Why this tool is free

A personal need

I live with chronic migraine. I first made this tool for myself, to replace my neurologist's paper calendar, and I share it because it may help other people in the same situation. That is the only reason this project exists.

What I will not do

As long as I run this project: no subscription, no advertising, no resale of your data, no trackers. Your data is used for you alone. You can export it or delete your account at any time.

What it costs

I do not hide the figures. This is what I pay for the tool to exist.

Server (Hetzner, in Europe)

€4.49 a month, excluding VAT

Domain name

€10 a year

Total

about €64 a year

2026 figures, paid since December 2025; the domain renews at the same price. For now the server also runs other personal projects, so this tool's share is smaller than that amount. I do not count my time, nor my development tools.

If the costs weigh on me one day

If these costs ended up weighing on me too much, I would look for solutions other than a subscription or advertising, and I would write it here before any change. You will not be put in front of a done deal.

Who is behind it

Cédric Dekimpe, in Belgium. I am a developer by trade and my first aim is to help people who, like me, suffer from chronic migraine.
