Rivus — Terms of Service Effective Date: June 3, 2026 Last Updated: June 3, 2026 These Terms of Service ("Terms") are a binding agreement between you and Leo Rivus LLC, a Texas limited liability company ("Rivus," "we," "our," or "us"), governing your use of the Rivus mobile application and related services (the "App"). By downloading, installing, creating an account, or otherwise using the App, you agree to these Terms and to our Privacy Policy (rivusapp.com/privacy), and you acknowledge that your electronic acceptance has the same effect as a signature. If you do not agree, do not use the App. Please read Section 15 carefully. It requires most disputes to be resolved by binding individual arbitration and waives class actions and jury trials. You may opt out of arbitration within 30 days as described there. 1. Eligibility You must be at least 16 years old to use Rivus. By using the App, you represent that you meet this requirement, that you are not barred from using it under applicable law, and that the information you provide is accurate. If you are between 16 and the age of majority where you live, you should review these Terms with a parent or guardian. 2. The Service Rivus provides fly-fishing information and tools, including river conditions (streamflow and water temperature from USGS, weather from the National Weather Service), hatch predictions, fly recommendations, river and access information, a trip log, and Eddy, an AI-powered advisor. Features, data coverage, and availability may change at any time, and some rivers or regions may not be supported. We may modify, suspend, or discontinue any part of the App at any time. 3. Accounts You are responsible for keeping your account credentials confidential and for all activity under your account. You may create an account with an email and password or via Sign in with Apple. Notify us at support@rivusapp.com if you suspect unauthorized use. You may delete your account at any time in Settings → Account → Delete Account. 4. Subscriptions (Rivus Pro) The App offers a free tier and an optional paid subscription, Rivus Pro, which unlocks additional features (such as Eddy's open-ended AI answers, photo identification, the multi-day forecast, access-point details, trip planning, and offline data). Rivus Pro is an auto-renewing subscription sold as an in-app purchase through the Apple App Store. • Purchase and price. The subscription title, length (billing period), and price — including the price per unit where applicable — are shown in the App and on the App Store purchase screen before you buy. Payment is charged to your Apple ID account when you confirm the purchase. • Free trial. Rivus Pro may be offered with a free trial. If you do not cancel at least 24 hours before the trial ends, the subscription automatically converts to a paid subscription and your Apple ID is charged the then-current price. Any unused portion of a free trial is forfeited if you purchase a subscription during the trial period. • Automatic renewal. Your subscription renews automatically for successive periods at the then-current price unless you cancel at least 24 hours before the end of the current period. Your Apple ID is charged for renewal within 24 hours before the period ends. • Manage or cancel. You can manage or cancel your subscription at any time in your Apple ID account settings (App Store → your account → Subscriptions). Cancellation takes effect at the end of the current billing period. Deleting the App does not cancel your subscription. • Refunds. Purchases are processed by Apple and are subject to Apple's refund policies; requests are made to Apple, not to Rivus. Except where required by law, payments are non-refundable. • Changes. If we change the subscription price, Apple will notify you and, where required, seek your consent before the change takes effect; otherwise the change applies to the next renewal. 5. The Eddy Advisor and AI Content Eddy is an artificial-intelligence system, not a human, and its responses — like other App outputs generated from data and AI — are provided for general informational purposes only. They may be inaccurate, incomplete, or out of date. Eddy is not a substitute for your own judgment, a licensed guide or instructor, a medical, legal, or financial professional, or official sources. You are solely responsible for the decisions you make based on the App, and you agree to independently verify anything that affects your safety, your spending, or your compliance with the law. Eddy is limited to fly-fishing topics and may decline or be unable to help with anything else. 6. Fishing Regulations and Safety — IMPORTANT • Regulations. Fishing regulations (seasons, limits, gear restrictions, access, licensing, and special rules) change frequently and vary by water and jurisdiction. The regulations information in the App is a convenience reference only and may be wrong or outdated. You are responsible for knowing and following all applicable regulations, and for verifying them with the relevant state fish & wildlife agency before you fish. • Safety and assumption of risk. Fishing, wading, and being near or on the water are inherently dangerous activities. Water levels, weather, and terrain can change rapidly. The App's conditions, forecasts, and advice do not guarantee safe conditions. You assume all risks associated with your activities, and, to the fullest extent permitted by law, you agree that Rivus is not responsible for any injury, loss, or damage arising from your use of the App or your fishing activities. • Conservation. Any guidance on fish handling and catch-and-release is informational; follow applicable law and use your own judgment to protect the fishery. 