Basis Data License — Free for Commercial Use, No Resale/Redistribution Version 1.0 Dataset: Basis Conversations 1500 Publisher: Luvu, Inc., a Delaware corporation operating as Basis Official repository: https://huggingface.co/datasets/basis-ai/basis-conversations-1500 Contact: data@withbasis.co Custom licenses are available on request: data@withbasis.co. 1. PARTIES, ACCEPTANCE AND SCOPE This agreement is between Luvu, Inc., operating as Basis ("Basis"), and the individual or legal entity identified in the access request ("Recipient"). An individual accepting for an organization represents that they have authority to bind that organization. An individual accepting personally must be legally able to enter this agreement. Recipient accepts this version by affirmatively accepting it through the official repository's access-request process or another process authorized by Basis. The license takes effect when that acceptance is complete and Basis grants access to the Dataset through that process. A preview request or receipt of proposed terms for review alone does not create a license. Basis may decline an access request. "Dataset" means the Basis Conversations 1500 release that Basis makes available to Recipient under this agreement: its recordings (one track per speaker), transcripts, annotations, speaker and conversation metadata, manifests, and accompanying documentation. Its repository revision or release identifier identifies the delivered version. The license covers only material that Basis supplies under these terms; separately licensed material and separately contracted deliveries remain subject to their own terms. "Source Materials" means the Dataset and copies, extracts, subsets, combinations or transformations that contain its substantive content. This includes clipped, denoised, re-encoded or otherwise transformed recordings; transcripts and their translations; and source-containing annotations, features, embeddings or other representations. Independent facts, commonplace words and phrases, and independently created material do not become Source Materials merely because they also occur in the Dataset. Sections 3 and 4 distinguish Source Materials from permitted models and results. "Model" includes machine-learning models, weights, adapters and other learned parameters trained or improved using the Dataset. "Results" includes Model outputs, aggregate statistics and research findings. "Personnel" means Recipient's employees and contractors, including cloud, compute, annotation and training providers, acting solely on Recipient's behalf. 2. LICENSE TO USE THE DATA Subject to this agreement, Basis grants Recipient a worldwide, nonexclusive, royalty-free license, without a license fee, to download, copy, store, process, annotate, modify and combine the Dataset for research and commercial purposes. This includes pretraining, training, fine-tuning, distillation, evaluation, benchmarking, testing and improvement of Models, and development and operation of commercial products and services. The grant includes copyright, sound-recording, performance and database rights to the extent Basis controls those rights and they are needed for these permitted uses. The license for a delivered release is perpetual, subject to Section 9. It is nontransferable except under Section 11 and does not permit sublicensing the Dataset. Basis retains its rights in the Dataset. Recipient receives no promise of further deliveries, updates, support, continued hosting or exclusivity. 3. MODELS, OUTPUTS AND COMMERCIAL PRODUCTS Recipient may use, publish, distribute, license and sell compliant Models and Results, and operate commercial applications, hosted inference services and APIs using them, without royalties, revenue sharing or further permission from Basis. General speech recognition, speech synthesis, conversational modeling, turn-taking, diarization and source-separation development are permitted, subject to the privacy and voice-identity restrictions in Section 6. Basis claims no ownership of Recipient's Models, software, original annotations or Results merely because Recipient used the Dataset. Recipient need not publish its source code, model weights or training methods. Recipients of compliant Models and Results need not obtain a Dataset license merely to use those artifacts. No obligation to license Models or Results under these same terms is imposed. These permissions do not confer rights in Source Materials included in an artifact. A Model or Result is not Source Materials merely because it was learned or generated from the Dataset. Section 4 continues to govern redistribution of the Dataset and copies or excerpts of it. 4. NO RESALE OR REDISTRIBUTION OF SOURCE MATERIALS Except for the limited access in Section 5 and the illustrative excerpts permitted below, Recipient must not sell, resell, rent, sublicense, publish, mirror, upload, lend, share or otherwise provide Source Materials to any other person or entity, whether for payment or free of charge. This prohibition covers the complete Dataset and any portion of it, including through data marketplaces, public or shared repositories, downloadable archives, bundled training-data products, brokerage, retrieval APIs or services that supply access to Source Materials. Reformatting, filtering, translating, adding labels, combining with other data, or making another source-preserving transformation does not remove this restriction. Other