Terms of Use
Effective Date: April 10, 2026
Last Updated: April 10, 2026
1. Agreement to Terms
These Terms of Use (“Terms”) are a legally binding agreement between you and Deep Prediction Inc, doing business as Rehearsals (“Rehearsals,” “Company,” “we,” “us,” or “our”). These Terms govern your access to and use of the Rehearsals Research website at rehearsalsresearch.com, our research interviews and activities, and the related applications and services through which we conduct research and create Twins (collectively, the “Research Services,” and in these Terms the “Services”).
Rehearsals also operates a separate consumer-simulation product for organizational customers at runrehearsals.com, through which those customers run simulations and receive insights. That customer product is governed by its own separate terms and agreements. These Terms do not govern access to or use of the customer product, and use of the Research Services does not grant any rights to it.
By accessing or using the Services, by participating in any research activity, or by clicking to accept these Terms, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree, do not use the Services.
If you are using the Services on behalf of an organization, you represent and warrant that you have authority to bind that organization, and “you” refers to both you and that organization.
Please read Section 6 carefully. If you take part in our research activities, Section 6 describes the rights you grant us in your recordings and your Twin, and the right you keep to delete your data and your Twin at any time. We encourage you to review Section 6 closely and to consult independent legal counsel if you have questions before participating.
2. Definitions
“Participant” means an individual who registers for, accesses, or takes part in any Rehearsals research activity, interview, or panel.
“Business Customer” means an organization that obtains research, insights, or simulation products from Rehearsals, including through Rehearsals’ separate customer product.
“end users” means individuals who access or view research results through a Business Customer or through Rehearsals’ customer product.
“Recordings” means the audio recordings, video recordings, photographs, and still images of a Participant captured by or provided to Rehearsals in connection with the Services.
“Participant Content” means all content, data, and information a Participant provides, submits, or makes available, or that is captured during participation, including interview responses, statements, transcripts, Recordings, survey answers, uploaded files, profile links, and related metadata.
“Twin” means an artificial intelligence representation of a specific individual, created and operated by Rehearsals, that is designed to model how that individual reasons, responds, and behaves in research simulations.
“Derived Works” means all works and materials created, trained, generated, or derived by or for Rehearsals from Participant Content, including Twins, model weights and parameters, embeddings, simulations, research results, summaries, cohorts, and analyses.
“Customer Data” means data a Business Customer provides to Rehearsals.
3. The Research Services
The Rehearsals Research website and the Research Services exist to recruit and interview research participants and to create and operate Twins from their participation. Through the Research Services, Participants take part in recorded interviews, provide responses and related information, and are compensated for doing so.
The Twins and research results created through the Research Services power Rehearsals’ separate consumer-simulation product, which is offered to Business Customers under separate terms. These Terms concern the Research Services and the relationship between Rehearsals and Participants. We may modify, suspend, or discontinue any aspect of the Research Services at any time.
4. Eligibility
You must be at least 18 years old, and at least the age of majority in your place of residence, to use the Services. By using the Services, you represent that you meet this requirement and that all information you provide is accurate, current, and complete. We do not knowingly collect information from, or create Twins of, anyone under 18.
5. Accounts
Certain features require registration. You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. You must notify us immediately of any unauthorized access. We may suspend or terminate accounts at our discretion.
6. Additional Terms for Participants
This Section 6 applies if you take part in any Rehearsals research activity. It is the most important section of these Terms for Participants. Read it carefully.
6.1 Plain-Language Summary
This summary is provided for convenience. The full text of Section 6 controls.
When you participate, we record you on video and audio, we collect your responses, and we use that material to build and operate an AI “Twin” of you: a model designed to simulate how you would think and respond in research simulations. In exchange for the compensation we pay you and your access to the Services, you give Rehearsals ownership of the Recordings and the Twin, and a license to your image, voice, and likeness, for the purposes described in this Section. We may transfer these rights, and your Twin, to another company if Rehearsals is acquired, merges, or sells its assets.
You stay in control of deletion. You can delete your data and your Twin at any time and for any reason, and we will remove your Twin from every system, including the customer product, as explained in Section 6.8.
