Lunaire Apps — End-User Licence Agreement

Last updated: 29 April 2026

1. Definitions

In this Agreement:

• "Agreement" means this End-User Licence Agreement, as amended from time to time in accordance with Section 16(h).
• "Developer", "Lunaire Labs", "we", "us", or "our" means Lunaire Labs Limited, a company registered in England and Wales (company no. 17137604). Lunaire Labs Limited is not VAT-registered. Registered office and other statutory details are publicly available on the Companies House register at Companies House. Contact: support@lunairelabs.uk.
• "App" or "Software" means any of the Lunaire mobile applications for Android, namely:
  • Lunaire Health Apps: Lunaire: Cycle Tracker, Lunaire: Menopause Tracker, Lunaire: PMDD Tracker, Lunaire: Endo Tracker, Lunaire: Thyroid Tracker, Lunaire: IBS Tracker, Lunaire: Fibro Tracker, Lunaire: POTS Tracker, Lunaire: Lupus Tracker (store listings may show these names in localized form for your language and region; the localized listing refers to the same App).
  • Lunaire Accessibility Tools: AspectWise (per-app rotation accessibility tool), LuxKeeper (per-app brightness accessibility tool), MagniClear (per-app screen-magnification accessibility tool).
  Including all associated files, data, documentation, updates, patches, and any modified versions thereof. FuelHound is not an "App" for the purposes of this Agreement; it is licensed under its own end-user licence agreement at fuelhound.lunairelabs.uk/eula.
• "User", "you", or "your" means the individual who downloads, installs, or uses the App.
• "Device" means a compatible mobile phone or tablet running a supported version of the Android operating system.
• "Store" means the Google Play Store.
• "Premium Features" means the optional paid features of the App available via in-app purchase or subscription through Google Play Billing.
• "Health Data" means any data you enter into a Lunaire Health App relating to symptoms, pain, flares, food intake, exercise, supplements, weight, temperature, menstrual cycles, or other health and wellness information.
• "Rule Data" means any per-app preference rules you configure in a Lunaire Accessibility Tool (for example, "Google Maps → Landscape" in AspectWise, "Kindle → 30%" in LuxKeeper, or a per-app zoom level in MagniClear).

2. Licence Grant; Eligibility

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.

You must be at least 13 years old — or any higher minimum age that Google Play or applicable law sets for your territory — to use an App. If you are under 18 (or the age of majority where you live), you confirm that a parent or guardian has reviewed this Agreement and agrees to it on your behalf. By accepting this Agreement you confirm that you have the legal capacity to enter into it.

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, MagniClear) 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, magnification) 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 responsible to you as a 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 Google's role in the purchase. 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 cancellation right — not available in practice on Google Play. In practice, purchases of digital content on Google Play come with no 14-day cooling-off refund. The law (the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, and the equivalent rules in the EEA) creates 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 contracting seller, you agree at the moment of purchase that the content is made available to you immediately and that you consequently waive that statutory right of withdrawal. That waiver happens in Google's purchase process, not in this Agreement: this Agreement does not ask you to waive, and cannot take away, any cancellation or refund right you have in respect of your purchase. Refunds remain available under Google Play's own refund policies (request them through your Google Play account), and nothing in this paragraph limits the statutory remedies described above — including under ss.42–44 of the Consumer Rights Act 2015 if the digital content is faulty or not as described — or any other statutory right that cannot lawfully be excluded or restricted.

7. Your Statutory Rights

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.
4. You acknowledge and agree that the limitations of liability set out in this Section 9 reflect a reasonable and fair allocation of risk between you and the Developer — having regard to the nature of the Apps as low-cost consumer software, the fact that all data remains under your sole control on your Device, and the statutory rights preserved in full by Section 7 — and that the Developer would not make the Apps available on these terms without them.

