WaviTrack Dataset Research and Education Licence Version: v1.0 Effective date: 3 October 2026 Provider and licensor: Franklin Wu, project lead of the WaviTrack Team ("Provider"). Contact: admin@wavitrack.com Project website: https://wavitrack.com/ Copyright (c) 2026 Franklin Wu, to the extent of the rights held by him. Other rights remain with their respective holders. This Licence applies only to access approved by the Provider and accepted under the matching Dataset Access Agreement. Publishing these terms does not, by itself, open Dataset access. 1. Scope and definitions "Dataset" means the WaviTrack data package supplied with this Licence, including motion-capture records, sensor measurements, aligned or processed motion data, SMPL-X parameter files, calibration data, metadata and accompanying dataset documentation, to the extent included. It includes copies and subsets of those materials. It does not mean every file available from the project website or code repositories. "You" means the individual whose application has been approved by the Provider. Approval is personal: it does not automatically license your laboratory, employer, supervisor, students or collaborators. "Approved Purpose" means the non-commercial academic research or educational purpose described in your application and approved by the Provider. A materially different purpose or affiliation requires renewed approval before further use. "Derived Data" means a transformation retaining record-level Dataset content, including trimmed, resampled, calibrated, relabelled, augmented or reformatted records, extracted features and reconstructed motion sequences. Changing the format or removing fields does not remove these restrictions. "Research Outputs" means research findings, aggregate statistics, papers, methods, independently written software and trained models resulting from permitted work. An output that contains or allows recovery of Dataset records remains Derived Data to that extent. Calling material a model, embedding, synthetic dataset or research output does not avoid that rule. 2. Limited grant of permission Subject to approval, your express acceptance of this Licence and the matching WaviTrack Dataset Access Agreement, and continued compliance with both, the Provider grants you a royalty-free, non-exclusive, non-transferable and non-sublicensable permission, within the rights the Provider owns or is authorised to license, to: (a) download and securely store the Dataset; (b) make working and backup copies reasonably necessary for the Approved Purpose; (c) analyse, process and create Derived Data for that purpose; (d) train, validate, evaluate and compare models solely for that purpose; and (e) publish Research Outputs as permitted by section 6. This is a restricted research licence, not an open-data or open-source licence. No ownership is transferred. Receiving a file, having an academic affiliation, verifying an email address or obtaining a copy from another user does not by itself grant permission. An application is not approval. 3. No commercial or industrial use You must not use the Dataset or Derived Data for any commercial or industrial purpose, whether directly or indirectly, for payment or free of charge. Prohibited activities include commercial analysis, benchmarking, model training, fine-tuning, distillation, validation, evaluation, product testing, industrial research and development, consulting, and development, improvement or operation of a commercial product or service. The restriction includes work for or on behalf of a commercial organisation, and work directed towards commercial advantage even if performed at a university or described as research. You must disclose commercial sponsorship, commercial partners and intended commercial beneficiaries when applying; approval under this Licence cannot authorise a commercial purpose. You also agree not to commercially exploit, deploy, sell or license a model, its weights or another data-dependent artefact developed using the Dataset, or use it to provide a commercial service. This is your contractual undertaking; it does not claim that the Provider owns all such outputs. Ordinary academic salaries, tuition fees and public or charitable research grants do not, by themselves, make otherwise permitted academic research or education commercial. They do not excuse any prohibited purpose. This Licence grants no commercial permission; silence or failure to enforce a restriction is not permission. 4. No redistribution or shared access Except for the limited publication permission in section 6 or a non-excludable legal right under section 12, you must not copy for others, distribute, publish, upload, mirror, sell, lend, sublicense, transfer or otherwise make the Dataset or Derived Data available to any other person. This includes public or private repositories, data hubs, shared drives accessible to others, file-transfer links, supplementary materials, model repositories containing training examples, and inclusion in another dataset. It applies to the entire Dataset and to subsets. Do not evade it by making repeated small releases. Each collaborator who needs Dataset access must apply separately and obtain their own copy through the authorised service. Approval of another person does not permit you to redistribute files to them. Do not share passwords, authentication tokens or download links that grant access. Secure institutional computing or contracted cloud infrastructure may be used only for your Approved Purpose, with access restricted to your approved use and operators acting solely to supply that infrastructure under appropriate confidentiality and security obligations. This does not authorise independent use by those operators. Do not upload the Dataset to public AI services or services whose terms allow training on, onward sharing of, or independent use of your uploads. 