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.


A lot of cycle trackers right now sell that data and there is some concern it could be used to find women who have miscarried and charge them with a crime.
Something like your idea is safer for women to use.
How can that even be a thing? Miscarriages happen all the time
