Lunatwin

Terms of Use

Last updated: 9 October 2026

The service

Lunatwin is an app that estimates where someone is in their menstrual cycle from the dates you enter. It can be used by someone following their own cycle, or by a partner who wants to support them, and two accounts can be connected so they share the same cycle. It is provided by Inora AS, organisation number 837 597 102, Spelhaugen 12, 5147 Fyllingsdalen, Norway. Contact: hello@lunatwin.app.

Not medical advice, not contraception

Lunatwin gives general information based on averages. It is not medical advice, it cannot diagnose anything, and it must not be used as contraception or to plan or avoid pregnancy. Every body is different. If she has strong symptoms, she should talk to a doctor.

Use it with respect

Lunatwin is made for care, not control. If you follow your partner’s cycle, tell her you use it. Only share invitations and partner links with your partner. Don't use Lunatwin to monitor, control or pressure anyone.

Lunatwin+ subscriptions

Right of withdrawal and refunds

Lunatwin+ starts immediately when you subscribe. If you are a consumer in the EU/EEA, you have a 14-day right of withdrawal from the purchase; by starting to use Lunatwin+ during that period you accept that we may deduct a proportional amount for the time you have had access. Contact us within 14 days and we will sort it out. Beyond this, refunds are given where the law requires it.

Your account

Keep access to your email safe, since it is how you sign in. You can delete your account at any time in the app.

Liability

We work to keep Lunatwin available and correct, but it is provided as it is. To the extent the law allows, we are not liable for indirect losses or for decisions made based on the app's estimates.

Changes and governing law

We may update these terms and will tell you in the app before important changes take effect. These terms are governed by Norwegian law, without limiting any mandatory consumer rights you have where you live.
