Spinscreen Terms of Service

Effective date: April 22, 2026 Version: 2026-04-22

These Terms of Service (the "Terms") are a binding agreement between you and Protogy Labs ("Protogy Labs," "we," "us," or "our") governing your access to and use of Spinscreen — the Spinscreen consumer web app and Progressive Web App (PWA), the Spinscreen Chrome extension, the Spinscreen iOS and Android apps, and the Spinscreen organization console (collectively, the "Service").

Please read these Terms carefully. They include important provisions about how disputes between you and Protogy Labs are resolved, including a mandatory binding arbitration agreement, a class-action waiver, a defensive patent clause, and limitations on our liability. They also include a 30-day right to opt out of arbitration (Section 18). By creating an account, installing the extension or app, or otherwise using the Service, you agree to these Terms.

1. Acceptance and eligibility

1.1 By clicking "I agree" at signup, by installing or using the Spinscreen extension or any Spinscreen mobile app, or by otherwise accessing the Service, you accept these Terms and our Privacy Policy and Acceptable Use Policy.

1.2 You may use the Service only if you are at least 13 years old (or 16 years old if you reside in the European Economic Area, the United Kingdom, or another jurisdiction with a higher age of digital consent). The Spinscreen iOS app is rated 17+ because Watch Party allows public messaging.

1.3 If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms, and "you" includes that organization.

1.4 If you do not agree, do not use the Service.

2. Description of the Service

2.1 Spinscreen provides interactive content ("Experiences") that are synchronized to third-party video and audio you are watching. Spinscreen identifies what you are watching using audio fingerprinting (described in the Privacy Policy, Section 3.3) and, on the Chrome extension, optionally using Direct Sync (Section 9 below).

2.2 Spinscreen is a tool for synchronizing experiences to content you are independently watching on third-party platforms. Spinscreen does not host, stream, or distribute the underlying video or audio content. All such content is delivered to you by the third-party streaming service of your choice (Netflix, Hulu, Disney+, Max, Amazon Prime Video, YouTube, broadcast television, etc.).

2.3 The Service is provided as a beta / evolving product. Features may be added, changed, or removed at our discretion.

3. Accounts, identities, and security

3.1 Organization console accounts. You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account. Notify us promptly at support@spinscreen.io if you suspect unauthorized access.

3.2 Pseudonymous viewer identities. The consumer Service may issue you a pseudonymous identity tied only to a hashed auth token. If you lose the token, the identity is unrecoverable — we have no way to reset it without access to the original token, by design.

3.3 You agree to provide accurate information when creating an account and to keep it up to date.

3.4 You may not share, sell, or transfer your account or auth token.

4. License to use the Service

4.1 Subject to your compliance with these Terms, Protogy Labs grants you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to use the Service for your personal or, if applicable, internal business use.

4.2 You may not, except where expressly permitted by mandatory law (for example, the EU Software Directive Article 6 carve-out for interoperability) and only to the extent permitted:

  • copy, modify, translate, or create derivative works of the Service;
  • reverse engineer, decompile, or disassemble the Service;
  • circumvent, disable, or interfere with security or rate-limiting features;
  • access the Service through automated means, scrape, or harvest content beyond what is exposed by our public APIs;
  • remove or alter proprietary notices;
  • use the Service to develop a competing product or service.

4.3 Open-source components included in the Service are licensed under their respective licenses.

5. User-generated content

5.1 The Service lets you post content — including but not limited to Watch Party chat messages, Experiences, profile data, comments, images, audio, and video (collectively, "User Content").

5.2 You retain ownership of your User Content. You grant Protogy Labs a worldwide, non-exclusive, royalty-free, perpetual, irrevocable, sublicensable, transferable license to host, store, reproduce, modify (only as reasonably necessary for formatting, transcoding, and display), distribute, perform, and display your User Content for the purpose of operating, providing, improving, and promoting the Service.

5.3 You represent and warrant that:

  • you own or have all necessary rights, licenses, consents, and permissions to post your User Content and to grant the license in Section 5.2;
  • your User Content does not infringe any patent, copyright, trademark, trade secret, right of publicity, or other intellectual property or proprietary right of any third party;
  • your User Content does not violate any applicable law or these Terms;
  • you have obtained any necessary releases from individuals depicted in your User Content.

