  1. The Service uses artificial intelligence models (in particular Anthropic Claude) to evaluate essays, generate explanations, adapt task difficulty, and provide other educational features.
  2. The User acknowledges and accepts that:
    • results generated by AI are auxiliary, educational, and indicative, and do not constitute official exam grading;
    • AI may generate incomplete, imprecise, or in exceptional cases incorrect answers (so-called hallucinations) — the User should verify received information in source materials;
    • AI evaluations do not replace teacher or examiner assessments, nor the result of the matura exam organized by CKE (Central Examination Board);
    • AI evaluation criteria are based on published CKE criteria and educational guidelines but may differ from a human examiner's assessment;
    • the Service does not guarantee achieving a specific matura or other exam result;
    • the Provider is not liable for educational or life decisions made solely based on AI-generated results.
  3. AI evaluations do not constitute decisions within the meaning of Art. 22 GDPR — they do not produce legal effects or significantly affect the User's legal situation. The User has the right to contest an AI evaluation and obtain an explanation of its basis.
  4. It is prohibited to use the AI provided in the Service for purposes inconsistent with its intended use, including generating offensive, illegal content, content infringing copyright, or intended to unethically circumvent CKE criteria.

§ 11. User obligations

  1. The User is obliged to use the Service in accordance with the Terms, applicable law, good practices, and principles of social coexistence.

    • circumventing free access limits (including creating multiple accounts),
    • sharing the account with third parties or reselling access,
    • automated downloading of the Service's educational content for commercial purposes,
    • using the Service's content to train AI models without the Provider's consent,
    • misleading the Provider (e.g. false complaints, chargebacks).
  3. Violation of the above may result in Account suspension in accordance with § 15.

  2. The User receives a non-exclusive, non-transferable license to use the Service's content solely for their own learning purposes, during the term of the contract.
  3. Copying, distributing, publishing, modifying, or sharing the Service's content with third parties without the Provider's written consent is prohibited.

    • AI-generated content in terms of its factual accuracy in exceptional cases (AI hallucinations),
    • data loss resulting from the User's actions (e.g. deleting the Account).
  3. The Provider's liability towards a User who is not a Consumer for non-performance or improper performance of the contract is limited to the amount paid by the User in the last 12 months. This limitation does not apply to liability for damages caused intentionally.
  4. This section does not limit the Provider's liability towards a Consumer to the extent such limitation would conflict with mandatory legal provisions.

  3. The Provider will consider the complaint within 14 days of receipt. Failure to respond within 14 days means the complaint is considered justified (in the case of Consumers).
  4. In case of non-conformity of digital content with the contract, the Consumer has the rights under Chapter 5b of the Consumer Rights Act, including the right to demand that the digital content be brought into conformity with the contract or the price be reduced, and in certain cases — to withdraw from the contract.

  3. Before suspending the Account (in non-gross cases), the Provider will call on the User to cease the violations with a deadline of no less than 3 days.
  4. Account suspension for reasons attributable to the User does not entitle to a refund for the current billing period or for unused credits.

§ 17. Changes to the Terms

  1. The Provider may amend the Terms for important reasons, such as: changes in law, introduction of new Service features, changes in the manner of providing services, security considerations.
