Content and code
Katalume retains rights in its problem statements, tests, curriculum, brand, and software. You retain ownership of original code you submit and grant us the limited rights needed to run, evaluate, store, and display it to you.
Accounts and availability
We may restrict or terminate access for material violations, security risk, fraud, or legal requirements. The service may change and may occasionally be unavailable. We do not promise that every result or learning resource is error-free.
Paid access
Paid memberships are also governed by the Billing terms and Refund policy. The checkout screen shows the price and cadence before you authorize payment.
Liability
To the extent permitted by applicable law, Katalume is provided without warranties and is not responsible for indirect or consequential loss. Nothing here excludes consumer rights or liability that cannot legally be excluded.
