A passport designed as a digital twin
of your care journey.

We do not store your data: we model your health decisions. An open semantic layer, above the silos, governed by you.

Data first.
Decision first.

Healthcare is not a data warehouse: it is a chain of complex decisions between a patient, clinicians, labs and institutions. Our architecture models those decisions, not mere rows in a table.

The Classic Approach

One record, one database

Every medical software stacks its own tables, its own fields, its own permissions. The patient becomes a replicated row, never unified. Transfers are fragile, rights are blurry.

Our Approach

A living decision graph

Patient, care episode, prescription, diagnosis, consent — each entity is linked to the others by explicit relations. Each action (share, revoke, donate) is a versioned event. The care journey becomes readable again, for you and your clinicians.

Data, Logic, Action, Security.

Four interconnected dimensions, crossed by native security. None is bolt-on: all are woven into the heart of the system.

01

A semantic layer, not a silo

We unify your health data in FHIR R4 (international standard) and OMOP (research standard). Whether it comes from a lab, pharmacy, hospital or Mon Espace Santé: it speaks the same language.

02

The rules are yours

Granular consents, sharing policies, score calculations, orchestrations — every piece of logic acting on your data is explicit, auditable, modifiable. No algorithmic black box.

03

You act, the system executes

Five fundamental verbs: Share, Revoke, Donate, Export, Bequeath. Each action is a traced, reversible event backed by cryptographic proof.

04

Security runs through everything

End-to-end encryption by default, key on your device, consent blockchain, immutable audit trail. Security is not a layer on top: it is woven into every dimension.

Five actions. You, at the centre.

Most health platforms list features. We prefer to list what you can do.

Share

Granular access, by data, by professional, by duration. You choose exactly what Dr. Martin sees — and for how long.

Revoke

One tap. A doctor’s, a lab’s or an insurer’s access stops instantly. The revocation is written to the blockchain — verifiable in court.

Donate

You can contribute to research on a specific condition. With revocation possible at any time. Your donation stays anonymous, your control stays total.

Export

One click and you retrieve your entire passport in signed FHIR R4. Portable anywhere in Europe. Without asking our permission.

Bequeath

You designate the person who will inherit governance of your data in case of incapacity or death. Multi-jurisdiction, compliant with European family law.

Fragmented sources, a unified journey.

No vendor lock-in. Ever.

We build exclusively on international standards and open-source components. No confining proprietary technology, no dependence on an American or Asian vendor.

FHIR R4

HL7 international standard for clinical data. Native interoperability with any hospital system.

OMOP CDM

Common model for observational research. Used by 500+ institutions worldwide.

HAPI FHIR

Reference open-source FHIR server, battle-tested in European teaching hospitals.

Semantic graph

Link layer (patient ↔ episode ↔ prescription) for fluid navigation through the care journey.

Keycloak

Open-source identity and roles (patient, doctor, caregiver, researcher) with fine-grained permissions.

Permissioned ledger

Crypto-currency-free blockchain, for consent events only — not for data.