5.4 We are not the publisher of User Content. Protogy Labs acts as an interactive computer service provider under 47 U.S.C. § 230 and equivalent laws. We do not endorse, verify, or assume responsibility for any User Content. We may, but are not obligated to, monitor User Content. We may remove, disable, or refuse to display any User Content at our discretion, with or without notice, including content we determine to violate these Terms or to expose us to legal risk.

5.5 Watch Party messages are public. Messages posted in Watch Party are visible to other viewers of the same content who are within the relevant timestamp range. Do not post anything in Watch Party that you wish to keep private.

5.6 If you post User Content as part of an organization account, the organization controls and is responsible for that content, and the organization grants the license in Section 5.2 alongside you.

6. Acceptable Use

6.1 Your use of the Service is governed by our Acceptable Use Policy, which is incorporated by reference into these Terms.

6.2 Without limiting the Acceptable Use Policy, you may not use the Service to:

  • post unlawful, infringing, defamatory, harassing, threatening, or hateful content;
  • post sexually explicit content, especially any content depicting or sexualizing minors;
  • impersonate any person or entity, or misrepresent your affiliation;
  • transmit malware, viruses, or other harmful code;
  • attempt to identify, de-anonymize, or harass holders of pseudonymous identities;
  • interfere with, disrupt, or attempt to gain unauthorized access to the Service, any user account, or any related systems;
  • use the Service to compete with Protogy Labs or to build a competing product;
  • use the Service in violation of any applicable law, regulation, or third-party right.

6.3 Violation of the Acceptable Use Policy is a material breach of these Terms.

7. Copyright (DMCA)

7.1 We respond to notices of alleged copyright infringement under the U.S. Digital Millennium Copyright Act and equivalent laws. The procedure, the contact information for our designated agent, and the counter-notice process are described at DMCA Procedure.

7.2 We will, in appropriate circumstances, terminate the accounts of users we determine to be repeat infringers.

8. Audio fingerprinting consent

8.1 To enable content recognition, you consent to Spinscreen's use of your device's microphone on the terms described in the Privacy Policy, Section 3.3, including the platform-specific differences:

  • Android, Chrome extension, and iOS (PWA in the app shell): on-device or in-browser landmark hashing and/or neural embeddings; no raw audio is sent to our servers.

8.2 You can revoke microphone access at any time through your operating system's privacy settings. Without microphone access, content recognition will not function.

8.3 The microphone is never used while the Service is in the background.

9. Direct Sync — third-party platform risk

Read this carefully if you enable Direct Sync.

9.1 What Direct Sync is. "Direct Sync" is a Chrome-extension feature that, when you enable it, reads the current playback position from the user-interface elements of streaming services rendered in your browser tab — for example, by reading a timestamp shown next to the player. Spinscreen uses that information to synchronize Experiences to what you are watching, as an alternative to audio fingerprinting.

9.2 Direct Sync may violate the terms of service of the streaming platforms you use it with, including, without limitation, Netflix, Hulu, Disney+, Max, Amazon Prime Video, Peacock, Paramount+, YouTube, and others. Most major streaming services prohibit automated access, scraping, interaction with their user interface by software other than their own, and circumvention of their player.

9.3 You acknowledge and agree that:

  1. You enable Direct Sync at your own risk.
  2. You are solely responsible for compliance with the terms of service of any third-party platform you use Direct Sync with.
  3. Protogy Labs disclaims any and all liability for any account suspension, account termination, throttling, banning, civil action, criminal action, or any other consequence arising from or relating to your use of Direct Sync on any third-party platform.
  4. We make no representation or warranty that Direct Sync is compatible with, authorized by, endorsed by, or sponsored by any streaming service.
  5. Direct Sync is provided as a convenience feature; the audio-fingerprinting flow described in Section 8 is the primary, ToS-neutral sync mechanism.
  6. We may modify, restrict, or remove Direct Sync at any time, including in response to changes by third-party platforms.