7. Your Content You retain ownership of the content you submit (trip logs, condition observations, notes, photographs, and feedback). By submitting content, you grant Rivus a worldwide, non-exclusive, royalty-free, sublicensable license to host, store, reproduce, adapt, and use that content to operate, provide, and improve the App, and to create and use anonymized and aggregated information derived from it as described in our Privacy Policy. You represent that you have the rights to submit your content and that it does not violate any law or any third-party right. Do not submit unlawful, infringing, deceptive, or harmful content. We may remove content that violates these Terms. 8. Acceptable Use You agree not to: use the App for any unlawful purpose; reverse engineer, decompile, scrape, or attempt to extract the App's data or source except to the extent that restriction is prohibited by law; use the App or its data to build, train, or benchmark a competing product or model; interfere with or disrupt the App or its infrastructure, or circumvent its rate limits or security; misuse Eddy (including attempts to extract system prompts, jailbreak or manipulate the AI, generate harmful or off-topic content, or evade usage limits); or use the App to harm the fishery, other anglers, or private property. We may suspend or terminate access for violations. 9. Intellectual Property The App — including its software, design, text, databases, and content (excluding your content and third-party data) — is owned by Rivus and protected by intellectual-property laws. We grant you a limited, personal, non-transferable, non-sublicensable, revocable license to use the App for your personal, non-commercial use, consistent with these Terms and the Apple-required terms in Section 16. All rights not expressly granted are reserved. 10. Third-Party Data and Services The App incorporates publicly available data from third parties (including USGS, the National Weather Service, GBIF, and state agencies) and relies on third-party services (including Apple, Supabase, Anthropic, RevenueCat, Sentry, and Mapbox). Third-party data and services are provided "as is," and we do not control and are not responsible for their accuracy, availability, or practices. Your use of those services may also be subject to their own terms. 11. Disclaimers To the fullest extent permitted by law, the App and all content are provided "as is" and "as available," without warranties of any kind, express or implied, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the App will be uninterrupted, secure, error-free, or accurate, or that any conditions, forecasts, hatch predictions, or advice will be correct. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you. 12. Limitation of Liability To the fullest extent permitted by law, Rivus and its owners, members, employees, and suppliers will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, or goodwill, arising from or related to your use of (or inability to use) the App. Our total liability for all claims relating to the App will not exceed the greater of (a) the amount you paid us (or paid Apple for Rivus Pro) in the 12 months before the event giving rise to the claim, or (b) USD $50. Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable law (for example, liability for gross negligence, willful misconduct, fraud, or — where applicable — personal injury). Some jurisdictions do not allow certain limitations, so parts of this Section may not apply to you. 13. Indemnification To the extent permitted by law, you agree to indemnify and hold harmless Rivus and its owners and personnel from any third-party claims, losses, liabilities, and reasonable expenses (including reasonable attorneys' fees) arising from your content, your misuse of the App, or your violation of these Terms or of any law or third-party right. 14. Termination You may stop using the App at any time and delete your account in-app. We may suspend or terminate your access if you materially violate these Terms or if reasonably necessary to protect the App, our users, or third parties, or to comply with law. If we terminate your account without cause while you have paid subscription time remaining, contact us and we will help you request a refund of the unused portion through Apple. Sections that by their nature should survive termination (including Sections 5–13, 15, 16, and 18) will survive. 15. Governing Law and Dispute Resolution 15.1 Governing law. These Terms are governed by the laws of the State of Texas, without regard to its conflict-of-laws rules, except that the Federal Arbitration Act governs Section 15.3. 15.2 Informal resolution first. Before starting an arbitration or a small-claims case, you agree to first email us at support@rivusapp.com with a description of the dispute and to give us 60 days to resolve it informally. Many disputes can be resolved this way. Any applicable statute of limitations is tolled while the parties work through this informal-resolution period. 