Its presets name Macau One Account/DSI, bank KYC, rental agreements, employment, and utility-bill address proof; quality settings are listed at 100%, 80%, and 60%. The site says processing occurs in browser memory and works offline, though that claim is not independently tested by the homepage extract.