We keep your name and contact details separate from your Twin, and our customers never receive your raw recordings, your voice or video, or your contact information. They see only modeled, de-identified results, as explained in Section 6.14.
6.2 Compensation and Consideration
Participants may receive compensation as specified at the time of participation. Compensation is contingent on completing the research activity in good faith and providing accurate information. You acknowledge and agree that the compensation paid to you, together with your access to the Services and the mutual promises in these Terms, constitute full, adequate, and complete consideration for all rights you grant under this Section 6. No further or future payment, royalty, or residual is or will be owed to you for any use of Participant Content or Derived Works permitted by these Terms, including use by Rehearsals, its sublicensees, Business Customers, or any successor or assignee.
6.3 Ownership of Recordings, Twins, and Derived Works
To the maximum extent permitted by applicable law, and in consideration of the compensation and access described above, you irrevocably assign and transfer to Rehearsals all right, title, and interest, including all intellectual property rights and copyright, in and to: (a) the Recordings; (b) transcripts of your participation; (c) your Twin; and (d) all other Derived Works.
To the extent any of the foregoing qualifies as a “work made for hire,” it is a work made for hire and Rehearsals is the author. To the extent it does not vest in Rehearsals as a work made for hire, you make a present and irrevocable assignment of it to Rehearsals. You agree to take reasonable actions, and to sign reasonable documents, that Rehearsals requests to perfect or record these rights, and you appoint Rehearsals as your attorney-in-fact, coupled with an interest, solely to execute such documents if you do not do so within a reasonable time after request.
Rehearsals owns its AI models, model weights, and technology as its sole and exclusive property.
Rehearsals’ ownership under this Section, and the license in Section 6.4, are at all times subject to your right to require deletion of your data and your Twin under Section 6.8.
6.4 License of Image, Voice, and Likeness
Certain attributes, including your name, image, voice, and likeness, may not be transferable as property under applicable law. For those attributes, and as a backstop to Section 6.3, you grant Rehearsals and its affiliates a worldwide, royalty-free, fully paid-up, transferable, and sublicensable license to record you, and to use your name, image, voice, likeness, responses, and Participant Content, in all media and formats now known or later developed, to create and operate your Twin and to provide the Research Services and Rehearsals’ customer product as described in these Terms.
This license is perpetual and irrevocable, except that it ends with respect to your data and your Twin if you exercise your deletion right under Section 6.8. This license is exclusive with respect to the creation and operation of a Twin of you, and non-exclusive for all other purposes. Nothing in these Terms restricts your own use of your own name, image, voice, or likeness in your personal and everyday life.
6.5 How We Use Your Participation
Rehearsals and its affiliates, sublicensees, successors, and assignees may use your Recordings, Participant Content, your Twin, and the other rights granted in this Section 6 for the following purposes. This list is intended as a reasonably specific description of how a Twin created from your participation may be used:
- (a) to create, develop, train, calibrate, operate, and maintain a Twin of you;
- (b) to run research simulations in which your Twin is presented with scenarios, questions, products, advertisements, pricing, or other materials, and to collect and analyze the responses;
- (c) to develop, train, evaluate, and improve our AI models, technology, products, and services;
- (d) to produce research results, insights, summaries, cohorts, and analyses, and to provide and commercialize the Research Services and Rehearsals’ customer product to Business Customers;
- (e) to create de-identified, aggregated, and cohort-level materials, and to use and retain those materials;
- (f) to demonstrate the Services to current and prospective Business Customers, investors, and partners; and
- (g) to assign, transfer, and license the foregoing in connection with a corporate transaction as described in Section 8.
Rehearsals does not create synthetic audio or synthetic video that imitates your voice or face, and does not use your image or voice in external advertising that identifies you, without your separate, specific consent.
6.6 Twins
A Twin is an artificial intelligence representation created and operated by Rehearsals that is designed to model how you reason and respond in research simulations. A Twin is not you, is not controlled by you, and does not give you any account, access, or control rights in the Twin or in any result it generates. Rehearsals decides whether, when, and how to create, operate, update, or retire a Twin, subject to your deletion right in Section 6.8.
6.7 Video and Audio Recordings
Your participation is recorded on video and audio. Rehearsals uses these Recordings to confirm that a real person is taking part, to support trust, safety, and fraud prevention, and to create and operate your Twin. The Recordings are held internally by Rehearsals and are not provided to Business Customers or end users, as described in Section 6.14.