5. Participant protection and security You must not attempt to identify or re-identify any participant, associate Dataset records with a named or otherwise identifiable individual, or link records with external information for that purpose. Do not contact or attempt to contact a participant through information obtained or inferred from the Dataset. Participant codes do not constitute permission to identify individuals. You must not use the Dataset to build identification or surveillance systems targeting individuals, infer sensitive personal attributes unrelated to the Approved Purpose, or make decisions about an identifiable person's employment, insurance, credit, healthcare or legal status. Do not use it for harassment, discrimination or other harm. Keep copies on appropriately secured systems, restrict access, use secure transfer and protect credentials. Do not bypass access controls, probe other accounts, defeat download authorisation or deliberately overload the service. Necessary automated downloads through an authorised method are not prohibited merely because they are automated. If you discover identifying information, a credible re-identification risk, a leak or unauthorised access, stop the affected processing, restrict access and notify admin@wavitrack.com without undue delay. Do not investigate by identifying further participants or circulate the identifying material. Cooperate reasonably in containment. This reporting duty does not replace any independent legal reporting obligation. 6. Research publications and trained models You may publish papers, theses, methods, non-identifying aggregate statistics and independently written analysis code produced through the Approved Purpose. Cite the WaviTrack paper identified in section 7 and identify the dataset release used. Publication in a journal or conference operated by a commercial publisher is not, by itself, prohibited commercial use. Do not include downloadable participant-level records, motion sequences, calibration files or record-level features in those publications or their supplements. Obtain written permission before publishing participant-level visualisations or examples not expressly supplied for public illustration. Aggregate figures must not enable identification or recovery of restricted records. You may share trained model weights for non-commercial research or education only if they do not contain or permit reasonably practicable recovery of Dataset records or identifying information, and you distribute them under express downstream terms prohibiting commercial or industrial use and redistribution on more permissive terms. State that the model was developed using WaviTrack and that access to the underlying Dataset must be obtained separately. Do not attach a permissive licence that contradicts these obligations. The Provider does not acquire ownership of your independently created Research Outputs merely because you used the Dataset. No prior approval of a paper's scientific conclusions is required. Restrictions on Dataset disclosure, participant protection and your commercial exploitation of data-dependent outputs still apply. 7. Attribution, notices and separate materials In publications materially using the Dataset, acknowledge "WaviTrack dataset" and cite: WaviTrack: Exploiting Body-Area RF Channels for Wearable Human Motion Reconstruction. https://doi.org/10.1145/3830727.3834831 State the dataset version and describe relevant processing or modifications without implying that the Provider validated them. Preserve this Licence and any supplied attribution or third-party notices with permitted copies. Citation does not replace the requirement for permission. Do not imply endorsement by the Provider, the WaviTrack Team or any associated institution. The paper's Creative Commons licence does not license these separately supplied Dataset files. Project code, hardware files, separately published pretrained models and third-party assets are governed by their own stated terms; this Licence does not replace them. SMPL, SMPL-X or other third-party model files, software and assets are not licensed by this document. Obtain any required third-party permissions separately. Distribution of motion parameters does not grant rights to redistribute a third-party body-model package. 8. Compliance and incidents You are responsible for ensuring that your use is lawful and within the Approved Purpose. If Dataset records are personal data in your circumstances, you must satisfy the data-protection obligations applicable to your own processing. Access approval is not a blanket legal basis, ethics approval or international-transfer authorisation. On a reasonable, specific request concerning suspected non-compliance, provide information sufficient to explain your use and protective measures. This does not give the Provider unrestricted access to your systems, unrelated confidential research or personal information. The Provider may seek remedies available under applicable law for breach of contract or infringement of rights that actually apply. This Licence creates no automatic fine, penalty or presumption that every breach is a criminal offence. 