About Artemis

Artemis is a small, independent project with one conviction: your cycle data is yours, and understanding your body shouldn’t mean handing it to a company.

Our story

Artemis started with a simple observation: the Apple Watch already measures wrist temperature every night, yet most people never see what that data can tell them about their cycle. The apps that did use it wanted an account, an email address, and a copy of the most intimate data you have.

We wanted the opposite. So we built a cycle tracker that does all of its analysis on your device, keeps its data in Apple Health, and has no servers to leak, sell, or subpoena. Partner sharing moves through Apple’s own iCloud sharing — never through us — because we believe you should be able to keep someone you trust in the loop without trusting a stranger with the details.

Who’s behind it

Artemis is built by a tiny team that cares about design, privacy, and getting the science right. We answer our own email and read every note.

Artemis is not a medical device. It provides predictions rather than diagnoses and should not be used as a form of birth control.
