5. User-Generated Content

The App allows you to submit user-generated content ("UGC"), including display names, Player Finder contact notes, league narrative notes, store submissions, and troupe names.

You retain all rights you hold in your UGC. By submitting UGC, you grant Tinkavu LLC a worldwide, non-exclusive, royalty-free license to store, display, and use that content within the App and its backend services solely for the purpose of operating and providing the App to you and other users. We will not use your UGC for any other purpose.

You represent and warrant that:

  • You have the right to submit the content.
  • The content does not infringe any third-party intellectual property rights, privacy rights, or other legal rights.
  • The content complies with these Terms.

Content moderation: Free-text fields are subject to automated moderation (via OpenAI's moderation API) and, in cases of flagged content, human review. We may remove or decline to publish content that violates these Terms. Repeated violations may result in account suspension or termination.

6. Fan-Made App & Intellectual Property Disclaimer

All Moonstone trademarks, trade names, game rules, character names, artwork, and related intellectual property are the exclusive property of Goblin King Games. Use of these marks and content in the App is for fan informational and game-companion purposes only, under permission granted by Goblin King Games as of the date noted in the App's "About" screen.

Permission scope: The App uses images and information from Goblin King Games' public websites (moonstonethegame.com and shop.moonstonethegame.com) with permission.

7. Third-Party Services

The App integrates third-party services, including Supabase (database and authentication), OpenAI (content moderation), LocationIQ (geocoding), OpenFreeMap/OpenStreetMap (map tiles), and Google (authentication and Drive export). Your use of these services is subject to their respective terms of service and privacy policies.

We are not responsible for the content, practices, or policies of any third-party service. Links or integrations with third-party services do not constitute our endorsement of those services.

8. No Subscriptions or Payments

The App is free to download and use. There are no in-app purchases, subscriptions, or paid features at this time. If we introduce paid features in the future, we will update these Terms and clearly disclose all pricing and billing terms before any purchase.

Some jurisdictions do not allow the exclusion or limitation of certain types of liability; in those jurisdictions our liability is limited to the greatest extent permitted by law.

12. Termination

By you: You may stop using the App at any time. You may delete your account via Settings → Delete Account. Uninstalling the App does not delete your account data.

By us: We may suspend or terminate your access to the App at any time, with or without notice, if we determine that you have breached these Terms, if required by law, or if we discontinue the App.

Effect of termination: On termination of your license, your right to use the App ceases immediately. The following sections survive termination and remain in full force: Section 3 (License Restrictions), Section 5 (User-Generated Content — the license you granted remains for content retained consistent with our Privacy Policy), Section 6 (IP Disclaimer), Section 10 (Disclaimers), Section 11 (Limitation of Liability), Section 12 (Termination — this sentence), Section 13 (Governing Law), and Section 14 (General).

13. Governing Law & Dispute Resolution

These Terms are governed by and construed in accordance with the laws of the State of Georgia, without regard to its conflict-of-law principles. Any dispute, claim, or controversy arising out of or relating to these Terms or the App that is not resolved informally shall be subject to the exclusive jurisdiction of the state and federal courts located in Cobb County, Georgia.

Before initiating any formal proceeding, we encourage you to contact us at privacy@extraturngames.com to attempt to resolve the dispute informally. We will make a good-faith effort to resolve any complaint or dispute within 30 days.

Nothing in this section limits your rights to bring claims before a consumer protection authority or supervisory authority in your jurisdiction.

14. General

  • Severability: If any provision of these Terms is held to be unenforceable, the remaining provisions continue in full force.

  • No third-party beneficiaries: These Terms do not create any third-party beneficiary rights, except as expressly stated (see §6 regarding Goblin King Games' retained IP rights).
