Terms & Conditions

Welcome to UmamusumeAffinityCalculator.com (“we”, “us”, “our”). By accessing or using our Affinity (Compatibility) Calculator and related pages (the “Service”), you agree to these Terms & Conditions (“Terms”). If you do not agree, please do not use the Service.

1) What this service is

Umamusume Affinity Calculator is an unofficial fan utility that helps trainers estimate inheritance compatibility by letting you choose a Main Character, Legacy 1, Legacy 2, and (optionally) Grandparents, then showing a Total Affinity score and indicators like ○ / ◎. Results update as you change selections.

The calculator is based on simplified assumptions (e.g., static relationship points and trait-group matching) and is provided for informational / planning purposes only. It may not match the exact in-game mechanics in every situation.

2) No affiliation / trademarks

This site is a fan-made project and is not affiliated with, endorsed by, or sponsored by the owners of Uma Musume: Pretty Derby. All trademarks, character names, and related assets belong to their respective owners. You agree not to interpret the Service as official guidance.

3) Your responsibilities

• Use the Service lawfully and responsibly, and only for personal, non-abusive purposes.
• Verify decisions in-game—compatibility and inheritance outcomes can vary and are influenced by multiple factors.
• Do not attempt to disrupt the Service or its infrastructure (e.g., probing, scanning, scraping at scale, reverse engineering, or automated access that harms performance).

4) Intellectual property (site content)

The site’s original design, UI, copy, and code are protected by applicable copyright and related laws. You may not reproduce, redistribute, or commercially exploit substantial parts of the Service without permission, except as allowed by fair use or applicable law.

5) Availability & changes

We may modify, pause, or discontinue any part of the Service at any time (including calculation rules, UI, or supported content). We may also update these Terms from time to time. Continued use after changes means you accept the updated Terms.

6) Third-party services

The site may rely on third-party providers (e.g., hosting, security, analytics) and may link to third-party sites. We are not responsible for third-party content, policies, or practices.

7) No warranties

The Service is provided “as is” and “as available,” without warranties of any kind. We do not warrant that results will be accurate for your specific scenario, or that the Service will be uninterrupted or error-free.

8) Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages, or any loss of profits or data, arising from or related to your use of the Service.

9) Governing law

These Terms are governed by the laws of Pakistan, without regard to conflict of laws. Venue and jurisdiction will be in courts located in Pakistan, unless applicable consumer law requires otherwise.