prospective users must obtain their own authorized access directly from Basis, including through Basis's official Hugging Face repository. Selling a compliant Model, application, inference API or service under Section 3 is permitted and is not resale of the Dataset. Sharing aggregate findings and links to Basis's official repository or authorized public samples is permitted. Recipient may include short excerpts in papers, presentations, blog posts and model documentation to illustrate its work: transcript quotes, and audio clips of up to 30 seconds each and no more than five minutes in total per publication, with attribution under Section 7. Excerpts must not identify a participant or include removed or redacted content, and must not be offered as data. Any other redistribution of Dataset audio or transcript excerpts requires separate written permission unless an independent legal right applies or Basis has expressly released those exact excerpts under separate terms permitting it. The text of this license and Basis's published citation may be copied to explain the terms or acknowledge the Dataset; that permission does not extend to recordings or records. These restrictions concern the activity, not the industry in which Recipient operates. A data vendor may undertake the permitted research or commercial Model development, but receives no right to broker, resell or redistribute Source Materials. 5. PERSONNEL, INFRASTRUCTURE AND INTERNAL COPIES Recipient may make the internal working copies and backups reasonably needed for permitted uses. Recipient may give Personnel access only as necessary to perform that work, under written confidentiality, security and use obligations at least as protective as this agreement. Recipient is responsible for their compliance. Providers may charge for their work, but may not use Source Materials for their own purposes, other clients or their own general model training. Private cloud storage and compute under those obligations are permitted. Recipient must restrict access, keep sufficient records of copies to carry out required deletions, and withdraw Personnel access and require deletion when their work ends, subject to Section 9's retention exceptions. Do not share personal Hugging Face tokens or credentials. Each person downloading from the Hub must comply with its individual access requirements. Affiliates and collaborators acting for their own purposes must obtain their own license from Basis. They do not become Personnel merely through common ownership or a collaboration. Providing source data to another licensee is still not permitted: that licensee must obtain its copy through Basis's authorized channel. 6. PRIVACY, SPEAKER IDENTITY AND SECURITY Recipient must not attempt to identify or contact a participant, link Dataset records or voices to external identities, reverse pseudonymous identifiers, or reconstruct deliberately removed or redacted content. Recipient must not build an identity or authentication database of the Dataset's participants. Using pseudonymous speaker labels for diarization, speaker separation, splitting or other non-identifying speech research is permitted. Recipient must not impersonate a participant or create or offer a voice clone identifiable as a particular Dataset participant without separate written permission from Basis and all legally required participant authorizations. General speech-synthesis training and non-identifying synthetic voices remain permitted. Internal testing aimed at finding and preventing privacy leakage is permitted if it does not attempt to identify participants, reveal their data to unauthorized parties or reconstruct deliberately removed content. Voice recordings may remain personal data even after names are removed. Recipient must comply with applicable privacy, biometric, intellectual-property and other laws, establish any required legal basis for its own use, and implement any required safeguards for international transfers. This agreement does not itself provide a statutory transfer mechanism or override any participant's rights. The parties' data-protection roles depend on their actual activities and applicable law; where necessary, additional terms must be completed before the affected delivery or processing. Recipient must use reasonable access controls and encryption in transit and at rest, and must not put Source Materials in public storage. Recipient must notify Basis at data@withbasis.co without undue delay, and within 72 hours after learning of unauthorized access, use or disclosure, and reasonably cooperate to contain and remedy it. A shorter applicable legal deadline still applies. Residual identifying information must be protected, reported to Basis and not exploited. 7. ATTRIBUTION AND TRADEMARKS When publicly describing work that uses the Dataset, Recipient must give reasonable attribution to Basis in the relevant paper, model card or equivalent documentation, identifying the Dataset and release or repository revision used. For a commercial Model or service, attribution may be in its documentation or notices page. No credit is required in every generated output or interaction. A suitable form is: "Developed using Basis Conversations 1500, published by Basis" followed by the official repository URL and the release or revision identifier. Preserve this license and supplied rights notices with internal Source Materials. Neither party may use the other's trademarks to imply endorsement or partnership without permission. Factual attribution and legally required disclosures are permitted. 