Privacy Policy

Fantasy League History lets you visualize your Yahoo Fantasy Basketball league's history — standings, head-to-head records, and all-time stats. To load your league, you sign in with your Yahoo account so we can read your league data on your behalf.

We request read-only access to your Yahoo Fantasy Sports data, specifically:

• League standings and matchup results
• Team names and manager identifiers
• Historical season data for leagues you've participated in

We do not access your Yahoo email, personal profile, contacts, or any data outside of Fantasy Sports.

Session tokens — When you sign in with Yahoo, your OAuth access token is encrypted using AES-256 and stored in a secure, HTTP-only browser cookie. It is never written to a database or logged.

League data — Your league history is temporarily cached on the server to avoid re-fetching it on every visit. This cache is stored in ephemeral server memory and resets automatically every few hours. It is never stored in a permanent database.

No account is created. We do not store your name, email address, or any personally identifiable information.

Yahoo— League data is fetched from the Yahoo Fantasy Sports API under your authorization. Yahoo's own privacy policy applies to your Yahoo account.

Vercel — This app is hosted on Vercel. Vercel collects standard server access logs and anonymized page view analytics. See Vercel's privacy policy.

We use a single HTTP-only cookie to store your encrypted Yahoo session token. This cookie is required for the app to function when you sign in. It expires after 30 days or when you clear your browser cookies.

We do not use advertising cookies or third-party tracking cookies.

You can revoke this app's access to your Yahoo account at any time from your Yahoo account security settings. Clearing your browser cookies will also remove your local session.
