"RFWIN", "we", "us" means Rewards Fuel LLC, a company registered in Saint Kitts and Nevis, operating the RFWIN service at rfwin.uk.
"You" means any visitor, draw organiser, contestant, or developer using the service or API.
"Service" means the rfwin.uk website, draw engine, API, MCP integration, verification ledger, and all related tools.
"Draw" means a randomised winner-selection event created through the Service, with results stored permanently on the public verification ledger.
You accept these Terms when you visit rfwin.uk, submit a draw, enter a draw, call the API, or otherwise use the Service. If you use the Service on behalf of an organisation, you represent that you have authority to bind that organisation.
You must be at least 18 years old (or the age of majority where you live) and capable of forming a binding contract. You may not use the Service where prohibited by law. We may refuse or terminate access at any time, without liability.
RFWIN is a cryptographic draw tool. Each draw uses a commit–reveal scheme and the drand public randomness beacon to produce a verifiable, unbiased result. Draw results are permanently stored on the public ledger and cannot be altered or deleted after submission.
The Service is provided "as is" and "as available". We do not warrant uninterrupted or error-free operation; that any specific drand round will be available; that results will be accepted by any third-party platform (Instagram, YouTube, etc.); or fitness for any purpose including compliance with sweepstakes, lottery, or contest laws.
All draw data — including masked entrant identifiers, prize details, server seeds, drand values, and winner derivations — is stored permanently in the RFWIN public verification ledger. Once a draw is submitted, it cannot be deleted. Do not submit data you are not authorised to make public in this form. We are not liable for any harm arising from the permanent, public nature of draw records.
By entering a draw you agree to the draw organiser's rules and these Terms. You submit information at your own risk. We are not a sponsor of third-party contests unless we explicitly say so. Email addresses are stored only as one-way SHA-256 hashes and masked display strings — the original email address is not stored.
The free tier of RFWIN is available without payment. Paid features are billed through Rewards Fuel LLC via the Rewards Fuel platform. Fees are non-refundable except where required by mandatory law or explicitly stated at purchase.
You may request a refund within 2 days of initial purchase if you have not materially used paid features. After use, refunds are at our sole discretion. Payment processing may be provided by third parties; their terms apply.
API access is provided subject to fair use. We may rate-limit, suspend, or revoke API access at any time. The HOST_API_KEY is a secret credential — you are responsible for its security. We are not liable for draws created through your key by unauthorised parties.
We own the RFWIN service, branding, and underlying software. You receive a limited, revocable, non-exclusive licence to use the Service while your account is in good standing. You retain ownership of content you submit; you grant us a licence to store, display, and process it to operate the Service and maintain the public verification ledger.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THE ACCURACY OF DRAW RESULTS, THE AVAILABILITY OF THE DRAND BEACON, OR THAT THE SERVICE WILL MEET ANY LEGAL REQUIREMENT IN YOUR JURISDICTION. NO ADVICE OR INFORMATION FROM US CREATES ANY WARRANTY.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, REWARDS FUEL LLC, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AND AFFILIATES SHALL NOT BE LIABLE FOR ANY: INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES; LOSS OF PROFITS, REVENUE, GOODWILL, DATA, ENTRIES, OR BUSINESS OPPORTUNITY; COST OF SUBSTITUTE SERVICES; DATA BREACH, UNAUTHORIZED ACCESS, OR DATA LOSS; DRAW DISPUTES, PRIZE CLAIMS, REGULATORY FINES, OR ENTRANT CLAIMS; OR ANY OTHER DAMAGES ARISING FROM OR RELATED TO THE SERVICE OR THESE TERMS, WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY.
AGGREGATE CAP: OUR TOTAL LIABILITY FOR ALL CLAIMS SHALL NOT EXCEED THE GREATER OF (A) USD $100 OR (B) AMOUNTS YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM.
You agree to defend, indemnify, and hold harmless Rewards Fuel LLC from any claim, loss, liability, damage, cost, or expense (including reasonable attorneys' fees) arising from: (a) your draws, content, or data practices; (b) your violation of these Terms or any law; (c) your violation of third-party rights; or (d) any dispute between you and an entrant or other user.
We may suspend or terminate your access immediately, with or without notice, for any reason. Draw records on the public ledger will persist after termination. We are not liable for termination or data retained under the public ledger policy.
These Terms are governed by the laws of the Federation of Saint Christopher and Nevis, without regard to conflict-of-law principles. You agree that the courts of Saint Kitts and Nevis have exclusive jurisdiction over any dispute.
Class action waiver: You may bring claims only in your individual capacity, not as a plaintiff or class member in any class or representative proceeding, to the extent permitted by law.
