Terms of Use

Effective date: August 2, 2026 · Last updated: August 2, 2026

1. Parties and Acceptance

This End User License Agreement (the “Agreement”) is a legally binding contract between you (“you”, the “User”) and:

Exhalo Inc., 2810 N Church St PMB 99728, Wilmington, DE 19802, United States, email: support@exhalo.app (“we”, “us”, the “Developer”),

and governs your use of the Relief mobile application, including all related features, content, updates, and documentation (collectively, the “App”).

By downloading, installing, or using the App, you confirm that you have read, understood, and agree to be bound by this Agreement and by our Privacy Policy (available at reliefmigraine.app/privacy and within the App), which is incorporated by reference. If you do not agree, do not install or use the App.

You represent that you are at least 16 years old (or the minimum age of digital consent in your jurisdiction) and legally capable of entering into this Agreement.

This Agreement is concluded between you and the Developer only — not with Apple Inc. (“Apple”). See Section 14 for Apple-specific terms required for apps distributed via the App Store.

2. Description of the App

Relief is a self-tracking tool for people who experience migraines and headaches. It allows you to log attacks, symptoms, triggers, and medications; view statistics, patterns, and calendar views; receive informational forecasts of elevated migraine risk based on environmental factors such as weather, atmospheric pressure, and air quality; optionally integrate with Apple Health (e.g., menstrual cycle data); and generate reports you can share with your healthcare provider.

The App operates without user accounts. Your health and tracking data is stored locally on your device, as described in the Privacy Policy.

3. IMPORTANT MEDICAL DISCLAIMER

The App is not a medical device and does not provide medical advice, diagnosis, or treatment.

All content, statistics, correlations, risk forecasts, and insights generated by the App are provided for informational and self-tracking purposes only. They are based on statistical patterns and environmental data and may be inaccurate, incomplete, or inapplicable to your individual condition.
The App is not a substitute for professional medical advice. Never disregard, delay, or discontinue medical care, medication, or advice from a qualified healthcare professional because of anything you see in the App.
Risk forecasts are probabilistic estimates, not predictions of fact. An absence of a warning does not mean an attack will not occur, and a warning does not mean one will.
The App does not monitor emergencies. If you experience a sudden, severe, or unusual headache, or any symptoms suggesting a medical emergency, call your local emergency number immediately.
Always consult your doctor before making decisions about medications or treatment, including decisions informed by the App’s medication-effectiveness statistics.

You acknowledge and agree that you use the App’s informational features at your own discretion and risk.

4. License Grant

Subject to your compliance with this Agreement and, for premium features, payment of the applicable subscription fees, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the App for your personal, non-commercial purposes on any Apple-branded device that you own or control, as permitted by the App Store Terms of Service (including the Usage Rules therein).

The App is licensed, not sold, to you. All rights not expressly granted are reserved by the Developer.

5. License Restrictions

You must not, and must not permit or assist anyone else to:

copy, modify, adapt, translate, or create derivative works of the App, except as expressly permitted by mandatory law;
reverse engineer, decompile, disassemble, or otherwise attempt to derive the App’s source code, algorithms, or prediction models, except to the extent such restriction is prohibited by applicable law;
rent, lease, lend, sell, sublicense, distribute, or otherwise transfer the App or your license to any third party;
remove, obscure, or alter any copyright, trademark, or other proprietary notices;
circumvent, disable, or interfere with the App’s security features, subscription mechanisms, or usage limitations, or access premium features without a valid subscription;
use the App or its output to develop, train, or improve a competing product or service, including any machine-learning model;
use automated means (bots, scrapers) to access the App or its backend services, or place disproportionate load on them;
use the App in violation of applicable law, or in any manner that could harm us, other users, or third parties;
use the App where its failure could lead to death, personal injury, or severe damage (the App is not designed for safety-critical use);
export or re-export the App in violation of applicable export-control and sanctions laws (see also Section 14).

6. Intellectual Property

The App — including its software code, algorithms, prediction models, design, user interface, graphics, icons, text, trademarks (including “Relief” and associated logos), and all other content, excluding Your Data — is owned by the Developer or its licensors and is protected by copyright, trademark, and other intellectual-property laws of the United States, the European Union, and international treaties.

Weather, air-quality, and other environmental data displayed in the App is sourced from third-party providers and/or our backend and is provided for display within the App only; you may not extract, redistribute, or commercially exploit it.

No provision of this Agreement transfers any ownership of intellectual property to you.

