Terms of Service
Last updated: October 11, 2026
Agreement to these terms
These Terms of Service ("Terms") form a binding agreement between you and OneArbitrage, LLC ("we," "us," or "our") governing your access to and use of our public marketing website (including legal pages and the FAQ), and our subscription software in the native iOS and Android mobile apps (including reverse stock split arbitrage ("RSA") on linked U.S. brokerage accounts where we support your broker), and ordering or billing flows we provide (collectively, the "Services"). Our principal place of business is 5900 Balcones Drive # 33202, Austin, TX 78731.
By accessing the Services, creating an account, or clicking to accept these Terms where presented, you agree to these Terms and our Privacy Policy. If you do not agree, do not use the Services.
Not investment, tax, or legal advice
OneArbitrage is subscription software (SaaS). We are not a broker-dealer, investment adviser, or fiduciary. RSA is an automated workflow you can run on brokerage accounts you link and enable for that purpose; it centers on reverse stock split corporate actions and related execution steps. We do not guarantee returns or any particular outcome, and nothing in the Services is personalized investment, tax, or legal advice, or an offer or solicitation to buy or sell securities. You are solely responsible for your investment decisions and for complying with applicable law and your agreements with your broker.
Description of the Services
The Services today include: (a) this marketing website; (b) sign-up and sign-in through our identity provider (for example Amazon Cognito) in our iOS and Android apps; (c) the mobile app where you manage subscription billing (through Stripe and, on iOS, Apple In-App Purchase), referrals where offered, supported U.S. retail brokerage connections, and RSA status and controls for accounts you link. Supported brokers, features, and limits can change. We may modify, suspend, or discontinue all or part of the Services with reasonable notice where practicable; we may also perform maintenance that temporarily affects availability.
Mobile apps are distributed through the Apple App Store and Google Play (or other channels we designate). Your download and use of the app may also be subject to the applicable store's terms. If there is a conflict between these Terms and mandatory store terms for billing or distribution, the store terms govern only to the extent required for that transaction.
Eligibility
You must be at least the age of majority where you live, have the legal capacity to open and trade through a supported U.S. retail brokerage account, and have the authority to agree to these Terms on your own behalf (or on behalf of an entity you represent). The Services are intended for users in the United States and other regions we expressly support in the product. You may not use the Services if you are subject to sanctions, located in a jurisdiction where use would violate law, or prohibited by your broker from granting the access you provide to us. The Services are not directed to children under 13, and you may not use the Services if you are under 13.
Automation, orders, and your brokerage activity
When you link and enable RSA on an account, you authorize our software to initiate brokerage orders and related steps through that linked session according to the product's configured workflow (including screening and timing rules we apply for reverse stock split corporate actions). You remain responsible for your broker relationship, account settings, and compliance with broker, exchange, and applicable law.
The workflow is built around documented assumptions (for example, how many shares or positions the automation expects for a given signal). If you buy, sell, or otherwise change positions manually in the same account or symbols outside what the Services model, outcomes may differ from what the automation assumes. You are responsible for those manual actions and for reviewing activity in your broker's apps and statements.
Accounts and authentication
You may need to create an account to use certain features. We use single sign-on through an identity provider (for example, Amazon Cognito Hosted UI) with industry-standard flows in our mobile apps (where OneArbitrage sign-in opens in your device's system or in-app browser). You are responsible for safeguarding your credentials, enabling multi-factor authentication when offered, and for all activity under your account. Notify us promptly if you suspect unauthorized access. You may not share account access in a way that violates these Terms or your broker's rules.
When you connect or refresh a supported brokerage (for example Robinhood) in our iOS or Android app, we may show your broker's login pages in an in-app browser (an embedded WebView) rather than the system browser. After you sign in, the app reads session tokens your broker stores in that browser (including a refresh token) and sends them to our servers over HTTPS so RSA can keep running on accounts you enable. We do not ask you to email your brokerage password, and we do not store that password on OneArbitrage. In some mobile fallback flows, reconnect uses a hosted page on our site in your system or in-app browser.
