Cross-Platform User Telemetry and Longitudinal Interaction Metrics in Cloud-Based Digital Interventions (2014-2025)

This dataset presents longitudinal user telemetry (N=1,355) from a non-guided digital relaxation intervention hosted on a Learning Management System (LMS) and its corresponding open-access mirror on YouTube. The data spans an 11-year observation period (May 2014 – Dec 2025). The intervention follows the standardized curriculum of the book "El arte de la relajación", progressing through theoretical foundations, somatic regulation, autonomic control, and mindful attention. This structure allows for a cross-platform comparison between structured learning (LMS) and algorithmic consumption (YouTube). The dataset includes enrollment costs, progression logic, dropout points, and granular video retention metrics, offering real-world evidence on user adherence and the "instrumental use" of digital health tools.
