3. User Content

You may enter quotes, notes, and other text into the App. This content is stored only on your device and is never transmitted to the developer.

The App is provided “as is” without warranties of any kind, express or implied. The developer does not warrant that:

The developer is also not responsible for any issues arising from third-party services used within the App (such as Google AdMob or Firebase Analytics).

6. Changes to the App and Terms

The developer may update the App’s features, design, or functionality at any time without notice. The developer may also update these Terms at any time. The updated Terms will take effect when published on this page. Continued use of the App after changes constitutes your acceptance of the updated Terms.

These Terms are governed by and construed in accordance with the laws of Japan. Any disputes arising under these Terms shall be subject to the exclusive jurisdiction of the courts in the developer’s jurisdiction.
