Safari private browsing behaviour
Hello everyone, I am trying to do a little research on Safari's behaviour while in private browsing mode. I have read that nothing will be saved to the device, is that the case? Or are, for example, thumbnails of videos temporarily stored until safari is closed? Are they stored in RAM or in persistent memory? In case of a professional forensics analysis, could the data be retrieved? Thank You everyone! Also, any other extra info on the security of Safari would be greatly appreciated!
