Terms & Conditions

HootFF is a personal analytics tool for fantasy football players. It reads your Sleeper leagues to surface insights, projections, dynasty valuations, and trade intelligence across your leagues. If you link your Sleeper account, HootFF can also make the changes you confirm in it, such as setting a lineup, moving a player to IR, or submitting a waiver claim. HootFF never acts in your Sleeper account without your confirmation.

You must be at least 18 years old (or the age of majority in your jurisdiction) to use HootFF. By using the Service, you confirm that you meet this requirement.

HootFF reads your leagues through Sleeper’s public API, using the username you provide. Reading needs no password and changes nothing.

To act from HootFF, you can link your Sleeper account with a one-time code that Sleeper sends you. HootFF never sees your Sleeper password. The session this creates stays in your browser and is sent only to Sleeper, never to HootFF’s servers. Every change is shown to you first and sent only when you confirm it. You can unlink at any time in Settings, which deletes the session from your browser.

Linking is optional and at your own risk. HootFF is not affiliated with Sleeper, and Sleeper’s terms of service still apply to your account. HootFF makes your changes through the same interface Sleeper’s website uses, which Sleeper can change or limit at any time. You are responsible for the changes you confirm; if a result looks wrong, check your league in Sleeper.

Your browser keeps your Sleeper username so HootFF can load your leagues. If you create a HootFF account, we also save your Sleeper username and Sleeper user ID to that account, so your leagues follow you to any device you sign in on. The Privacy Policy lists everything we store and where. You are responsible for keeping your Sleeper account credentials secure.

You agree to use HootFF only for its intended purpose — personal fantasy football analytics. You must not:

• Attempt to scrape, copy, or reverse-engineer HootFF’s algorithms or scoring models.
• Use the Service to build a competing product.
• Circumvent any rate limits or technical restrictions of the Service or of the APIs it uses.
• Use the Service in any way that violates applicable law.

HootFF relies on third-party data to power its features:

• Sleeper API — league, roster, player, and stats data. Subject to Sleeper’s own terms of service.
• FantasyCalc — public dynasty and redraft market values. Subject to FantasyCalc’s terms of service.

HootFF has no affiliation with Sleeper or FantasyCalc. We are not responsible for the accuracy, availability, or continuity of data provided by these services.

Fantasy football involves inherent uncertainty. All projections, valuations, rankings, and signals generated by HootFF are informational estimates — not guarantees. Data may be delayed, inaccurate, or incomplete. You should always apply your own judgement before acting on any information provided by the Service.

HootFF is not a financial service and does not provide financial, legal, or gambling advice. Do not use HootFF as the sole basis for decisions involving real money.

All analytics models, algorithms, scoring engines, dynasty valuation logic, design systems, and software comprising HootFF are the exclusive intellectual property of HootFF and its creators. Nothing in these Terms grants you any rights to that intellectual property.

Player names, team names, and NFL statistics are the property of their respective owners. HootFF does not claim ownership over this data.

HootFF is provided “as is” and “as available” without warranties of any kind, express or implied — including but not limited to fitness for a particular purpose, merchantability, or uninterrupted availability.

To the maximum extent permitted by applicable law, HootFF and its creators shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service — including but not limited to lost fantasy matchups, trade decisions made using HootFF data, or service interruptions.

You can stop using HootFF at any time, and you can delete your account in Settings.

We may suspend an account if it is used to abuse the Service or if it breaks these Terms.

We may end the Service by giving reasonable notice.

Portuguese law governs these Terms.

Disputes about these Terms go to the courts of Lisbon, without prejudice to any mandatory right you have as a consumer to bring a claim in the courts of the country where you live.

We may update these Terms from time to time. Continued use of HootFF after changes are posted constitutes your acceptance of the revised Terms. The effective date at the top of this page will be updated accordingly.