7. Your Data

“Your Data” means the entries, logs, notes, and other content you create in the App, and the Apple Health data you allow the App to read. You retain all rights to Your Data. We claim no ownership of it.
Your Data is stored locally on your device and is not transmitted to our servers, as detailed in the Privacy Policy. Consequently, we cannot access, recover, or restore Your Data. You are solely responsible for maintaining device backups (e.g., iCloud or local backups) if you wish to preserve Your Data.
You are responsible for the accuracy of what you log; the App’s statistics are only as reliable as the data you enter.
We may generate and use aggregated, anonymized statistics derived from app-usage analytics to operate and improve the App, as described in the Privacy Policy. Such statistics contain no personal data and do not include the contents of Your Data.

8. Subscriptions, Free Trial, and Payments

Free tier and premium features. Certain core features (including basic logging and statistics) are available free of charge. Advanced features require a paid auto-renewing subscription (“Premium”). The specific features, prices, billing periods, and any free-trial terms are presented in the App at the point of purchase and may vary by region.
Billing via Apple. Subscriptions are purchased exclusively through your Apple ID as in-app purchases. Payment is charged to your Apple ID upon confirmation of purchase (or after any free trial ends). We do not receive or store your payment card details.
Auto-renewal. Subscriptions renew automatically for the same period unless auto-renewal is turned off at least 24 hours before the end of the current period. Your Apple ID is charged for renewal within 24 hours before the current period ends.
Free trial. Where offered, the free trial converts into a paid subscription automatically unless cancelled at least 24 hours before the trial ends. Any unused portion of a free trial is forfeited when you purchase a subscription. Trial eligibility may be limited to one per user/Apple ID.
How to cancel. Manage or cancel in iOS Settings → [your name] → Subscriptions → Relief, or through the App Store app. Deleting the App does not cancel a subscription.
Effect of cancellation. Cancellation takes effect at the end of the current paid period; until then, Premium remains active. After expiry: (a) Premium features are disabled; (b) you retain access to the core free features, including your logging history and basic statistics; and (c) Your Data remains untouched on your device — nothing is deleted or withheld because a subscription ends.
Price changes. We may change subscription prices prospectively. Apple will notify you of price increases as required, and, where applicable law or Apple’s rules require, an increase will not apply without your consent; if you do not agree, the subscription will not renew.
Refunds. Purchases are processed by Apple, and refunds are governed by Apple’s terms. To request a refund, use reportaproblem.apple.com or contact Apple Support. To the maximum extent permitted by law, we cannot issue refunds for App Store purchases directly. Statutory rights of consumers, including any mandatory withdrawal rights under EU consumer law, remain unaffected; by starting immediate access to digital content you may lose the 14-day withdrawal right to the extent permitted by law, as disclosed at purchase.
Taxes. Prices shown by Apple include applicable VAT where required.

9. Updates, Changes, and Availability

We may release updates, patches, and new features at our discretion. Updates may be required for continued use; the App may cease functioning correctly on outdated OS versions or without updates.
We may modify, suspend, or discontinue the App or any feature (including backend-dependent features such as weather-based forecasts) in whole or in part. For material degradations affecting paid features during an active subscription period, EU consumer-protection rules on conformity of digital content apply, and you may have statutory remedies.
Backend-dependent features require an internet connection and the availability of third-party data sources; we do not guarantee uninterrupted availability.

10. Third-Party Services

The App relies on third-party services, including Apple (distribution, payments, HealthKit), analytics and attribution providers, and weather/air-quality data sources, as listed in the Privacy Policy. Your use of Apple Health is additionally governed by Apple’s terms. We are not responsible for third-party services, their accuracy (including weather and air-quality data), or their availability.

11. Disclaimer of Warranties

To the maximum extent permitted by applicable law, the App is provided “as is” and “as available”, without warranties of any kind, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. Without limiting the foregoing, we do not warrant that:

the App will be error-free, secure, or uninterrupted;
forecasts, statistics, or correlations will be accurate or useful for your individual situation;
defects will be corrected, or that the App is free of harmful components.

Consumer-rights carve-out: nothing in this Agreement excludes or limits warranties, guarantees, or remedies that cannot be excluded or limited under the mandatory laws of your country of residence, including the conformity requirements for digital content under EU Directive 2019/770 as implemented in national law.

12. Limitation of Liability

To the maximum extent permitted by applicable law:

we shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, revenue, goodwill, or data (including loss of Your Data stored on your device), arising out of or related to this Agreement or the App, even if advised of the possibility of such damages;
our total aggregate liability arising out of or relating to this Agreement or the App shall not exceed the greater of (a) the amounts you paid for the App in the twelve (12) months preceding the event giving rise to the claim, and (b) EUR 50;
we are not liable for decisions you make — medical, lifestyle, or otherwise — in reliance on the App’s informational content (see Section 3).

