Lunaire Apps — End-User Licence Agreement

Last updated: 29 April 2026

This EULA covers all Lunaire mobile applications — the symptom-tracking apps (Cycle, Menopause, PMDD, Endo, Thyroid, IBS, Fibro, POTS and Lupus) and the accessibility tools (AspectWise, LuxKeeper). It is a legal agreement between you and Lunaire Labs Limited. By downloading, installing, or using any Lunaire App, you confirm that you have read, understood, and agree to be bound by every term below. Nothing in this Agreement affects your statutory rights under the Consumer Rights Act 2015 or any other applicable UK consumer-protection legislation.
Health disclaimer (Lunaire Health Apps): The Lunaire Health Apps are personal wellness trackers. They are not medical devices, are not intended to diagnose, treat, cure or prevent any disease or medical condition, and must not be relied upon as a substitute for professional medical advice, diagnosis or treatment. Under no circumstances should the data in any Lunaire Health App be used to self-diagnose or self-treat any medical condition. Always seek the advice of a qualified healthcare provider with any questions about a medical condition, and never disregard professional medical advice or delay seeking it because of information provided by the App. In a medical emergency, contact emergency services immediately.
Accessibility-tool disclaimer (AspectWise, LuxKeeper): The Lunaire Accessibility Tools are designed to help users with vestibular disorders, motor impairments, low vision, photophobia, migraine sensitivity or other personal accessibility needs by applying user-configured per-app rotation or brightness preferences. They are not medical devices, are not assistive technologies certified to any medical or accessibility standard, do not provide medical advice, and make no clinical claims. Suitability for your individual needs is your responsibility to assess.

1. Definitions

In this Agreement:

2. Licence Grant

Subject to the terms of this Agreement, the Developer grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to download, install, and use the App on Devices that you own or control, solely for your personal, non-commercial purposes.

The App is licensed, not sold. The Developer retains all right, title, and interest in and to the App, including all intellectual property rights therein. No title to or ownership of the App is transferred to you.

3. Licence Restrictions

Except to the extent expressly permitted by applicable law that cannot be excluded by contract, you shall not, and shall not permit any third party to:

  1. copy, reproduce, distribute, publish, display, perform, or create derivative works of the App;
  2. reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, algorithms, data structures, or underlying ideas of the App, except to the extent that such activity is expressly permitted by sections 50B, 50BA and 50C of the Copyright, Designs and Patents Act 1988 (decompilation for interoperability, observation of functioning, and necessary back-up / error correction);
  3. modify, adapt, translate, or create derivative works based on the App;
  4. rent, lease, lend, sell, sublicense, assign, distribute, or otherwise transfer rights in or to the App;
  5. remove, alter, obscure, or tamper with any copyright notice, trademark, or other proprietary rights notice;
  6. use the App for any unlawful purpose or in violation of any applicable law or regulation;
  7. bypass, disable, circumvent, or interfere with any security, licensing, or access-control mechanism;
  8. use the App to develop a competing product or service;
  9. use the App for any commercial purpose, including providing health-tracking services to third parties;
  10. use any automated system, including scripts, bots, or scrapers, to interact with or extract data from the App.

4. Intellectual Property Rights

The App is protected by copyright laws, international copyright treaties, and other intellectual property laws. All title, ownership, and intellectual property rights in and to the App — including all source code, object code, algorithms, user interface designs, graphics, icons, text, images, the name "Lunaire", the name "Lunaire Labs", and the selection, coordination, and arrangement thereof — are and shall remain the exclusive property of the Developer. All rights not expressly granted are reserved.

5. Health and Medical Disclaimer

Applies to all Lunaire Apps. No Lunaire App is a medical device. None has been evaluated, cleared, or approved by any regulatory authority, including the Medicines and Healthcare products Regulatory Agency (MHRA) or any equivalent body. No Lunaire App provides medical advice, diagnosis, or treatment.

Lunaire Health Apps. The Lunaire Health Apps provide general wellness-tracking features for personal informational purposes only. Any predictions, estimates, or calculations provided by these Apps (including but not limited to cycle predictions, fertile-window estimates, symptom trends, or symptom correlations) are approximations based on data you enter and general statistical models. They are not guaranteed to be accurate and must not be relied upon for medical decisions, family planning, contraception, or any health-critical purpose.

Lunaire Accessibility Tools. The Lunaire Accessibility Tools (AspectWise, LuxKeeper) are intended to help users with vestibular disorders, motor impairments, low vision, photophobia, migraine sensitivity or other personal accessibility needs by applying user-configured per-app screen attributes (rotation, brightness) according to rules you configure. They are not medical devices and are not assistive technologies certified to any medical or accessibility standard. Suitability for your particular needs is your responsibility to assess.

The Developer makes no representation or warranty that the information or output provided by any Lunaire App is accurate, complete, reliable, current, or error-free. You acknowledge and agree that any reliance on a Lunaire App's output is solely at your own risk.

If you have or suspect you have a medical condition, or if you are pregnant or planning to become pregnant, consult a qualified healthcare professional. Do not delay seeking medical advice because of information provided by any Lunaire App.

