Ephemeral, Zero-Knowledge Architecture

PsychDeck operates on an ephemeral, zero-knowledge data model. Patient responses are processed entirely in active memory (RAM) to calculate scores and are instantly routed to the hosting clinician via encrypted WebSockets. We do not use databases, we do not log assessment payloads, and all session data are permanently destroyed when the session ends.

What We Do Not Collect

• Patient names, email addresses, or account credentials — PsychDeck has no user accounts.
• Assessment responses or scores — these exist only in memory during the active session.
• IP addresses — connection rate-limiting uses irreversible SHA-256 hashes; raw IPs are never stored or logged.
• Cookies or tracking identifiers — PsychDeck does not use analytics, advertising, or tracking cookies.

What We Do Process

• Session identifiers — randomized, ephemeral IDs used to route data between the clinician and patient during a live session. These are discarded when the session ends.
• Assessment scores — calculated in the patient's browser using the instrument's published scoring rubric, then transmitted to the clinician via encrypted WebSocket. Scores are never written to disk or logged.

Data Retention

PsychDeck retains zero patient data. There is no database. When a session ends, all associated data — scores, responses, session identifiers — are permanently and irrecoverably destroyed.

Data Subject Rights

Under applicable data protection laws (such as GDPR and CCPA), you have the right to access, correct, or delete your personal data. Because PsychDeck operates on a zero-knowledge architecture and permanently destroys all session data upon completion, we do not hold any personal data that can be accessed, corrected, or deleted after your session ends. If you have questions about your data rights or how your data was processed during a session, you may contact us using the information provided in the Contact section below.

HIPAA Posture

Because PsychDeck does not receive, maintain, or transmit Protected Health Information (PHI) as defined under 45 CFR §160.103, the platform operates outside the scope of HIPAA's covered entity and business associate requirements. The administering clinician is solely responsible for documenting assessment results in their own HIPAA-compliant electronic health record (EHR) system.

Terms of Use

Clinical Instruments

PsychDeck is a digital interface for standardized clinical assessment instruments that are published by their respective authors and organizations. PsychDeck does not develop, modify, or claim ownership of any hosted instrument. All instruments are reproduced in accordance with their respective public domain, open access, or attribution-based license terms. Original citations and publisher attributions are displayed within the application.

Not a Medical Device

PsychDeck is a data display and transit tool. Scores are calculated strictly according to each instrument's published scoring rubric — no proprietary algorithms, clinical decision logic, or diagnostic interpretations are applied. PsychDeck does not diagnose conditions, recommend treatments, or provide clinical advice of any kind.

Clinical Responsibility

PsychDeck is a technical transit layer. The administering clinician assumes all responsibility for selecting appropriate instruments, verifying the accuracy of scores, interpreting results within their clinical context, and securely documenting the data in their own HIPAA-compliant record system.

Intended Use

PsychDeck is intended for use by licensed healthcare professionals in clinical and telehealth settings. It is not intended for self-diagnosis by the general public.
