Last updated: 2026-10-02 (effective the same day; Sections 5 and 13 revised)

These Terms of Use ("Terms") govern your use of the Myriad Saga application ("the App") for iOS and Android, developed by ODiN Soft ("we", "us", or "the Service Provider"). By downloading, installing, or using the App, you agree to be bound by these Terms.

1. Acceptance of Terms

By accessing or using the App, you confirm that you have read, understood, and agree to these Terms. If you do not agree, please do not use the App.

2. Description of Service

Myriad Saga is a roguelike TRPG (tabletop role-playing game) that uses generative AI to create game content including events, scenarios, characters, and images. The App is provided as a Freemium service.

3. User Accounts

• You may create an account using email/password, Google Sign-In, Apple Sign-In, or anonymous authentication.
• You are responsible for maintaining the confidentiality of your account credentials.
• You must be at least 13 years old to use the App.

4. AI-Generated Content

• The App uses third-party AI services (xAI Grok, fal.ai, Google Gemini) to generate game content.
• AI-generated content may occasionally produce unexpected or inaccurate results. We do not guarantee the accuracy, quality, or appropriateness of AI-generated content.
• You agree not to use the App to intentionally generate content that is illegal, harmful, hateful, sexually explicit, or otherwise objectionable.

5. User-Generated Content and AI Output

• User input text (character names, prompts, world settings, scenario summaries, and any other text you directly enter) remains your property.
• AI-generated output (images, text, stories, cards, character graphics, and any other content produced through the App's systems based on your input): ODiN Soft does not claim ownership of AI-generated output. In turn, you agree not to assert copyright or other rights (including moral rights) over AI-generated output against ODiN Soft or other users.
• You grant ODiN Soft a royalty-free, worldwide, perpetual, sublicensable, and modifiable license to use AI-generated output for any purpose, including but not limited to operating and improving the App, marketing and promotion, advertising, app store listings, social media posts, and our other business activities.
• For your input text and any content you publish (share) within the App, you grant ODiN Soft and other users a royalty-free, non-exclusive, worldwide, sublicensable, and modifiable license to use such content for:
  • Operating App features (including sharing, AI-driven derivative generation, search, display, gacha, etc.)
  • Marketing and promotion of the App and ODiN Soft
• You represent and warrant that the content you submit does not infringe any third-party copyrights, trademarks, rights of publicity, privacy rights, or other rights, and you agree to indemnify us and any affected third party for any losses arising from breach of this warranty.
• You may freely use AI-generated output within the App and for personal, non-commercial purposes (e.g., posting to social media). For commercial use, please contact us separately.
• Where a feature of the App provides specific terms that permit broader use of AI-generated output than this Section, those terms take precedence.
• We reserve the right to unpublish or remove any AI-generated content (including but not limited to cards, characters, and equipment) published within the App, without prior notice, if we determine it may infringe third-party rights, violate public order or morals, or is otherwise inappropriate. We are not liable for any loss resulting from such action.

6. In-App Purchases and Subscriptions

• The App offers in-app purchases (gem packages) and subscriptions (Myriad Saga Pass).
• All purchases are processed through Apple App Store or Google Play Store and are subject to their respective terms.
• Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current billing period.
• You can manage or cancel subscriptions through your device's subscription settings.
• Refunds are handled by Apple or Google according to their respective refund policies.

7. Virtual Currency

• Gems are virtual currency used within the App. They have no real-world monetary value and cannot be exchanged for cash.
• We reserve the right to modify gem pricing, rewards, and the virtual economy at any time.
• Purchased gems are non-transferable between accounts.

13. Changes to These Terms

We may change these Terms without your individual consent in either of the following cases:

• The change is in the general interest of users.
• The change does not conflict with the purpose of these Terms and is reasonable in light of the necessity of the change, the appropriateness of the changed content, and other circumstances relating to the change.

When we change these Terms, we will announce the changed Terms and their effective date before the effective date, by posting them on this page, through in-app notices, or by other appropriate means.
