About this app

Yivi is an app that lets you easily and securely log in, share data and prove who you are. Without sharing too much about yourself. With Yivi, you take control of your data. You always see what an organisation wants to know about you and you decide whether to share that data. Your data is only stored on your mobile, safely behind a PIN code. No one is watching, not even Yivi. That's how safe it is.

Yivi is being developed by the Caesar Groep, and is based on work by the Privacy By Design Foundation. Previously known as “IRMA” the Yivi ID wallet is fully open-source.
