Open a Private window and browse some websites. Doesn't matter if you login to some websites or not. After you're done quit the browser. Then, when you start Orion again from the scratch and check Preferences - Privacy - Cookies and Site Data - Manage you can still see all the websites' traces so have to delete it manually.
Browsing Privately shouldn't save any site data or at the very least automatically delete it on browser restart