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, as set out in full in Section 12. 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. Backups, Data Loss, and Your Responsibility for Your Device

(a) We hold no copy of your data and cannot recover it

As set out in Section 11 and in our Privacy Policy, the Lunaire Apps have no user accounts, no server, no cloud storage, and no synchronisation service. Nothing you enter is ever transmitted to the Developer. It follows that if the data on your Device is deleted, corrupted, or lost, the Developer cannot restore, recover, recreate, reconstruct, or assist in the recovery of it, in whole or in part, under any circumstances whatsoever. No support request, proof of purchase, or Premium entitlement can change this. This is an unavoidable consequence of the privacy-first design you are choosing when you install the App, and you accept it as a condition of the licence granted under Section 2.

(b) Android's own backup does not protect your Lunaire data

The Lunaire Health Apps and the Lunaire Accessibility Tools are deliberately published with Android's automatic backup and device-transfer functions disabled (android:allowBackup="false", with cloud backup and device transfer additionally excluded in the App's data-extraction rules). This is a privacy decision: it prevents your health data being copied to Google's servers without your knowledge or consent. The direct and important consequence for you is that:

• your Health Data and Rule Data are not included in Google One, Google Account, or any other Android automatic cloud backup;
• your Health Data and Rule Data are not transferred by Android's device-to-device or "copy apps & data" flow when you set up a new phone;
• reinstalling one of these Apps, on the same Device or a new one, will give you an empty App.

Moving to a new Device without first creating a backup file yourself, and restoring it yourself, will lose everything you have recorded. Do not assume that a general phone backup, a Google account, a manufacturer transfer tool, or a mobile network shop's transfer service will carry your Lunaire data across. It will not.

(c) Events that will permanently destroy your data

Your data will be permanently and irrecoverably lost if any of the following occurs and you do not hold a separate backup file:

• uninstalling the App, or using "Clear Data" / "Clear Storage" in Android Settings;
• a factory reset, device wipe, or operating-system reinstall or reflash;
• loss, theft, breakage, water damage, battery failure, storage-chip failure, or any other loss of or damage to the physical Device;
• corruption of the Device's storage or file system — whether caused by hardware fault, the operating system, a failed or interrupted system update, another app, or malware;
• the Device running out of available storage while data is being written;
• replacing, selling, returning, or handing in the Device without exporting your data first;
• your own use of the App's delete features, or an accidental deletion or overwrite by you or by anyone else with access to your Device.

(d) You are responsible for maintaining your own backups

By downloading, installing, or using any Lunaire App, you accept sole responsibility for maintaining adequate, current, and working backups — both of your Device and its operating system generally, and of your Lunaire data specifically. This responsibility rests with you at all times and is not shared with, delegated to, or assumed by the Developer in any respect.

In practice, this means you should at minimum:

• keep your own system and data backup regime for the Device as a whole, appropriate to how much the data on it matters to you;
• create a Lunaire backup file at regular intervals, in proportion to how much data you would be willing to lose;
• create a fresh Lunaire backup file before any operating-system update, factory reset, repair, warranty return, sale, or replacement of your Device;
• copy your backup files off the Device — to a computer, an external drive, or a cloud storage service of your own choosing. A backup file that exists only on the Device it came from will be destroyed together with that Device and protects you against nothing except accidental in-app deletion;
• check from time to time that your backup files still exist, are not zero-length or truncated, and can actually be restored.

For the avoidance of doubt, your responsibility for backups extends to the Device's operating system and everything else on the Device — not only your Lunaire data. No software of any complexity can be guaranteed entirely fault-free. Although a Lunaire App interfering with or corrupting the Android operating system, other apps, or other data on the Device is not an expected, known, or intended failure mode of any Lunaire App, your own system backup is your protection of first resort against software faults of any kind, from any app and any developer. Subject to Section 12(g) below and to your statutory rights (including s.46 of the Consumer Rights Act 2015), the recovery, restoration, or reinstallation of your Device, its operating system, its apps, and its data is your responsibility, to be met from your own backups.

(e) The App's backup features — what they are and what they are not

Lunaire Health Apps. The Health Apps include a manual backup feature, available to all users at no charge, which exports your data to a single file in a location on your Device that you choose, and which you may optionally protect with a password. Premium users may additionally enable a scheduled automatic backup, which writes a copy to a folder you nominate on a weekly or monthly cycle. This scheduled backup is an optional extra, is switched off unless you turn it on, and does not replace the manual backup.

