Effective Date: August 27, 2026
Last Updated: August 27, 2026

This End User License Agreement ("EULA" or "Agreement") is a legal agreement between you ("User," "you," or "your") and Nekonomikon Co., Ltd., a company organized under the laws of Japan with its principal place of business in Tokyo, Japan ("Nekonomikon," "Company," "we," "our," or "us").

This Agreement governs your use of the mobile application "Hi, world" ("Hi," "App," or "Application"), including software and related functionality made available through the App.

By downloading, installing, accessing, or using the App, you agree to be bound by this Agreement. If you do not agree to this Agreement, you must not download, install, access, or use the App.

This EULA should be read together with our Terms of Use and Privacy Policy, which contain additional terms governing your use of the Service and our processing of information.

1. License Grant

Subject to your compliance with this Agreement, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, and revocable license to download, install, and use the App on an iOS device that you own or control.

The license is granted solely for your personal use of the Service and does not transfer ownership of the App or any Company intellectual property to you.

Your use of the App is also subject to the applicable terms and conditions of the Apple App Store and your agreement with Apple.

2. License Restrictions

Except where expressly permitted by applicable law, you may not:

copy, reproduce, modify, adapt, translate, or create derivative works based on the App;
reverse engineer, decompile, disassemble, or attempt to derive the source code of the App;
distribute, sublicense, lease, rent, sell, or otherwise transfer the App or your rights under this Agreement;
use the App to provide services to third parties or operate the App for commercial purposes without our prior written permission;
remove, alter, or obscure copyright, trademark, or other proprietary notices;
circumvent, disable, or interfere with security features or access controls of the App;
use the App to infringe intellectual property, privacy, publicity, or other rights of any person;
use automated means to access, scrape, copy, collect, or harvest information from the App without our prior written permission;
interfere with, disrupt, or place an unreasonable burden on the App or its infrastructure;
use the App in violation of applicable laws or regulations.

3. Eligibility and Accounts

3.1 Age Requirement

You must be at least 16 years old to create an account and use the App.

By downloading, installing, or using the App, you represent that you meet this age requirement or otherwise satisfy the minimum age requirements applicable to you under applicable law.

3.2 Account Registration

To use the App, you must register using an email address.

We send a verification code to the email address you provide for registration and sign-in. The App does not require a password for account access.

After registration, we assign your account a unique account ID. You may choose a nickname or display name for use within the App.

You are responsible for providing accurate information and for maintaining access to the email address associated with your account.

3.3 Loss of Email Access

Your account is directly associated with the email address used for registration.

If you lose access to that email address, we may not be able to verify your ownership of the account. As a result, we may be unable to recover your account or restore access to content associated with it.

You are responsible for maintaining access to your registered email address.

4. User Content

The App allows you to create, upload, organize, and share content through Flips and related features ("User Content").

User Content may include text, photographs, videos, audio, links, and other materials supported by the App.

You retain ownership of your User Content.

You are responsible for the User Content you create, upload, or share and represent that you have all rights, permissions, and legal authority necessary to use and share that content.

Your User Content must comply with this Agreement, our Terms of Use, and applicable law.

5. Flip Visibility

5.1 Private Flips

A Private Flip is visible only to you, the creator of the Flip.

5.2 Public Flips

A Public Flip is visible to all users of the App.

You should carefully consider the information contained in a Flip before making it Public.

5.3 Changing Visibility

You may change a Private Flip to Public.

Once a Flip has been made Public, you cannot change it back to Private.

Making a Flip Public is therefore an irreversible action with respect to its visibility setting.

5.4 Forwarded Public Flips

Public Flips may be forwarded, collected, or otherwise reused by other users through functionality provided by the App.

If another user forwards or reuses a Public Flip, the forwarded or reused content may remain available within that user's collection or content even if you subsequently delete the original Flip.

You acknowledge that once a Public Flip has been forwarded or reused by another user, you may no longer have control over copies or versions of that content created through such functionality.

6. License to User Content

You retain ownership of your User Content.

By submitting User Content to the App, you grant Nekonomikon a limited, non-exclusive, worldwide, royalty-free license to host, store, reproduce, process, display, and transmit that User Content solely to the extent reasonably necessary to:

provide and operate the App;
store and display your User Content;
make Public Flips available to users of the App in accordance with their visibility settings;
enable users to forward or reuse Public Flips through available functionality;
maintain, secure, troubleshoot, and improve the App;
comply with applicable law or protect the rights and security of users and the App.

This license does not transfer ownership of your User Content to Nekonomikon.

