Terms of Service

1. Description of Service

Plychess ("we", "our", "us") provides free chess tools—such as engine-powered analysis, puzzles, and online play. Some features may be available without an account, while others might require optional authentication.

2. Accounts & Authentication

• You are responsible for safeguarding your login credentials and all activity under your account.
• Provide accurate information and promptly update it when necessary.
• We may suspend or restrict access if we detect abuse or security risks.

3. Acceptable Use

• Do not disrupt, interfere with, or overload our infrastructure.
• Do not attempt to access areas or data you are not authorized to access.
• Do not scrape or harvest data in a way that burdens the Service.
• Do not upload malware, engage in spam, or use the Service for illegal purposes.

4. User Content

By uploading PGN files or other chess data ("Content"), you grant us a non-exclusive license to process, display, and store that Content solely to provide the Service. You confirm you have necessary rights and that your Content does not infringe third-party rights.

5. Privacy

Our Privacy Policy explains what data we collect, how we use it, and your choices. By using the Service, you acknowledge our privacy practices.

6. Service Providers

We rely on reputable third-party providers—such as hosting and analytics—to operate the Service (e.g., GA4 and Microsoft Clarity for analytics when enabled). Providers act under our instructions and may process data as described in the Privacy Policy.

7. Disclaimer of Warranties

The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied—including accuracy, reliability, or fitness for a particular purpose. Use analysis and insights at your own risk.

8. Limitation of Liability

To the fullest extent permitted by law, Plychess and its affiliates will not be liable for indirect, incidental, special, consequential, or punitive damages, or any loss of profits or data, arising from your use of—or inability to use—the Service.

9. Termination

We may suspend or terminate your access at any time if you breach these Terms or if required by law. Upon termination, sections related to Content, Warranties, Liability, and Changes survive as applicable.

10. Governing Law

These Terms are governed by the laws of the jurisdiction where Plychess operates, unless mandatory law provides otherwise. Any disputes will be heard in the competent courts of that jurisdiction.

11. Changes

We may update these Terms from time to time. Material changes will be announced on the website. Your continued use after an update means acceptance of the revised Terms.
