These Terms of Service ("Terms") are an agreement between you and RotoCore ("RotoCore", "we", "us") covering your use of the website at https://www.rotocore.com and the tools it provides (the "Service"). By creating an account or using the Service you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.
1. What RotoCore is (and isn't)
RotoCore is a lineup-building tool for daily fantasy football. It combines publicly available salary, projection, injury and betting-odds data and lets you generate and edit lineups you can export as a CSV file. RotoCore does not run contests, accept entries or wagers, hold funds, or pay out prizes. Any contest you enter is between you and the contest operator, under that operator's rules.
RotoCore is not affiliated with, endorsed by, or sponsored by DraftKings Inc. "DraftKings" is a trademark of DraftKings Inc. and is used only to describe the contest formats the tool supports.
2. Eligibility
You must be at least 18 years old to use the Service. Some jurisdictions set a higher minimum age for daily fantasy contests; you are responsible for knowing and following the laws that apply to you, including whether daily fantasy contests are permitted where you live. Do not use the Service if doing so is unlawful in your location.
3. Your account
You need an account with a verified email address to use the optimizer. Keep your password confidential; you are responsible for activity under your account. One person may hold one account, and accounts may not be shared, sold or transferred. Tell us at support@rotocore.com right away if you believe your account has been accessed without permission.
4. Free tier and Season Pass
The Free tier lets you build a limited number of lineups per run with the core settings. The Season Pass is a one-time purchase (currently $39.95) that unlocks the full lineup count, advanced settings and CSV export for the 2026 NFL Season. Season Pass access ends on February 15, 2027 and does not renew or recur; there is nothing to cancel. Prices are shown in US dollars and may change for future seasons. Payments are processed by Stripe; we never see or store your full card number. Refunds are governed by our Refund Policy.
5. Acceptable use
You agree not to: (a) access the Service by any automated means, or scrape, crawl or bulk-download its data; (b) resell, redistribute or make the Service or its data available to third parties; (c) reverse engineer, probe or interfere with the Service or its security; (d) use the Service to violate any law or the rules of any contest operator; or (e) submit requests designed to overload the optimizer. We may rate-limit, suspend or terminate accounts that break these rules.
6. No guarantee of results
Projections, odds and optimizer output are estimates built from third-party data that may be incomplete, delayed or wrong. Player news changes constantly. RotoCore makes no promise that any lineup will win, cash, or perform in any way. Daily fantasy contests involve risk of financial loss, and every entry decision is yours alone. Nothing on the Service is financial, gambling or investment advice.
7. Third-party data and services
The Service relies on data from contest operators, sportsbooks and sports-news providers, and on services such as Stripe and Resend. We do not control those parties and are not responsible for their accuracy, availability or terms. If a data source changes or becomes unavailable, features that depend on it may be degraded or removed.
8. Intellectual property
The Service, its design, code and content are owned by RotoCore or its licensors and protected by copyright and other laws. You may use the lineups you generate for your own contest entries. You may not copy, modify or create derivative works of the Service itself. Team and player names and marks belong to their respective owners.
9. Availability and changes
We work to keep the Service available but it is provided "as is" and may be interrupted for maintenance, data-source outages or reasons outside our control, including on contest days. We may change or discontinue features at any time. If we discontinue the Service entirely during a season for which you hold a Season Pass, we will refund a pro-rated portion of your purchase.
10. Termination
You may close your account at any time from your profile page. We may suspend or terminate your access if you breach these Terms, if we are required to by law, or if your payment is disputed or reversed. Sections 6, 8, 11 and 12 survive termination.
11. Disclaimer of warranties
TO THE FULLEST EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT.
12. Limitation of liability
TO THE FULLEST EXTENT PERMITTED BY LAW, ROTOCORE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY LOST PROFITS, LOST CONTEST ENTRIES OR LOST DATA, ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE IS LIMITED TO THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE. Some jurisdictions do not allow these limitations, so they may not fully apply to you.
13. Indemnity
You agree to indemnify RotoCore against claims, losses and expenses (including reasonable legal fees) arising from your breach of these Terms or your use of the Service in violation of any law or third-party right.
14. Governing law and disputes
These Terms are governed by the laws of the State of California, United States, without regard to conflict-of-law rules. Any dispute will be brought in the state or federal courts located in San Luis Obispo County, California, and you consent to their jurisdiction. Before filing a claim, you agree to contact us at support@rotocore.com and give us 30 days to try to resolve it informally.
15. Changes to these Terms
We may update these Terms from time to time. When we make a material change we will update the effective date above and, for changes that affect paid features, notify you by email. Continuing to use the Service after a change means you accept the new Terms.
