Privacy Policy

Fantasy Football Connector for Muse. Effective 2026-09-27.

What this connector does

It reads your fantasy football leagues on Sleeper, ESPN, and Yahoo so Muse can show rosters, matchups, standings, transactions, and advice. It is read only. It cannot change lineups, submit waiver claims, or propose or accept trades.

Data we handle

• Public leagues: league id, season, week, and team id you provide, plus the public league data returned by the provider. No account or login needed.
• Private leagues: ESPN swid / espn_s2 cookies or a Yahoo OAuth access token. These arrive per request from Muse's Secure Credentials Store. They are used only to call the provider for that request, never written to disk, never logged, and never sent anywhere else.
• Operational: request method, path, status code, and timing for reliability. No request or response bodies are logged.

What we do not do

• No persistent storage of league data, credentials, or tokens on the server.
• No sale or sharing of your data with advertisers or data brokers.
• No tracking cookies. No analytics SDKs.

Subscription status

Tier checks (Free / Pro / Commissioner) read a subject identifier from the request and compare it against a server-side list. No payment details are handled by this connector; checkout happens on the payment provider's page.

Retention

There is nothing to retain: the connector is stateless. In-memory caches (Sleeper player map, rate limiter) live only in the running process and are discarded on restart.