9.4 You agree to indemnify Protogy Labs as set forth in Section 14 with respect to any claim arising from your use of Direct Sync.

10. No affiliation with media providers

10.1 Spinscreen is not affiliated with, endorsed by, sponsored by, certified by, or approved by any film studio, television network, music label, broadcaster, streaming service, sports league, or other content provider. References to specific shows, movies, music, athletes, characters, or platforms are made only to describe what content the Service is synchronizing to, and are nominative fair use.

10.2 All trademarks, service marks, trade names, logos, and copyrighted works referenced in or visible through the Service are the property of their respective owners. Use of the Service does not grant you any rights in such marks or works.

11. Shopping, affiliate links, and third-party sellers

11.1 The Service may surface product recommendations and links to third-party retailers. These links are typically generated by affiliate networks including, without limitation, Geniuslink, Skimlinks, and Lykdat. Protogy Labs may earn a commission when you click these links and complete a purchase.

11.2 Protogy Labs is not the seller of any product surfaced by the Service. All purchase, payment, fulfillment, return, refund, and warranty issues are between you and the third-party retailer. Protogy Labs makes no representation or warranty about the accuracy of pricing, availability, fitness for a particular purpose, quality, or any other aspect of products surfaced by the Service.

11.3 Federal Trade Commission disclosure: links displayed by the Service may be affiliate links.

12. AI-generated content

12.1 Some Experiences and product recommendations are generated by AI systems (including Google Gemini and Anthropic's Claude). AI output may be inaccurate, incomplete, or biased. You should not rely on AI-generated content for medical, legal, financial, safety-critical, or other important decisions.

12.2 Protogy Labs makes no representation or warranty regarding the accuracy or appropriateness of AI-generated content surfaced through the Service.

13. Disclaimers

13.1 THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. PROTOGY LABS SPECIFICALLY DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, QUIET ENJOYMENT, AND TITLE, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE.

13.2 WITHOUT LIMITING THE GENERALITY OF SECTION 13.1, WE DO NOT WARRANT THAT:

  • audio fingerprinting will correctly identify any particular content;
  • Direct Sync will work with any particular streaming platform;
  • Experiences will be accurate, current, or free from error;
  • AI-generated content will be accurate or appropriate;
  • the Service will be uninterrupted, secure, timely, or error-free;
  • defects in the Service will be corrected;
  • the Service is free of viruses or other harmful components.

13.3 Some jurisdictions do not allow the disclaimer of certain warranties; in such jurisdictions, the disclaimers in this Section apply to the maximum extent permitted by law.

14. Limitation of liability

14.1 TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL PROTOGY LABS, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, CONTRACTORS, AGENTS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, GOODWILL, DATA, OR USE, ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY, EVEN IF PROTOGY LABS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

14.2 PROTOGY LABS' TOTAL CUMULATIVE LIABILITY TO YOU ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS ($100) OR (B) THE TOTAL AMOUNT YOU PAID PROTOGY LABS FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE LIABILITY.

14.3 The limitations in this Section apply to the fullest extent permitted by law and apply even if any limited remedy fails of its essential purpose. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages or of liability for gross negligence or willful misconduct; in those jurisdictions, our liability is limited to the smallest extent permitted by law.

14.4 You acknowledge that the limitations and exclusions in this Section are an essential basis of the bargain between you and Protogy Labs and that we would not provide the Service to you without them.

15. Indemnification

15.1 You agree to defend, indemnify, and hold harmless Protogy Labs and its officers, directors, employees, contractors, agents, affiliates, licensors, and suppliers from and against any and all claims, demands, suits, proceedings, losses, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to:

  1. your User Content;
  2. your use of Direct Sync, including any violation of any third party's terms of service or other rights;
  3. your use of the Service;
  4. your violation of these Terms or the Acceptable Use Policy;
  5. your violation of any law or any third-party right, including any intellectual property right, right of publicity, or right of privacy;
  6. your misrepresentation of any rights, consents, or licenses you purport to grant under Section 5.

15.2 We reserve the right, at our own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, in which case you agree to cooperate with our defense.

16. Patent provisions

These provisions are designed to deter speculative patent litigation while preserving normal user rights.

