ELI5: Private Browsing - Does it store the session in RAM and then just purge or does it just retroactively, automatically "delete" the cache from the hard drive like if you pressed "clear history"?

I have always wondered this, if it's the latter case then it's not very secure at all. It would be much more secure if the session is ran from and stored in RAM.

It's private browsing not secure browsing. Your activity can easily be tracked outside the browser. 



It's more like the lock on your bathroom door, it keeps family member accidentally walking in on you but not anyone that is determined to get in.



I would not consider it secure in any way on a public computer.
