Numerical data only. Hospital-controlled.

ASTA reads LCD display numerics, not patients — no patient imagery is captured, stored, or transmitted, and standard monitoring consent applies. The platform operates under ISO 13485-certified quality management with a DPDP-aligned architecture, encryption in transit and at rest, role-based access control at every layer, and a full audit trail, with deployment posture — data residency, retention, and access — under hospital ownership. A detailed security overview is available on request.