16.1 No patent license. No express or implied patent license is granted to you under these Terms, except for the limited operational rights necessary to use the Service in the manner expressly permitted by these Terms.

16.2 Defensive termination. If you (or any entity that you control, that controls you, or that is under common control with you) initiate, voluntarily join, or knowingly assist in initiating a patent infringement claim, action, or proceeding against Protogy Labs, any of its affiliates, any of its users, or any of its licensees, alleging that the Service or any part of it infringes any patent, then all rights and licenses granted to you under these Terms terminate immediately and automatically, without notice.

16.3 Feedback license. Any feedback, suggestions, ideas, or proposals you submit regarding the Service are non-confidential, and you grant Protogy Labs a perpetual, irrevocable, worldwide, royalty-free, fully paid-up, sublicensable, transferable license to use, reproduce, modify, distribute, and otherwise exploit the feedback for any purpose, with no obligation of compensation, attribution, or notice.

16.4 Reservation. Protogy Labs reserves all of its patent and other intellectual property rights. Nothing in these Terms grants any covenant not to assert any patent.

17. Termination

17.1 You may stop using the Service at any time. You may delete your account through the Service or by emailing support@spinscreen.io.

17.2 We may suspend, restrict, or terminate your access to all or part of the Service at any time, with or without notice, including for actual or suspected violation of these Terms or the Acceptable Use Policy, risk of legal liability to us, suspected fraud or abuse, or extended inactivity.

17.3 Upon termination, your right to use the Service ends immediately. Sections that by their nature should survive termination — including Sections 5.2 (UGC license), 11 (affiliate disclaimers), 13 (disclaimers), 14 (limitation of liability), 15 (indemnification), 16 (patent provisions), 18 (dispute resolution), 19 (governing law), and 21 (miscellaneous) — survive.

18. Dispute resolution — binding arbitration and class-action waiver

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES MOST DISPUTES TO BE RESOLVED BY BINDING INDIVIDUAL ARBITRATION AND WAIVES YOUR RIGHT TO A JURY TRIAL OR TO PARTICIPATE IN A CLASS ACTION. YOU HAVE A 30-DAY RIGHT TO OPT OUT (Section 18.8).

18.1 Informal resolution. Before filing arbitration, you agree to first contact us at support@spinscreen.io with a written description of your dispute, your contact information, and the relief you are seeking, and to negotiate in good faith for at least 30 days. Filing demand for arbitration before completing this informal-resolution period is a breach of these Terms.

18.2 Binding arbitration. Except for the carve-outs in Sections 18.5 and 18.6, any dispute, claim, or controversy arising out of or relating to these Terms or the Service ("Dispute") will be resolved by final and binding individual arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules, as modified by these Terms.

18.3 Arbitration procedure.

  • The arbitration will be conducted by one neutral arbitrator experienced in technology disputes.
  • The seat of arbitration is [Protogy Labs' state and county of incorporation — to be filled in], USA, unless you and we agree otherwise. Hearings may be conducted by videoconference at the arbitrator's discretion or your request.
  • The arbitration will be conducted in English.
  • The arbitrator's decision will be in writing and will set forth the essential findings and conclusions.
  • The arbitrator may award any relief that a court could award under applicable law, subject to the limitations in these Terms.

18.4 Class-action waiver. YOU AND PROTOGY LABS AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY ON AN INDIVIDUAL BASIS AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, REPRESENTATIVE, CONSOLIDATED, OR PRIVATE-ATTORNEY-GENERAL (PAGA) ACTION OR PROCEEDING. The arbitrator may not consolidate or join more than one person's claims and may not preside over any form of representative or class proceeding. If a court determines that this class-action waiver is unenforceable as to any particular claim or remedy, then that claim or remedy (and only that claim or remedy) shall be severed from the arbitration and may proceed in court, while all other claims will continue in arbitration.

