Terms of Use

These Terms of Use govern the use of LusterPicture (the “App”). By installing or using the App, you agree to these terms.

1. Application of these terms

You may use the App only after agreeing to these terms. Installing or using the App constitutes your agreement.

2. Intellectual property

All intellectual property rights in the App and related programs, works, trademarks, and know-how belong to the developer. Copyright in images created or enhanced by a user remains with that user or the appropriate rights holder; the developer does not claim rights to those images.

3. Paid services and subscriptions

Some advanced features—including Strong Mode for Luster Boost, RAW-development brightness settings, and HEIF batch conversion beyond free limits—are offered as a paid subscription. Available features are described on the in-app purchase screen.

4. Prohibited conduct

You must not reverse engineer or decompile the App; infringe the intellectual property, reputation, or privacy of the developer or a third party; violate law or public order; or interfere with operation of the App.

5. Changes or suspension

The developer may change, suspend, or discontinue the App without prior notice and is not liable for damage resulting from such change or interruption.

6. Disclaimer

The App is provided “as is.” The developer does not guarantee that defects will be corrected or that features will remain available, and is not responsible for device damage, data loss, or other damage arising from use of the App.

7. Changes to these terms

The developer may revise these terms when necessary without prior notice.

8. Governing law and jurisdiction

These terms are governed by the laws of Japan. Any dispute relating to the App is subject to the exclusive jurisdiction of the court having jurisdiction over the developer’s location.
