Terms of Service

These Terms of Service ("Terms") govern your use of the QuakeSight mobile application and website (together, the "Service"), operated by QuakeSight ("we", "us"). By downloading or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Not an early-warning system

QuakeSight is an informational app. It is not an earthquake early-warning system, an emergency service, or a substitute for official guidance. Earthquake data and notifications are based on reports published by third-party seismic networks after an event occurs and may be delayed, revised, inaccurate, or unavailable. Push notifications depend on third-party delivery services and network conditions and are not guaranteed to arrive, or to arrive in time to take any action. You must not rely on the Service for decisions affecting your safety or the safety of others. Always follow the instructions of local civil-protection authorities.

2. License to use the Service

Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable license to use the App on Apple-branded devices that you own or control, as permitted by the App Store Terms of Service. You may not copy, modify, distribute, sell, lease, reverse-engineer, or create derivative works of the Service except as permitted by law.

3. Subscriptions

Some features, including custom earthquake notifications and additional earthquake details, require a paid QuakeSight Pro subscription. Subscriptions are billed to your Apple App Store account and renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription at any time in your App Store account settings. Prices are shown in the App before purchase and may change with notice; changes apply from the next billing period. Except where required by law, purchases are non-refundable — refund requests are handled by Apple under App Store policies.

4. Third-party data

Earthquake information is sourced from third parties, including the United States Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC). We do not control and are not responsible for the accuracy, completeness, or timeliness of this data. Magnitudes, locations, and depths are scientific estimates that are frequently revised after initial publication.

5. Acceptable use

You agree not to:

• use the Service in any way that violates applicable law or these Terms;
• interfere with, disrupt, or place undue load on the Service or its infrastructure;
• attempt to gain unauthorized access to the Service or its related systems;
• scrape, resell, or redistribute data obtained through the Service.

6. Intellectual property

The Service, including its design, code, name, and logo, is owned by us or our licensors and is protected by intellectual property laws. These Terms do not grant you any rights to our trademarks or branding.

7. Privacy

Our Privacy Policy explains what information we collect and how we use it, and forms part of these Terms.

8. Termination

You may stop using the Service at any time by deleting the App. We may suspend or terminate your access to the Service if you breach these Terms or if we discontinue the Service. Sections 1, 4, 9, and 10 survive termination.

9. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE, OR THAT NOTIFICATIONS WILL BE DELIVERED.

10. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES — INCLUDING DAMAGES FOR PERSONAL INJURY, PROPERTY DAMAGE, LOSS OF DATA, OR LOSS OF PROFITS — ARISING FROM OR RELATED TO YOUR USE OF, OR INABILITY TO USE, THE SERVICE, INCLUDING ANY RELIANCE ON EARTHQUAKE DATA OR ANY DELAYED OR UNDELIVERED NOTIFICATION. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

11. Changes to the Service and these Terms

We may modify or discontinue the Service at any time. We may also update these Terms; material changes will be reflected by the "Last updated" date above. Your continued use of the Service after changes take effect constitutes acceptance of the revised Terms.

12. Governing law

These Terms are governed by the laws of the jurisdiction in which we operate, without regard to conflict-of-law principles, and disputes shall be resolved in the courts of that jurisdiction unless applicable consumer law provides otherwise.
