RosterRadar Privacy Policy

Effective date: April 17, 2026

RosterRadar ("RosterRadar," "we," "our," or "us") provides a Chrome extension that helps users follow live MLB games based on the relevance of those games to the user's Yahoo Fantasy Baseball matchup.

This Privacy Policy explains what information we collect, how we use it, and how we handle it when you use the RosterRadar Chrome extension and related services.

1. Information We Collect

If you choose to connect your Yahoo Fantasy Baseball account, RosterRadar accesses information needed to provide the extension's functionality, including your Yahoo Fantasy Baseball leagues and teams, your selected fantasy team and matchup, roster and player performance information, and Yahoo account identifiers needed to support sign-in and account connection.

RosterRadar also retrieves public MLB game data needed to rank live games by fantasy relevance, including scores, inning state, runners on base, outs, balls, strikes, player status, and game identifiers.

To preserve setup and personalization across sessions, RosterRadar stores certain information locally in your browser, including your selected fantasy team, feed URLs, scoreboard delay settings, favorites, Auto Tune preferences, onboarding state, cached entitlement state, and Yahoo authentication tokens needed to keep your Yahoo connection active.

RosterRadar may also send limited account-related information to our backend service to verify extension access, provide entitlement or account state, and deliver update notices or account-related messages.

RosterRadar uses Google Analytics to collect limited usage and performance data, such as extension views and interactions, settings changes, Auto Tune actions, selected feature usage, basic feed context, a persistent analytics client identifier, and a Yahoo-linked subject identifier when available.

2. How We Use Information

• Authenticate you with Yahoo and connect your Yahoo Fantasy Baseball team
• Determine which live MLB games are most relevant to your fantasy matchup
• Display game and player context in the extension
• Support Auto Tune and related feed-switching features
• Save your preferences and settings
• Verify access and account status
• Improve product reliability, performance, and user experience
• Communicate extension-related status such as update notices or account messages

3. How We Share Information

We do not sell personal information.

We may transmit or share data only as needed to operate the extension, including with Yahoo for sign-in and fantasy sports data, MLB and the MLB Stats API for live public game data, Google Analytics for limited analytics and product performance measurement, and RosterRadar backend services for access verification, entitlement state, and extension messaging.

We do not use user data for advertising, creditworthiness, lending, or unrelated purposes.

4. Website and Page Access

RosterRadar interacts with supported MLB.com and MLB.TV pages so it can recognize game feeds, present in-page controls, and help manage the user's selected viewing tab. RosterRadar is designed to operate only in connection with its MLB viewing functionality and does not monitor unrelated browsing activity for unrelated purposes.

5. Data Retention

Data stored locally in the extension remains in your browser until it is changed, cleared, or removed by uninstalling the extension or disconnecting relevant services. Third-party services such as Yahoo, Google Analytics, and our backend may retain data according to their own retention practices and policies.

6. Data Security

We take reasonable steps to protect information used by RosterRadar. However, no method of electronic transmission or storage is completely secure, and we cannot guarantee absolute security.

7. Your Choices

• Disconnect your Yahoo account from the extension
• Change or remove local settings stored by the extension
• Uninstall the extension at any time
• Stop using RosterRadar at any time

8. Children's Privacy

RosterRadar is not intended for children under 13, and we do not knowingly collect personal information from children under 13.

9. Third-Party Services

RosterRadar relies on third-party services, including Yahoo, MLB, and Google Analytics. Their handling of data is governed by their own privacy policies and terms.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the effective date above. Continued use of RosterRadar after changes become effective constitutes acceptance of the updated policy.
