I haven’t tried it on windows though, so I’m not sure if it will work properly on there. It’s just a personal project for now. The UI is pretty basic too.

Made my own desktop app in python (tkinter) which encrypts the data with GPG. It has predictions and potential ovulation days. The predictions seem pretty accurate so far.

Thanks
