  • Automated submissions (bots, scripts, etc.) are strictly prohibited unless explicitly authorized by the administrators
  • Submission results, execution details, and verdicts are provided on an "as-is" basis; while we strive for accuracy, we do not guarantee error-free evaluation

GreenOJ hosts both public and private programming contests. By participating in any contest, you agree to:

  • Abide by all contest-specific rules, including time limits, permitted languages, and scoring criteria

  • Not share contest problems, test cases, or solutions with others during or before the contest ends
  • Accept the decisions of the contest administrators regarding results, penalties, and disqualifications as final

Any form of cheating, plagiarism, or manipulation of the contest system may result in disqualification, account suspension, and/or a permanent ban from the Platform.

  • Using the Platform for any unlawful purpose or in violation of any applicable laws or regulations
  • Posting offensive, abusive, defamatory, or otherwise inappropriate content in clarifications, profiles, or any user-generated content area

6. Intellectual Property

All content on GreenOJ, including but not limited to problem statements, editorials, test cases, UI design, logos, and branding, is the intellectual property of GreenOJ and GUBCPC unless otherwise credited. You may not:

7. Rankings, Ratings & Leaderboards

GreenOJ maintains contest ratings, solve-count rankings, and leaderboards. By using the Platform, you acknowledge that:

The Platform may contain links to third-party websites or services (e.g., Google AdSense, sponsor websites). We are not responsible for the content, privacy policies, or practices of any third-party sites or services.
