I launched a private window and typed the address for the first time that evening. The login screen appeared normally. Credentials were accepted and the dashboard loaded with the correct balance. Markets updated at the usual speed. For the full length of the match the private window behaved like an ordinary session.
When I closed the private window at the end of the night every trace of the session disappeared. Reopening a new private window the next evening required a fresh login. No cookies or saved details remained. The complete removal of history was the only lasting difference from a normal browser window.
What the private session still allowed
Deposits and settlements worked without restriction. The transaction history remained visible while the window stayed open. I used match exch 247 for the entire test and found no feature missing. The private mode only affected what survived after the window closed.
A second evening in the same private mode
I repeated the full process the following night. Login, market viewing, and a small test settlement all completed normally. Closing the window again erased the session completely. Two consistent evenings confirmed the behaviour.
Short replies when I described the private window
I mentioned running a full session inside private browsing. Two people answered that they use the same method on shared computers. One said the automatic erasure is the main reason. Another noted that the page loads slightly slower in private mode on older browsers. The comments stayed brief.
One situation that suited the private window
Any evening when the computer might be used by someone else later became the natural time for private mode. The automatic clearing removed the need to log out manually or clear data by hand. On a personal device the ordinary window remained the default.
The private browsing window supported a complete session and then erased every trace when closed. Login, markets, and transactions all functioned normally while the window remained open. Once that limit was clear the private mode became a useful option for specific evenings rather than a regular choice. The match continued to decide when the page needed to open and the window type became a secondary detail.
