Terms of Service

Effective April 18, 2026
Updated July 9, 2026

These Terms of Service (the "Terms") form a binding agreement between you and Official Unofficial, Inc., a Delaware corporation with its principal place of business in New York ("Official Unofficial," "we," "us," or "our"). They govern your access to and use of our websites, including officialunofficial.com and makechain.net; the Uno iOS application ("Uno"); the Makechain protocol and any related developer tools ("Makechain"); and any other products, APIs, features, or services that link to these Terms (collectively, the "Services").

Please read these Terms carefully. They include an arbitration agreement and class-action waiver (Section 13) that affect your legal rights. You may opt out of arbitration within 30 days of first accepting these Terms by following the procedure in Section 13.

1. Acceptance of the Terms

By creating an account, clicking "I agree" (or a similar button), downloading or installing Uno, interacting with Makechain through our interfaces, or otherwise accessing or using the Services, you agree to these Terms and to our Privacy Policy. If you are using the Services on behalf of an entity, you represent that you have authority to bind that entity, and "you" refers to that entity. If you do not agree, do not access or use the Services.

If you use Uno on an Apple device, our End User License Agreement (the "EULA") also applies and is incorporated into these Terms by reference. In the event of a conflict between these Terms and the EULA with respect to your use of Uno on Apple platforms, the EULA controls.

2. Eligibility

The Services are not directed to children. You must be at least 13 years old to use Uno, and at least the age of digital consent in your jurisdiction (for example, 16 in parts of the European Economic Area). Certain features, including any that require a connected wallet or onchain interaction with Makechain, may require you to be 18 or older. You represent that you meet the applicable age requirement and that you are not barred from receiving the Services under the laws of the United States or your jurisdiction.

We comply with the Children's Online Privacy Protection Act ("COPPA") and do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, please contact privacy@officialunofficial.com.

3. Accounts and Security

To use certain features you must create an account. You agree to provide accurate, current, and complete information, to keep it up to date, and to safeguard your credentials (including passkeys, signing keys, and session tokens). You are responsible for all activity that occurs under your account. You must notify us promptly at security@officialunofficial.com of any suspected unauthorized use of, or access to, your account.

We may refuse, reclaim, or require you to change a username or handle for any reason, including if it violates these Terms or a third party's rights. We may also delete or suspend accounts that remain inactive for an extended period after reasonable notice to your registered contact address.

4. User Content and License to Us

The Services let you submit, upload, post, broadcast, or otherwise make available text, images, video, audio, casts, replies, reactions, profile information, and other content (collectively, "User Content"). As between you and us, you retain all rights you have in your User Content. You represent and warrant that you own or have the necessary rights to your User Content and that it, and our authorized use of it, does not violate these Terms, applicable law, or any third party's rights.

You grant Official Unofficial a worldwide, non-exclusive, royalty-free, fully paid-up, transferable, and sublicensable license to host, store, reproduce, modify (for formatting and technical purposes), create derivative works from (such as thumbnails, translations, and previews), distribute, publicly perform, publicly display, and otherwise use your User Content for the limited purposes of operating, providing, improving, securing, and promoting the Services, and as otherwise described in the Privacy Policy. This license continues for as long as your User Content is stored on our systems or remains accessible through the Services, and survives termination to the extent necessary for back-ups, legal compliance, enforcement of these Terms, and technical propagation.

Public networks. Some Services broadcast your User Content to public, decentralized networks, including the Farcaster protocol used by Uno and the Makechain protocol. Content broadcast to a public network is, by design, visible to anyone and may be copied, retained, and redistributed by third parties and by the network itself. We cannot remove content from a public network. When you delete content through our interfaces, we will remove it from systems we control and send an offchain or onchain deletion request as applicable, but we cannot guarantee removal from nodes, caches, or third-party services we do not operate.

Feedback. If you send us ideas, suggestions, or feedback, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use them for any purpose without obligation or compensation to you.

5. Acceptable Use

You agree that you will not, and will not attempt to:

use the Services in violation of any applicable law, regulation, or third-party right, including intellectual property, privacy, publicity, export-control, and sanctions laws;
post or transmit content that is unlawful, defamatory, obscene, sexually explicit involving minors, harassing, threatening, or that promotes violence, self-harm, or discrimination;
engage in spam, phishing, impersonation, fraudulent behavior, manipulation of metrics or feeds, or deceptive use of AI-generated content;
infringe, misappropriate, or otherwise violate the intellectual property or privacy rights of others;
access, scrape, index, or collect data from the Services by automated means without our prior written consent, except as expressly permitted by documented public APIs and their rate limits;
reverse engineer, decompile, disassemble, or attempt to derive the source code, underlying models, keys, or algorithms of the Services, except to the extent this restriction is prohibited by applicable law;
probe, scan, or test the vulnerability of the Services, or breach or circumvent any security or authentication measures, except as expressly permitted by our Vulnerability Disclosure Policy;
interfere with or disrupt the Services or the networks or systems connected to them, including by deploying malware, denial-of-service attacks, or excessive load;
use the Services to build a competing product or to train a machine learning model, except as expressly permitted in writing by us;
use the Services while located in, or if you are a resident or national of, any country or region subject to comprehensive U.S. sanctions (including as of the effective date Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, Luhansk, and Kherson regions of Ukraine), or if you are listed on any U.S. government list of prohibited or restricted parties.

