Threema is the messenger people choose when privacy is the whole point: no phone number required, end-to-end encryption by default, and your data tied to a device rather than a profile in the cloud. On a computer that privacy-first design means Threema Web links to the app on your phone, and it works best when it has a stable, dedicated home instead of a browser tab you keep losing. Franz gives Threema that home as a focused service tab in your sidebar, alongside the rest of your conversations.
Threema Web, linked to your phone
Franz loads the full web.threema.ch client, so you connect Threema the way it is designed to be connected: open the Threema tab in Franz, link it from the app on your phone, and your chats appear with the same end-to-end encryption you rely on. Your messages stay between your devices, and Franz simply hosts the official web session in a dedicated tab. Group chats, media, and your conversation list all work exactly as they do on the official client, because it is the official client, wrapped as a desktop app you can pin and return to without re-finding a browser window.
Private messages, surfaced on the desktop
Privacy should not mean missing the message. Franz gives Threema native desktop notifications with the notification sound, so a new message reaches you right away instead of waiting silently in a background tab. The unread badge on the Threema service shows how many conversations are waiting at a glance, and because Threema runs as its own tab it keeps notifying you while you work in another service, without you leaving the encrypted session open in a stray browser window.
Threema beside your other chats
Franz is a native desktop app for macOS, Windows, and Linux, so Threema works the same wherever you are, with a real dock or taskbar presence and a keyboard shortcut to your other services. Instead of treating your most private messenger as a tab you keep separate and keep losing, you give Threema a dependable place in the same window as the rest of your day.