Nothing in this Agreement excludes or limits liability for: death or personal injury caused by our negligence; willful misconduct or gross negligence where such limitation is prohibited; fraud; or any other liability that cannot be excluded or limited under mandatory applicable law, including mandatory consumer-protection law of your habitual residence.

13. Indemnification

To the extent permitted by applicable law (and, for consumers, only to the extent such obligations are enforceable against consumers in your jurisdiction), you agree to indemnify and hold the Developer harmless from claims, damages, and reasonable costs (including legal fees) arising from your breach of this Agreement or your unlawful use of the App.

14. Apple App Store Terms (Required Provisions)

Because the App is distributed via the Apple App Store, the following applies:

Acknowledgement. This Agreement is between you and the Developer only, not Apple. The Developer, not Apple, is solely responsible for the App and its content.
Scope of license. Your license is limited to use of the App on Apple-branded products that you own or control, as permitted by the Usage Rules in the App Store Terms of Service, except that the App may be accessed by other accounts associated with you via Family Sharing or volume purchasing.
Maintenance and support. The Developer is solely responsible for providing any maintenance and support for the App. Apple has no obligation to furnish any maintenance or support services.
Warranty. In the event of any failure of the App 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 maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App; any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to a warranty are the Developer’s sole responsibility.
Product claims. The Developer, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession/use of it, including: (i) product-liability claims; (ii) claims that the App fails to conform to applicable legal or regulatory requirements; and (iii) claims arising under consumer protection, privacy, or similar legislation, including in connection with the App’s use of HealthKit.
Intellectual-property claims. In the event of any third-party claim that the App or your possession and use of it infringes that third party’s intellectual-property rights, the Developer, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of such claim.
Legal compliance. You represent and warrant that (i) you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
Developer contact: Exhalo Inc., 2810 N Church St PMB 99728, Wilmington, DE 19802, United States — support@exhalo.app.
Third-party terms. You must comply with applicable third-party terms of agreement when using the App (e.g., your wireless data agreement).
Third-party beneficiary. Apple and Apple’s subsidiaries are third-party beneficiaries of this Agreement, and upon your acceptance, Apple will have the right (and will be deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary.

15. Term and Termination

This Agreement is effective from your first download or use of the App and continues until terminated.
By you: you may terminate at any time by deleting the App from all your devices (and cancelling any active subscription per Section 8.5).
By us: we may terminate or suspend your license immediately if you materially breach this Agreement (in particular Sections 5 or 14.7), with notice where required by law and, where the breach is remediable, after a reasonable opportunity to remedy it for consumers.
Effect of termination: the license granted in Section 4 ends and you must cease using and delete the App. Because Your Data is stored only on your device, deleting the App also deletes Your Data (export it first via the App’s report/export function if you wish to keep it — see the Privacy Policy). Sections 3, 6, 7, 11, 12, 13, 14, 16, and 17 survive termination. Termination does not entitle you to a refund of prepaid subscription fees except where required by mandatory law or Apple’s policies.

16. Governing Law, Consumer Protections, and Disputes

This Agreement is governed by the laws of the State of Delaware, United States, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods (CISG).
If you are a consumer residing in the EU/EEA, the UK, or another jurisdiction with mandatory consumer protections, this choice of law does not deprive you of the protection of mandatory provisions of the law of your country of habitual residence, and you may bring proceedings in the courts of that country. Nothing in this Agreement limits your statutory rights, including conformity rights for digital content under EU Directive 2019/770 as implemented in national law.
Out-of-court resolution. We encourage you to contact support@exhalo.app first — most issues are resolved this way. EU consumers may also use the EU Online Dispute Resolution platform at ec.europa.eu/consumers/odr. We do not undertake to participate in out-of-court dispute-resolution proceedings before a consumer arbitration body.
For users who are not consumers, the state and federal courts located in Delaware, United States, have exclusive jurisdiction, and each party consents to their venue and personal jurisdiction.

17. Miscellaneous

Entire agreement. This Agreement, together with the Privacy Policy and the terms presented at the point of any purchase, constitutes the entire agreement regarding the App and supersedes prior understandings.
Changes to this Agreement. We may amend this Agreement for valid reasons (legal changes, new features, security, business changes). Material changes will be announced in the App and/or on our website with reasonable advance notice; the amended version applies from the stated effective date. If you do not agree, stop using the App and cancel any subscription before the changes take effect; where required by law, we will seek your active consent.
Severability. If any provision is held invalid or unenforceable, the remainder stays in effect, and the invalid provision is replaced by a valid one closest to its economic intent.
No waiver. Failure to enforce a provision is not a waiver of it.
Assignment. You may not assign this Agreement. We may assign it in connection with a merger, acquisition, or sale of assets, subject to your statutory rights.
Force majeure. We are not liable for failures caused by events beyond our reasonable control.
