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.



This is super cool! I’m not afab so I can’t help test and my question may be ignorant but I’m curious why one would want this functionality to not be something native and benefits from being hosted at all?
There are some f-droid trackers that look nice (I keep seeing one there with a super pretty ui) but I’m not sure what the tradeoffs of just using a native application for something like this might be
The benefit over a purely local app is mainly cross-device access and easier syncing/backups, while still avoiding a third-party service storing your data.
Ownership of your data, privacy concerns, apps being tracked, cross-device, no f-droid for iOS.
