Terms of use

General terms and conditions for the Lunabia app and website. Last updated 9 September 2026. This is a translation for convenience; the German version is the binding one (see clause 15).

Lunabia is not a medical application and not a contraceptive. The app shows you your own entries and calculates estimates from them. It makes no diagnosis, gives no treatment recommendation and does not replace a conversation with a doctor, a midwife or a paediatrician. If something worries you, ask a trained person. See clause 4.

1. Who we are and what these terms cover

Lunabia is provided by Fluxera LLC, 75 E 3rd St, Ste 7, Sheridan, Wyoming 82801, United States of America, reachable at info@lunabia.com (hereafter "we"). Full details are in the legal notice.

These terms apply to the use of the Lunabia app and the website lunabia.com, including the waitlist. They apply between you and us in the version valid at the time the contract is concluded. Your own deviating terms do not become part of the contract, even if we do not expressly object to them.

How we handle your data is set out separately in the privacy statement. It is not part of these terms but an information notice under Art. 13 GDPR.

2. What Lunabia is

Lunabia is an app for the cycle, pregnancy and the first years with a child. You can record what you want to keep: bleeding, symptoms, measurements, feeds, sleep, nappies, weight, length, photos and videos. The app shows these entries back to you, summarises them and calculates estimates from them, for example the expected start of the next period or the interval between two sleep phases.

Lunabia is first of all an application on your device. Without an account, everything stays there. If you create an account, we synchronise your data between your devices and back up your photos and videos in our storage.

The app is under development. Individual features may be added, changed or removed. Clause 8 governs what applies in that case.

3. Contract, account and minimum age

The contract on use is concluded when you install and start the app. For use without an account you need to do nothing further.

For an account you provide an email address and confirm it with a code we send to that address. There is no password. You are responsible for ensuring that nobody else has access to your mailbox and your unlocked device. For the device, the app additionally offers a passcode lock.

You must be at least 16 years old to use Lunabia. If you are younger, you need the consent of the persons responsible for you.

For the waitlist on the website: you enter your address, we write to you once when the app launches. No contract on the app arises from this.

4. No medical advice, no contraception

Lunabia is expressly not a medical device within the meaning of Regulation (EU) 2017/745 and is not placed on the market as one. The app is not intended to detect, prevent, monitor, treat or alleviate any disease.

In particular:

Lunabia is not a contraceptive. Information on fertile days and ovulation consists of estimates from your own entries. They are imprecise, they can be wrong, and they are not suitable for preventing or achieving a pregnancy. If you want contraception, talk to a doctor.
The texts are general information. The weekly texts on pregnancy, the monthly texts on the child, the milestones and the notes on leaps describe what commonly happens. No child and no pregnancy follows a table. Deviations are the norm.
Growth curves are not a diagnosis. The percentiles come from the official tables of the World Health Organization. They replace neither a check-up nor an assessment by a paediatrician.
Reminders are alarms, not instructions. What the app shows about intervals between feeds or sleep phases is what you told it yourself or what it calculated from your entries.

In an emergency, call the emergency number (112 in Europe). Do not rely on an app in an acute situation.

5. Your content belongs to you

Everything you enter in Lunabia remains yours: your photos, your videos, your notes, your measurements. We acquire no ownership of it and no rights beyond this clause 5.

So that the app works, you grant us a simple right, limited in place and time to what is necessary, to store, transmit, reproduce and display your content back to you. This right serves solely to provide the service to you and ends when you delete the content or close your account.

We do not use your content for advertising, not for analysis beyond your own use, not for training artificial intelligence models, and we do not pass it on to third parties, except to the technical service providers needed for operation who are named in the privacy statement.

You warrant that you hold the rights to what you upload. If you photograph children or other people, you need their consent or, for children, that of all persons with parental responsibility. This applies especially if you share content with others via the app.

