Lunaire Apps — End-User Licence Agreement

Last updated: 1 October 2026

This Agreement is between you and Lunaire Labs Limited. It covers the nine Lunaire symptom and cycle trackers listed in Section 1 — the only mobile apps we publish — and three accessibility tools we have withdrawn (Section 18). FuelHound, also withdrawn, has its own agreement (Section 18). By downloading, installing or using a Lunaire app, you agree to it. Nothing in this Agreement affects your statutory rights under the Consumer Rights Act 2015 or any other consumer-protection law.
Not medical advice. The apps are personal diaries, not medical devices. They do not diagnose, treat, cure or prevent any condition. Nothing in an app should be used to self-diagnose or self-treat, or to make decisions about contraception or family planning. Always ask a qualified healthcare provider about a medical condition, and never delay seeking advice because of something an app shows. In an emergency, contact the emergency services. See Section 5.
Important: backups. Your entries are stored only on your phone. We hold no copy, so we cannot recover them. Your phone’s automatic backup does not include them (Google’s on Android, iCloud on iOS), and you should not rely on setting up a new phone to bring them across. If you do not make your own backup files, with a strong password, and keep them somewhere safe, losing, resetting or replacing your phone means your data is permanently lost. See Section 8.

1. Definitions

2. Your licence, and who may use the Apps

We give you a limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to download, install and use the App on Devices you own or control, for your own personal, non-commercial use.

You must be at least 13, or any higher minimum age that the Store or your local law sets. If you are under 18 (or the age of majority where you live), a parent or guardian must have read and agreed to this Agreement for you. By accepting it you confirm that you have the legal capacity to do so.

The App is licensed, not sold. We keep all rights in it, and no ownership passes to you.

3. What you may not do

Except as the law allows in a way that cannot be excluded by contract, you must not (and must not let anyone else):

  1. copy, distribute, publish, modify, adapt, translate or make derivative works of the App;
  2. reverse engineer, decompile or disassemble it, except as sections 50A, 50B, 50BA and 50C of the Copyright, Designs and Patents Act 1988 allow (back-up copies, decompiling for interoperability, observing how it works, and correcting errors);
  3. rent, lend, sell, sublicense or otherwise transfer it;
  4. remove or alter any copyright, trade mark or other notice;
  5. use it unlawfully, or get around any security, licensing or access control;
  6. use it to build a competing product, or for any commercial purpose, including tracking symptoms for others as a service;
  7. use bots, scripts or scrapers to interact with it or extract data from it.

4. Ownership

The App — its code, design, graphics, icons, text and the names “Lunaire” and “Lunaire Labs” — belongs to us and is protected by copyright and other intellectual property laws. All rights not expressly given to you are reserved.

5. Not medical advice

No App is a medical device, and none has been assessed or approved by any regulator, including the Medicines and Healthcare products Regulatory Agency (MHRA). No App gives medical advice, diagnosis or treatment.

The Apps are for keeping a personal record. Any estimate, trend or pattern they show — a next-period or fertile-window estimate, a symptom trend, or two things you logged appearing on the same days — is arithmetic on your own entries: averages, counts and comparisons, shown as an estimate. It is not a clinical judgement, and no clinical model, dataset or professional assessment lies behind it. A pattern between two things you logged does not show that one caused the other. None of it is guaranteed to be accurate, and it must not be relied on for medical decisions, family planning, contraception or any other health-critical purpose.

We do not promise that anything an App shows is accurate, complete, current or error-free, and relying on it is at your own risk. If you have or suspect a medical condition, or you are pregnant or planning to be, consult a qualified healthcare professional.

6. Premium and purchases

Premium is bought through the Store, under the Store’s own terms of sale, and we never see or store your payment details. We remain responsible to you as a trader for the digital content, and your rights under ss.42–44 of the Consumer Rights Act 2015 (the remedies for digital content that is faulty, unfit for purpose or not as described) are not affected by the Store’s role.

What a purchase covers. Premium is bought per App and per Store. Premium in one Lunaire App does not unlock another, and because Google and Apple do not share purchases with each other, Premium bought on Google Play does not carry across to the App Store version, or vice versa. “Restore Purchases” works within the Store and account you bought with.

What “Lifetime” means. A one-off Lifetime purchase unlocks that App’s Premium on the Store you bought it from, with no recurring charge and no expiry date, for as long as the App remains available there. It is not a promise that the App will remain available indefinitely. If an App is ever withdrawn, the copy on your Device keeps working, and your statutory rights are unaffected.

Changes. We may change, withdraw or re-price Premium features, subject to the Store’s rules; an active subscription is unaffected until its next renewal. This is not a right to take away, without remedy, something you have paid for: where a change would deprive you of the substance of what you bought, your remedies under ss.42–44 of the Consumer Rights Act 2015 apply in the ordinary way.

