App functions

Generation of anonymous QR codes
luca takes over the secure transmission of contact data to event organizers and operators of bars, restaurants, or cultural sites. All you share at check-in are QR codes that venue operators can’t associate with you.

Contactless and anonymous data transfer
When guests enter an event or restaurant, they have their anonymous QR code scanned and are thus checked in. The data about your stay is additionally encrypted. The host can’t read this data at any time, which means that you always retain your data sovereignty.

Data release to the health authorities
Only the responsible health authority can read out the relevant encrypted data with a security key – but only if you release your data for the readout.

Check in log view
You can view the history of your check-ins at any time. If the public health department wants to read your data, they need your permission first.

Event-specific functions
For individual events, the app can fulfill additional functions. It can, for example, also become your digital admission ticket.

Automatic deletion of data
Your encrypted data will be automatically deleted at the latest 4 weeks after visiting the event or venue.
