SEN-related data is: • Provided voluntarily by parents; • Used solely to assist centres and coaches where possible; • Not verified, certified, or guaranteed by ClassZ. "SEN-friendly" tags are self-declared by centres and do not constitute endorsement or assurance of suitability.

ClassZ does not use such photos or media for marketing, advertising, or promotional purposes unless separate consent is obtained. Photos and media are visible only to authorised users (such as parents or guardians of enrolled students) and are used solely for class-related documentation and feedback. Parents may request the removal of specific photos or media by contacting customer support. Requests will be reviewed and handled in accordance with applicable laws and operational requirements.
