Privacy Policy

MFL Core is an independent mobile app operated by [Your Full Legal Name] (“we,” “us”). It gives MyFantasyLeague.com (“MFL”) players and commissioners a native way to view and manage their leagues. This policy explains what information the app handles, why, and what choices you have.

Our commitments

• No ads. MFL Core does not show advertising and does not include advertising SDKs.
• No selling or sharing your personal information. We do not sell your personal information, and we do not share it with third parties for their own marketing.
• No MFL Core account. You sign in with your existing MFL account. We do not keep a user account or profile for you on our servers.
• Your MFL login stays on your device. We do not receive or store your MFL username or password on our servers.

Information the app handles

Your MyFantasyLeague login. To use MFL Core you sign in with your own MFL username and password. Your login is sent from your device directly to MyFantasyLeague.com to authenticate you. The login session information the app needs to keep you signed in is stored on your device only.

Your league data. After you sign in, the app retrieves your leagues, rosters, scores, and transactions directly from MFL's servers so it can display them and let you take actions such as lineup changes, adds, drops, and waiver claims. This data comes from MFL and remains under MFL's control.

Player news and statistics. MFL Core uses a backend service (Supabase) to cache general player news and statistics so the app loads quickly. This is general football information. It is not information about you.

Optional Trade Mediator connection. If you choose to connect The Trade Mediator (see below), the connection information the app needs is stored on your device only. Your Trade Mediator account and any data in it are managed by that service, not by us.

Technical data. Like most online services, the infrastructure providers we use may automatically process technical information such as IP address and request logs when the app or this website contacts them. We use this only to operate and secure the service.

Website analytics. This website uses basic analytics from Vercel to understand aggregate page views. The mobile app does not include analytics or advertising tracking.

How we use information

• To sign you in and display your leagues, rosters, and scores.
• To carry out the actions you choose to take in the app.
• To load cached player news and statistics quickly.
• To power the optional Trade Mediator connection, if you use it.
• To operate, secure, and improve the app and this website.
• To respond to support requests.

Third-party services

• MyFantasyLeague.com. MFL Core connects to MFL using its public developer API. MFL receives your login and requests and handles that data under its own terms and privacy policy. MFL Core is not affiliated with or endorsed by MyFantasyLeague.com.
• Supabase. Our backend provider, used to cache player news and statistics.
• Vercel. Hosts this website and provides its basic analytics.
• The Trade Mediator. A separate, paid platform for AI-assisted trade analysis. It has its own account, authentication, terms, and privacy policy. Connecting it to MFL Core is optional, and you can use the rest of the app without it.
• Apple and Google. The app is distributed through the App Store and Google Play, which handle downloads, payments, and platform-level diagnostics under their own policies.

Data retention and deletion

Because we do not keep an account or profile for you, there is no personal account data on our servers to delete. The cached player news and statistics are general data and are not tied to any person.

Information stored on your device, such as your signed-in MFL session and any Trade Mediator connection, can be removed by signing out of the app or deleting the app. Data held by MyFantasyLeague.com or The Trade Mediator is managed by those services, so contact them directly to access or delete it. If you would like us to confirm what we hold about you, or you have any deletion question, contact us using the details below.

Your rights and choices

You can sign out or delete the app at any time, disconnect The Trade Mediator, and change or revoke your MFL password directly with MyFantasyLeague.com. Because we do not sell or share personal information and do not maintain user profiles, there is generally nothing further for us to disclose or delete, but you are welcome to contact us with any request and we will respond.

Where MFL Core is offered

MFL Core is intended for users in the United States. It is not offered or directed to users in other regions.

Children's privacy

MFL Core is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will delete it.

Changes to this policy

We may update this policy as the app evolves. When we do, we will change the “Last updated” date above. For significant changes, we will make a reasonable effort to let you know.
