Ovumcy is a privacy-first, self-hosted menstrual cycle tracker. It is built for people who want fast daily tracking, useful cycle insights, and data that stays under their control.
Ovumcy runs as a single Go service with a server-rendered web UI, can be installed on a phone home screen, and supports SQLite by default with Postgres as an advanced self-hosted path.
This README describes the current main branch. The latest tagged release is v0.4.0.
Why Ovumcy Exists
Most cycle tracking apps depend on cloud accounts, analytics, or third-party infrastructure.
Ovumcy is designed as a self-hosted alternative for people who want simple daily tracking, useful cycle insights, and full control over sensitive health data.
Ovumcy trades single-device simplicity for self-hosted control, operator-managed storage, and browser access from any device.
