Help Collectively…

The Patavinus App helps you in relocating your valuables.

More security with our products

We've tested for you!

How does Patavinus work?

You label your valuables with a supplied QR Code (key tag, sticker, etc.)

When one of your valuables is lost the finder can contact you via a Chat platform. It is completely anonymous without requiring an address or any other personal information. You then can agree on a method of returning the lost item to get it back in the right hands as quickly as possible.

This short, 1-minute animated clip demonstrates how the Patavinus App works.

Try it out!

Then try it out directly - get your mobile phone and scan this code like a finder would:


We've tested for you!

In Nuremberg we've lost 100 keys in February 2019. 70 of which came back within only a few hours. So we've learned: people are awesome and helpful! 

This video is in German, but you can get some impressions of our test.


Furthermore, our CEO Moritz Armbrust explains the idea and how we came up with the idea.