We may investigate and take enforcement action for any suspected violation, including removing content, limiting visibility, suspending or terminating accounts, and cooperating with law enforcement.

6. Intellectual Property

Our IP. The Services, including all software, text, graphics, logos, trademarks, and the look and feel, are owned by Official Unofficial or its licensors and are protected by copyright, trademark, and other laws. Subject to your compliance with these Terms, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to access and use the Services for your personal or internal business use. All rights not expressly granted are reserved. "Uno," "Makechain," "Official Unofficial," and related logos are our trademarks.

Your IP. You retain all rights in your User Content, subject only to the licenses you grant in these Terms.

Open-source components. The Services include open-source software governed by separate license terms, which control solely with respect to the applicable components.

Copyright complaints. We respond to notices of alleged copyright infringement under the Digital Millennium Copyright Act. Notices and counter-notices should be sent to dmca@officialunofficial.com and must include the information required by 17 U.S.C. § 512. We may terminate repeat infringers in appropriate circumstances.

7. Third-Party Services and Links

The Services may contain links to, or integrate with, third-party websites, applications, networks, wallets, or services (including Apple, wallet providers, analytics providers, and public protocols such as Farcaster and Makechain nodes we do not operate). We do not control and are not responsible for those third parties, and your use of them is governed by their terms. The inclusion of a link or integration is not an endorsement.

8. Termination

You may stop using the Services at any time and may delete your account through in-product controls or by contacting support. We may suspend, limit, or terminate your access to the Services, in whole or in part, at any time, with or without notice, if we reasonably believe that you have violated these Terms, that your account poses a security or legal risk, or that continued provision is not commercially reasonable. We may also discontinue any portion of the Services at our discretion.

On termination, your right to access the Services ends, but the following provisions survive: Section 4 (to the extent necessary for our licenses and for content already broadcast to public networks), Sections 6, 9, 10, 11, 12, 13, 14, and 15. Content you broadcast to public networks may remain on those networks indefinitely.

9. Disclaimers

THE SERVICES, INCLUDING ALL CONTENT AND FEATURES, ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS. TO THE FULLEST EXTENT PERMITTED BY LAW, OFFICIAL UNOFFICIAL AND ITS LICENSORS DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, AND STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR TRADE USAGE.

WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE; THAT DEFECTS WILL BE CORRECTED; OR THAT THE SERVICES OR ANY SERVERS THAT MAKE THEM AVAILABLE ARE FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS. DECENTRALIZED NETWORKS, BLOCKCHAINS, AND CRYPTOGRAPHIC SYSTEMS HAVE INHERENT RISKS; YOU USE THEM AT YOUR OWN RISK. NOTHING WE SAY OR DO CREATES A WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you.

10. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER OFFICIAL UNOFFICIAL NOR ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR LICENSORS WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUES, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY, AND WHETHER OR NOT WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES WILL NOT EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS ($100) OR (B) THE AMOUNTS YOU PAID TO US FOR THE SERVICES IN THE TWELVE (12) MONTHS IMMEDIATELY BEFORE THE EVENT GIVING RISE TO THE CLAIM.

These limitations do not apply to liability that cannot be limited or excluded under applicable law (for example, in some jurisdictions for death or personal injury caused by negligence, fraud, or willful misconduct), to our indemnification obligations, if any, or to your indemnification obligations under Section 11.

THE LIMITATIONS IN THIS SECTION 10 ARE AN ESSENTIAL BASIS OF THE BARGAIN BETWEEN YOU AND US AND APPLY EVEN IF A LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

11. Indemnification

You will indemnify, defend, and hold harmless Official Unofficial and its officers, directors, employees, and agents from and against any third-party claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to (a) your User Content, (b) your use of the Services, (c) your violation of these Terms, or (d) your violation of any law or any rights of a third party. We may assume the exclusive defense and control of any matter subject to indemnification, in which case you will cooperate with us. You will not settle any matter without our prior written consent.

12. Governing Law and Venue

These Terms and any dispute arising out of or relating to them or the Services are governed by the laws of the State of Delaware, without regard to its conflict-of-laws principles, and by applicable U.S. federal law. Subject to the arbitration agreement in Section 13, any judicial proceeding permitted under these Terms must be brought exclusively in the state or federal courts located in New York County, New York, and you and we consent to the personal jurisdiction of those courts. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

13. Dispute Resolution; Binding Arbitration; Class Waiver

13.1 Informal resolution

Before starting an arbitration, you and we agree to try to resolve any dispute informally for at least sixty (60) days. You will send a written notice of your dispute to legal@officialunofficial.com describing the nature and basis of the claim and the relief sought, and providing a telephone number where you can be reached. We will send our notice to the contact information you have on file. If we cannot resolve the dispute within sixty days, either party may proceed to arbitration. The statute of limitations and any filing fees will be tolled while the parties engage in the informal resolution process.