Where the Services support linking brokerage accounts, we link at most three distinct brokerage account identifiers per customer account. You must not try to circumvent that limit (for example by creating multiple customer accounts, manipulating onboarding flows, or similar). If you need a different set of linked account identifiers than we currently have on file, contact us; self-serve removal of a linked identifier may not be available. Restrictions, suspensions, or other actions your broker takes in response to your activity, including activity that violates your broker's terms or policies, are between you and your broker; to the extent permitted by law, we are not liable for those broker actions.
Acceptable use
You agree not to:
- Violate law or third-party rights;
- Interfere with or disrupt the Services, networks, or security (including probing, scanning, or testing without authorization);
- Attempt to access data or accounts you are not authorized to access, or reverse engineer the Services except where applicable law permits;
- Use the Services to transmit malware, spam, or deceptive content, or to automate abusive use of the Services;
- Misrepresent your identity or affiliation, or use the Services to manipulate markets or violate exchange or broker rules.
Third-party services
The Services rely on third parties such as identity providers, cloud infrastructure, Stripe for subscription checkout and recurring billing, Apple for In-App Purchase on iOS, app store platforms (Apple and Google for mobile distribution), analytics and advertising partners we use to measure product and campaign performance (such as Meta), your brokerage, and other processors we use to operate the product. Those services have their own terms and privacy practices; your use of them is between you and the third party. We are not responsible for third-party services we do not control.
Brokerage operational funds
You may link more than one brokerage account where the product supports it (for example, up to three distinct accounts at a supported broker). Where you make or are asked to make a deposit of thirty U.S. dollars (US $30) to each linked brokerage account for use with the Services, OneArbitrage, LLC will not use more than that amount of your funds held at the broker in connection with the Services for that account; for example, if you maintain a larger balance in the same account, we do not target or rely on the portion above that US $30 for our software-driven workflow unless you give us separate written authorization or the product clearly states otherwise.
For purposes of this section, "use" means brokerage orders, transfers, or similar actions that the Services initiate or instruct through your linked account. It does not include amounts you pay us outside your broker (such as subscription fees on a card or bank account), fees or charges imposed by your broker, taxes, corporate actions, interest, or activity you perform manually in your broker's apps or websites outside the Services. Nothing in this section changes your agreements with your broker or applicable law.
Fees and billing
Paid access is by subscription unless we offer something different in the product. Pricing, taxes, and renewal terms are shown at checkout and in the app billing area. Your first successful trade on a linked account is free. After that, membership is $5 per week (or the equivalent price shown at checkout or in the App Store). No payment card is required to start. On Android (and optional US iOS checkout through Stripe), billing runs through Stripe. Unless you cancel, membership continues at the shown weekly rate and renews automatically each billing period until you cancel. Cancel anytime from Settings in the app or the Stripe customer portal we link you to.
On the iOS app, the primary paid path is an auto-renewable Apple In-App Purchase (for example OneArbitrage Weekly or the product name shown in the App Store). Apple charges your Apple ID at the localized App Store price shown at purchase, which may differ from the Stripe price. When available on the US App Store, you may instead subscribe through Stripe in your system browser. Payment card details for Apple purchases stay with Apple; we receive subscription status and transaction identifiers needed to unlock the product. Apple subscriptions renew until you turn off auto-renew in your Apple ID account settings. Stripe subscriptions are managed in the app or Stripe customer portal. Deleting your OneArbitrage account stops Stripe billing when deletion completes; it does not cancel an App Store subscription. If you subscribed through Apple, turn off auto-renew in your Apple ID subscription settings to stop future charges. If you do not pay amounts when due, we may suspend or terminate access to paid features.
Except where required by law or expressly stated at checkout, subscription fees are non-refundable. If you initiate a chargeback or payment dispute without contacting us first, we may suspend your account while we investigate. We may change subscription prices for future periods with reasonable notice (for example, by email, in-app notice, or at renewal); continued use after the effective date constitutes acceptance of the new price for subsequent billing periods where permitted by law.
Referral program
If we offer a referral program, participation is optional. Rates, eligibility, qualification (including whether renewals count), and payout timing follow the rules shown in the app and depend on paid invoices, program rules, Stripe processing, and cancellations. Referral rewards are not tax guidance; use your own tax advisor. How invite codes are captured on the marketing site or through mobile invite deep links is described in our Privacy Policy.
