Unlike other browser apps like Chrome or Brave, Safari does not fully close your Private tabs when you exit the program on iOS. This implies that if you shut the Safari app by swiping it off the Recent Apps screen, the open private tabs before quitting the program will reappear the next time you reopen Safari on your iPhone.
This might lead to uncomfortable circumstances if you forget to exit Private mode during your previous browsing session, as reopening Safari brings up all the web pages you may have opened as private tabs.
When you close the Chrome or Brave app while private browsing, all private tabs are permanently closed, and there is no way to recover them. This way, your secret browsing sessions will remain anonymous even if you forget to shut down any active tabs.
Unfortunately, Safari on iOS lacks this capability. So, the only practical method to avoid future embarrassment is to turn off private browsing manually every time you’re done perusing the web anonymously on Safari.
