About Cycle Calendar

Cycle Calendar brings cycle awareness into everyday life without turning it into another quantified dashboard.


Why this matters

The menstrual cycle is one of the most fundamental biological rhythms, yet it stays largely invisible in everyday relationships. That isn't personal failure - it's a systemic blind spot. Cycle Calendar tries to close it, not with more theory, but with quiet, daily context where you already look: your calendar.

About me

Hi, I'm Lutz. I work at the intersection of technology, health, and human behavior - advising ventures, supporting startups, and facilitating change in larger organizations. Cycle Calendar is a side project born from curiosity, not a company. If it helps a few people pay better attention, that's enough.
