  • Reading Data: Favorites, saved books, vocabulary lists, and AI-generated reading content stored to sync across devices.

  • Create and manage your account

  • Personalize your reading and learning experience

  • Manage subscriptions and access to premium features

  • Store and display your scanned books with furigana and dictionary support

  • Improve and maintain the Yomoyo app

  • Ensure security and prevent unauthorized access

3. Third-Party Services

We work with trusted third-party providers to operate Yomoyo:

  • Firebase Authentication: For account creation and login

  • Firebase Firestore and Storage: For storing reading content, favorites, and user data

  • RevenueCat: For managing subscription payments

  • OpenAI API: For generating AI-powered reading content

These services may process and store your information according to their own privacy policies.

4. Content Generation with OpenAI

Some reading content available within Yomoyo may be generated using the OpenAI API.
While we strive to ensure content quality, we do not guarantee the accuracy or appropriateness of AI-generated material.

5. Sharing of Information

We do not sell, rent, or share your personal information with third parties except as necessary to operate the app and services described above. In the event of a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will take reasonable steps to ensure your information remains protected.

6. Links to Other Websites

Our app and services may contain links to external websites or services that are not operated by us. If you click on a third-party link, you will be directed to that third party's site.

We strongly advise you to review the Privacy Policy of every external site you visit.

We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party websites or services.

7. Your Rights and Choices

Account Deletion: You may delete your account and all associated data directly within the app under Profile Settings.
Note: Deleting your account does not automatically cancel any active subscriptions. You must manage subscriptions through your App Store account.

  • Access and Corrections: If you need assistance accessing, updating, or correcting your information, please contact us at support@yomoyo.ai.

8. Data Security

We implement industry-standard security measures, including secure communication (SSL/TLS) and strict access control using Firebase security rules.
However, no method of transmission over the internet, or method of electronic storage, is 100% secure. While we strive to use commercially acceptable means to protect your personal data, we cannot guarantee its absolute security.

Yomoyo is not intended for users under the age of 13.
If we become aware that a child under 13 has provided personal information, we will promptly delete it.

10. Changes to This Policy

We may update this Privacy Policy from time to time.
When we do, we will update the "Effective Date" at the top.
