What data does Neurokeys collect?

Your brain health scores come from two sources: - Typing patterns captured by the Neurokeys keyboard -- timing, rhythm, and corrections. Never the actual text you type. - Optional activity data (if you grant access): steps and flights climbed from HealthKit (iPhone) or Google Fit (Android). This adds context to clinical reports but is not required for your scores to work. We do not collect sleep data, heart rate, or other health metrics.
