About
We built Luna because we needed it.
Most cycle apps are built by companies optimizing for engagement. Luna was built by a couple who wanted to understand each other better.
Andrea started tracking her cycle a few years ago. Like most people, she tried the apps everyone recommended. They were fine for logging, less useful for understanding. And the privacy practices of some of them made her uncomfortable.
At the same time, Jérôme, her partner, wanted to be more supportive but had no real way to understand what she was going through across the month. Existing partner features were either non-existent or felt like surveillance.
So we built Luna. Not as a startup project, but as something we genuinely needed and could not find.
What we believe
Cycle data is intimate.
It should be treated that way, not as a growth metric or an advertising signal. EU-hosted, never sold, deletable in one tap.
Uncertainty is honest.
Most apps give you one exact date. Real cycles do not work that way. Luna shows ranges, acknowledges variability, and never pretends to know more than it does.
Partners should be included, not just informed.
There is a difference between a partner seeing raw data and a partner receiving useful, plain-language context. Luna is built for the second.
