Terms of Service
Effective July 24, 2026
These Terms are an agreement between you and Fantasy FLU LLC, a New York limited liability company (“FLU,” “we,” “us”), and govern your use of FLU — the Fantasy League Utils service at fantasyflu.com, including the app, the API that serves it, and FLU Pro paid features (together, the “Service”). By using the Service you agree to these Terms and to our Privacy Policy. If you don’t agree, don’t use the Service.
1. What FLU is (and isn’t)
FLU is a read-only analysis tool for fantasy leagues hosted on Sleeper. It reads your league’s public data through the Sleeper API and builds views on top of it — trade histories, draft orders, keeper and contract tracking, records, and similar analysis. FLU cannot modify your Sleeper league, rosters, or account.
FLU is an independent product. It is not affiliated with, endorsed by, or sponsored by Sleeper, and “Sleeper” and related marks belong to their owner. FLU depends on the Sleeper API to function; if Sleeper changes or discontinues its API, parts or all of the Service may stop working.
FLU is an entertainment and analysis tool. It is not a gambling, wagering, or betting service, and nothing in it is advice about wagering. Data and projections may contain errors — verify anything that matters against your league’s own records.
2. Eligibility
You must be at least 13 years old to use the Service, and at least 18 (or the age of majority where you live) to purchase a subscription. If you use the Service on behalf of a league, you’re responsible for having whatever authority your league expects you to have — FLU’s commissioner and editor roles mirror your league’s own structure.
3. Your account
You sign in with your email address (via a one-time code) or a passkey. Keep access to your email and devices secure — anyone who controls them can access your account. You’re responsible for activity under your account. You can sign out of all devices, or delete your account entirely, from settings.
Sleeper identity linking. You may link one Sleeper identity to your FLU account, and each Sleeper identity can be claimed by only one FLU account — the first account to verify a claim holds it. Linking tells FLU which team is yours; it does not give FLU control of your Sleeper account. If you believe someone has wrongly claimed your Sleeper identity, contact us and we’ll investigate and resolve it.
4. The free service
FLU’s core analysis tools are free to use. The free tier is not a time-limited trial. We’re always improving the Service, and we may change, add, or retire features (free or paid) over time; if a change materially reduces something you’ve paid for, §6 (refunds) applies.
5. FLU Pro subscriptions
FLU Pro is an optional paid upgrade purchased per league, per year. One Pro subscription covers a single league (its full dynasty chain) for all of that league’s members — any member can buy it, and the payer plus the league’s commissioners get access to Pro editing features.
Billing and auto-renewal. Pro is billed annually through our payment processor, Stripe, at the price shown at checkout plus any applicable tax. Your subscription renews automatically each year, and your payment method is charged at each renewal, until you cancel. By subscribing, you authorize these recurring charges.
Cancellation. The payer can cancel at any time, online, through the billing portal linked from the league’s settings; anyone can also ask us to cancel by contacting us. Cancellation takes effect at the end of the current paid year — you keep Pro until the period you paid for runs out, and you won’t be charged again. We don’t hard-shut features the moment a subscription lapses; there is a short grace period before Pro features revert to the free tier.
Founding pricing. If you subscribe at a founding price, that price is locked in for the life of your subscription: it will never increase at any renewal, for as long as your subscription remains continuously active. If a founding subscription is cancelled or lapses, the price lock ends with it, and any new subscription is at the then-current list price.
Price changes. We may change subscription prices. Price changes take effect at your next renewal, and we’ll notify the payer by email at least 30 days before a renewal at a higher price, so there’s time to cancel first.
Renewal reminders. For yearly subscriptions we (or Stripe on our behalf) will send the payer a reminder before renewal where the law requires it — and as our default practice regardless.
6. Refunds
All payments are final and non-refundable, and partial subscription periods are not prorated, except where applicable law requires a refund. We may make exceptions in individual cases (for example, an accidental duplicate purchase), but any such exception is at our sole discretion and doesn’t obligate us to make another. If something’s broken, tell us — we’d rather fix the problem than argue about it.
7. League content and roles
Commissioners and editors can enter keeper values, contract settings, and notes for their league. You keep ownership of what you write; you grant FLU a non-exclusive, worldwide, royalty-free license to host, store, display, and back up that content as needed to run the Service, for as long as the league’s record exists. League content is part of the league’s shared record: it stays with the league even if the author leaves FLU, with authorship disconnected.
