Only the narrowed claim is defensible, and it carries 'as far as we know': the only identifier-free messenger with a persistent no-install browser client. Do not call the browser client 'full-featured' or say 'no app to install' as if the app were pointless: the browser covers text, photos, files up to about 383 KB and voice calls while the tab is open, runs in one tab at a time, and receives nothing while the tab is closed. The Android and iPhone apps add push notifications, calls that ring when the app is closed, video calls, voice notes, groups, larger files and encrypted backup, and the installed app is the higher-assurance tier. Say 'no install required' or 'nothing to install', and recommend the app for the best experience."
