I built a self-hosted period tracker because I couldn't find one worth using (github.com)

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, this is really useful feedback.

The reminder part is already on the roadmap, and I’ve now added two more issues based on your note about irregular cycles:

#17 Add irregularity factor tags for cycle tracking
#18 Use recorded cycle factors to improve prediction context

The direction I’d want for Ovumcy is less “the app predicts the why” and more:

users can log things like stress, illness, travel, sleep disruption, etc.
the app can use that to give better context and reliability hints for irregular cycles
without pretending to make hard medical claims

The anonymous scrubbed-submission idea is interesting too, but I’d treat that as much later, because it changes the privacy/trust model a lot.

Happy to keep talking about it, and future PRs would definitely be welcome.
