+ChainBench-ADD Dataset Terms of Use
+
+Version 1.0
+
+By accessing, downloading, using, or redistributing this repository or any materials made available through it, you agree to these Terms of Use.
+
+1. Scope
+
+These Terms of Use govern the ChainBench-ADD dataset/package release as distributed by the authors through this repository, including released metadata, protocol definitions, split files, benchmark organization, and any benchmark package materials provided here.
+
+These Terms govern this benchmark compilation as distributed from this repository. They do not alter the terms of any upstream materials obtained independently from their original sources.
+
+2. Separate Treatment of Code
+
+Code associated with ChainBench-ADD, including scripts, configurations, and baseline implementations released in the project code repository, is licensed separately under the MIT License and is not relicensed by these Terms of Use.
+
+3. Third-Party Materials and Upstream Terms
+
+ChainBench-ADD is assembled from multiple upstream speech resources and speech-generation systems. All third-party datasets, models, audio, model outputs where applicable, and other external assets remain subject to their original licenses, terms, notices, attribution requirements, and any use restrictions imposed by their respective providers.
+
+These Terms of Use apply only to the ChainBench-ADD release as distributed by the authors and do not replace, override, or weaken any applicable upstream obligations.
+
+No rights are granted in third-party materials beyond those permitted by their original terms. Users are solely responsible for determining whether a contemplated use is permitted under all applicable upstream terms.
+
+4. Permitted Use
+
+Subject to all applicable upstream terms, ChainBench-ADD may be used for:
+
+- research on audio deepfake detection;
+- robustness evaluation;
+- forensic analysis;
+- provenance analysis;
+- benchmarking;
+- academic reproduction and verification.
+
+5. Prohibited Use
+
+ChainBench-ADD must not be used to support or enable:
+
+- impersonation or identity fraud;
+- harassment, social engineering, or deception;
+- unauthorized voice cloning;
+- generation of misleading, deceptive, or fraudulent media;
+- biometric surveillance or other high-risk deployment;
+- training, adapting, or improving systems intended for deceptive speech generation.
+
+For clarity, these restrictions apply to the benchmark package as distributed by the authors and are in addition to any applicable upstream restrictions.
+
+6. Redistribution
+
+Redistribution of the benchmark package, or any subset that includes third-party material, is permitted only to the extent allowed by all applicable upstream terms.
+
+Any redistribution must preserve:
+
+- these Terms of Use;
+- all applicable upstream notices;
+- required attribution and license information;
+- any usage restrictions required by upstream providers.
+
+No redistribution under these Terms may imply broader rights in third-party materials than those granted by the original upstream terms.
+
+7. No Warranty
+
+To the fullest extent permitted by applicable law, ChainBench-ADD is provided "as is" and "as available," without warranty of any kind, whether express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or absence of errors.
+
+8. Limitation of Liability
+
+To the fullest extent permitted by applicable law, the authors, contributors, and distributors of ChainBench-ADD shall not be liable for any claim, damages, or other liability, whether in an action of contract, tort, or otherwise, arising from, out of, or in connection with the benchmark package or the use of or other dealings in it.
+
+9. Termination
+
+Any rights granted under these Terms of Use terminate automatically upon violation of these Terms of Use or any applicable upstream terms.
+
+Upon termination, you must cease use and redistribution of the benchmark package obtained from this repository, except to the extent that continuing rights arise independently from upstream sources under their own terms.
+
+10. Contact
+
+For questions regarding this benchmark release, please contact the dataset authors through the project repository.
+
+11. Entire Understanding
+
+These Terms of Use govern the ChainBench-ADD release as distributed by the authors through this repository. Where third-party materials are involved, the applicable upstream licenses and terms remain controlling with respect to those materials.
