6.1. No Proprietary Interest. You acknowledge and agree that:
(a) A shuffled card order (a permutation of 52 integers) is a mathematical fact and does not constitute original creative expression capable of copyright protection;
(b) You have no proprietary, intellectual property, or other legal interest in any specific permutation of playing cards;
(c) The act of shuffling a deck of cards does not create any proprietary right in the resulting order;
(d) Multiple individuals may independently produce the same or similar card orders;
(e) The Shuffle Data derived from Your submission is factual data, not creative work.
6.2. Full Waiver. To the fullest extent permitted by law, You hereby irrevocably waive, release, and forever discharge the Company, its officers, directors, employees, agents, affiliates, successors, assigns, and licensees from any and all claims, demands, actions, causes of action, rights, damages, costs, expenses, and liabilities of any kind or nature whatsoever, whether known or unknown, suspected or unsuspected, disclosed or undisclosed, arising out of or in connection with:
(a) The use, reproduction, distribution, licensing, or commercialisation of Your Shuffle Data;
(b) The inclusion of Your Shuffle Data in the Dataset;
(c) The comparison of Your Shuffle Data with any other submission;

(l) Any claim related to the accuracy or inaccuracy of AI card recognition, scores, rankings, percentiles, or statistical analyses;
(m) Any claim related to the removal, modification, flagging, or exclusion of Your submission.
6.3. Unknown Claims. You expressly waive any rights You may have under any statute or common law principle that would otherwise limit the scope of a general release to claims that are known or suspected at the time of signing. You understand that this release includes claims You may not yet know about.
6.4. No Claim to Uniqueness. You acknowledge that while 52! possible orderings exist, You have no legal right to claim exclusive ownership of any particular ordering. The fact that Your shuffle may be statistically unique does not create any proprietary interest in that ordering.
6.5. Covenant Not to Sue. You covenant and agree that You will not institute, maintain, or assert any claim, action, suit, or proceeding of any kind against the Indemnified Parties in respect of any matter released or waived herein.
7.1. Appearance Release. By submitting a Video Recording, You grant the Company the right to use Your likeness, image, voice, and appearance as captured in the Video Recording for any purpose described in Section 4 (Licence Grant), without further consent, notice, or compensation.
7.2. Third Parties in Videos. If any other person appears in or is identifiable in Your Video Recording, You represent and warrant that:
(a) You have obtained their express, informed consent to be recorded and to the submission of the recording to the Service;
(b) You have informed them of these Terms of Use and the licence grant herein;
(c) They have agreed to the use of their likeness as described herein;
(d) If the person is under 18, You have obtained consent from their parent or legal guardian.
7.3. Environment and Video Content. Your Video Recording must show only your hands and the playing cards. You must ensure that Your Video Recording does not contain:

(f) Any content that could constitute a security risk or breach of any obligation of confidentiality.
Important: Videos are retained for the full duration of the experiment (which may be several years) as verification evidence. If two shuffles produce a close or exact match, video review is essential to confirm authenticity and rule out cheating. To protect your privacy, ensure only your hands and cards are visible.
7.4. Video Retention. Video Recordings are retained for the full duration of the experiment in accordance with Our Privacy Policy. This retention period may be several years, as videos serve as verification evidence for the integrity of the research. You acknowledge that deletion of the video does not affect the licence granted over the Shuffle Data extracted from it.
7.5. Video Anonymisation for Research. Video Recordings may be anonymised (faces and identifiable features removed or obscured, if any) and supplied to third-party researchers for additional research purposes, including computer vision research, card recognition AI training, and shuffle technique analysis. Anonymised videos are stripped of all metadata linking them to Your identity. You consent to this use as part of the licence granted in Section 4.
8.1. When You correct AI-detected card identifications, You create labelled training data consisting of:
(a) The image region containing the card;
(b) The incorrect AI prediction;
(c) Your correct identification.
8.2. You grant the Company the same licence described in Section 4 over all Corrections, including the right to use Corrections for AI and machine learning model training, whether for Our own models or for models developed by or for third parties.
8.3. Corrections may be shared with third parties (including AI companies, computer vision researchers, and card recognition system developers) in anonymised form as part of a training dataset. No personal data will be associated with shared Corrections.
8.4. You acknowledge that once Corrections have been used to train an AI model, the learned patterns cannot be "unlearned" or removed from the model. Deletion of Your account does not reverse the training effect of Your Corrections.
9.1. Inclusion. Upon confirmation of Your card order, Your Shuffle Data will be included in the Dataset. Inclusion is automatic and cannot be opted out of while using the submission feature. If You do not wish Your data to be included, do not submit a shuffle.
9.2. Anonymisation. Before inclusion in the commercial or research Dataset, Your Shuffle Data is anonymised as described in Our Privacy Policy. The anonymised Dataset does not contain Your name, email, video, images, IP address, or device fingerprint.
9.3. Perpetual Retention. Anonymised Shuffle Data will be retained in perpetuity as part of the scientific record. You explicitly consent to this perpetual retention and acknowledge that:
(a) It is necessary for the integrity and reproducibility of the research;
(b) It is a core purpose of the Service that You are aware of before submitting;
(c) Anonymised data is not personal data and is not subject to deletion requests;
(d) Even if You delete Your account, anonymised Shuffle Data from Your submissions will remain in the Dataset;
(e) The retention is irreversible — once anonymised and incorporated, individual records cannot be identified or extracted.
9.4. Informed Consent. You confirm that You have been clearly informed, prior to submitting any content, that anonymised data will be retained forever and may be commercialised. This provision is highlighted in these Terms, Our Terms and Conditions, and Our Privacy Policy.

(h) Any other commercial use of anonymised aggregate data.
10.2. You expressly consent to the Company profiting from the Dataset without any obligation to share revenue with You or any other contributor.
10.3. The Company retains sole discretion over pricing, licensing terms, and choice of licensees for the Dataset.
(a) Your participation in the Service is voluntary and without expectation of payment;
(b) You are not entitled to any compensation, fee, royalty, revenue share, or other payment for Your User Content, Shuffle Data, Corrections, or any other contribution;
(c) No employment, joint venture, partnership, or agency relationship is created between You and the Company by virtue of Your participation;
