About DayX

DayX has no editorial team and no publisher. Behind this site is one person — and a simple idea.

How it all started

The honest answer: with a zombie novel. Not too long ago, I read “Day by Day Armageddon” by J. L. Bourne. Yes — zombies. But if you ignore them, the book asks a serious question: What happens when familiar structures suddenly collapse? No electricity, no mobile network, no fully stocked supermarket.

This question wouldn’t let me go. And I found the best answers not in novels — but in official brochures from eight European countries. Well done, well documented. But: scattered, hard to read, and buried as PDFs. Does anyone really bother to read stuff like that in their free time?

That is exactly what DayX is for: These answers in one place. As tools that anyone can use — not as a stack of paper.

What DayX stands for

  • Only official sources. Every number and every tip comes from official brochures — you can see exactly which ones in the Methodology.
  • Free and without data collection. Your entries stay on your device. No account, no advertising, no tracking.
  • Calm instead of sensational. Preparedness is not the end of the world. It is common sense — like a smoke detector or the first aid kit in your car.

Who is behind it

Hello world, it's Markus

I am Markus and have been working with the web for over 20 years. DayX is not politics, nor am I a “prepper” — I just thought this tool should exist, so I built it.

I prefer to stay behind the site rather than in front of the camera. If you have any questions or find an error, I would be happy to receive a message — you can find out how to contact me in the Imprint.

When I am not working on DayX, I develop tools for WordPress — for example the Svana Suite.
