About Threema

Threema is a privacy-first Swiss messenger with end-to-end encryption and no phone number requirement. It keeps conversations in one reachable place instead of scattered across inboxes and personal accounts, with search, history and notifications that work across devices. Administrators get the controls they need for members, privacy and retention, while everyday users get a simple interface that needs almost no training to adopt.
