Illegal graffiti is vandalism. Removing it is expensive —and it makes us feel unsafe in our own cities.


Let's free up that money for important stuff.


You can help by taking photos of illegal graffiti, both tags* and pieces* and uploading them to the GrattitiTagr-app.


We collect and process the data for use preventively, in cooperation with the authorities and private companies.


Doing this benefits you, your city and our country.


Download the app and get started in 2 minutes.

* A tag is the graffiti painter's name or initials, a piece is a larger picture, eg painted on an subway train or a wall.



Not with our good will!

With the GraffitiTagr app, you help create the world's first structured collection of data and knowledge about illegal graffiti in Denmark.



In fact, you are making history!


Your photos, together with the many other photos we gather, collectively form an overall picture of the illegal graffiti in Denmark.


Like when you do a jigsaw puzzle. Piece by piece. Photo by photo.



Based on the information in your photos, and with the help of advanced technology, we can analyze the patterns and gain important knowledge.


Valuable knowledge that can be used by the authorities to prevent graffiti.


And free up the money spent on things that are important.


Some call it street art. Others call it a bit of fun.


Most call it vandalism.

We call it a waste of money. Lots of money!

Each year, United States spends around $ 20 billion fighting illegal graffiti and removing it from public buildings, trains, statues, murals, road signs, private homes…

That money could be better spent on the important things that benefit us all.

And the world would look prettier.

The graffiti initials you see everywhere are called "tags". But "tagging" is also English for putting a label onto something.


Hence, GraffitiTagr.

Why is graffiti a problem?

Each year, The United States spends around $ 20 billion fighting illegal graffiti and removing it from public buildings, trains, statues, murals, road signs, private homes…

That money could be better spent on the important things that benefit us all.

Who can use the app?

Everyone can, and everyone should. Adults, teenagers, children, grandparents, parents and grandchildren. Dog walkers, couriers, joggers and new moms taking their babies out in a stroller :-)

Are you monitoring my movements?

No. The photos you upload are a piece of a larger puzzle. Other users in the app can see what you uploaded but not that you uploaded. In the same way, you can see what others have uploaded but not who uploaded. The app doesn’t track you. Only when you upload a photo will it record your location.

This is how we use your observations

GraffitiTagr is not just an app. It is just the tip of the iceberg. Below the surface, using some heavy artillery in the form of big data, artificial intelligence, and advanced image recognition, every photo uploaded is analyzed. This artillery studies the patterns, trends, and contexts of the illegal graffiti. We process this information and use it preventively, in cooperation with the authorities and private companies.

What about GDPR?

Of course, we comply with the EU's GDPR data protection law. Read more in our Privacy Policy and Terms and Conditions.
