  • Found out I’m pregnant and it’s already too late.
    There are some, I've seen Periodical on F-Droid before, but I saw now there's another one called drip. Probably more out there, but both of those are also available on Google Play for people who aren't FOSS nerds like me. Source: about 2 years ago
  • I'm looking for a self-hosted period tracker / pregnancy planner for my wife.
    Do you really need it hosted? Is a private app enough? For example, on Android, there's Periodical and I think it doesn't even have the internet access permission. Source: about 2 years ago
  • Everything is fine.
    If you have an Android device, Periodical is a simple tracking app that does not have Internet permission so it literally cannot share your data. You can back up its data to a text file to restore if need be, and keep that backup off your device. However, if your phone backs itself up to "the cloud" you could still incriminate yourself.
