Terms of Service

Last updated: September 4, 2026

1. Acceptance of Terms

By accessing or using Rivory (“the Service”), a product of Kleos Labs LLC, you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Service.

2. Description of Service

Rivory is a free social sports-prediction app. Users make picks and bracket predictions across competitions including the NFL, the UEFA Champions League, the US Open, and the FIFA World Cup, join groups and clubhouses, chat with other members, and compete on leaderboards. Rivory is not gambling — it does not involve real-money wagering, and no cash prizes are offered.

Trademark Disclaimer

Rivory is not affiliated with, endorsed by, or in any way officially connected with the NFL, UEFA, the United States Tennis Association (organizer of the US Open), FIFA, or any of their subsidiaries or affiliates. Team names, league names, tournament names, and associated logos referenced in the Service are trademarks of their respective owners, used only to identify the real-world competitions the Service lets users predict. All other trademarks, service marks, trade names, and logos are the property of their respective owners.

3. User Accounts

• You must provide accurate information when creating an account
• You are responsible for maintaining the security of your account
• You must be at least 13 years old to use this Service
• One person may not maintain multiple accounts

4. User Conduct

You agree not to:

• Use the Service for any illegal purpose
• Attempt to gain unauthorized access to other accounts or systems
• Use automated tools to access the Service without permission
• Harass, abuse, or harm other users, including in group chat
• Create offensive or inappropriate display names, handles, group names, or clubhouse names

5. Predictions and Scoring

• Each game shows its entry window and ranking rules. Personal picks may remain available after a deadline in supported modes; late personal picks do not automatically qualify for ranked groups or boards
• Scores are calculated automatically based on official results
• The scoring system for each competition is described within that competition
• This is a game for entertainment purposes only — it is not gambling, involves no real-money wagering, and no cash prizes are guaranteed

6. Rivory Plus Subscriptions

Rivory offers free features and optional Rivory Plus subscriptions. The price, billing period, included features and any eligible trial are shown before you purchase. Payments are billed through your Apple App Store or Google Play account.

Subscriptions renew automatically unless cancelled before renewal through the store where you subscribed. A free trial, when offered and available to your store account, converts to the displayed paid subscription unless cancelled before the trial ends. Manage or cancel your subscription in that store’s subscription settings. Refund requests are handled through the applicable store.

Deleting your Rivory account or uninstalling the app does not cancel your subscription. You can request account deletion without first cancelling, but store billing continues until you cancel the subscription.

7. Intellectual Property

The Service and its original content, features, and functionality are owned by Kleos Labs LLC. The NFL, UEFA Champions League, US Open, and FIFA World Cup are trademarks of their respective owners. This Service is not affiliated with or endorsed by the NFL, UEFA, the USTA, FIFA, or any other league or organization referenced in the app.

8. Limitation of Liability

The Service is provided “as is” without warranties of any kind. We are not liable for any indirect, incidental, or consequential damages arising from your use of the Service. We do not guarantee the accuracy of match results, schedules, or score calculations.

9. Indemnification

You agree to indemnify and hold harmless Kleos Labs LLC from any claims, damages, losses, or expenses (including reasonable legal fees) arising out of your use of the Service or violation of these Terms.

10. Termination

We may terminate or suspend your account at any time for violations of these terms. You may delete your account at any time through Profile.

11. Force Majeure

We are not liable for any failure or delay in performing our obligations where such failure or delay results from events beyond our reasonable control, including but not limited to natural disasters, acts of government, internet outages, or the cancellation, postponement, or rescheduling of any competition or sporting event referenced in the Service.

12. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Nebraska, United States, without regard to its conflict of law provisions.

13. Dispute Resolution

Any dispute arising from these Terms or your use of the Service shall first be resolved through good-faith informal negotiation by contacting us at support@kleoslabs.dev. If the dispute cannot be resolved informally within 30 days, either party may pursue resolution in the state or federal courts located in the State of Nebraska.

14. 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 so that these Terms shall otherwise remain in full force and effect.

15. Entire Agreement

These Terms, together with our Privacy Policy, constitute the entire agreement between you and Kleos Labs LLC regarding the use of the Service.

16. Changes to Terms

We reserve the right to modify these terms at any time. Continued use of the Service after changes constitutes acceptance of the new terms.
