MindPulse

MindPulse is an invitation-only, IRB-approved University of Wisconsin–Madison research app for consented study participants. You can access the app only if you are enrolled in an active research study and have a valid enrollment code from the research team. The app's core function is participant-controlled collection of encrypted smartphone-use and research-context data. When a participant turns Data Collection on and separately taps Start Location Collection, MindPulse collects precise GPS location for research context, including while the app is closed or not in use. A persistent "MindPulse location collection is active" notification remains visible for the entire location session. Participants can stop all collection from the notification or by turning Data Collection off in the app. Location is the app's only foreground-service use; encrypted uploads run as scheduled background work. Accessibility API disclosure: MindPulse uses Android AccessibilityService API to capture encrypted screenshots for approved research data collection.

SECURITY: All data is encrypted on device and transmitted securely to authorized UW-Madison research systems. Participation is voluntary, and participants can stop or disable capture at any time. Privacy and participant rights are described in the app privacy policy.
