Terms of Service
Effective date: July 12, 2026
These Terms of Service (the "Terms") apply between the developer ("we", "us") of the Oria macOS app (the "App") and everyone who uses the App ("you", the "user"). By downloading, installing, or using the App, you agree to be bound by all provisions of these Terms. If you do not agree, please do not use the App.
1. Who we are
The App is developed and operated by an individual developer. For inquiries about these Terms, contact support@yururon.app.
2. About the App
The App is a reading-support app for macOS that lets you read book, paper, and technical-document files you import yourself (EPUB / PDF / Markdown), assisted by translation features and AI chat features (such as summaries and questions).
The App itself does not distribute or provide books, papers, or other content. You are responsible for obtaining and importing the documents you read.
3. Conditions of use
- The App is not primarily directed at children of any specific age group.
- If you are a minor, please use the App with the consent of a parent or legal guardian and under their supervision.
- You must comply with these Terms and applicable laws.
- You must have an environment that meets the App's requirements, including the required macOS version and access to Apple services such as iCloud.
4. User content (imported documents)
- All rights in the document files you import into the App and their content ("User Content") remain with you or the rightful owner. We acquire no rights in your User Content.
- You may import only documents that you have the lawful right to use.
- When you use the cloud AI features, portions of the document's body text are sent to an external AI provider (see the Privacy Policy for details). You may use the cloud AI features only with documents you have the right to transmit in this way.
- You are responsible for managing and backing up your own User Content.
5. AI-generated content (important)
The translations, summaries, answers, and other output produced by the App's translation and AI chat features are generated automatically by AI. By using the App, you agree to the following:
- The output may contain errors, inaccuracies, deviations from the original text, exaggerations, or omissions.
- Always check the original text yourself before making important decisions or quoting the output.
- AI-generated content does not constitute medical, legal, tax, investment, or other professional advice. Do not rely on it as the basis for decisions in these areas.
- We make no guarantees regarding the accuracy, completeness, or fitness for a particular purpose of AI-generated content.
6. Intellectual property
- All rights in the App itself (UI, logos, code, etc.) and in materials we own belong to us or to third parties who have licensed them to us.
- Ownership of User Content is as set out in "4. User content".
- You may use the AI-generated content produced by the App (translations, summaries, answers) at your own responsibility. Note, however, that the rights of the owner of the original document may extend to AI-generated content derived from it. If you publish or redistribute translations or summaries, follow the license and permission terms of the original rights holder.
- We do not guarantee that AI-generated content gives rise to copyright or other rights, or that it does not infringe the rights of third parties.
7. Prohibited conduct
When using the App, you must not:
- Violate laws, public order and morals, or these Terms
- Infringe the intellectual property, privacy, reputation, or other rights of us or any third party
- Import documents you have no lawful right to use, or send such documents to the cloud AI features
- Interfere with the operation of the App (excessive requests, automated access, attacks on servers, reverse engineering, etc.)
- Circumvent rate limits or other technical restrictions
- Copy, resell, or distribute at scale the App's source code or API endpoints without permission
- Engage in any other conduct we reasonably deem inappropriate
If you violate these Terms, or where there is a risk of abuse, security issues, or legal violations, or where operationally necessary, we may restrict your use of the cloud AI features or other App features without prior notice.
8. Subscriptions (Oria Premium)
The App offers a paid auto-renewing subscription, Oria Premium.
- Plans: A monthly plan is offered. The plan name, price, and billing period are displayed on the in-app purchase screen before you complete a purchase.
- Benefits: With Premium, you can use AI chat and translation powered by cloud AI (OpenAI / Google Gemini). On the free plan, you can use features powered by on-device AI. Benefits may change as the service evolves.
- Billing: Payment is charged to your Apple ID account at confirmation of purchase. All billing, payment, and renewal processing is handled by Apple (the App Store); we never receive payment details such as your credit card number.
- Auto-renewal: Subscriptions renew automatically, and the renewal fee is charged, unless auto-renewal is turned off at least 24 hours before the end of the current period.
- Cancellation and management: You can turn off auto-renewal or cancel at any time from your App Store account settings (or "Manage Subscription" in the App). Cancellation takes effect at the next renewal date.
- Price changes: If we change prices, we will give advance notice in accordance with Apple's procedures and obtain your consent where required.
- Refunds: Refunds after purchase are subject to Apple's policies. As a rule, no refunds are provided for unused periods.
- Usage limits: The cloud AI features may be subject to reasonable rate limits (such as caps on the number of requests) to keep the service stable.
9. Changes to and termination of the service
We may change, add to, or remove App content, or suspend or terminate all or part of the App, where necessary for maintenance, incident response, security, compliance with laws or App Store requirements, changes to or discontinuation of third-party services (including AI providers), or other operational reasons. Where possible, we will notify you in advance or afterwards within the App or by other appropriate means.
The App is a service continuously improved by an individual developer, and its features, displayed content, supported environments, available AI models, and period of availability may change. Unless we are at fault, we are not liable for damages you incur as a result of such changes, suspension, or termination.
10. Disclaimer of warranties
The App is provided "as is" and "as available". We make no warranties of any kind, express or implied, regarding the App and all features and content provided through it (including AI-generated content), including but not limited to:
- Accuracy, completeness, currency, or usefulness
- Merchantability or fitness for a particular purpose
- Non-infringement of third-party rights
- Uninterrupted or error-free operation
- Freedom from security vulnerabilities
- That data (your library, translation results, etc.) will not be lost
11. Limitation of liability
Unless we are at fault, we are not liable for damages you incur arising out of or in connection with your use of, or inability to use, the App (including reliance on AI-generated content and loss of data).
If you incur damages due to our slight negligence, our liability is limited to ordinary and direct damages actually incurred by you, and we are not liable for lost profits, loss of data, business interruption, damage to reputation, or indirect, special, or consequential damages.
Where we are liable due to slight negligence, our total liability is capped at JPY 1,000.
The above limitations do not apply where damages result from our willful misconduct or gross negligence.
Some jurisdictions do not allow the above disclaimers of warranty or limitations of liability. In such cases, these provisions apply to the extent permitted by applicable law.
12. Third-party services
The App uses third-party services such as Apple iCloud, the Apple App Store, Cloudflare, OpenAI, Google (Gemini API), and TelemetryDeck. The operation, content, and conditions of these third-party services are governed by the respective providers' terms of service and privacy policies.
13. Privacy
The handling of information obtained from users is described in our separate Privacy Policy. By using the App, you also agree to the Privacy Policy.
14. Governing law and jurisdiction
These Terms are governed by the laws of Japan. Any dispute arising between you and us in connection with these Terms or the App shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance.
15. Changes to these Terms
We may amend these Terms where the amendment is in the general interest of users, or where it is reasonable in light of the necessity of the amendment, the appropriateness of the amended content, and other circumstances.
When we amend these Terms, we will announce the amended content and its effective date within the App, on our website, or by other appropriate means. For material changes that are disadvantageous to users, we will provide notice with a reasonable advance period. If you continue to use the App after a change takes effect, you are deemed to have agreed to the amended Terms.
16. Severability
If any provision of these Terms is held invalid or unenforceable, the validity and enforceability of the remaining provisions shall not be affected.