9. Suspension, termination and deletion The Provider may suspend access immediately where reasonably necessary to investigate suspected misuse, protect participants, address a security incident or comply with law. Where lawful and practicable, the Provider will explain the reason and allow you to respond. Access may be terminated for a material breach, a false application, an unapproved change of purpose or a legal requirement. A remediable breach should ordinarily be given a reasonable opportunity to be corrected. You may end your participation by contacting the Provider. Closing your account, including because you ask to erase identity information necessary to maintain your approval, ends further access and permission for new Dataset processing. Exercising a privacy right is not itself a breach. On termination, stop using the Dataset and Derived Data and delete accessible copies under your control. Put residual backups beyond active use and remove them through the ordinary secure backup-expiry process. Retain a restricted copy only where required by law, or where the Provider separately agrees in writing to a justified retention requirement. Such retained data must not be used for further research or shared. Ordinary account closure does not require withdrawal of already lawfully published Research Outputs that satisfy section 6. It does not authorise further Dataset use or commercial exploitation of data-dependent outputs. Restrictions concerning disclosure, participant protection, commercial exploitation and retained copies survive as necessary to give them effect. Accrued legal rights are unaffected. 10. Research material and liability The Dataset is experimental research material. It may contain measurement error, omissions, alignment uncertainty, artefacts or bias and may not represent other populations or settings. No particular accuracy, completeness, availability or fitness for a particular purpose is promised. It is not supplied for clinical, safety-critical or operational decision-making. To the extent permitted by applicable law, implied warranties are excluded, and the Provider is not liable for indirect or consequential loss arising from use of, or inability to use, the Dataset. This does not exclude or restrict liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, or any other liability or statutory right that cannot lawfully be excluded or restricted. Any remaining liability is determined under applicable law; there is no automatic entitlement to compensation or blanket waiver of all remedies. 11. Versions and relationship to the Access Agreement This Licence and the Dataset Access Agreement bearing the same version identifier form the agreed dataset-access terms. The Licence governs Dataset use; the Access Agreement governs the application and account process. Its privacy notice explains personal-information handling and is not a grant of Dataset rights or a waiver of privacy rights. A later website edit does not silently or retrospectively replace the terms for an earlier release. Material new terms must be brought to your attention and expressly accepted before they govern further access under that version. A change required by law applies only to the extent the law requires. Keep the Licence supplied with each release. 12. Legal framework and mandatory rights Applicable protections may include copyright under the Copyright, Designs and Patents Act 1988 and database rights under the Copyright and Rights in Databases Regulations 1997. In the EEA, applicable national laws implementing Directive 96/9/EC may provide protection where their qualification and territorial requirements are met. This wording does not assert automatic UK or EEA database protection for every file or raw measurement. The restrictions you expressly accept are also contractual obligations, subject to applicable law. Nothing in these terms excludes or limits a statutory exception, lawful-user entitlement, consumer protection or other right that cannot lawfully be excluded or limited by agreement. This Licence is governed by the law of England and Wales, with the courts of England and Wales having non-exclusive jurisdiction. This does not remove mandatory protections or court rights available to you under applicable law. 13. General provisions and contact If a provision is unenforceable, the remaining terms continue so far as they can operate lawfully. Failure to enforce a provision on one occasion is not a waiver. An individual exception or variation must be expressly agreed in writing by the Provider; general project discussion or a supervisor's informal comment is not permission. This Licence grants no trademark rights, endorsement, partnership or agency. It does not authorise you to bind your institution or anyone else. Do not assign your personal access permission. For permissions, clarification, security reports or account closure, contact admin@wavitrack.com and identify the release and your approved account. Do not email participant records, passwords or access tokens unless a secure method has been agreed.
