Using the Services in violation of others’ rights;
Misusing or abusing reporting or complaint procedures (e.g., false reports);

We will inform you of this integration to facilitate, if needed, the transfer of your account, unless your organization has already notified you of such control. The organization’s administrator may then manage the account, access related Content, and possibly restrict or suspend your access.

Ownership: Unless otherwise stated, you retain full ownership of your Input Data and become the owner of Output Data generated by Naya for your use (as permitted by law). We assign you any rights we may have in such Output Data.

Similarity: Due to the nature of AI services, Output Data produced may not be unique, and other users may receive similar results. The assignment of rights only applies to Output Data unique to you, not to data produced for others or from Third-Party Services.

Moderation: OpenAI uses automated and human systems to detect content not compliant with its policies. OpenAI may thus limit access to certain features, restrict, suspend, or delete content or accounts in case of non-compliance. More info is available on their moderation page.

Opting out of training: You can choose not to have your data used by OpenAI to train its models by adjusting your OpenAI account settings, learn more here.

Accuracy: Artificial intelligence and machine learning evolve rapidly, and Output Data may sometimes be inaccurate, incomplete, or not faithfully reflect reality.

Never consider Output Data as your only reliable source or as a substitute for professional advice;
Always verify the accuracy and relevance of Output Data before sharing or using it;
Never use Output Data to make a legal or material decision about someone (employment, credit, housing, insurance, education, health…);
Calidius does not endorse Output Data: some answers may be incorrect, incomplete, or not reflect our viewpoint.
