Threema

Threema is a secure messaging application developed in Switzerland, designed for businesses and individuals who require high levels of privacy and data protection. It provides a reliable alternative to mainstream messengers by building its service around strict Swiss data protection laws and full GDPR compliance. Your communication, including messages, calls, and files, is kept confidential.

The platform is built on several core principles for data security:

• Swiss Data Sovereignty: Developed and hosted exclusively in Switzerland, your data is protected by some of the world's strongest privacy regulations.
• Consistent End-to-End Encryption: All communication is encrypted from sender to receiver using the open-source NaCl cryptography library. No one else, not even Threema, can access the content.
• Anonymous Communication: You can use the app without linking a phone number or email address, protecting your identity and contact network.
• Minimal Metadata Collection: The system is designed to generate as little data as technically possible. Messages are deleted from servers immediately after delivery.

For organizations, Threema Work offers a management console for user administration, while Threema OnPrem allows you to host the messenger on your own servers for complete data control. This makes it a suitable tool for companies in regulated industries or those handling sensitive information.