13.2 Agreement to arbitrate

Except for the Excluded Disputes in Section 13.5, you and we agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Services, including their formation, interpretation, breach, or termination, will be resolved exclusively by final and binding individual arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules and, where applicable, the AAA Mass Arbitration Supplementary Rules then in effect. The Federal Arbitration Act, 9 U.S.C. §§ 1 et seq., governs the interpretation and enforcement of this Section 13.

The arbitration will be held in New York County, New York, or by telephone or videoconference, or for claims of $10,000 or less, by documents only, at your election. The arbitrator, not any federal, state, or local court or agency, has exclusive authority to resolve any dispute relating to the interpretation, applicability, enforceability, or formation of this Section 13, except that a court may decide the enforceability of the class-action waiver in Section 13.4.

13.3 30-day opt-out

You have the right to opt out of this arbitration agreement. To opt out, you must send written notice of your decision to opt out within 30 days after you first accept these Terms. Your notice must include your full name, the email address or account identifier you use with the Services, and a clear statement that you wish to opt out of arbitration. Send the notice by email to legal@officialunofficial.com with the subject line "Arbitration Opt-Out," or by mail to Official Unofficial, Inc., Attn: Legal — Arbitration Opt-Out, 116 Remsen St., Brooklyn, NY 11201. Opting out of arbitration will not affect any other provision of these Terms. If you opt out, you may continue to use the Services, and any dispute will be resolved in the courts identified in Section 12.

13.4 Class-action and representative-action waiver

You and we agree to bring claims against each other only in an individual capacity and not as a plaintiff or class member in any class, consolidated, collective, or representative proceeding. The arbitrator may not consolidate more than one person's claims (except as provided in Section 13.6 for batched mass arbitrations) and may not preside over any form of representative or class proceeding. If this waiver is found to be unenforceable with respect to any claim for public injunctive relief, that claim (and only that claim) will be severed and brought in the courts identified in Section 12, and any other claims will proceed in arbitration.

13.5 Excluded Disputes

Notwithstanding anything to the contrary, the following disputes are not subject to arbitration (the "Excluded Disputes"): (a) any claim that may be brought in small-claims court, provided it remains in that court and proceeds on an individual (non-class) basis; (b) any dispute relating to the validity, enforceability, or infringement of either party's intellectual property rights, which may be brought in the courts identified in Section 12; and (c) any dispute that applicable law prohibits from being arbitrated.

13.6 Mass-arbitration protocol

If 25 or more similar arbitration demands are filed against us by or with the assistance of the same law firm or coordinated group of counsel within a 60-day period (a "Mass Filing"), the parties agree that the AAA Mass Arbitration Supplementary Rules (or successor rules) will apply, including any applicable mass-arbitration fee schedule, and the parties will cooperate in good faith to implement a staged or bellwether process designed to resolve claims efficiently and to reduce duplicative cost. If the AAA declines to administer the Mass Filing under its rules, either party may elect to have the Mass Filing resolved by a court of competent jurisdiction under Section 12, on an individual basis. Nothing in this Section 13.6 expands the arbitrator's authority to preside over class, consolidated, collective, or representative proceedings.

13.7 Severability of this Section

If any portion of this Section 13 (other than the class-action waiver in Section 13.4) is found to be unenforceable, that portion will be severed, and the remainder of this Section 13 will remain in effect. If the class-action waiver in Section 13.4 is found to be unenforceable as to a particular claim or request for relief, that claim or request will be severed from arbitration and brought in the courts identified in Section 12; all other claims will proceed in arbitration.

13.8 Consumers in other jurisdictions

If you are a consumer residing in the European Economic Area, the United Kingdom, or another jurisdiction whose law restricts the enforceability of pre-dispute arbitration agreements or class-action waivers in consumer contracts, nothing in this Section 13 deprives you of rights that cannot be waived under that law, and you may bring claims in the courts of your country of residence where applicable law so requires.

14. Changes to the Terms

We may update these Terms from time to time. If we make material changes, we will provide reasonable advance notice, such as by posting a notice in the Services, updating the "Last updated" date, and/or emailing the address associated with your account. Non-material changes take effect when posted. Your continued use of the Services after changes take effect constitutes your acceptance of the updated Terms. If you do not agree, you must stop using the Services.

15. Miscellaneous

Entire agreement. These Terms, the EULA (where applicable), and the Privacy Policy constitute the entire agreement between you and us regarding the Services and supersede any prior agreements.

Severability. If any provision is held unenforceable, it will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect.

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

Assignment. You may not assign 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, reorganization, or sale of all or substantially all of our assets, or by operation of law.

Force majeure. We are not liable for any delay or failure to perform caused by events beyond our reasonable control, including natural disasters, war, terrorism, civil unrest, labor conditions, government actions, internet or utility failures, or outages of third-party networks or protocols.

Notices. We may give you notice by email, through the Services, or by posting on officialunofficial.com. You may give us notice at legal@officialunofficial.com or at the address below.

Relationship. These Terms do not create any agency, partnership, joint venture, or employment relationship.