Intellectual property
We and our licensors own the Services, including software, branding, text, graphics, and other content (excluding your content and third-party materials). Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Services for your personal or internal business use as permitted by the product. You may not copy, modify, distribute, sell, or lease our proprietary materials except as allowed by law or with our written consent.
Investment and trading risks
Securities trading and corporate-action strategies involve substantial risk, including the possible loss of your entire investment. Prices can move quickly; trading can be halted; issuers and brokers can delay or change processing; and tax treatment can be complex (including for retirement accounts). Past performance or examples in our marketing or product are not guarantees of future results. Review the in-app legal and disclosures pages and consult qualified professionals for investment, tax, and legal questions.
Disclaimers
THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS, OR THAT ANY INFORMATION WILL BE ACCURATE OR COMPLETE.
Third-party advertising and communications
Content about OneArbitrage or the Services may appear in places we do not control, including paid search, display or social advertising, blogs, forums, or influencer posts. That content may not be from or approved by OneArbitrage, LLC, may be outdated or inaccurate, and may include claims we would not make, such as guaranteed profits, minimum monthly returns, or similar performance promises. You should not rely on those materials; what we stand behind is what we publish on our own websites and applications and what these Terms say, together with the "Not investment, tax, or legal advice" section above.
To the maximum extent permitted by law, OneArbitrage, LLC is not responsible for any loss, reliance, or harm arising from unauthorized, false, or misleading third-party promotions or statements about us or the Services, including where they exaggerate benefits or omit material risks.
Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER OneArbitrage, LLC NOR ITS SUPPLIERS OR AFFILIATES WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR REVENUE. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES IS LIMITED TO THE GREATER OF THE AMOUNTS YOU PAID US FOR THE SERVICES IN THE TWELVE (12) MONTHS BEFORE THE CLAIM OR ONE HUNDRED U.S. DOLLARS (US $100), EXCEPT WHERE LIABILITY CANNOT BE LIMITED BY LAW. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS; IN THOSE CASES OUR LIABILITY IS LIMITED TO THE FULLEST EXTENT PERMITTED.
Indemnity
You will defend, indemnify, and hold harmless OneArbitrage, LLC and its affiliates, officers, directors, employees, and agents from any claims, damages, losses, or expenses (including reasonable attorneys' fees) arising out of your use of the Services, your violation of these Terms, or your violation of law or third-party rights.
Suspension and termination
We may suspend or terminate your access to the Services if you materially breach these Terms, if we must do so to comply with law, or to protect security or other users. You may stop using the Services at any time. You may close your OneArbitrage account and request deletion of associated product data by opening the app, going to Settings, and using Delete account (as described in our Privacy Policy), or by contacting us on our Contact page (including support@onearbitrage.com). Provisions that by their nature should survive (including intellectual property, disclaimers, limitation of liability, indemnity, and governing law) will survive termination.
If you create an account, never subscribe, and do not use the Services, we may close that account after two email notices that state the deletion date. Signing in before that date keeps the account. We leave the account in place when you have ever subscribed, when you still have an open position, when you already completed the free first trade, or when a referral payout is still unfinished. Closing the account removes your OneArbitrage login and personal product data. Your brokerage account stays open. If you had linked Robinhood, a later OneArbitrage account that links the same Robinhood identity is treated as if the free first trade was already used. Referral and reward amounts we must keep stay on file after we clear your email. Details are in our Privacy Policy.
Assignment and force majeure
You may not assign or transfer these Terms or your account without our prior written consent. We may assign these Terms in connection with a merger, acquisition, corporate reorganization, or sale of assets. We are not liable for delay or failure to perform due to events beyond our reasonable control (including internet or broker outages, acts of government, labor disputes, or natural disasters).
Governing law and venue
These Terms are governed by the laws of the State of Texas, without regard to conflict-of-law rules, except where preempted by U.S. federal law. You and we agree that the state and federal courts located in Travis County, Texas, USA will have exclusive jurisdiction for disputes arising out of or relating to these Terms or the Services, subject to mandatory consumer protections in your jurisdiction where applicable.
Changes to these Terms
We may update these Terms from time to time. We will post the updated Terms on our website and revise the "Last updated" date. If changes are material, we may provide additional notice (for example, by email or in-app notice) where required. Continued use of the Services after the effective date constitutes acceptance of the updated Terms, except where your explicit consent is required by law.
