Monitoring when you ovulate

The latest Apple spy-watch uses sensors to monitor when you ovulate; it doesn't need to ask you. And it will give that data to various companies and governments.

With that data, governments can tell that you probably had a miscarriage or an abortion. That will provides grounds to subpoena more data so as to decide whether to prosecute you.

The device may offer you the choice to disable the feature, but since the software is non-free, which implies it is controlled by Apple rather than by the users, it could be drawing those conclusions and showing them to companies and governments, while pretending that it does not.
