On-Device Privacy Technology

The therapy AI that neversees your clients' data.

On-device PHI redaction. The cloud only receives de-identified transcripts. Most platforms don't work this way.

I've been feeling much better lately. My mother, Sarah Mitchell, noticed I've been sleeping through the night. We moved to 142 Oak Street last month and the new environment really helps. You can reach me at (555) 012-3456 if you need to reschedule.

Zero PHI · Safe for cloud processing
The Risk

Most AI platforms upload raw session recordings to their servers.

Think about what's in a therapy session. Names. Diagnoses. Trauma disclosures. Relationship details. Addresses. Dates of birth. Most AI platforms send all of this to their cloud for processing. One misconfiguration, one breach, and it's exposed.

How Mediyn Works

On-device redaction.
Not a server-side filter.

Record

Audio encrypted on your device before anything else happens.

Redact

Names, addresses, and identifiers stripped locally on-device.

Process

Clean, de-identified data processed by AI. Nothing else.

Raw audio never leaves your device.

AI Clinical Summary
Processing...

Client reports significant improvement in sleep quality since medication adjustment last session. Describes reduced frequency of intrusive thoughts, particularly around work-related triggers.

Affect notably brighter — more engaged, sustained eye contact. PHQ-9 score decreased from 18 to 14, now in the moderate range. Client demonstrated strong recall of CBT techniques from previous session.

Current treatment plan is progressing well. Recommend continuing medication at current dose. Assign cognitive restructuring worksheet to build on the thought record work.

Key Insights
Sleep quality improving — 3rd consecutive session
PHQ-9 trending down: 21 → 18 → 14 over 6 weeks
Increased work stress mentioned — monitor next session
Strong CBT technique recall — reinforce with worksheet
Less Admin, More Therapy

Stop spending your evenings catching up on notes.

On-device privacy doesn't mean less capability. Mediyn's AI generates complete clinical documentation the moment your session ends — so you can be fully present with clients and leave on time.

AI clinical notes in your format — SOAP, DAP, BIRP, or custom
Key insights and clinical red flags surfaced automatically
Personalized worksheets generated from session content
Auto-scored assessments (PHQ-9, GAD-7, and more) with longitudinal trend tracking

The Difference

Mediyn vs. cloud-first AI platforms.

Most therapy AI tools take a different approach to privacy, and many require you to stitch together multiple tools. Mediyn is different by design.

Beyond HIPAA

Compliance built into the workflow, not bolted on after.

Beyond HIPAA, therapy practices face the No Surprises Act, state telehealth licensing requirements, and recording consent laws. Mediyn builds compliance into the workflow — not as a checklist you manage separately.

Client Portal

Privacy protections extend to your clients too.

When clients access their portal to view sessions, complete assessments, respond to worksheets, or message their therapist — every interaction is protected by the same privacy-first architecture.

Passwordless login via magic link — no credentials to steal or phish
Biometric device authentication for trusted devices
Role-scoped PHI masking — clients only see data their clinician permits
Secure in-app messaging — therapist-initiated, text only, no file uploads
Auto-scored assessments and worksheets submitted through encrypted channels
Invoice access and payment without exposing clinical records
Explore the client portal
How Client Access Works

Secure by default.
Private at every step.

🔗

Magic link sent

Client taps a secure link from their email — no password to steal or phish.

🛡️

Device verified

Biometric authentication confirms identity on recognized, trusted devices.

👁️

Scoped access

Client sees only their records, masked to their clinician-set permission level.

📋

Every action logged

Immutable audit trail records every view, submit, and message.

Zero passwords. Minimal PHI exposure. Full audit trail.

FAQ

Common privacy questions.

What happens if my device is lost or stolen?

Raw audio files exist only on your device and are encrypted at rest. If a device is lost, the token-mapping data that links de-identified transcripts to client identifiers is inaccessible without your biometric or device passcode. You can also remotely revoke trusted devices from your account settings.

Can Mediyn staff access my clients' data?

PHI is role-scoped and masked server-side — not hidden with CSS. Re-authentication is required to unmask sensitive fields, and every unmasking event is logged in an immutable audit trail. Mediyn's access controls are designed so that support staff cannot access clinical content during normal operations.

What about telehealth sessions — does the same architecture apply?

Yes. When you conduct a video session through Mediyn's built-in telehealth, the audio is processed through the same on-device transcription and PHI redaction pipeline. Video streams are encrypted in transit and at rest, and are not recorded unless you explicitly enable recording.

Do you use client data to train your AI models?

No. Session recordings, transcripts, clinical notes, messages, and assessment responses are never used as training data — not for our models, and not for our third-party language model providers, who operate under zero-retention agreements.

What happens to my data if I cancel my subscription?

You have 90 days to retrieve your clinical data after account closure. After that, personal information is deleted. Clinical records are retained only as long as required by HIPAA and applicable state retention laws (typically 6-7 years).
