No microphone, audio recording, login, or file upload. Tempo settings remain in your browser. We store a random browser ID for 30 days, an assigned first-practice instruction variant and its first 30-minute playback results, campaign label, homepage revision, whether the browser ID was newly created, and page, guide, start-button visibility, playback attempts, successes, interruptions and failures, 5, 10, 15 and 30-second playback, Google Play link clicks, practice-note views and resource-link/print-click events to measure this experiment. The experiment database stores no names, emails, or full IP addresses. Old events are removed on a new event or report request. Browser IDs are not verified unique people; clicks are not purchases. Earlier pre-order details stay with PayPal and are used only for delivery, support and refunds. Questions: Ok Er on Peerlist.