You’re responsible for what you enter. Don’t post anything unlawful, abusive, or infringing; we may remove content that violates these Terms. Disputes about what a commissioner entered are league business — FLU provides the tools, your league governs itself.
8. Acceptable use
Don’t misuse the Service. In particular, don’t: attempt to access accounts, leagues, or data you’re not authorized to see; probe, disable, or interfere with the Service or its security; scrape or bulk-harvest the Service beyond normal use (we enforce rate limits); resell or white-label the Service without our written agreement; use the Service to violate Sleeper’s terms; or misrepresent your identity or league role. We may suspend or terminate accounts that violate these Terms.
9. Intellectual property
The Service — its code, design, and the analysis views it produces — belongs to FLU and its licensors. League data sourced from Sleeper belongs to whoever owned it before FLU read it; we claim no ownership over your league’s underlying data or your content. If you send us feedback or ideas, we can use them without obligation to you.
10. Third-party services
The Service depends on third parties we don’t control — the Sleeper API for league data, Stripe for payments, and infrastructure providers for hosting and delivery. Your use of Stripe’s checkout is also subject to Stripe’s terms. We are not responsible for third-party services, and outages or changes on their side may affect the Service.
11. Disclaimers
The Service is provided “as is” and “as available,” without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty that the Service will be uninterrupted, error-free, or that its data will be accurate or complete. Fantasy analysis involves derived data from a third-party API; numbers can be wrong, late, or incomplete. Some jurisdictions don’t allow certain warranty disclaimers, so parts of this section may not apply to you.
12. Limitation of liability
To the fullest extent permitted by law: FLU will not be liable for indirect, incidental, special, consequential, or punitive damages, or lost profits, data, or goodwill; and FLU’s total liability for all claims relating to the Service is limited to the greater of (a) the amounts you paid FLU in the 12 months before the claim arose, or (b) fifty U.S. dollars ($50). Some jurisdictions don’t allow these limits, so they may not fully apply to you. Nothing in these Terms limits liability that can’t lawfully be limited.
Indemnity. You’ll indemnify FLU against third-party claims arising from your content or your violation of these Terms, to the extent caused by you.
13. Disputes, governing law, and arbitration
Talk to us first. Before filing any claim, email us at [email protected] with a description of the dispute. We’ll try to resolve it informally within 30 days; most things should never need more than this.
Governing law. These Terms are governed by the laws of the State of New York, without regard to conflict-of-laws rules.
Arbitration. If we can’t resolve a dispute informally, you and FLU agree to resolve it by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court. The arbitration will be conducted in New York or remotely at your election, and judgment on the award may be entered in any court with jurisdiction.
Exceptions. Either party may bring an individual claim in small-claims court, and either party may seek injunctive relief in court for infringement or misuse of intellectual property or unauthorized access to the Service.
Class-action waiver. Disputes will be resolved only on an individual basis. Neither you nor FLU may participate in a class action, class arbitration, or representative proceeding. If this waiver is found unenforceable for a particular claim, that claim (and only that claim) proceeds in court, not arbitration.
Opt-out. You may opt out of this arbitration agreement by emailing us within 30 days of first accepting these Terms, stating your account email and that you opt out of arbitration. Opting out doesn’t affect any other part of these Terms.
Venue. For anything proceeding in court, you and FLU consent to the exclusive jurisdiction and venue of the state and federal courts located in New York, New York.
14. Termination
You can stop using FLU or delete your account at any time. We may suspend or terminate your access if you violate these Terms, if the law requires it, or if we discontinue the Service; if we terminate a paid subscription without cause before its period ends, we’ll refund the unused portion. Sections that by their nature should survive termination (including §§6, 7 licenses already granted, 9, and 11–13) survive.
15. Changes to these Terms
We may update these Terms. For material changes we’ll give notice — in the app, by email to account holders, or both — before the changes take effect. Continued use of the Service after the effective date means the updated Terms apply. If you don’t agree to a change, stop using the Service and, for paid subscriptions, cancel before your next renewal.
16. General
These Terms (plus the Privacy Policy and any checkout terms) are the entire agreement between you and FLU about the Service. If a provision is found unenforceable, the rest remain in effect. Our failure to enforce a provision isn’t a waiver. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of the business. Notices to you may be given in the app or by email to your account address; notices to us go to [email protected].
