Privacy Policy

At MVP, we believe your fantasy sports data should remain yours. This Privacy Policy explains how we handle your information when you use the MVP Chrome extension.

1. Data Collection and Usage

MVP is designed as a client-side-first application. We do not collect, store, or sell your personal information.

• Fantasy League Data: When you sync your leagues from Yahoo, ESPN, CBS, or Fantrax, the data (rosters, standings, stats) is fetched directly from those platforms to your browser. This data is never sent to our servers.
• Authentication: We do not see or store your login credentials. MVP uses your existing browser session cookies to securely request data from fantasy platforms on your behalf.
• Projections & Stats: We fetch public fantasy projections and schedule data from a hosted Google Apps Script. These requests are anonymous and do not contain any information about your leagues, teams, or identity.

2. Local Storage

To provide a fast and offline-capable experience, MVP stores the following data locally on your device using chrome.storage and IndexedDB:

• Your synchronized league settings.
• Cached player stats and projections.
• User preferences (e.g., UI theme, column visibility).

You can clear this data at any time by uninstalling the extension or clearing your browser's local storage.

3. Third-Party Services

MVP interacts with third-party fantasy sports platforms:

• Yahoo Sports
• ESPN Fantasy
• CBS Sports
• Fantrax

Your use of these platforms is governed by their respective privacy policies and terms of service.

4. Permissions Justification

• Storage: Used to save your settings and cache data for performance.
• Cookies: Used to maintain your authenticated sessions with fantasy platforms so you don't have to log in manually within the extension.
• Host Permissions: Required to communicate with your fantasy platforms to retrieve and update your league data.

5. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by the "Effective Date" at the top of this page.