Both features write to storage that you nominate on your own Device. They are a local export, not a cloud backup service. The Developer neither receives, sees, transmits, nor retains any backup file, and holds no record that one was ever created. Where you subsequently move, copy, share, or upload a backup file — for example to a cloud storage provider, an email account, or a messaging app — that file and its contents pass out of the App's control and into yours, and its security, retention, and confidentiality become governed by that third party's terms and by your own handling of it. See Section 13.

The scheduled automatic backup is not a guaranteed background service and must not be relied upon as your only backup. It depends on the App being opened and on your Device permitting the operation; Android's battery-optimisation, storage-permission, background-activity, and app-standby restrictions vary substantially between manufacturers, Android versions, and power-saving settings, and may delay a scheduled backup, silently prevent it from running, or stop it after a period of non-use. Revoking storage permission, moving or deleting the destination folder, or the destination becoming full or unavailable will likewise cause it to fail. You remain responsible for confirming that scheduled backups are in fact being produced.

If you choose to password-protect a backup, you must keep that password safe. It is not stored by the App, is not transmitted to or held by the Developer, and cannot be reset, bypassed, or recovered by anyone — including us. A password-protected backup whose password has been lost is permanently unreadable and is, for every practical purpose, no backup at all.

Lunaire Accessibility Tools. AspectWise, LuxKeeper and MagniClear have no backup or export feature. Rule Data is stored locally, is not backed up anywhere, and is not transferred to a new Device. If you uninstall the tool, clear its storage, reset your Device, or move to a new Device, your per-app rules will be lost and must be configured again by hand.

(f) No warranty as to backup and restore

Subject to Section 7 (Your Statutory Rights) and to the maximum extent permitted by applicable law, the backup and restore features are provided on the same "as is" and "as available" basis as the rest of the App under Section 8. The Developer does not warrant that a backup will be created successfully or on schedule, that a backup file will be complete, uncorrupted, or readable, that a backup file will remain present or intact in the location you chose, that a backup created by one version of an App will be restorable by another version or on a different Device, or that any restore will succeed. You should verify for yourself that your backups work.

(g) Liability for data loss

Subject to Section 7 (Your Statutory Rights) and to Section 9 (Limitation of Liability), and to the maximum extent permitted by applicable law, the Developer shall have no liability of any kind for the loss, corruption, deletion, inaccessibility, or destruction of Health Data, Rule Data, backup files, or any other data or content stored on or exported from your Device, howsoever caused, including where caused by Device failure, Device loss or theft, operating-system behaviour, third-party software, your own act or omission, or a failure of the App's own backup or restore feature. Subject to the same carve-outs, the same exclusion applies to damage to or corruption of the Device itself, its operating system, or any other app, software, or digital content on the Device, and to the time, effort, or cost of recovering, restoring, or reinstalling any of them, for which your own system and data backups are your protection.

Nothing in this Section 12 excludes or limits any liability that cannot lawfully be excluded or limited — in particular, nothing in this Section affects the carve-outs in Section 9, your statutory rights under the Consumer Rights Act 2015 (including the right to have digital content that is of satisfactory quality, fit for purpose, and as described, and the remedies in ss.42–44), or your rights under s.46 of that Act where digital content supplied by us causes damage to your Device or to other digital content belonging to you. This Section allocates the responsibility for taking backups; it is not an attempt to disclaim liability for our own failure to meet the standards the law requires of us.

(h) Your acknowledgement

By downloading, installing, or using any Lunaire App, you acknowledge and agree that you have read and understood this Section 12; that you are solely responsible for backing up your Device, your system, and your Lunaire data; that Android's automatic backup and transfer functions do not protect your Lunaire data as described in Section 12(b); and that the Developer holds no copy of your data and is therefore unable to recover it for you in any circumstances.

13. 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, magnification) 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.

14. 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 18. 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.

15. 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, 14, and 16 survive termination.

16. 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 15.

(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 14.

(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.

17. 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.

18. 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.