Rehearsals does not use the Recordings to identify you to third parties, and does not sell, lease, or trade the Recordings. To the extent any information derived from the Recordings is treated as biometric or other sensitive data under applicable law, Rehearsals collects and uses it only for the purposes described in these Terms, on the basis of your consent, and subject to your deletion right in Section 6.8.
6.8 Your Right to Delete Your Data and Your Twin
You have the right, at any time and for any reason, to require Rehearsals to delete your data and your Twin. You can exercise this right by deleting your account in the app or by contacting legal@runrehearsals.com.
What we delete.When you make a valid deletion request, Rehearsals will, within 30 days: (a) delete your account, your Recordings, your transcripts, your Participant Content, and your Twin from Rehearsals’ systems; and (b) remove your Twin from Rehearsals’ customer product and from any other system in which it has been deployed, so that it can no longer be used in any simulation. Once your Twin is removed, no new recordings, simulations, or research results relating to you will be created.
What we keep. Deletion is forward-looking. Research results, analyses, simulations, and cohort data that were created from your participation before your request are retained by Rehearsals and are not deleted; these are held in de-identified form and do not contain your Recordings or your direct identifiers. Rehearsals also retains: other de-identified and aggregated materials; information Rehearsals must keep to comply with legal, tax, accounting, security, or fraud-prevention obligations, or to establish or defend legal claims; and routine system backups, which cycle out on a regular schedule. Rehearsals is not required to rebuild general AI models that were trained across many Participants and that do not identify you, and cannot retrieve research results that a Business Customer exported or downloaded before your request.
This deletion right is a continuing obligation. It binds Rehearsals and any successor or acquirer, as described in Section 8.
6.9 Waiver of Moral Rights and Publicity Claims
To the maximum extent permitted by applicable law, you waive, and agree not to assert against Rehearsals or its affiliates, sublicensees, successors, or assignees, any moral rights, rights of attribution or integrity, and rights of publicity, in each case solely with respect to the uses authorized by these Terms. You waive any right to inspect or approve any Twin, Derived Work, or research result. You will not bring any claim for defamation, false light, invasion of privacy, or violation of publicity or likeness rights arising from a use authorized by these Terms.
6.10 Participant Representations and Warranties
You represent and warrant that: (a) you are at least 18 years old and at least the age of majority where you reside; (b) you have the full right, power, and authority to grant all rights and licenses in this Section 6; (c) the Participant Content is truthful and accurate and is your own, and your participation and the rights you grant do not and will not infringe or violate the rights of any third party; (d) you are not a party to any agreement, including any agreement with a union, guild, agency, or employer, that conflicts with or limits the rights you grant under these Terms; and (e) you are granting these rights knowingly and voluntarily.
6.11 Independent Review and Voluntary Agreement
You acknowledge that: (a) you have had the opportunity to read Section 6 in full and to ask questions; (b) you have been advised that you may consult independent legal counsel of your choosing, at your own expense, before agreeing to these Terms; (c) you enter into these Terms knowingly, voluntarily, and free of duress; and (d) these Terms are the product of arm's-length dealing.
6.12 Accuracy
You agree to provide truthful and accurate responses. Providing false or misleading information may result in forfeiture of compensation and termination of your access to the Services.
6.13 No Confidentiality
Participant Content is not confidential as between you and Rehearsals, and you acknowledge that research results and de-identified excerpts may be created from your participation and made available to Business Customers in accordance with our Privacy Policy. This does not change the protections in Section 6.14: Business Customers and end users are not provided your raw Recordings, your voice or video, or your direct identifying information.
6.14 Separation of Your Identity from Twins and Results
We design the Research Services so that your direct identifying information is kept separate from the Twins and research results created from your participation.
Your direct identifiers, including your name, email address, telephone number, postal address, and account credentials, are stored separately under access controls. They are not embedded in your Twin, and they are not included in the research results or de-identified excerpts made available to Business Customers or shown to end users. Business Customers and end users do not receive your raw video or audio Recordings, your voice, or your direct identifiers. What they receive are modeled responses, de-identified excerpts, and aggregated or cohort-level results.