Free Premium. We may give Premium without charge, for example through a promotional code. Any such grant is a gift, not a sale, and we may change or withdraw it at any time.

Subscriptions. Subscriptions renew automatically until you cancel them. On Google Play, cancel in Google Play before the end of the current billing period; on the App Store, cancel in your Apple Account’s subscription settings at least 24 hours before it ends.

Google Play. The law gives a 14-day right to cancel a distance purchase of digital content, but under the Google Play Terms of Service, with Google Commerce Limited as the seller, you agree at the moment of purchase that the content is supplied immediately and so give up that right. That happens in Google’s purchase process, not in this Agreement: this Agreement does not ask you to give up, and cannot take away, any cancellation or refund right you have. You can still ask Google for a refund under its own refund policies, through your Google Play account, and your rights under ss.42–44 of the Consumer Rights Act 2015 are unaffected.

Apple App Store. On the App Store you buy Premium through Apple, under the Apple Media Services Terms and Conditions. Depending on where you live, Apple either sells it to you itself or acts as our agent; either way, Apple handles payment, cancellation and refunds. Those terms, not this Agreement, set your cancellation and refund rights, including Apple’s 14-day cancellation terms and their exception for content whose delivery has started. Ask Apple for refunds through Report a Problem (reportaproblem.apple.com). This Agreement does not ask you to give up, and cannot take away, any cancellation or refund right you have.

7. Your statutory rights

Nothing in this Agreement affects your statutory rights as a consumer under the Consumer Rights Act 2015, the Unfair Contract Terms Act 1977 or any other consumer-protection law. Under the Consumer Rights Act 2015 (ss.33–47), digital content must be of satisfactory quality, fit for purpose and as described. If it is not, you may be entitled to a repair, replacement, price reduction or refund under ss.42–44. For advice, contact Citizens Advice or Trading Standards.

8. Your data and backups

Summary: Your Data is stored only on your phone. We hold no copy and cannot recover it. If you have not made your own backup file, with a strong password, and kept it somewhere safe, then losing, resetting or replacing your phone means Your Data is permanently lost.

(a) We hold no copy and cannot recover it

The Apps have no accounts, servers, cloud storage or syncing, and nothing you enter is ever sent to us. So if Your Data is deleted, corrupted or lost, we cannot restore, recover or rebuild any of it, in any circumstances. No support request, proof of purchase or Premium can change that. It is the unavoidable result of the private design you choose by installing the App, and you accept it as a condition of the licence in Section 2.

(b) Your phone’s own backup does not include it

On either platform, reinstalling an App gives you an empty App. A phone backup, a Google or Apple account, a manufacturer’s transfer tool or a phone shop will not move Your Data. Moving to a new Device without first making a backup file yourself, and restoring it yourself, loses everything.

(c) When Your Data will be lost

Without a separate backup file, Your Data is permanently lost if:

iOS’s Offload App is not on that list: it removes the App but keeps its data for when you reinstall. It is not a backup, though — the data it keeps is still only on that Device.

(d) Keeping backups is your responsibility

By downloading, installing or using an App, you accept sole responsibility for keeping working, up-to-date backups — of your Device and its operating system generally, and of Your Data specifically. At the least, you should:

That responsibility covers the Device’s operating system and everything else on it, not only Your Data. No App is known or expected to damage your Device, its system, other apps or other data. However, no software can be guaranteed free of faults, and your own system backup is your first protection against software faults of any kind, from any developer. Subject to Section 8(f) and to your statutory rights (including s.46 of the Consumer Rights Act 2015), restoring your Device, its system, its apps and its data is your responsibility, from your own backups.

(e) The App’s backup features

Manual backup is free for everyone. It saves all Your Data to a single file in a place you choose, optionally protected by a password. Scheduled backup is a Premium extra on Android only: it saves a copy to a folder you choose each week or month. It is off unless you switch it on, and it does not replace manual backup.

Both write only to a place you choose. They are exports under your control, not a cloud backup service, and we never receive, see or keep a backup file, or know that one was made. If you save to a cloud service, or later move, share or upload a file, that copy is governed by that service’s terms and by how you handle it (Section 12).

(f) No warranty for backups, and liability for lost data

Subject to Section 7 and to the fullest extent the law allows, the backup and restore features are provided “as is”, like the rest of the App (Section 9). We do not promise that a backup will be made, or made on time; that a backup file will be complete, readable or still where you left it; or that a file made by one version of an App, or on one Device, will restore on another.

