03Intellectual property and data

Your Content (Created by You): You maintain full ownership over all content of your authorship, including: files you upload to the platform, documents you create or edit in our tools (wikis, presentations, notes, boards), texts you write, and any other content where you are the primary author, regardless of having received formatting or editing suggestions from the AI. You grant us only a limited, revocable, non-exclusive, and non-transferable license, for use strictly necessary for the provision and improvement of the Services, without commercial sub-licensing.

AI-Generated Content (Output): For content created directly by our artificial intelligence models through prompts and commands, you receive exclusive use rights and unrestricted commercial rights over your specific Output, being able to use it freely for any lawful purpose. You recognize that other users may receive similar outputs through their own distinct inputs, but each specific Output belongs exclusively to the user who generated it.

Restriction of Use for Model Training: Despite the rights granted over the Output, it is expressly forbidden to use the Outputs generated by Nama's Services, in an isolated or aggregated way, to train, adjust, supervise, validate, calibrate, or compare artificial intelligence models or similar systems of third parties, public or private, with or without commercial purposes. This restriction applies even if the Outputs have been obtained in a legitimate way, aiming to preserve the technological, intellectual, and competitive integrity of the models developed by Nama.

Monitoring and Suspension for Massive Generation of Outputs: Nama reserves the right to monitor and audit usage patterns that may characterize automated or systematic behavior focused on the massive generation of Outputs for purposes of reverse engineering, technological replication, or training of competing models, being able to restrict or suspend access at any time, including by applicable legal measures.

Ownership of Generated Contents: You acknowledge that exclusivity over the generated Output applies only to the specific result of your interaction with Nama's models, and that substantially similar Outputs may be generated for third parties without this configuring a violation of your rights.

Output as Expressive Manifestation Derived from Proprietary Technology: The generated Output is an expressive manifestation produced by Nama's proprietary model. Although the User holds rights over the specific result generated, the Output should not be interpreted as an autonomous work or separate from the underlying technology, whose ownership remains entirely with Nama. Any attempt to claim exclusivity over the functioning, language pattern, or behavior of the model will be considered a violation of intellectual property rights.

Important about Generative AI: Our AI may present limitations, inaccuracies, and inconsistencies inherent to the technology. We cannot guarantee absolute accuracy of the generated results. It is your responsibility to verify the suitability, legality, and originality of the use of the Output for your specific purposes. Nama does not assume responsibility for eventual violation of third-party rights contained in the Output, it being the user's responsibility for final verification before its commercial or public use.

Use of Data for Service Improvements: By default, we do not use your content for AI model training. We use only aggregated and anonymized data for operational improvements of the Services (performance, security, technical functionalities).

Voluntary Contribution Program: You may choose to contribute data for model improvements through account settings, receiving benefits such as credits or early access to functionalities. This contribution is always optional and revocable.

Feedback: Any feedback you provide grants us a perpetual and non-exclusive license for internal use in order to improve the Services. Feedback will be used in an aggregated and anonymized way and does not confer on you rights over the resulting improvements.

Your Responsibility over Processed Content: You, as the Data Controller, are the sole responsible for all Processed Content you submit to the Services. You represent and warrant that you possess all rights, authorizations, and necessary legal bases (including consent, where applicable) to collect, share, and instruct us to process such data. Nama acts strictly as an Operator, treating data under your instructions to provide the Services. We have no control over the Processed Content and we disclaim any responsibility related to its legality, accuracy, or suitability. Any damages caused to Nama by the treatment of illicit content or content that violates third-party rights will be of your full responsibility.

Consultancy and Customization Services: The rights and obligations provided for in these Terms apply exclusively to the standard use of the platform. Additional consultancy services, customized development, training, premium support, or model fine-tuning will require a specific contract, which will define scope, deliveries, payment, and intellectual property over eventual results. Special conditions, such as SLA, dedicated support, guaranteed availability, confidentiality clauses, or penalties, must also appear in a separate contract, which will prevail over these Terms in case of conflict.

Revocation of License over Output in Case of Violation: In case of violation of these Terms, especially the clauses relating to acceptable use, reverse engineering, or training of external models, the license granted over the Output may be revoked at Nama's exclusive discretion, without prejudice to applicable legal measures.

Copyright Protection: For notifications of alleged copyright violation, use the channel legal@nama.ai. The notification must contain: (i) clear identification of the protected work; (ii) identification of the infringing material; (iii) complete contact information; (iv) declaration of good faith about unauthorized use; (v) declaration under the penalties of the law on truthfulness of the information; (vi) physical or electronic signature of the holder or legal representative. After analysis, we may remove content, notify the responsible user, or terminate accounts of repeat infringers.

04Limitations of artificial intelligence

Functioning of AI Systems: Nama's AI systems are built based on language and machine learning models, operating under architectures such as RAG (Retrieval-Augmented Generation) and with API integrations with vector databases and indexed documents, aiming at: support for decision-making, semantic search, assisted text generation, and automation of flows based on natural language.
