Price Changes

We may change subscription or in-app purchase prices at any time. Existing subscribers will be notified at least 30 days before any price increase takes effect for their next renewal period. Continued subscription renewal after a price change constitutes acceptance of the new price.

5. Updates and Modifications

We may release updates to the App from time to time, including bug fixes, new features, content changes, and performance improvements. Some updates may be required to continue using the App. Updates are subject to this EULA unless a separate agreement is provided.

We reserve the right to modify, suspend, or discontinue any feature of the App at any time, with or without notice. Game mechanics, scoring algorithms, leaderboard calculations, badge requirements, and other gameplay elements may change as the App evolves.

6. Data and Privacy

Your use of the App is also governed by our Privacy Policy, which describes how we collect, use, and share your information. By using the App, you consent to our data practices as described in that policy.

The App collects location data (city, state, and precise coordinates) to fetch weather forecasts from the National Weather Service, deliver county-level predictions, match you to severe weather events, and place you on location-based leaderboards. You provide this information at onboarding and can change it in Settings. The App does not track your real-time location or maintain a location history.

7. Third-Party Services

The App uses the following third-party services to operate:

• Supabase — database and authentication
• RevenueCat — subscription and purchase management
• OneSignal — push notifications
• Sentry — crash diagnostics
• PostHog — anonymous product analytics (opt-out available in Settings)

These services are governed by their own terms and privacy policies. We are not responsible for the practices or availability of third-party services.

8. Weather Prediction Disclaimer

RivalWx is a game. It is not a weather service.

The App displays weather data sourced from public government agencies, but it is designed for entertainment and educational purposes only. Do not rely on RivalWx for life-safety decisions during severe weather events. Always follow official guidance from the National Weather Service, local emergency management agencies, and local authorities.

Weather data displayed in the App is provided “as is” from third-party public sources. We do not independently verify forecast accuracy and make no warranties about the completeness, reliability, or timeliness of any weather information shown.

9. Disclaimer of Warranties

The App is provided “as is” and “as available” without warranties of any kind, whether express, implied, or statutory. Isobar Works LLC disclaims all warranties, including but not limited to implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

We do not warrant that the App will be uninterrupted, error-free, secure, or free of viruses or other harmful components. Leaderboard rankings, scores, streaks, badges, and other gameplay elements may be affected by server outages, data-source interruptions, scoring delays, or software bugs.

10. Limitation of Liability

To the maximum extent permitted by applicable law, Isobar Works LLC and its officers, employees, agents, and affiliates shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of or inability to use the App, including but not limited to loss of data, loss of goodwill, device damage, or lost profits, regardless of the theory of liability.

Our total aggregate liability for all claims arising out of or related to this EULA or your use of the App shall not exceed the greater of (a) the amount you actually paid us through in-app purchases or subscriptions in the twelve (12) months preceding the claim, or (b) fifty dollars ($50.00).

11. Indemnification

You agree to indemnify, defend, and hold harmless Isobar Works LLC and its officers, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to your use of the App, your violation of this EULA, or your violation of any rights of a third party.
