Description
NOTE: A Threema Shop license is required, please visit: https://shop.threema.ch to get one.
Threema is the world’s best-selling secure messenger, used by more than 12 million people in over 175 countries, developed in Switzerland, and designed with privacy and data protection in mind. Whether chats, calls, or files, everything is end-to-end encrypted, and no data trail is left behind. Instead of a phone number or email address, a randomly generated Threema ID serves as a unique identifier – anonymous and secure. Threema protects what really matters: your privacy.
In contrast to the version distributed via Google Play, Threema Libre contains no proprietary libraries / components (like Google Play Services).
Advantages of Threema:
• Text and voice messages, including emoji reactions
• End-to-end encrypted voice, video, and group calls
• Location sharing
• Sending files in all formats (PDF, GIF, MP3, ZIP, and more)
• Ability to edit sent messages and delete them for chat partners
• Desktop app and web client for convenient chatting on your PC
• Group creation and polls
• Light or dark mode
• No ads, no trackers, no data collection
• Identity verification of contacts by scanning their QR code
Reliable security:
• Open source and regular audits
• Servers in Switzerland
• Anonymous use possible: no phone number or email address required
• Messages are deleted from the server immediately after delivery
