My wife needed a cycle tracker. Everything out there was either Flo (which got sued twice for sharing health data) or an abandoned GitHub project. So I built Ovumcy. Single Go binary, SQLite, Docker-ready. No analytics, no third-party APIs, no cloud. Your data stays on your server. Features: period tracking, symptom logging, predictions (ovulation, fertile window), statistics, CSV/JSON export, dark mode, Russian and English. Just pushed v0.2.5. Looking for feedback from real users.


Thanks for doing this, I was debating doing the same. It needs to exist.
F-Droid has Drip, Bluemoon and Periodical.
Yes, I’m aware of those apps. They’re great local-first mobile trackers. Ovumcy explores a slightly different approach - a self-hosted web app that can run on infrastructure you control and be accessed from multiple devices.
