At the end of the day, Bethany’s best advice — which she acknowledged “nobody really wants to hear” — is to not put anything online (or in an app) that you’re not comfortable with being made public. As long as your data gives inference to the fact that you were pregnant and then not pregnant (and didn’t give birth, of course), law enforcement could have reasonable suspicion to investigate. However, it’s just as important that we don’t rage against or abandon femtech either.
If you do choose to delete your period tracking app, confirm that deleting the app automatically deletes your data. Sometimes, companies will only delete your data upon request, if at all.
