Effective Date: 2026-08-05
These Terms of Use (“Terms”) govern your use of the MigraineLog mobile application (the “Application”), developed and operated by Individual Entrepreneur VALERI YURII MASLENNIKOV (“Service Provider”, “we”, “us”). By downloading, installing, or using the Application, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the Application.
MigraineLog is a personal headache and migraine diary. The Application allows you to log headache episodes (severity, pain locations, triggers, dates), track medication intake, view statistics, export PDF reports, and view weather data that may correlate with your headache patterns.
Certain features of the Application are available free of charge. Additional features (“Premium Features”) — including weather insights, trigger insights and experiments, and PDF report export — require a paid subscription (see Section 4).
The Application is not a medical device and does not provide medical advice, diagnosis, or treatment. All content and features of the Application, including statistics, insights, experiments, and weather-related information, are provided for informational and self-tracking purposes only. They must not be used as a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of a qualified healthcare provider with any questions regarding a medical condition, your medication, or your treatment. Never disregard professional medical advice or delay seeking it because of information presented in the Application.
The Service Provider grants you a limited, non-exclusive, non-transferable, revocable license to use the Application for your personal, non-commercial purposes on Apple-branded devices that you own or control, in accordance with these Terms and the App Store Terms of Service.
You may not:
copy, modify, distribute, sell, lease, or sublicense the Application or any part of it;
reverse-engineer, decompile, or attempt to extract the source code of the Application, except to the extent permitted by applicable law;
use the Application in any unlawful manner or for any unlawful purpose;
circumvent, disable, or interfere with security-related or subscription-related features of the Application.
Premium Features are provided through an auto-renewable subscription (“MigraineLog Premium”), available in monthly and yearly plans. Current prices are displayed inside the Application and in the App Store before purchase and may vary by region and currency.
Payment is charged to your Apple ID account at confirmation of purchase.
The subscription automatically renews unless it is cancelled at least 24 hours before the end of the current billing period.
Your account is charged for renewal within 24 hours prior to the end of the current period, at the price of the plan in effect at that time.
You can manage or cancel your subscription at any time in your App Store account settings (Settings → your name → Subscriptions on your device). Deleting the Application does not cancel your subscription. Upon cancellation, you retain access to Premium Features until the end of the paid period; no partial refunds are provided for the unused portion of a billing period.
Purchases are processed by Apple. Refund requests are handled by Apple in accordance with the App Store Terms of Service; the Service Provider is unable to issue refunds directly. To request a refund, visit reportaproblem.apple.com.
The Service Provider may change subscription prices. Any price change will apply no earlier than the next billing period, and you will be notified in accordance with App Store rules with an opportunity to cancel before the change takes effect.
If a free trial or introductory offer is available, its terms and duration will be presented before purchase. Any unused portion of a free trial period is forfeited when you purchase a subscription.
Your diary records (headaches, medications, triggers) are stored locally on your device. You are responsible for maintaining backups of your data (for example, by using the export feature). Uninstalling the Application permanently deletes locally stored data; the Service Provider cannot recover it. The processing of personal data is described in the Privacy Policy.
The Application, including its design, graphics, text, and code, is the property of the Service Provider and is protected by applicable intellectual property laws. These Terms do not grant you any rights to the Application other than the limited license in Section 3.
The Application relies on third-party services, including Apple (distribution and payments), RevenueCat (subscription management), Open-Meteo (weather data), and Expo (application infrastructure). The Service Provider is not responsible for the availability or performance of third-party services. You agree to comply with all applicable third-party terms of agreement (including the App Store Terms of Service) when using the Application. Your use of third-party services may also be subject to their own terms and privacy policies.
THE APPLICATION IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. THE SERVICE PROVIDER DOES NOT WARRANT THAT THE APPLICATION WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT WEATHER DATA, STATISTICS, OR INSIGHTS WILL BE ACCURATE OR RELIABLE.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE PROVIDER SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OR INABILITY TO USE THE APPLICATION. IN ANY EVENT, THE SERVICE PROVIDER'S TOTAL AGGREGATE LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE SUBSCRIPTION DURING THE TWELVE (12) MONTHS PRECEDING THE CLAIM. NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED UNDER APPLICABLE LAW.
These Terms are concluded between you and the Service Provider only, not with Apple Inc. (“Apple”). Apple is not responsible for the Application or its content. The Service Provider, not Apple, is solely responsible for the Application and for providing any maintenance and support services with respect to it, as specified in these Terms or as required under applicable law; Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the Application. In the event of the Application's failure to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the Application (if any); to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the Application. Apple is not responsible for addressing any claims by you or a third party relating to the Application, including product liability claims, claims that the Application fails to conform to legal or regulatory requirements, and consumer protection claims. In the event of any third-party claim that the Application, or your possession and use of the Application, infringes that third party's intellectual property rights, the Service Provider, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of such claim. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties.
These Terms are effective until terminated. Your rights under these Terms terminate automatically if you fail to comply with them. The Service Provider may suspend or discontinue the Application (or any part of it) at any time. Sections 2, 6, 8, 9, and 12 survive termination.
These Terms are governed by the laws of the country of registration of the Service Provider, without regard to conflict-of-law principles, except where mandatory consumer protection laws of your country of residence provide otherwise.
The Service Provider may update these Terms from time to time. Changes will be published on this page with an updated effective date. Your continued use of the Application after changes take effect constitutes acceptance of the updated Terms.
For any questions, inquiries, or complaints regarding these Terms or the Application, please contact the Service Provider:
