Educators retain sole physical custody and control of all classroom data, ensuring compliance with FERPA, COPPA, and international data privacy regulations by design.

During any free promotional period, beta release, or complimentary trial tier, the Service is provided strictly "AS-IS" and "AS-AVAILABLE" without warranties of any kind, express or implied. Clase Arena LLC does not guarantee continuous uptime, data preservation, or uninterrupted availability, and disclaims all liability for classroom scheduling or instructional disruption.
