We may process basic account-related information provided by Yahoo (such as user ID and team ownership data) in order to provide core functionality.

c) Website Content

The extension reads data from Yahoo Fantasy Sports pages (such as player data, matchups, and roster information) to enable features like lineup optimization and transaction scheduling.

d) User Activity

We collect data related to how you interact with the extension (such as scheduled actions, settings, and feature usage) to ensure proper functionality.

e) Location Data (Limited)

We may process approximate location data such as IP address as part of standard communication with backend services. This is not used to track your physical location.
