Essential cookie
twiggy_session keeps you signed in, for up to 30 days. It is set when you open a sign-in link, can't be read by page scripts, and is needed for the app to work.
Browser storage (preferences)
Your browser also remembers a few things for your convenience: view settings (panels, levels shown, compact mode), the AI assistance setting, recent sign-off addresses, and feedback you haven't sent yet. This stays on your device and is never sent to us. You can clear it with Cookie settings at the bottom of the sign-in page, or in your browser.