15.3 Binding individual arbitration. If we can't resolve a dispute informally, you and Rivus agree that any dispute arising out of or relating to these Terms or the App will be resolved by binding arbitration on an individual basis, except as provided in Sections 15.4–15.5 and 15.8. The arbitration will be administered by a recognized, neutral arbitration provider (such as the American Arbitration Association under its Consumer Arbitration Rules), and may be conducted by phone, video, or written submissions, or in person in the county where you live. Payment of arbitration fees is governed by the administering provider's consumer rules; for claims those rules cover, Rivus will pay the arbitration fees those rules require it to pay. The arbitrator decides all issues, except that a court decides the enforceability of Section 15.6 (class-action waiver). Judgment on the award may be entered in any court with jurisdiction. 15.4 Small-claims exception. Either party may bring an individual claim in small-claims court if it qualifies. 15.5 Your right to opt out of arbitration. You may opt out of Section 15.3 (and 15.6) by emailing support@rivusapp.com with the subject line "Arbitration Opt-Out," including your name and the email on your account, within 30 days of first accepting these Terms. Opting out does not affect any other part of these Terms. 15.6 Class-action and jury-trial waiver. To the fullest extent permitted by law, you and Rivus waive any right to a jury trial and any right to bring or participate in a class, collective, consolidated, or representative action. The arbitrator may not consolidate more than one person's claims or preside over any class or representative proceeding. If this waiver is found unenforceable as to a particular claim, that claim (and only that claim) will proceed in court. 15.7 Forum if arbitration does not apply. If Section 15.3 is found not to apply or a dispute is not subject to arbitration, you and Rivus agree to the exclusive jurisdiction of the state and federal courts located in Travis County, Texas, and you consent to personal jurisdiction there. 15.8 Equitable relief carve-out. Either party may seek injunctive or other equitable relief in a court of competent jurisdiction to protect its intellectual-property rights or to prevent unauthorized access to or misuse of the App, without first using the informal-resolution or arbitration process. 16. Apple App Store Terms (Required) These Terms are between you and Rivus, not Apple, and Apple is not responsible for the App or its content. This Section applies to your use of the App obtained from the Apple App Store, and you acknowledge: • Scope of license. Your license to the App is a non-transferable license to use it on any Apple-branded device you own or control, as permitted by the Apple Media Services / App Store Terms. • Maintenance and support. Rivus, not Apple, is solely responsible for any maintenance and support for the App. Apple has no obligation to provide any maintenance or support. • Warranty. To the extent any warranty is not effectively disclaimed, if the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any); Apple has no other warranty obligation, and any other claims are Rivus's responsibility. • Product and other claims. Rivus, not Apple, is responsible for addressing any claims relating to the App, including product-liability, legal-compliance, and consumer-protection claims, and any third-party claim that the App or your use of it infringes intellectual-property rights. • Legal compliance. You represent that you are not located in a country subject to a U.S. Government embargo or designated as "terrorist-supporting," and that you are not on any U.S. Government list of prohibited or restricted parties. • Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. • To the extent of any conflict between these Terms and Apple's standard licensed-application terms, Apple's minimum terms apply for that conflict. 17. Changes to These Terms We may update these Terms from time to time. We will post the revised Terms with a new "Last Updated" date and, for material changes, notify you in-app or by email. Material changes take effect no earlier than 14 days after posting unless the law or these Terms require sooner. Continued use after the effective date means you accept the updated Terms; if you do not agree, stop using the App and may delete your account. 18. General • Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and Rivus about the App and supersede prior agreements on that subject. • Severability. If any provision is found unenforceable, it will be modified to the minimum extent necessary or severed, and the rest remains in effect. • No waiver. Our failure to enforce a provision is not a waiver of it. • Assignment. You may not assign these Terms; we may assign them in connection with a merger, acquisition, financing, or sale of assets. • Force majeure. We are not liable for any delay or failure to perform caused by events beyond our reasonable control, including acts of God, natural disasters, outages of third-party services or data feeds (such as USGS, NWS, Apple, Supabase, or the AI provider), or network or power failures. • Notices to you may be given in-app or to your account email; notices to us go to support@rivusapp.com. • Copyright. If you believe content in the App infringes your copyright, email support@rivusapp.com with the details required under the Digital Millennium Copyright Act (DMCA), and we will respond appropriately. 19.
