Terms of service

Last updated: October 2026

1. The service

BrokenCluster provides practice problems, temporary sandbox machines, automatic grading, solutions and related features. Problems are original. BrokenCluster is not affiliated with, endorsed by or a substitute for any certification body or technology vendor.

2. Your account

Keep your sign-in details secure. One person per account. You must be old enough to form a binding contract in your country, or have a guardian's permission.

3. Acceptable use of sandboxes

  • Use lab machines only to work on BrokenCluster problems.
  • Do not try to escape the sandbox, attack other systems, mine cryptocurrency, run denial-of-service tools or store illegal content.
  • Do not try to manipulate graders, points or leaderboards (for example with multiple accounts or automated solving).

We may stop sessions, remove XP, contest results or certificates, or suspend accounts that break these rules.

4. Content

Problems, solutions and explanations belong to BrokenCluster. You may use them to learn and may share links, but may not copy the problem bank or republish solutions in bulk.

5. Pro subscriptions

Pro renews automatically each month or year until you cancel. Cancel any time in Settings; you keep Pro until the end of the paid period. Prices may change with at least 30 days' notice before your next renewal. Refunds are covered by our refund policy.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

6. Certificates

When level exams launch, BrokenCluster certificates will state what was assessed. They are BrokenCluster credentials, not accredited or vendor certifications. We may revoke certificates obtained by cheating.

7. Availability and liability

We work hard to keep BrokenCluster available, but provide it “as is”. To the extent allowed by law, our liability is limited to the amount you paid us in the 12 months before a claim.

8. Changes

We will tell you about important changes to these terms by email or in the product before they take effect.