Because a Twin is built to model a specific individual, Rehearsals continues to treat the Recordings and the Twin as personal information and protects them accordingly. Rehearsals does not represent that a Twin is anonymous; rather, Rehearsals commits to the access, separation, non-disclosure, and deletion controls described in these Terms.
The commitments in this Section, including the restriction on disclosing raw Recordings, voice, video, and direct identifiers to Business Customers and end users, continue to apply to any successor or acquirer of Rehearsals, as described in Section 8.
7. Related Services and Business Customers
Rehearsals’ consumer-simulation product for organizational customers is a separate service, offered at runrehearsals.com under its own terms of service or a written customer agreement. Those separate terms, and not these Terms, govern Business Customers’ access to and use of that product, any first-party data they provide, and their use of research results.
For clarity, and as described in Section 6.14, Business Customers and end users do not receive your raw Recordings, your voice or video, or your direct identifying information through the Research Services or the customer product. Rehearsals contractually requires Business Customers not to attempt to identify, contact, or re-identify any individual from research results and not to combine research results with other data sets for that purpose. Research results are modeled predictions provided for informational purposes, and Rehearsals does not guarantee that they will accurately predict actual behavior.
8. Corporate Transactions and Transfer of Rights
You expressly acknowledge and agree that all Participant Content, Recordings, Twins, Derived Works, research results, Customer Data, accounts, and all rights, assignments, licenses, and consents granted under these Terms are assets of Rehearsals that may be transferred. In connection with any merger, acquisition, consolidation, reorganization, change of control, financing, investment, sale or transfer of all or substantially all of Rehearsals’ assets or equity, bankruptcy, or similar transaction, Rehearsals may assign, transfer, sell, license, and disclose all of the foregoing to the counterparty, successor, or acquirer, and to that party’s advisors and financing sources for diligence purposes, in each case without further notice to you, without your further consent, and without any additional compensation to you. You consent to this transfer in advance. All rights, assignments, licenses, consents, and waivers granted under these Terms bind you and inure to the benefit of Rehearsals and its successors and assignees, and continue in full force following any such transaction.
As a condition of any such transaction, Rehearsals will require the successor or acquirer to assume and be bound by the obligations in these Terms that protect Participants, including your right to require deletion of your data and your Twin under Section 6.8, and the restriction on disclosing raw Recordings, voice, video, and direct identifiers to Business Customers and end users under Section 6.14. The transfer of rights described in this Section does not authorize a successor or acquirer to disclose that material to Business Customers or end users in raw or identifiable form, and does not reduce your deletion right.
9. Acceptable Use
You agree not to: (a) use the Services for any unlawful purpose; (b) attempt to gain unauthorized access to our systems; (c) interfere with or disrupt the Services; (d) reverse engineer, decompile, or attempt to derive the source code, model weights, or architecture of our technology; (e) use the Services, or copy, scrape, or exploit any research questions, study designs, methodologies, prompts, interview content, results, or other materials obtained through the Services, to build, train, benchmark, or assist a product, model, or service that competes with Rehearsals; (f) use automated means to access the Services without authorization; (g) submit false, misleading, or fraudulent information; (h) impersonate any person or misrepresent your identity or eligibility; or (i) violate the rights of any third party.
10. Intellectual Property
The Services and all associated technology, models, content, and materials, including the Twins, our AI models, and all Derived Works, are owned by Rehearsals or its licensors and are protected by intellectual property laws. Except for the limited rights expressly granted in these Terms, we reserve all rights. You may not use our trademarks, logos, or branding without prior written consent.
Feedback. If you provide suggestions, ideas, or feedback regarding the Services, you grant us a perpetual, irrevocable, worldwide, royalty-free, sublicensable, and transferable right to use that feedback without restriction or compensation.
11. Privacy
Your use of the Services is subject to our Privacy Policy, which is incorporated into these Terms by reference. By using the Services, you consent to the collection, use, sharing, and retention of information as described in the Privacy Policy.
12. Disclaimers
THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT DEFECTS WILL BE CORRECTED.
