The app is designed for both private users and businesses, offering specialized solutions such as Threema Work and Threema OnPrem, tailored to the needs of corporate clients.

The Company Behind Threema

Threema GmbH was founded in Switzerland, a country known for its stringent privacy laws. This gives Threema a significant advantage in terms of compliance with the General Data Protection Regulation (GDPR) and the protection of user data. Threema's company philosophy is based on the zero-knowledge principle, ensuring that neither third parties nor the provider itself have access to communication content.

Threema is an independent company, not subject to the influence of large technology corporations or ad networks. The development and maintenance of the app take place entirely in Switzerland, with the source code being open source. This allows external security experts to verify the app's integrity, further enhancing trust in the platform.