Subject to Sections 7 and 10, and to the fullest extent the law allows, we are not liable for the loss, corruption, deletion or destruction of Your Data, backup files or any other data on or exported from your Device, however caused — including Device failure, loss or theft, the operating system, other software, your own actions, or a failure of the App’s own backup or restore. The same applies to damage to the Device, its operating system or any other app or content on it, and to the time and cost of recovering, restoring or reinstalling any of them, against which your own backups are your protection.

Nothing in this Section 8 excludes or limits any liability that the law does not allow us to exclude or limit — including under Section 10’s carve-outs, your rights under the Consumer Rights Act 2015 (digital content that is of satisfactory quality, fit for purpose and as described, with the remedies in ss.42–44), and your rights under s.46 of that Act where digital content we supply damages your Device or other digital content that belongs to you. This Section sets out who is responsible for backups; it is not an attempt to avoid liability for our own failure to meet the standards the law requires of us.

(g) Your acknowledgement

By downloading, installing or using an App, you confirm that you have read this Section 8; that backing up your Device, your system and Your Data is your responsibility; that your phone’s automatic backup and transfer features do not protect Your Data (Section 8(b)); and that we hold no copy and cannot recover it for you.

9. No other warranties

Subject to Section 7, and to the fullest extent the law allows, the App is provided “as is” and “as available”, and we exclude all warranties not imposed by the Consumer Rights Act 2015. We do not promise that the App will meet your needs, work without interruption or error, give accurate estimates, have every fault fixed, or work with any particular Device, operating system version or other software.

10. Limits on our liability

Nothing in this Agreement excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else the law does not allow us to exclude or limit, including under the Consumer Rights Act 2015. Subject to that, and to the fullest extent the law allows:

  1. we are not liable for any indirect, incidental, special or consequential loss — including loss of profits, revenue, goodwill or data, loss of Your Data, business interruption or emotional distress — arising from this Agreement, from using or being unable to use the App, or from relying on anything it shows;
  2. our total liability for all claims about this Agreement or the App is limited to the greater of the amount you paid for the App or Premium and £100;
  3. we are not liable for harm arising from relying on the App’s estimates for medical, contraceptive or other health-critical purposes, from not seeking medical advice, from the loss or corruption of Your Data on your Device, or from anything you do or do not do because of what the App shows; and
  4. you accept that these limits are a fair allocation of risk — given that the Apps are low-cost consumer software, that Your Data stays under your sole control on your Device, and that Section 7 preserves your statutory rights in full — and that we could not offer the Apps on these terms without them.

11. Information you share

If you choose to share information from an App with someone else, that is your decision, and we are not responsible for how they use it.

12. Other companies’ services and websites

Your use of a Store is governed by that Store’s own terms and privacy policy. The Apps link to other websites, such as health-information articles; we do not endorse them and are not responsible for their content or practices. We are not responsible for any third-party platform, service or website.

13. Disputes and governing law

If a dispute arises, please contact us first (Section 17) and allow at least 30 days for us to resolve it before starting formal proceedings.

This Agreement, and any dispute about it (including non-contractual disputes), is governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction. If you are a consumer living elsewhere in the UK, in the EEA or in Switzerland, you keep the protection of the mandatory consumer laws where you live and may bring proceedings in your local courts. Nothing in this Agreement shortens any limitation period that applies to you as a consumer: the Limitation Act 1980 and your remedies under the Consumer Rights Act 2015 apply in full.

14. Ending this Agreement

This Agreement starts when you first download, install or use an App and continues until it ends. You may end it at any time by deleting the App from your Device. It ends automatically if you materially breach it. We may also end it for material breach, or on reasonable notice for any other legitimate reason; if we end it for any reason other than your material breach, your remedies under ss.42–44 of the Consumer Rights Act 2015 (including a refund where appropriate) remain available, within the statutory limitation periods.

When it ends, your licence ends and you must stop using and delete the App. Your Data on your Device remains yours. Sections 1, 3, 4, 5, 8 to 13, 15, 18 and 19 continue to apply after it ends.

15. General

(a) Entire agreement

This Agreement is the whole agreement between you and us about the App. Our Privacy Policy explains how personal information is handled; it is a separate notice and does not form part of this Agreement. This does not exclude liability for fraud or fraudulent misrepresentation, and does not stop you relying on information we gave you before you installed the App — such as what the Store listing or our website said — where the law lets you; under the Consumer Rights Act 2015 such information can form part of the contract.

(b) Severability

If a court finds any part of this Agreement invalid or unenforceable, that part is changed as little as necessary to make it enforceable, or removed, and the rest continues to apply.

(c) No waiver

If we delay in enforcing a right, we do not waive it.

(d) Transfer

You may not transfer your rights or obligations under this Agreement without our written consent. We may transfer this Agreement, but we remain liable for our obligations; if a transfer materially harms your rights, you may end this Agreement under Section 14.

