PaxHelios Eval Psy is clinical assessment software for psychologists and mental health professionals. It streamlines psychological evaluations with automated scoring and centralized data management, offering 95 instruments across 38 clinical domains - anxiety, depression, trauma, ADHD, cognitive impairment - including 13 classic validated scales, 61 royalty-free original scales, and 10 interactive neuropsychological tasks (Stroop, N-Back, Flanker, TMT). The platform automates the workflow from intake to report: instant scoring with subscales and severity bands, critical-item alerts, pre-built batteries, longitudinal pre/post comparison, and exportable structured reports. Health data is hosted in France on HDS-certified infrastructure, with AES-256 encryption at rest, GDPR compliance, role-based access, two-factor authentication and audit logs. Assisted synthesis drafts summaries and suggestions: it is a decision-support tool and never replaces the practitioner's clinical judgement.
