Terms of use

1. Acceptance

Using Kaneme, published by YIRIWA, LLC, means accepting these terms. They apply to the web application, REST API, and MCP server.

Kaneme is independent from other services published by YIRIWA, LLC. Using Kaneme does not create an account or marketing consent for those services.

2. Account and security

Access to the service requires a personal account. The customer is responsible for keeping their access methods confidential and for actions performed from their account.

API keys are personal. They are displayed only once when created, stored in hashed form, and may be revoked at any time. Any use made with a valid key is deemed to originate from its holder; a compromised key must be revoked immediately.

The account is intended for individual use. Sharing one account among several people or reselling it is not permitted. To work together, the Business offer brings separate accounts into an organization: each person keeps their own account, and the owner and administrators can see each member’s consumption of the shared balance.

3. Customer content and ownership

The customer retains full ownership of the texts submitted to the service, the voice derived from them, and content produced with the help of the service.

Text written by Kaneme is produced by third-party artificial intelligence models: those of Anthropic (Claude) and, as a fallback, those of OpenAI. These models apply an invisible, machine-readable marking that identifies the content as generated by artificial intelligence, as provided by Article 50 of Regulation (EU) 2024/1689 on artificial intelligence. Kaneme does not attempt to remove this marking and offers no way to do so; substantial rewriting of the text may nevertheless weaken it.

The customer grants YIRIWA, LLC a license strictly limited to the technical operation of the service: hosting their content, calculating and retaining their voice, and carrying out the operations they request. This license ends when the relevant content is deleted.

Customer texts are not shared with other customers or used to train a model made available to third parties. Two contributions, which the customer sets from their voice and can turn off at any time, are the exception: pooling style patterns under a pseudonym, never the text, for a voice linked to a regional register of French (on by default, can be turned off); and, only with the customer’s agreement, using their reference texts to improve the accuracy of voice fidelity measurement. The privacy policy sets out the legal bases.

The measurement engine is never recalibrated on text produced by artificial intelligence: this rule prevents the measurement from progressively validating its own output.

The customer warrants that they hold the rights to the texts they submit. When they build, measure, or use a third party’s voice, they also warrant that they have that person’s consent or authorization. Using the service to impersonate another person’s writing identity is prohibited.

A brand voice, created in a Business organization, belongs to the organization: when the person who built it leaves the organization, the voice stays and passes to its owner. A member’s personal voices leave with them.

The holder of a voice may grant another person a visa to measure with that voice or to write with it. The holder may withdraw it at any time and can consult the log of actions taken under the visa—date, type, result, never the text. The voice certificate remains reserved for the holder.

4. What the measurement says—and what it does not say

Kaneme produces scores and probabilities calibrated on a reference corpus. These results are statistical indicators, not proof.

The service abstains from returning a verdict when the conditions for a reliable measurement are not met. An abstention is not a service failure: it expressly indicates that no reliable conclusion can be made.

• Kaneme is not a general-purpose artificial-intelligence detector and does not claim to identify which model produced a text.
• Kaneme does not make text “undetectable” and must not be presented as doing so.
• A Kaneme result may not, by itself, support an accusation, disciplinary sanction, dismissal, or judicial decision.
• The free reading calculated without reference text counts markers of automated style; it never attributes authorship and returns no score. The stamp, available in the account journey and through API or MCP trial calls, requires reference texts and returns a calibrated probability—an indicator, never proof, within the limits stated above.

5. Prohibited uses

Prohibited uses include bypassing quotas or technical limitations, automating the creation of free accounts, attempting to extract or reconstruct service models or corpora, degrading service availability, or using the service to produce unlawful, defamatory, or misleading content about its author’s identity.

YIRIWA, LLC may apply rate limits and suspend access whose use threatens the security, availability, or integrity of the service.

6. Availability and changes

The service evolves. Features, models, and thresholds may be modified or replaced. When a change affects how a result is produced, the public documentation is updated accordingly.

Any material change to these terms will be brought to customers’ attention before it takes effect. Continued use after that date constitutes acceptance.

7. Termination and deletion

The customer may stop using the service and request deletion of their account at any time. Deletion results in the removal of their content and voice within the periods stated in the privacy policy. Deleting the account of a Business organization’s owner also deletes the organization and its shared balance: the owner should transfer it to a member, or dissolve it, before closing their account.

YIRIWA, LLC may terminate access for a serious breach of these terms under the conditions set out in the sales terms.

8. Governing law

These terms are governed by the laws of the State of Delaware, United States, subject to any more protective mandatory provisions in the consumer customer’s country of residence.
