The Cambridge Analytica scandal brought to the fore the huge amount of data that Facebook collects about its users, reports Romain Dillet of TechCrunch. The company has collected data about text messages and phone calls, as well as all phone addresses, which also goes for all messages sent and calls made through its apps. It has used long and wordy terms and conditions to hide how much information it actually stores. Facebook’s payment service notes down credit card numbers and tracks offline purchases thereafter to get data about what users buy. It uses its services to mine every bit of data that it can, which it uses for targeted ads.
While Google and Facebook both have extensive information on all of their users, the former has managed to gather more, argues Jacob Kleinman of Lifehacker. Its search engine gives it a much wider reach than the social media platform has. From what YouTube videos one watches to simple Google searches, it collects every bit of data. Google calendar also gives it access to the events and locations that users go to. Then there is Android; the company keeps records of all call and text message histories through its cellphone platform. Google Maps also gives it an edge over Facebook as it can access where users have been when using the app.
