About Yivi

Yivi stands for ‘Your digital life’ and you pronounce it as Yivi.

There are two organisations behind Yivi that closely collaborate for Yivi adoption:. The Privacy by Design Foundation owns the Yivi brand rights. The Dutch company Caesar Groep is responsible for the further development and management of Yivi. The cooperation guarantees, by contract, the privacy-friendly character of the Yivi app, the opnness of its source code, the free use for end-users, and the proper, secure working.

The development of Yivi

The Yivi app is the successor to the IRMA app, the first privacy-friendly digital wallet based on personal attributes. IRMA (renamed to Yivi) was developed by Bart Jacobs with his team at Radboud University in Nijmegen. Jacobs is also chairman of the Privacy by Design Foundation. In 2019, collaboration with SIDN began, with SIDN taking over responsibility for managing IRMA’s backbone, to ensure the technology’s essential continuity and availability. Since the fall of 2024 the Dutch company Caesar Groep takes over from SIDN the further development and management of Yivi, in close cooperation with the Privacy by Design Foundation.

Our mission statement

Internet users are asked to share privacy-sensitive data too often and often share more information than necessary. This can and should be done differently. We believe that developing simple, privacy-friendly and secure solutions for online identification contributes to the protection of privacy and identity and optimal use of the Internet. And thus contribute to our mission for a promising and carefree digital existence for everyone.
