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.
Why not use drip or mensinator? Both FOSS.
Ovumcy isn’t trying to replace them. The idea here is to explore a self-hosted, web-based approach that focuses on running the app on infrastructure you control, with simple deployment and cross-device access through the browser.
Different tools optimize for different things. Native apps like Drip or Mensinator are great for fully local tracking, while Ovumcy explores a self-hosted model that can be accessed from multiple devices without relying on a third-party service.
this is great, especially when our government starts tracking everything we do online.
great forward thinking if that was your intention.
I see that we face it all over the world now.
Yup. You really don’t want the maga cult monitoring your cycle. If you stopped menstruating for a bit you must be pregnant. Where is the baby? Omg you murdered the baby by taking Tylenol!
I see how they differ now. Local vs self hosted. Niche use. But I get your idea especially helpful between partners I suppose. Keep it going! Let’s see where it lands in time. Personally I think the name is hard to remember and pronounce correctly which means it might not be super catchy and really take off. My opinion and in no way should deter you. Perhaps tweak the name. Overall though good job and keep going. This not a negative thing I say. Just to trying to help you refine the idea to success. Best of luck!
Appreciate that!
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.
I use Android, my wife - iOS. So many things that on F-Droid are simply unavailable to her (yes, I tried to convince her to go to our side). So I searched for living projects with self-hosting idea, did not find one and decided to create one. I have a CS background, though my professional work today is mostly in finance as a senior analyst where I write code to automate and optimize workflows. Ovumcy started as a personal project exploring a self-hosted approach to cycle tracking.
I use a period tracker to identify file extensions.
As a non-native speaker, I had to use LLM to get that joke)
I did the same thing for my partner. She didn’t migrate in the end, and google killed my play store account.
https://bloodyhealth.gitlab.io/ - is also a good option.
Some kind of data import would be nice to have according to my partner, but it might be tricky with all the different apps.
I like the naming:) and is there any chance to restore access to your account? It looks like it might have a future.
That link isn’t mine, and it is available and active.
Mine is https://github.com/cameroncros/PrivatePeriodTracker
But it’s abandoned. Your welcome to steal anything you like from it.
Well, not stealing, being inspired)
My partner might volunteer to try it out, but since she is very regular it probably wouldn’t help much for input.
The main feature she says she misses from Flo (we are also data savy, so she left it), was for when things were irregular, the ability for it to predict the why’s and when’s like stress, etc.
In the current iteration, if something is irregular can you put in what happened and have it auto-adjust?
Also, reminder notifications a couple of days out were helpful.
I had been considering a project like this as well, but one that uses on-device analytics to record the why’s and when’s, then allowing for scrubbed anonymous submissions (date adjusting/etc like you do in a clinical trial) to allow for algorithm development while preserving privacy.
Happy to have a conversation about this for future potential PRs (I am an avid FOSS contributor in both planning and code, even working on a project for the Linux Foundation kernel dev team now).
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.
Awesome! My wife just had her IUD removed and will probably start tracking again. Will get this set up for her and see if she likes it, will provide feedback if she has any.
Thank you, I opened Discussions for that, fell free to communicate.
