This Privacy Policy describes how the developer (“we”, “us”) collects, uses, and shares information when you use the Yururon iOS app (the “App”). By using the App, you agree to the practices described below.
The App is developed and operated by an individual developer. For privacy-related inquiries, contact miokato07@gmail.com.
If disclosure of the provider’s name, address, or similar information is required under Japan’s Act on the Protection of Personal Information or other applicable laws, we will respond without undue delay upon request, after reasonable identity verification.
We collect only the information needed to provide the App’s features.
When you sign in with Sign in with Apple, we receive:
You can use most of the App without signing in. Sign-in is required only for bookmarks and push notifications.
When you are signed in, the following data is associated with your account:
If you grant App Tracking Transparency (ATT) permission, the App allows Google AdMob to access the Identifier for Advertisers (IDFA) to deliver more relevant ads on the paper detail screen. If you decline, ads are still shown but are not personalized using your IDFA.
Even if you do not grant ATT permission, Google may process information needed for ad delivery, fraud prevention, impression measurement, and similar purposes. For details about Google’s handling of information, please review Google’s Privacy Policy and applicable AdMob policies.

We do not sell your personal information.
The App relies on the following third-party services. Each operates under its own privacy policy.
| Service | Purpose | Provider’s policy |
|---|---|---|
| Sign in with Apple | Authentication | https://www.apple.com/legal/privacy/ |
| Supabase | Backend database and authentication | https://supabase.com/privacy |
| Google AdMob | In-app advertising | https://policies.google.com/privacy |
| Apple Push Notification service | Delivering notifications | https://www.apple.com/legal/privacy/ |
We send information to the third-party services above only to the extent necessary to provide the App. Each third-party service applies its own privacy policy and contractual terms to protect personal information. When selecting third-party services, we check that user data will be handled in a manner consistent with this Policy, applicable laws, and App Store requirements.
Paper content shown in the App is fetched from arXiv and other external sources by our backend. These external sources do not receive any of your personal data from the App.
Paper summaries and concept artwork shown in the App are generated by AI on our backend before delivery. The AI generation process uses only the public paper metadata (title, abstract, etc.) — your personal data is never sent to any AI service.
You can:
You may have the right under applicable laws to request access to, correction of, addition to, deletion of, suspension of use of, or suspension of third-party provision of your personal data held by us. To make such a request, please contact us at the address above. We will respond in accordance with applicable laws after reasonable identity verification.
Depending on where you live, you may also have rights under applicable laws (such as GDPR or CCPA) to access, correct, or port your personal data. Contact us to exercise these rights.
The App is not primarily directed to children of any specific age group. If you are a minor, you must use the App with the consent of your parent or legal guardian and under their supervision.
We do not knowingly collect more personal information from children than is necessary to provide the App. If a parent or legal guardian wishes to review, delete, or suspend the use of a child’s personal information, or if you believe a child’s information is included in the App, please contact us. We will respond in accordance with applicable laws after reasonable identity or guardian verification.
The third-party services used by the App may process data in countries or regions outside Japan. For example, account information, information needed for ad delivery, and information needed for push notifications may be processed in regions where service providers such as Supabase, Google, and Apple operate.
We use these third-party services only to the extent necessary to provide the App, after reviewing their publicly available privacy policies, security information, contractual terms, and related materials. If you have questions about international data transfers, please contact us.
We use industry-standard measures (including TLS in transit and access control on the backend) to protect your data. However, no service can guarantee perfect security.
We may update this Privacy Policy from time to time. The “Effective date” above will reflect the latest revision. Material changes will be announced in the App or via email where appropriate.