We do not obtain ownership of your User Content by virtue of this Agreement.

The license for User Content ends when that content is deleted from our active systems, subject to temporary retention in backups, legal or security retention, and copies or versions of Public Flips that other users have previously forwarded or reused.

7. Privacy

Your use of the App is also governed by our Privacy Policy, which explains how we collect, use, store, and disclose information.

Our Privacy Policy is incorporated into this Agreement by reference.

You can review the Privacy Policy through the App or at: Hi Privacy Policy

The App currently requests access to certain device permissions, including camera and location permissions.

If you grant location permission, the App may use your location to provide weather information. We do not store your precise location as part of your account.

For further information about permissions, analytics, AWS, and other data processing, please refer to the Privacy Policy.

8. Intellectual Property

The App and all materials provided by Nekonomikon in connection with the App, including software, source code, design, interfaces, graphics, logos, trademarks, sounds, artwork, and other Company Content, are owned by or licensed to Nekonomikon and are protected by applicable intellectual property laws.

Except for the limited license expressly granted under this Agreement, no rights or licenses to the App or Company Content are granted to you.

You may not use our trademarks, logos, names, or other branding without our prior written permission.

9. Updates and Changes to the App

We may provide updates, upgrades, bug fixes, security patches, and other modifications to the App.

Some updates may be necessary for continued use of the App.

We may also add, modify, suspend, or discontinue features of the App from time to time.

Where required by applicable law, we will provide notice of material changes or discontinuation.

10. Suspension and Termination

This Agreement remains effective until terminated by you or us.

We may suspend or terminate your license to use the App or restrict access to the App if:

you materially or repeatedly violate this Agreement or our Terms of Use;
you violate applicable law;
your use of the App creates a security, safety, or legal risk;
you engage in fraudulent, abusive, or harmful conduct;
we are required to do so by law.

You may terminate this Agreement by stopping your use of the App and, where applicable, deleting your account.

Upon termination, your license to use the App will end.

Termination does not affect provisions that by their nature should survive termination, including provisions concerning intellectual property, User Content, disclaimers, limitations of liability, governing law, and dispute resolution.

Termination of this EULA does not necessarily result in the immediate deletion of all information or User Content. Account and content deletion is governed by the Terms of Use and Privacy Policy.

Nothing in this section limits any rights you may have under mandatory applicable law.

11. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS.

WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES ARISING OUT OF OR RELATING TO YOUR USE OF OR INABILITY TO USE THE APP.

SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS OF LIABILITY. WHERE SUCH LIMITATIONS ARE NOT PERMITTED, OUR LIABILITY WILL BE LIMITED TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW.

13. Apple App Store Terms

This Agreement is between you and Nekonomikon Co., Ltd., and not with Apple.

Nekonomikon, not Apple, is solely responsible for the App, its content, and addressing any claims by you or any third party relating to the App or your possession and/or use of the App, including: (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; (iii) claims arising under consumer protection, privacy, or similar legislation; and (iv) the investigation, defense, settlement, and discharge of any third-party claim that the App or your use of it infringes that third party's intellectual property rights.

Apple has no obligation to provide maintenance or support services for the App.

In the event of any failure of the App to conform to an applicable warranty that cannot legally be excluded, you may notify Apple, and Apple may refund any applicable purchase price in accordance with its policies. To the maximum extent permitted by applicable law, Apple will have no further warranty obligations with respect to the App.

Apple and its subsidiaries are third-party beneficiaries of this Agreement and may enforce this Agreement against you as third-party beneficiaries.

Your use of the App must also comply with applicable Apple App Store terms and conditions.

14. International Use and Export Controls

The App may be made available to users in different countries.

You are responsible for complying with applicable laws and regulations in the jurisdiction from which you access or use the App.

15. Governing Law and Disputes

If you are a consumer, you may have mandatory rights under the laws of your country or place of residence. Nothing in this Agreement is intended to deprive you of those rights.

Except where mandatory consumer protection law provides otherwise, this Agreement is governed by the laws of Japan, without regard to conflict-of-law principles.

To the extent permitted by applicable law, disputes arising out of or relating to this Agreement or the App will be subject to the jurisdiction of the Tokyo District Court as the court of first instance.

16. Changes to This Agreement

We may update this Agreement from time to time to reflect changes to the App, our business practices, legal requirements, or other operational considerations.

When we make material changes, we will provide notice as required by applicable law and, where appropriate, give you an opportunity to review the updated Agreement before it takes effect.

The updated Agreement will include a revised "Last Updated" date.
