Website Terms of Use

Last updated: 12 September 2026

These terms govern your use of the Lunaire Labs website (lunairelabs.uk). For the licence that governs use of the Lunaire mobile applications — the symptom-tracking apps and the accessibility tools (AspectWise, LuxKeeper, MagniClear) — see the EULA. FuelHound is licensed under its own terms at fuelhound.lunairelabs.uk/eula.

1. Acceptance of Terms

By accessing or using the Lunaire Labs website at lunairelabs.uk (the "Website"), you agree to be bound by these Terms of Use. If you do not agree to these terms, you should not use the Website. We may update these terms from time to time. For changes that materially reduce your rights, we will give reasonable advance notice on the Website itself. The "Last updated" date at the top of this page will reflect any changes; your continued use of the Website after a material change constitutes acceptance of the revised terms.

2. Website Operator

The Website is operated by Lunaire Labs Limited, a company registered in England and Wales (company no. 17137604) ("the Operator"). Lunaire Labs Limited is not VAT-registered. Registered office and other statutory details are publicly available on the Companies House register at Companies House. For contact details, see Section 15.

3. Nature of the Website

The Website is provided solely for informational purposes — to describe the Lunaire mobile applications (the symptom and cycle trackers, and the accessibility tools, which were withdrawn from Google Play in August 2026 and remain covered here for anyone still using one), provide product information, and host legal documents (Privacy Policy, EULA). The Website does not provide any service, functionality, account system, or interactive features. It is a static informational resource only. The Operator makes no commitment to maintain, update, or continue operating the Website and may modify, suspend, or discontinue it at any time without notice or liability.

4. Acceptable Use

You may browse the Website freely. You agree not to:

5. Intellectual Property

All content on the Website — including but not limited to text, graphics, logos, icons, images, screenshots, page layouts, and underlying code — is the property of the Operator or its licensors and is protected by United Kingdom and international copyright, trademark, and other intellectual property laws.

The Lunaire and Lunaire Labs Limited names, logos, and branding are trademarks of the Operator. Nothing on the Website grants any licence or right to use any trademark without the Operator's prior written consent.

6. Health Information Disclaimer (Lunaire Symptom and Cycle Trackers)

The Lunaire Symptom and Cycle Trackers are logging tools and do not constitute medical advice, diagnosis, or treatment. Where an app shows a prediction — such as Cycle Tracker estimating a likely next period date — that is arithmetic on dates you logged yourself, presented as an estimate, and is not a clinical judgement. Where an app shows a pattern between two things you have logged — such as a food tag and a symptom appearing on the same days — that is a count and comparison of your own entries over the period shown. It does not establish that one caused the other, and it is not a clinical judgement. Under no circumstances should the data in, or any estimate or pattern shown by, a Lunaire app be used to self-diagnose or self-treat any medical condition. Always consult a qualified healthcare provider for personal medical advice. The Lunaire Accessibility Tools (AspectWise, LuxKeeper, MagniClear) are not medical devices and make no clinical claims; they apply user-configured per-app screen attributes (rotation, brightness, magnification) only.

7. App Data, Backups, and Data Loss (all Lunaire Apps)

All data you enter into any Lunaire App is stored only on your own device. Lunaire Labs holds no copy of it and cannot recover it for you under any circumstances. There is no account, cloud service, or server-side copy. The apps covered by the EULA (the symptom and cycle trackers and the accessibility tools) also deliberately opt out of their platform's automatic cloud backup and device-to-device transfer. On Android that means their data is not included in Google Account or Google One backups; on iOS the app's database is explicitly marked as excluded, so it is not included in iCloud Backup or in an encrypted local backup made through a computer. On either platform your data will not transfer automatically when you set up a new phone — you must use the in-app backup feature.

By installing and using any Lunaire App, you accept that keeping working backups — of your device and system generally, and of your Lunaire app data specifically (using the in-app backup feature, where provided) — is entirely and solely your responsibility. If your device is lost, damaged, reset, or corrupted, or an app is uninstalled or its storage cleared, any data you have not separately backed up will be permanently lost. That responsibility includes keeping a backup of the device's operating system and other contents: in the unlikely event that any app — from any developer — were ever to malfunction in a way that corrupted your device's system or other data, your own system backup is your protection, and restoring your device from it is your responsibility (your statutory rights are not affected). Full details are set out in the EULA (Section 12) and the Privacy Policy.

8. Accuracy of Information

While we endeavour to keep the information on the Website accurate and up to date, we make no representations or warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability, or availability of the Website or the information, products, services, or related graphics contained on the Website. Any reliance you place on such information is strictly at your own risk.

9. External Links

The Website may contain links to third-party websites (including but not limited to the Google Play Store, the Apple App Store, and the Information Commissioner's Office). These links are provided for convenience only. We have no control over the content, privacy policies, or practices of any third-party website and accept no responsibility or liability for them. Inclusion of any link does not imply endorsement.

10. Disclaimer of Warranties

The Website is provided on an "as is" and "as available" basis without warranties of any kind, whether express, implied, or statutory. To the maximum extent permitted by applicable law, the Operator disclaims all warranties, including but not limited to implied warranties of merchantability, fitness for a particular purpose, non-infringement, and accuracy.

The Operator does not warrant that: (a) the Website will be available at all times or without interruption; (b) the Website will be free from errors, viruses, or other harmful components; (c) any defects will be corrected; or (d) the information on the Website will always be complete, accurate, or current.

11. Limitation of Liability

To the maximum extent permitted by applicable law, the Operator shall not be liable for any direct, indirect, incidental, special, or consequential damages, including but not limited to loss of profits, data, goodwill, or business opportunity, arising out of or in connection with your use of or inability to use the Website, however caused and regardless of the theory of liability.

Nothing in these terms shall exclude or limit liability for: (a) death or personal injury caused by negligence; (b) fraud or fraudulent misrepresentation; or (c) any other liability that cannot lawfully be excluded or restricted under applicable law, including (without limitation) your rights under the Consumer Rights Act 2015.

12. Governing Law and Jurisdiction

These Terms of Use shall be governed by and construed in accordance with the laws of England and Wales. Any dispute arising out of or in connection with these terms shall be subject to the exclusive jurisdiction of the courts of England and Wales, subject to any mandatory jurisdiction provisions that may apply to you as a consumer under applicable law.

13. Privacy

Your use of the Website is also governed by our Privacy Policy, which describes how the Website handles (or, more accurately, does not handle) personal data relating to visitors. The Website does not retain access logs, set cookies, run analytics, or process any personal data in connection with your visit. Please review the Privacy Policy for full details.

14. Complaints and ADR

If something has gone wrong, please email us first at 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.

Alternative dispute resolution. We are not a member of, and do not subscribe to, any alternative dispute resolution (ADR) scheme. If we cannot settle a complaint between us, we will tell you so in writing and, as the Alternative Dispute Resolution for Consumer Disputes (Competent Authorities and Information) Regulations 2015 require, point you to a certified ADR provider competent to deal with it — while making clear whether we are willing to use that provider. You are free to take the matter to court under Section 12 whatever we say, and where you bought through Google Play or the App Store, their own dispute and refund processes are open to you as well.
