Yes, and we mean it. eluna works with no account at all, and anything it reads from Apple Health never leaves your phone. We don't sell your data, we don't run ads, and we never will. Your body is nobody's business but yours.

Most apps hand every woman the same advice. eluna reads the phase you're actually in and changes with you: the color, the tone, the guidance, the questions it asks. Less a calendar, more a companion that finally speaks to today's version of you.

Only what you choose. Out of the box they see your phase, your mood and your energy, and you can switch any of it off. Your cycle day, symptoms and fertile window stay hidden unless you turn them on. They never see your journal or your notes, and you can pause their access anytime. You stay in control, always.

Especially then. eluna learns your real rhythm instead of assuming a perfect 28 days, so the more you log, the better it knows you: irregular, long, short, or still finding itself. You're not broken, and eluna was built to prove it.

No, and we'd never pretend otherwise. eluna is not birth control and not a medical device. Its predictions are estimates, not guarantees. To prevent or plan a pregnancy, please talk to a healthcare professional. We'd rather be honest than risk your trust.
