Last Updated: June 11, 2026

These Terms of Service ("Terms") govern your use of Agari ("the Game"), developed and published by Ryan Sullenberger ("we," "us," or "our"). By downloading, installing, or using the Game, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the Game.

1. Eligibility

You must be at least 13 years of age (or such higher minimum age as required by law in your jurisdiction) to use the Game. If you are between that minimum age and 18 years of age (or the age of majority in your jurisdiction), you may only use the Game with the consent of a parent or legal guardian who agrees to be bound by these Terms on your behalf.

The Game does not involve real-money gambling. All point values and scores within the Game are fictional and have no monetary value.

2. License Grant

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the Game for your personal, non-commercial use on devices you own or control, through authorized distribution platforms (Steam, Apple App Store, Google Play, or our official website).

Content Creation. Personal use includes streaming, recording, and sharing gameplay videos and screenshots on social media and video platforms (such as Twitch, YouTube, or similar), provided such content does not falsely imply official affiliation with, sponsorship by, or endorsement from us. You may monetize such content (for example, through platform partner programs or viewer support) so long as the content itself remains original gameplay or commentary and does not redistribute the Game's code, assets, or proprietary materials apart from the gameplay being shown.

You may not:

3. Online Services

The Game includes optional online multiplayer functionality. To facilitate peer-to-peer connections between players, we operate a signaling server ("Online Services"). The signaling server assists with initial connection setup only — game data is transmitted directly between players via peer-to-peer connections, not through our servers.

Availability. We provide the Online Services on an "as available" basis. We may modify, suspend, or discontinue the Online Services at any time, with or without notice, and without liability to you. We do not guarantee that the Online Services will be available at all times or in all regions.

Conduct. When using the Online Services, you agree not to:

We reserve the right to restrict access to the Online Services for any user who violates these Terms.

4. User Data and Privacy

What We Collect. The Game stores your preferences (such as display name, audio settings, riichi BGM choice, match configuration), a randomly-generated installation ID (used for online-multiplayer rejoin recognition and as a short suffix on your Daily Wall display handle to disambiguate identical player names), optional match logs and statistics (only if you enable game logging in Settings), and Daily Wall result history locally on your device. This data is not transmitted to us or any third party, except as described below.

Online Multiplayer. When you use the online multiplayer feature, your display name, installation ID, voice and riichi BGM choices, and gameplay actions are shared with other players in your session via peer-to-peer connections. This data is not stored on our servers. The signaling server processes connection metadata (such as IP addresses) only as necessary to establish peer-to-peer connections; this data is not logged or retained. If future game features broadcast additional preferences over peer-to-peer connections, the Privacy Policy will be updated to reflect them.

User-Initiated Sharing. Some Game features (such as the Daily Wall mode's "Copy Result" action) include a handle of the form "DisplayName#short-installation-id" in the data they place on your clipboard. This data leaves your device only when you take an explicit action; we do not collect or store it.

Game Logs. The Game may optionally save match logs to your local device. These logs remain on your device and are not transmitted to us or any third party.

Gameplay Data. We do not currently collect any gameplay data beyond what is stored locally on your device. We reserve the right to collect anonymized gameplay data in the future (such as match logs, game statistics, tile sequences, AI interactions, and in-game decisions) solely for the purposes of improving the Game, training AI models, analyzing game balance, and fixing bugs. If we begin collecting such data in the future, we will provide an opt-out in the Game's settings and update our Privacy Policy accordingly. Gameplay data, if collected, would not include personal information — it would not be linked to your identity, device, or account.

Analytics and Tracking. We do not use cookies, advertising identifiers, or behavioral tracking technologies. We do not track your activity outside of the Game. Any data collection is limited to anonymized gameplay data as described above.

Children's Privacy. We do not knowingly collect personal information from children under the age of 13. If you are a parent or guardian and believe your child has provided personal information to us, please contact us at the address below, and we will take steps to delete such information.

WITHOUT LIMITING THE FOREGOING, WE SHALL NOT BE LIABLE FOR ANY DAMAGE TO YOUR DEVICE, COMPUTER HARDWARE, OPERATING SYSTEM, SOFTWARE CONFIGURATION, OR DATA RESULTING FROM YOUR DOWNLOAD, INSTALLATION, OR USE OF THE GAME.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE GAME SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE GAME IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES. IN SUCH JURISDICTIONS, OUR LIABILITY SHALL BE LIMITED TO THE GREATEST EXTENT PERMITTED BY LAW.

8. Indemnification

You agree to indemnify, defend, and hold harmless Ryan Sullenberger and our affiliates, licensors, and service providers from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of or inability to use the Game; (b) your violation of these Terms; or (c) your violation of any rights of any third party.

9. Third-Party Platforms

The Game may be distributed through third-party platforms, including but not limited to Steam (Valve Corporation), the Apple App Store (Apple Inc.), and Google Play (Google LLC). Your use of these platforms is subject to their respective terms of service and privacy policies. We are not responsible for the practices or policies of these third-party platforms.

If you purchased the Game through a third-party platform, any refund requests must be directed to that platform in accordance with its refund policies.

10. Modifications to the Game and Terms

We reserve the right to modify, update, or discontinue the Game at any time without notice or liability. We may update these Terms from time to time. If we make material changes, we will update the "Last Updated" date at the top of these Terms and, where practicable, provide notice through the Game or our website (agari.app). Your continued use of the Game after any changes to these Terms constitutes your acceptance of the revised Terms.

11. Termination

We may suspend or terminate your access to the Game or Online Services at any time, for any reason, without notice or liability. Upon termination, your license to use the Game is immediately revoked.

Sections 5 through 8 and any other provisions that by their nature should survive termination shall survive any termination of these Terms.

12. Governing Law and Dispute Resolution

These Terms shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, United States, without regard to its conflict of laws principles.

Any dispute arising out of or relating to these Terms or the Game shall be resolved through binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, except that either party may seek injunctive or equitable relief in any court of competent jurisdiction for disputes involving intellectual property.

Class Action Waiver. To the maximum extent permitted by applicable law, you agree that any dispute resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action. If this class action waiver is found to be unenforceable, then the entirety of this arbitration provision shall be null and void.

Small Claims Exception. Notwithstanding the above, either party may bring an individual action in small claims court for disputes within its jurisdictional limits.

13. General Provisions

Entire Agreement. These Terms constitute the entire agreement between you and us regarding the Game and supersede all prior agreements and understandings.

Severability. If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.

Waiver. Our failure to enforce any right or provision of these Terms shall not be deemed a waiver of such right or provision.

Assignment. You may not assign or transfer these Terms or your rights hereunder without our prior written consent. We may assign these Terms without restriction.
