4.1 All Course content, including, but not limited to, text, audio, video, images, assessments, and AI tutor responses, is owned by or licensed to Cavua and/or the respective Course authors. Nothing in this Agreement transfers any intellectual property rights to you. Cavua and its licensors reserve all rights not expressly granted in this Agreement. Uploaded Materials and Study Tool Outputs are governed by Sections 4.5 through 4.11.
4.2 Subject to your continued compliance with this Agreement and payment of all applicable fees, you are granted a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use Course content solely for your personal, non-commercial educational purposes. This license terminates automatically upon any breach of this Agreement, the termination of this Agreement, or upon termination or suspension of your account.
4.3 You may not, and may not permit or enable any third party to:
(a) reproduce, distribute, publicly display, publicly perform, transmit, create derivative works from, decompile, disassemble, reverse engineer, or otherwise exploit any Course content, AI tutor output, or Platform feature, in whole or in part, without Cavua's prior written consent;
(b) use any Course content, AI tutor output, Study Tool Output, or other Platform data to train, fine-tune, validate, benchmark, or otherwise develop any machine learning model, artificial intelligence system, dataset, or product, or to develop any product or service that competes with the Platform;
(c) scrape, crawl, index, harvest, or perform any automated text or data mining of the Platform or any content therein;
(d) remove, obscure, or alter any copyright, trademark, or other proprietary notice; or

4.4 If you provide Cavua with any suggestions, ideas, enhancement requests, recommendations, or other feedback relating to the Platform ("Feedback"), you hereby grant Cavua a perpetual, irrevocable, worldwide, royalty-free, fully paid-up, sublicensable, and transferable license to use, reproduce, modify, distribute, and otherwise exploit such Feedback for any purpose, without attribution, compensation, or obligation of any kind to you.
4.5 Uploaded Materials and Study Tools. The Platform may permit you to upload, import, paste, link, or otherwise submit documents, files, text, images, audio, video, and other materials (collectively, "Uploaded Materials") and to use AI-powered features to interact with them, including summaries, question answering, quizzes and other study aids, and conversational AI personas or avatars that discuss the material (collectively, "Study Tools"). Content generated by the Study Tools from or in response to Uploaded Materials is "Study Tool Output." Uploaded Materials are Inputs for purposes of Sections 10 and 11, subject to Section 4.7. Uploaded Materials are not Courses; they are not provided, reviewed, licensed, authorized, or endorsed by Cavua or by any author; and they are not made available to any other user.
4.6 Your Responsibility for Uploaded Materials. You are solely responsible for your Uploaded Materials and for your decision to upload them. Cavua does not verify, and has no obligation to verify, whether you have the right to upload any material, and Cavua is not responsible or liable for any Uploaded Materials. Each time you submit Uploaded Materials, you represent and warrant that: (a) you own the Uploaded Materials; or you have obtained all rights, licenses, consents, and permissions necessary to upload them and to permit Cavua and its service providers (including third-party artificial intelligence model providers) to process them as described in this Agreement; or your upload and use of them as described in this Agreement is otherwise permitted under applicable law; (b) you lawfully acquired the Uploaded Materials and did not obtain them through piracy or other unauthorized copying, or by circumventing any digital rights management, encryption, copy-protection, or other technological protection measure; (c) your upload does not breach any license, terms of service, or other agreement governing the Uploaded Materials, including the terms of any eBook store, publisher, database, learning management system, or educational institution, or any confidentiality or non-disclosure obligation; (d) the Uploaded Materials do not contain personal information of any other person (including the education records of other students) that you are not legally permitted to share, or any information prohibited by Section 10.3; and (e) neither your Uploaded Materials nor your use of the Study Tools infringes, misappropriates, or violates any copyright, trademark, trade secret, privacy, publicity, or other right of any third party, or violates any applicable law or the Acceptable Use Policy. Cavua may ask you to confirm these representations at the time of upload, and any such confirmation forms part of this Agreement.
4.7 License to Process Uploaded Materials. As between you and Cavua, you retain whatever rights you hold in your Uploaded Materials, and Cavua claims no ownership of them. You grant Cavua and its service providers a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, process, analyze, and create derivative works from (such as summaries, excerpts, indexes, embeddings, audio, and persona dialogue) your Uploaded Materials, solely to: (a) provide the Study Tools and related Platform features to you; (b) maintain, secure, and troubleshoot the Platform; (c) detect and prevent abuse and enforce this Agreement; and (d) comply with applicable law. This license continues for so long as your Uploaded Materials remain in your account and for any additional period required for backup, security, or legal compliance purposes. Notwithstanding Section 10.4, Cavua will not (i) use the content of Uploaded Materials to train or fine-tune artificial intelligence models; (ii) use Uploaded Materials to create Courses or make them available to any other user or any author; or (iii) sell, publish, or otherwise commercially exploit Uploaded Materials.
4.8 Use of Study Tool Outputs. Subject to your compliance with this Agreement, you may use Study Tool Outputs solely for your personal, non-commercial educational purposes. Study Tool Outputs may reflect or incorporate portions of your Uploaded Materials, and nothing in this Agreement grants you any rights in any third-party material contained in or reflected by a Study Tool Output. You may not publish, distribute, sell, or otherwise make available to others any Study Tool Output that reproduces or is substantially derived from third-party material in your Uploaded Materials, except as permitted by applicable law. The Study Tools are designed to summarize, explain, and discuss Uploaded Materials rather than to reproduce them, and Cavua may limit, modify, or decline to generate any output, including output that would reproduce substantial verbatim portions of Uploaded Materials. Cavua and its licensors retain all rights in the Platform, the Study Tools, and any AI persona designs, names, voices, and appearances supplied by Cavua.
4.9 AI Personas. Any AI persona or avatar made available through the Study Tools is an automated artificial intelligence feature. It is not a real person, does not speak for or represent the author, publisher, or rights holder of any Uploaded Materials or any other real person, and is not affiliated with or endorsed by any of them, unless Cavua expressly states otherwise. You may not configure, prompt, or use any AI persona to impersonate any real person (including the author of any Uploaded Materials), to create a false impression of endorsement by or affiliation with any real person, or to imitate any real person's voice or likeness without that person's consent.
4.10 No Obligation to Review; Removal; Storage. Cavua has no obligation to screen, monitor, or review Uploaded Materials, but may do so. Cavua may block, remove, restrict, or disable access to any Uploaded Materials or Study Tool Outputs at any time, with or without notice, including in response to a notice under Section 13 or where Cavua believes they violate this Agreement, any applicable law, or any third-party right. Cavua may impose limits on the number, size, type, and retention period of Uploaded Materials. Cavua is not a storage or backup service, and you are responsible for keeping your own copies of your Uploaded Materials. Cavua shall have no liability for any removal, loss, or deletion of Uploaded Materials or Study Tool Outputs.
4.11 Academic Policies. You are solely responsible for ensuring that your use of the Study Tools and Study Tool Outputs complies with the academic integrity, honor code, and other policies of any educational institution, instructor, or program in which you participate. Cavua makes no representation that any such use is permitted.
