Terms of Use

Chromono (the "App") / Operator: GIMPEI OKADA
Last updated: July 24, 2026

The Service

The App provides an editing tool that converts photos and videos to grayscale while keeping a specific color range.

Pricing and Purchases

The App is free to use (ads are displayed). Purchasing the one-time paid features removes ads and unlocks video features. Purchases are made through Apple's In-App Purchase and are subject to Apple's terms. Because it is a one-time (non-consumable) purchase, you can restore it after switching or reinstalling on a device that uses the same Apple ID.

Intellectual Property and Your Works

The rights to the works (images and videos) you create with the App belong to you. This assumes you hold the necessary rights to the source material you edit.

We ask that you use works created with the App for personal, non-commercial purposes. If you wish to use them commercially, please consult the operator (chromono.app@gmail.com) in advance.

The intellectual property contained in the App — including logos, watermarks, sample assets, and UI design — belongs to the operator. Unauthorized reproduction, commercial use, or redistribution of these is prohibited.

Prohibited Conduct

Please refrain from uses that violate laws, infringe the rights of third parties, or interfere with the provision of the App.

Disclaimer

The App is provided "as is." To the extent permitted by law, we make no warranty as to the completeness of processing results, saving, or exporting. Saving or exporting may fail due to reasons such as insufficient free space on your device.

Changes to These Terms

These terms may be changed as needed. If you continue to use the App after a change, you are deemed to have agreed to the change.
