According to StockApps.com, Apple "is the most privacy-conscious firm out there."
"Apple only stores the information that is necessary to maintain users' accounts," it continues. "This is because their website is not as reliant on advertising revenue as are Google, Twitter, and Facebook."
The StockApps.com report does not list what it describes as the "data points" that Big Tech firms collect for every user. However, it says they include location details, browser history, activity on third-party websites, and in Google's case, also emails in Gmail.
It also doesn't detail its methodology but does say that it used the marketing firm's digital information world to investigate Apple, Amazon, Facebook, Google, and Twitter.
Of these five, Google reportedly tracks 39 separate data points per user, while Apple tracks only 12. Unexpectedly, Facebook is stated as tracking only 14 data points, while Amazon tracks 23, and Twitter tracks 24.
Separately, the Australian government recently fined Google $40 million over location tracking on Android.
