About Threema
Threema is a Swiss encrypted messaging platform protecting all communications with end-to-end encryption across messages, calls, group chats, and file transfers, while uniquely requiring no phone number or email address. Every user receives a random Threema ID, enabling communication without ever linking identity to a device or personal data.
Designed for personal and professional use, Threema Work adds enterprise management features including user provisioning and MDM integration, while Threema OnPrem lets organisations host the entire server infrastructure on their own premises. Open-source clients and reproducible builds allow independent verification of all security claims.
Key benefits:
- No phone number required, as users communicate via a random Threema ID with no personal data
- E2E encryption for all messages, voice and video calls, group chats, and files
- Minimal metadata, with messages deleted from servers after delivery and contacts kept on-device
- Threema Work with MDM integration and admin controls for enterprise deployment
- Threema OnPrem for full self-hosted deployment with zero cloud dependency
- Open-source clients with reproducible builds for independent security auditing
- ISO 27001 certified and compliant with GDPR and Swiss data protection law
Operated by Threema GmbH, headquartered in Pfäffikon, Switzerland, with all servers located in Switzerland under Swiss data protection law, one of the world's strongest privacy frameworks. The company holds ISO 27001 certification, has no ties to advertising networks, and complies fully with GDPR.
Trusted by 12 million+ users and 8,000+ organisations including Mercedes-Benz, EDEKA, the Frankfurt City Government, the Swiss Army, and the German Federal Bank.
Why choose Threema over Telegram?
The decisive argument is data jurisdiction. Telegram is headquartered in the United Arab Emirates, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Threema removes that overhead. As a Switzerland-based provider, it operates under Swiss FADP + GDPR for EU users, and data stays in Switzerland, which the European Commission recognises as offering an adequate level of protection. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