13. Limitation of Liability
TO THE FULLEST EXTENT PERMITTED BY LAW, IN NO EVENT SHALL REHEARSALS, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO THESE TERMS OR YOUR USE OF THE SERVICES, REGARDLESS OF THE THEORY OF LIABILITY.
TO THE EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID OR WERE PAID BY US IN THE TWELVE MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED DOLLARS ($100).
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU. NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED UNDER APPLICABLE LAW.
14. Indemnification
You agree to indemnify, defend, and hold harmless Rehearsals and its affiliates, officers, directors, employees, and agents from any claims, damages, losses, liabilities, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your use of the Services; (b) your violation of these Terms; (c) your violation of any applicable law or regulation; or (d) your breach of any representation or warranty in these Terms.
15. Dispute Resolution
Please read this Section carefully. It affects how disputes are resolved and requires arbitration on an individual basis.
Informal Resolution. Before starting an arbitration, you agree to first contact us at legal@runrehearsals.com and attempt to resolve the dispute informally for at least 60 days.
Arbitration Agreement. You and Rehearsals agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Services shall be resolved by binding arbitration administered by the American Arbitration Association (“AAA”) under its Consumer or Commercial Arbitration Rules, as applicable. The arbitration shall be conducted in Wilmington, Delaware, or another mutually agreed location, or by videoconference where available. The arbitrator’s decision shall be final and binding, and judgment may be entered in any court of competent jurisdiction.
Class Action Waiver. YOU AND REHEARSALS AGREE THAT DISPUTES SHALL BE RESOLVED ONLY ON AN INDIVIDUAL BASIS AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate claims or preside over any class or representative proceeding.
Mass Arbitration. If 25 or more similar arbitration demands are submitted by or with the coordination of the same or coordinated counsel, the demands shall be administered in staged batches as permitted by the applicable AAA rules, and the parties will cooperate in good faith to apply a batching and bellwether process.
Exceptions. Either party may seek injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property or confidential information.
Opt-Out. You may opt out of this arbitration agreement by sending written notice to legal@runrehearsals.com within 30 days of first accepting these Terms. If you opt out, disputes will be resolved in the state or federal courts located in Delaware.
16. Governing Law
These Terms and any disputes arising hereunder are governed by the laws of the State of Delaware, without regard to conflict-of-law principles, except that the Federal Arbitration Act governs Section 15. This choice of law does not deprive you of the protection of mandatory consumer or data protection laws of your place of residence that cannot be derogated from by agreement.
17. Term and Termination
We may suspend or terminate your access to the Services at any time, with or without cause and with or without notice. Upon termination, your right to use the Services ceases immediately. All provisions that by their nature should survive termination survive, including Sections 2, 6, 7, 8, 10, 12, 13, 14, 15, 16, 19, and 20. For clarity, your right to delete your data and your Twin under Section 6.8 survives termination and account closure.
18. Changes to Terms
We may modify these Terms at any time. We will provide notice of material changes by updating the effective date or through other appropriate means. Changes do not retroactively reduce rights, assignments, licenses, or consents already granted to Rehearsals with respect to Participant Content or Derived Works created before the change, and do not reduce your deletion right. Your continued use of the Services after changes take effect constitutes acceptance.
19. Severability and Reformation
If any provision of these Terms is held invalid, unlawful, or unenforceable, that provision shall be modified and reformed to the minimum extent necessary to make it valid, lawful, and enforceable while preserving its intent and economic effect as closely as possible. If it cannot be reformed, it shall be severed, and the remaining provisions remain in full force. The invalidity of a provision in one jurisdiction does not affect its validity in any other jurisdiction.
20. General Provisions
Entire Agreement. These Terms, together with our Privacy Policy, the participant consent and release, and any applicable service agreement, are the entire agreement between you and Rehearsals regarding the Services.
Waiver. Our failure to enforce any provision is not a waiver of that or any other provision.
Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign or transfer these Terms, in whole or in part, freely and without restriction, including as described in Section 8.
No Third-Party Beneficiaries. Except for Rehearsals’ affiliates, sublicensees, successors, and assignees, these Terms create no third-party beneficiary rights.
Force Majeure. We are not liable for any failure or delay caused by events beyond our reasonable control.
Notices. We may provide notices to you by email or through the Services. You may contact us as set out below.
