Where copies are recorded

Settings, Clips has two site lists, the same shape as the expansion lists under Settings, Snippets. Never on these sites leaves those hosts and everything under them alone, so what you copy in your bank or your mail stays out of Clips. Only on these sites does the opposite: once it has anything in it, copies are recorded nowhere else. Type a site as you would read it in the address bar; example.com covers mail.example.com too. Passwords are never recorded, whatever the lists say.
