Tech giant Google collects the most data among all the big tech companies, including Twitter, Apple, Amazon, and Facebook, said a report published by StockApps.com on Monday. According to the analysis, out of the five major digital firms, Google harvests the most data on its users by tracking 39 types of private data for each user.

"Most people do not have the time or patience to read privacy policies that can be several pages long for each website they visit. Also, it is quite unlikely that all users have a background in law to properly grasp the privacy policy," Edith Reads from StockApps.com said in a statement.
