1. Not medical advice

Migraine Sentry is a tracking and insights tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Forecasts, trigger rankings, insights, nudges and reports are informational only, are probabilistic in nature, and may be incomplete or wrong. Never disregard professional medical advice, or delay seeking it, because of something the app showed you. If you believe you are experiencing a medical emergency, contact emergency services immediately.

2. License

We grant you a personal, non-exclusive, non-transferable, revocable license to use the app on Apple devices you own or control, as permitted by the App Store terms. Apple's standard Licensed Application End User License Agreement applies where not superseded by these terms.

3. Subscriptions

Some features may require a paid subscription, processed by Apple. Prices, trial terms and billing periods are shown in the app before purchase. Subscriptions renew automatically unless cancelled in your App Store account settings at least 24 hours before the period ends. Refunds are handled by Apple under App Store policies.

4. Acceptable use

You agree not to reverse-engineer, resell, or misuse the app, and not to use it in any way that violates applicable law.

5. Your data

Your health data stays on your device, as described in the Privacy Policy. You are responsible for your device's security and backups; deleting the app deletes your data.

6. Disclaimers

The app is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose and accuracy of information. We do not warrant that forecasts or insights will be accurate, that the app will be uninterrupted or error-free, or that any health outcome will result from its use.

7. Limitation of liability

To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential or exemplary damages arising from your use of the app, and our total liability for any claim shall not exceed the amount you paid for the app in the twelve months before the claim arose. Nothing in these terms limits liability that cannot be limited by law.

8. Changes to the app or terms

We may modify or discontinue features, and may update these terms; continued use after an update constitutes acceptance. Material changes will be flagged in the app or on this page.