6. What you may not do

You use Lunabia for your own purposes. In particular, the following is not permitted:

uploading unlawful content, above all content that infringes the rights of third parties;
attacking or overloading the app or our servers, or circumventing security measures;
passing on or selling access data or accounts;
reverse engineering, decompiling, modifying the app or reproducing parts of it, unless permitted by law (sections 69d and 69e of the German Copyright Act);
using content of the app outside the app, see clause 7.

In case of serious or repeated violations we may block access. We will tell you why, and you can respond.

7. Our rights in Lunabia

You receive a simple, non-exclusive, non-transferable and revocable right to use Lunabia on your devices for your own purposes. No further rights are granted. In particular, you may not reproduce, distribute, make publicly available or edit content of the app unless the law expressly permits it.

The fonts Outfit and Nunito Sans are licensed under the SIL Open Font License 1.1 and are excluded from this. Other third-party components used are named in the legal notice.

8. Availability, changes and updates

We strive for continuous operation but do not owe it: Lunabia is currently free of charge, and we do not promise any particular availability. Maintenance, disruptions at our service providers and circumstances beyond our control can interrupt the service.

We may develop the app further, change features and discontinue individual features. If we change something that impairs usability for you more than insignificantly, we will tell you beforehand and with reasonable notice; you can then end the contract free of charge.

Insofar as Lunabia is a digital product within the meaning of sections 327 et seq. of the German Civil Code (BGB), we will provide you during the term of the contract with the updates necessary to maintain conformity (section 327f BGB). If you do not install a provided update within a reasonable time, we are not liable for defects resulting solely from that, provided we informed you about it.

9. Prices

Lunabia is currently free of charge. We reserve the right to offer paid additional features in the future. Nothing becomes chargeable without your express consent. Before any paid contract you will receive the legally required information including the cancellation notice.

10. Back up your data

Lunabia stores your data on your device first. If the device is lost or you delete the app, data without an account is irretrievably gone. With an account we additionally back up your content with us, but this does not replace your own backup.

There is no recovery code for the passcode lock, and we cannot reset it: it never leaves your device. If you forget it, the only option is to reinstall the app, and then the data on this device is gone.

11. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body and health, under the Product Liability Act and to the extent of a guarantee we have given.

In case of simple negligence we are liable only if we breach an obligation whose fulfilment is essential for the proper performance of the contract and on whose observance you may regularly rely (cardinal obligation). In that case our liability is limited to the foreseeable damage typical for the contract at the time of conclusion.

Otherwise our liability is excluded. The limitations also apply to our legal representatives and agents.

For decisions you take on the basis of the estimates and texts shown in the app we are not liable, in accordance with clause 4: the app gives no medical recommendation.

12. Term, termination and deletion

The contract runs for an indefinite period. You can end it at any time without notice by deleting your account or uninstalling the app. We can terminate the contract with 30 days' notice to the end of a month; the right to extraordinary termination for good cause remains unaffected.

If you delete your account, we delete the content stored for it. What we retain and for how long is set out in the privacy statement.

13. Changes to these terms

We may change these terms if there is a valid reason, such as a change in the law, new features or a change in case law. We will inform you in text form at least six weeks before the planned effective date about the change and your right to object.

If you do not object before the effective date, the change is deemed accepted. We will point this out separately in the notice. If you object, the contract ends on the effective date without any disadvantage to you.

14. Governing law, jurisdiction, dispute resolution

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law applies only insofar as it does not deprive you of the protection granted by the mandatory provisions of the law of your habitual residence (Art. 6(2) Rome I Regulation).

For consumers the statutory places of jurisdiction apply. If you are a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is our registered office.

The European Commission provides a platform for online dispute resolution: ec.europa.eu/consumers/odr. We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration board (section 36 VSBG).

15. Final provisions

Should any provision of these terms be or become invalid, the validity of the remaining provisions remains unaffected. The statutory provision takes the place of the invalid one.

These terms are written in German. Translations serve understanding only; in case of doubt the German version prevails.
