All user progress, including level, experience points, streaks, and accuracy, is stored locally on the user’s device using Chrome’s storage API.
BrainBoost does not collect personally identifiable information such as names, email addresses, or location data.
All data is used solely to provide core functionality of the extension, including tracking user progress and improving user experience.
BrainBoost does not sell, trade, or transfer user data to third parties.
Since all data is stored locally on the user’s device, no external servers are used, reducing the risk of data breaches.
