Hey HN, after the app I actually used to track my period wanted me to log in and save my data in the cloud, I decided to write my own.

Simpluna▲68I've been running Simpluna, a period-tracking app, for six years. It's a company based in Tokyo, Japan, but development and operations are basically a one-person effort.