(e) Events outside our control

We are not liable for failures or delays caused by events outside our reasonable control, such as natural disaster, war, terrorism, riot, fire, flood, strikes, power cuts, or failures of infrastructure or internet services.

(f) Third-party rights

Only you and we have rights under this Agreement, and the Contracts (Rights of Third Parties) Act 1999 does not apply, with one exception, in Section 19(j): if you got the App from the Apple App Store, Apple Inc. and its subsidiaries are third-party beneficiaries of this Agreement and may enforce it against you. Apple requires this as a condition of distribution, and it applies to Apple alone.

(g) Changes to this Agreement

We may change this Agreement. The current version is always at lunairelabs.uk/eula, with the date of the last change at the top. For a change that materially reduces your rights or the App’s features, we will give reasonable advance notice in the App, on our website or on the Store listing. If you keep using the App after a material change, you accept it; if you do not agree, you can stop using and uninstall the App. Your statutory rights, including remedies if a change makes the App non-conforming, are unaffected.

16. Export compliance

You must comply with all export control and sanctions laws that apply to you, including the Export Control Act 2002 and orders made under it, and the Sanctions and Anti-Money Laundering Act 2018 and regulations made under it, and must not export or transfer the App to any country, organisation or person those laws prohibit.

17. Complaints and contact

If you have a complaint, please email us first at support@lunairelabs.uk and we will aim to resolve it. You can also get consumer advice from Citizens Advice (citizensadvice.org.uk), or contact the Information Commissioner’s Office (ico.org.uk) about privacy.

18. Apps we no longer sell

The nine apps in Section 1 are the only mobile apps we publish. Four earlier Android apps (FuelHound, AspectWise, LuxKeeper and MagniClear) were withdrawn from Google Play in August 2026 and are no longer available.

FuelHound (com.fuelhound) is not covered by this Agreement. Its own agreement still applies: fuelhound.lunairelabs.uk/eula.

AspectWise, LuxKeeper and MagniClear, our accessibility tools (uk.lunairelabs.aspectwise, uk.lunairelabs.luxkeeper, uk.lunairelabs.magniclear), remain Apps under this Agreement for anyone who still has one on their Device, and it applies to them as it does to the trackers, with these points:

19. Apple App Store — additional terms

This section applies only if you got the App from the Apple App Store. Apple requires these terms as a condition of distribution. Where they conflict with anything earlier in this Agreement, this section prevails for App Store users. Nothing here affects your statutory rights under the Consumer Rights Act 2015.

(a) This Agreement is with us, not Apple

This Agreement is between you and Lunaire Labs Limited only, not Apple. We, not Apple, are solely responsible for the App and its content.

(b) Scope of licence

The licence in Section 2 is a non-transferable licence to use the App on any Apple-branded product you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may be used by other accounts associated with you through Family Sharing or volume purchasing.

(c) Maintenance and support

We are solely responsible for any maintenance and support for the App, as set out in this Agreement or required by law. Apple has no obligation whatsoever to provide any maintenance or support for the App.

(d) Warranty

We are solely responsible for any product warranties, express or implied by law, to the extent not effectively excluded. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App (if any) to you. To the fullest extent the law allows, Apple has no other warranty obligation whatsoever for the App, and any other claims, losses, liabilities, damages, costs or expenses caused by a failure to conform to a warranty are our sole responsibility. This does not affect your statutory rights.

(e) Product claims

We, not Apple, are responsible for dealing with any claims by you or any third party about the App or your possession and use of it, including: (i) product liability claims; (ii) any claim that the App fails to meet a legal or regulatory requirement; and (iii) claims under consumer protection, privacy or similar laws, including in connection with Your Data.

(f) Intellectual property claims

If a third party claims that the App, or your possession and use of it, infringes their intellectual property rights, we, not Apple, are solely responsible for investigating, defending, settling and discharging that claim.

(g) Legal compliance

You confirm that you are not located in a country subject to a US Government embargo, or designated by the US Government as a “terrorist supporting” country, and that you are not on any US Government list of prohibited or restricted parties.

(h) Developer name and address

Lunaire Labs Limited, 818 Whitchurch Lane, Whitchurch, Bristol, England, BS14 0JP. Telephone: +44 20 8088 5480. Please send questions, complaints and claims about the App to support@lunairelabs.uk or that telephone number.

(i) Third-party terms

You must comply with any applicable third-party terms when using the App.

(j) Apple as third-party beneficiary

You agree that Apple and Apple’s subsidiaries are third-party beneficiaries of this Agreement, and that when you accept it, Apple will have the right (and will be treated as having accepted the right) to enforce it against you as a third-party beneficiary. This is the only exception to Section 15(f).

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