Today, Threema’s web client enters the closed beta stage (limited to existing testers), and it will soon be available to all Android users. Support for other platforms will follow at a later date.
Threema Web connects browser and app via the shortest path using SaltyRTC. Our technical approach provides highest security and maximum data restraint. More detailed information will be available soon.
The public release of Threema Web is scheduled for early 2017. We will let you know as soon as the beta phase has been completed. Stay tuned!