18.5 Mass-arbitration / batch protocol. If twenty-five (25) or more substantially similar arbitration demands are filed against Protogy Labs by or with the assistance of the same law firm or coordinated counsel within a 60-day period (a "Mass Filing"), the demands will be administered under the AAA Mass Arbitration Supplementary Rules. The parties agree to a bellwether process in which a small number of representative cases are arbitrated first, and the parties will engage in good-faith mediation regarding the remaining cases informed by the bellwether outcomes. Filing fees and other procedural deadlines are tolled while the bellwether process proceeds.

18.6 Small-claims carve-out. Either party may bring an individual action in small-claims court for any Dispute that qualifies, so long as the action remains in that court and is brought only on an individual basis.

18.7 Injunctive relief carve-out. Either party may seek injunctive or other equitable relief in a court of competent jurisdiction to prevent the actual or threatened infringement, misappropriation, or violation of its intellectual property rights.

18.8 Right to opt out of arbitration. You may opt out of the arbitration agreement and class-action waiver in this Section 18 by emailing support@spinscreen.io with the subject line "Arbitration Opt-Out" within 30 days after first accepting these Terms. Your email must include your full name, the email address or username associated with your account, and a clear statement that you wish to opt out of arbitration. Opting out will not affect any other terms.

18.9 Severability of dispute-resolution provisions. If any provision of this Section 18 is held to be invalid or unenforceable, that provision will be severed and the remainder of this Section will remain in full force and effect, except that if the class-action waiver in Section 18.4 is found unenforceable as a whole, then the entire Section 18 (other than this Section 18.9 and Sections 18.6 and 18.7) shall be null and void.

19. Governing law and jurisdiction

19.1 These Terms and any Dispute will be governed by the laws of [Protogy Labs' state of incorporation — to be filled in], United States of America, without regard to its conflict-of-laws principles, and excluding the United Nations Convention on Contracts for the International Sale of Goods.

19.2 For any Dispute not subject to arbitration, you and Protogy Labs consent to the exclusive jurisdiction and venue of the state and federal courts located in [county and state — to be filled in].

19.3 If you are a consumer in the European Economic Area, the United Kingdom, or another jurisdiction with mandatory consumer-protection laws, nothing in these Terms deprives you of the protection of the mandatory laws of your country of residence.

20. Export, sanctions, and government use

20.1 You may not use the Service in violation of U.S. export controls or economic sanctions, and you represent that you are not located in, ordinarily resident in, or a national of any country or region subject to comprehensive U.S. sanctions, and that you are not on any U.S. government list of restricted parties.

20.2 The Service is "commercial computer software" as defined in FAR 12.212 and DFARS 227.7202. U.S. Government users acquire only the rights set forth in these Terms.

21. Miscellaneous

21.1 Entire agreement. These Terms, together with the Privacy Policy, the Acceptable Use Policy, the DMCA Procedure, and any other documents incorporated by reference, constitute the entire agreement between you and Protogy Labs regarding the Service.

21.2 Severability. If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in full force and effect.

21.3 No waiver. Our failure to enforce any provision is not a waiver of our right to do so later.

21.4 No assignment. You may not assign or transfer these Terms or any rights or obligations under them without our prior written consent. We may assign these Terms in connection with a merger, acquisition, financing, or sale of all or substantially all of our assets, or to an affiliate.

21.5 Force majeure. Neither party is liable for delays or failures in performance caused by events beyond its reasonable control.

21.6 Notices. We may give you notice through the Service, by email to the address associated with your account, or by other reasonable means. You may give notice to us at support@spinscreen.io.

21.7 Headings. Section headings are for convenience only and have no legal effect.

21.8 Independent contractors. You and Protogy Labs are independent contractors. These Terms create no partnership, joint venture, agency, or employment relationship.

21.9 Third-party beneficiaries. Except as expressly set forth (for example, our affiliates' indemnification rights under Section 15), there are no third-party beneficiaries to these Terms.

22. Changes to these Terms

22.1 We may update these Terms from time to time. When we do:

  • We will revise the "Effective date" and "Version" at the top.
  • For material changes, we will notify organization-account users by email and post an in-app banner in the consumer PWA at least 14 days before the change takes effect.
  • A change history is maintained at docs/legal/CHANGELOG.md.

22.2 If you do not agree to a material change, you must stop using the Service before the change takes effect. Continued use after the effective date constitutes acceptance.