6. Premium Features and In-App Purchases

The App may offer optional Premium Features via in-app purchase through Google Play Billing. All transactions are processed and managed entirely by Google Play under Google's own terms of sale, and the Developer does not process, collect, or store any payment information. Lunaire Labs Limited remains the trader in respect of the digital content supplied, and your statutory rights under the Consumer Rights Act 2015 (in particular the remedies in ss.42–44 for digital content that is not of satisfactory quality, fit for purpose, or as described) are not affected by the involvement of Google Play in the payment flow. The Developer may also grant Premium Features without charge at its sole discretion (for example, by way of promotional codes, beta-tester compensation, or complimentary access); any such grant is gratuitous, is not a sale or supply for consideration, and may be modified or revoked by the Developer at any time without notice or liability.

Subscription terms, pricing, billing, auto-renewal, and cancellation for any subscription-based Premium Features are governed by Google Play's terms of service. The Developer reserves the right to modify, discontinue, or change the pricing of Premium Features at any time, subject to applicable Store policies. Changes will not affect active subscriptions until their next renewal date.

14-day right to cancel. Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 and Article 16(m) of the Consumer Rights Directive, you ordinarily have a 14-day right to cancel a purchase of digital content. However, because Premium Features are delivered as immediately-usable digital content, by completing the in-app purchase (i) you expressly consent to immediate supply of the digital content, and (ii) you acknowledge that you will consequently lose your 14-day right of cancellation once supply begins. Refunds are administered by Google Play under its own refund policy; you may also contact us for assistance. Nothing in this paragraph limits any statutory consumer right that cannot lawfully be excluded or restricted.

7. Your Statutory Rights

Nothing in this Agreement is intended to or shall affect your statutory rights as a consumer under the Consumer Rights Act 2015, the Unfair Contract Terms Act 1977, or any other applicable UK consumer-protection legislation. Under the Consumer Rights Act 2015 (Chapter 3, ss.33–47), digital content must be of satisfactory quality, fit for a particular purpose, and as described. If it is not, you may be entitled to the statutory remedies of repair, replacement, price reduction or refund under ss.42–44 of the Act. For further information about your statutory rights, contact your local Citizens Advice Bureau or Trading Standards office.

8. Disclaimer of Warranties

Subject to Section 7 (Your Statutory Rights), and to the maximum extent permitted by applicable law:

The App is provided on an "as is" and "as available" basis, without warranties of any kind, whether express, implied, statutory, or otherwise. The Developer expressly disclaims all implied warranties (other than those imposed by the Consumer Rights Act 2015), including warranties of non-infringement, accuracy, and quiet enjoyment.

The Developer does not warrant that: (a) the App will meet your specific requirements or expectations; (b) the operation of the App will be uninterrupted, timely, secure, or error-free; (c) any predictions, calculations, or estimates provided by the App will be accurate or reliable; (d) any defects or errors will be corrected; or (e) the App will be compatible with any particular Device, operating system version, or third-party software.

9. Limitation of Liability

Nothing in this Agreement shall exclude or limit the Developer's liability for: (a) death or personal injury caused by the Developer's negligence; (b) fraud or fraudulent misrepresentation; or (c) any other liability that cannot lawfully be excluded or restricted under applicable law, including the Consumer Rights Act 2015.

Subject to the foregoing, and to the maximum extent permitted by applicable law:

  1. The Developer shall not be liable for any indirect, incidental, special, or consequential damages, including but not limited to loss of profits, loss of revenue, loss of data, loss of Health Data, loss of goodwill, business interruption, emotional distress, or any other damages arising out of or in connection with this Agreement, the use of or inability to use the App, or any reliance on the App's output, however caused and regardless of the theory of liability.
  2. The Developer's total aggregate liability for all claims arising out of or relating to this Agreement or the App shall not exceed the amount you paid for the App or Premium Features.
  3. Without limiting the foregoing, the Developer shall have no liability for any loss, damage, injury, or harm arising from: your reliance on the App's predictions, estimates, or calculations for medical, contraceptive, or health-critical purposes; your failure to seek appropriate medical advice; the loss or corruption of Health Data stored locally on your Device; or any action or inaction you take based on information displayed by the App.

10. Indemnification

To the maximum extent permitted by applicable law, you agree to defend, indemnify, and hold harmless the Developer from and against any and all third-party claims, actions, demands, damages, losses, costs, liabilities, and expenses (including reasonable legal fees) arising out of or in connection with: (a) your use of the App in breach of this Agreement; (b) your violation of any applicable law, regulation, or third-party right; (c) any reliance by a third party on information provided by the App that you have shared with that third party; or (d) any negligent or wrongful act or omission by you.

11. Data and Privacy

All Health Data you enter into a Lunaire Health App, and all Rule Data you configure in a Lunaire Accessibility Tool, is stored exclusively on your Device in local app storage. The Developer does not collect, receive, transmit, access, or store any Health Data or Rule Data. For full details of how we handle (or, more accurately, do not handle) your data, please read our Privacy Policy.

You are solely responsible for the security and backup of data stored on your Device. Subject to Section 9, the Developer shall not be liable for any loss, corruption, or destruction of data stored on your Device, howsoever caused.