8. RIGHTS, WARRANTIES AND LIMITATIONS Basis will provide only Dataset material it is authorized to license for the uses permitted by this agreement. No rights are granted in a participant's identity, likeness or personal data beyond the rights and lawful permissions that actually apply. Recipient is responsible for its Models and downstream uses. Rights in separately identified third-party material are not expanded by this agreement. Rights independently available under applicable law, including mandatory exceptions, are unaffected to the extent they cannot lawfully be restricted by agreement. Except for Basis's express commitment above and to the extent permitted by law, the Dataset is provided as is and as available, without warranties of accuracy, completeness, merchantability, fitness for a particular purpose or noninfringement. Basis does not warrant that recordings contain no residual personal information, that annotations or transcripts are error-free, or that use will produce a particular result. No indemnity is provided under this free license. 9. DURATION, TERMINATION AND REQUIRED REMOVALS Basis may terminate the affected license for a material breach that Recipient fails to cure within 30 days after written notice describing the breach. Basis may immediately suspend access or the affected use where reasonably necessary to address an ongoing unauthorized disclosure, unlawful use or security incident. Suspension must be proportionate to the issue. Basis has no general right to revoke a compliant license to a delivered release for convenience. Loss of hosting or download access alone does not revoke an existing compliant license. Basis may require removal or restricted use of specifically identified material where reasonably necessary to comply with applicable law, a binding order, or a substantiated privacy, consent or third-party-rights issue. Basis will identify the affected material, explain the basis to the extent legally permitted, and give a reasonable compliance period appropriate to the issue. Recipient must stop the affected use and perform legally required remediation by the applicable deadline. An ordinary change to a future release does not itself withdraw permission for an earlier delivery; mandatory legal obligations still apply. On termination, Recipient must stop using and delete affected Source Materials within 30 days, unless an applicable legal deadline requires earlier action, and confirm completion in writing. Inaccessible disaster-recovery backups may expire under their normal schedule, no later than 90 days, and must not be restored for use. Copies required by law or a legal hold may be retained securely solely for that purpose and deleted when the requirement ends. Personnel have the same duties. Compliant Models and Results created before termination or removal may continue to be used and commercialized. This agreement imposes no routine requirement to retrain, unlearn or destroy such artifacts solely because source data is removed. That protection does not apply to prohibited Source Materials, unlawful uses or outputs, or remediation required by applicable law or a binding order. Ownership, restrictions on retained Source Materials, privacy duties, attribution, liability and dispute provisions survive as needed to give them effect. 10. LIABILITY To the extent permitted by law, neither party is liable under this agreement for indirect, special, consequential or punitive damages or lost profits, and each party's total liability under it is limited to US$1,000. These exclusions and the cap do not apply to fraud, willful misconduct, Recipient's unauthorized sale or disclosure of Source Materials, or liability that cannot lawfully be limited. This section does not restrict available injunctive relief or any participant's or third party's rights under applicable law. 11. GENERAL TERMS Send notices to Basis at data@withbasis.co and to Recipient at the email supplied in the access request, as updated in writing. Notices are effective on acknowledged receipt. Routine access approvals are effective when access is granted after acceptance through the authorized process. California law governs, excluding its conflict-of-laws rules. State and federal courts in San Francisco County, California have exclusive jurisdiction, subject to mandatory applicable law. Nothing here overrides mandatory rights or obligations applicable to participants or public institutions. This agreement and the accepted access request identifying Recipient and the release form the complete agreement for the covered delivery. A separately signed agreement expressly covering that delivery controls in the event of conflict. Revising a webpage does not retroactively alter an accepted version. Later releases may require acceptance of new terms. Recipient may transfer this agreement with a merger or sale of substantially all of the relevant business if the successor accepts its duties in writing and Recipient promptly notifies Basis. A standalone sale or transfer of Source Materials is prohibited. Other assignments require Basis's written permission. If a provision is unenforceable, the remainder continues. Failure to enforce a provision is not a waiver. The parties remain independent. Electronic acceptance records may evidence the agreement.
