The problem ZK Tik Tak solves

In today's world, protecting personal data and privacy is not always associated with a pleasant experience. My application has two important functions.
The first is to show that data protection is not only about routine things, but also about something exciting. It is a game that is easy to remember and easy to share with friends.
The second is to popularize knowledge about privacy and security. Gamification is a wonderful and familiar tool for people that reduces barriers to learning something new. In this way, we will ensure the adoption of tools dedicated to security and privacy.

second project is for Horizen
Idea - app allows to verify the votes.
Optionally I wanted add the ZKpassport integration to check the data.

Challenges I ran into

I encountered a problem with scanning QR codes, which I solved with the wonderful people from the ZKpassport team. It was my first time using the backend, and in general, it was my first time making an app, because this was my first participation in a hackathon.
