google offers an option to download all of the data it stores about you. This link includes your bookmarks, emails, contacts, your Google Drive files, all of the above information, your YouTube videos, the photos you’ve taken on your phone, the businesses you’ve bought from, the products you’ve bought through Google, data from your calendar, your Google hangout sessions, your location history, the music you listen to, the Google books you’ve purchased, the Google groups you’re in, the websites you’ve created, the phones you’ve owned, the pages you’ve shared, how many steps you walk in a day …
Facebook has reams and reams of data on you, too
Facebook offers a similar option to download all your information. This includes every message you’ve ever sent or been sent, every file you’ve ever sent or been sent, all the contacts in your phone, and all the audio messages you’ve ever sent or been sent.
Facebook stores everything from your stickers to your login location
Facebook also stores what it thinks you might be interested in based off the things you’ve liked and what you and your friends talk about (I apparently like the topic “girl”).
They can access your webcam and microphone
The data they collect includes tracking where you are, what applications you have installed, when you use them, what you use them for, access to your webcam and microphone at any time, your contacts, your emails, your calendar, your call history, the messages you send and receive, the files you download, the games you play, your photos and videos, your music, your search history, your browsing history, even what radio stations you listen to.