12. No Responsibility for Third-Party Services

The Apps are distributed through the Google Play Store. Your use of the Store is governed by Google's own terms and privacy policy. The Developer assumes no responsibility for any third-party platform, service, or website.

The Lunaire Health Apps may contain links to third-party websites (such as health-information articles). The Developer does not endorse and is not responsible for the content, accuracy, or practices of any third-party website. Use at your own risk.

The Lunaire Accessibility Tools interact with other apps installed on your Device only by applying user-configured screen attributes (rotation, brightness) while those apps are in the foreground. The Developer is not responsible for the behaviour, content, or performance of any third-party app, including any incompatibility between a Lunaire Accessibility Tool's per-app rule and a third-party app's own rotation, display, or accessibility behaviour.

13. Dispute Resolution

In the event of any dispute, the parties agree to first attempt informal resolution by contacting the Developer at the email address in Section 17. You agree to allow not less than thirty (30) calendar days for informal resolution before commencing formal proceedings.

If unresolved, either party may commence proceedings in the courts of England and Wales, which shall have exclusive jurisdiction. If you are a consumer resident in another part of the UK, the EEA or Switzerland, you may also have the right to bring proceedings in the courts of your country of habitual residence under applicable consumer-protection law; nothing in this Section limits that right.

Nothing in this Agreement shortens any statutory limitation period that applies to you as a consumer. In particular, the limitation periods set out in the Limitation Act 1980 and your remedies under the Consumer Rights Act 2015 apply in full.

14. Termination

This Agreement is effective from first download, installation, or use and continues until terminated. Your rights terminate automatically if you materially breach any term. The Developer may also terminate this Agreement for material breach or on reasonable advance notice for any other legitimate reason. If the Developer terminates this Agreement for any reason other than your material breach within 12 months of a paid purchase, your statutory remedies under ss.42–44 of the Consumer Rights Act 2015 (including the right to a refund where appropriate) remain available.

Upon termination: (a) all licences cease immediately; (b) you must cease all use of the App; (c) you must delete all copies. Termination does not affect locally stored Health Data or Rule Data, which remains under your sole control.

Sections 1, 3, 4, 5, 8, 9, 10, 11, 12, 13, and 15 survive termination.

15. General Provisions

(a) Entire Agreement

This Agreement and the Privacy Policy constitute the entire agreement between you and the Developer in respect of the App and supersede all prior understandings.

(b) Severability

If any provision is held to be invalid or unenforceable, it shall be modified to the minimum extent necessary to make it enforceable or, failing that, severed. The remaining provisions shall continue in full force and effect.

(c) No Waiver

The Developer's failure to exercise or enforce any right or provision shall not constitute a waiver of that right or provision.

(d) Assignment

You may not assign, transfer, or sublicense any of your rights or obligations under this Agreement without the Developer's prior written consent. The Developer may assign this Agreement without your consent but will remain liable for its obligations under this Agreement; if assignment materially prejudices your rights you may terminate under Section 14.

(e) Force Majeure

The Developer shall not be liable for any failure or delay in performing any obligation under this Agreement where such failure or delay results from any cause beyond the Developer's reasonable control, including acts of God, natural disaster, war, terrorism, riot, fire, flood, strikes, infrastructure failure, power outage, or internet service disruption.

(f) No Third-Party Beneficiaries

This Agreement is for the sole benefit of the parties hereto. The Contracts (Rights of Third Parties) Act 1999 shall not apply to this Agreement.

(g) Governing Law

This Agreement and any dispute or claim arising out of or in connection with it (including non-contractual disputes or claims) shall be governed by and construed in accordance with the laws of England and Wales, subject to the consumer-jurisdiction carve-out in Section 13.

(h) Amendments

The Developer may modify this Agreement from time to time. The most current version will always be available at lunairelabs.uk/eula, and the "Last updated" date at the top of this page will reflect any changes. For changes that materially reduce your rights or the App's features, the Developer will give reasonable advance notice via an in-app notice, the Website, or the Google Play listing. Your continued use of the App after a material change constitutes acceptance of the modified Agreement. If you do not agree to a material change, you may cease using and uninstall the App; your statutory consumer rights (including any remedies under the Consumer Rights Act 2015 if the change renders the App non-conforming) are not affected.

16. Export Compliance

You agree to comply with all applicable export and re-export control laws and regulations, including without limitation the UK Export Control Act 2002 and orders made under it (including the Export Control Order 2008), the Sanctions and Anti-Money Laundering Act 2018 and regulations made under it, and any other applicable trade restrictions. You shall not, directly or indirectly, export, re-export, or transfer the App to any country, entity, or person prohibited by such laws.

17. Complaints and Contact

If something has gone wrong, please email us first at support@lunairelabs.uk and we will do our best to resolve it. You may also contact Trading Standards via Citizens Advice (citizensadvice.org.uk) for consumer advice, or the Information Commissioner's Office (ico.org.uk) for privacy matters.

By downloading, installing, or using any Lunaire App, you acknowledge that you have read this Agreement, understand its terms, and agree to be legally bound by it.
