You choose a pathology. You give only the data related to it. You revoke at any time. Cryptographic anonymization, blockchain proof, no pharma or insurer access.
V2 — available after V1 stabilization. Module strictly outside medical device scope.
Dead End 1
Every university hospital keeps its data. Researchers spend months on agreements, sometimes years. The result: studies lack volume, results are delayed, treatments arrive later.
Dead End 2
When there is data, the patient is not consulted: their record leaves via framework agreements signed by their hospital. They don't know, don't choose, don't revoke.
We propose a third way: an explicit, granular, revocable patient contribution.
From the approved research programs displayed in your app: diabetes, Alzheimer's, cancers, rare diseases. Each program specifies the sponsoring laboratory, the objective, the duration, the data requested.
Not your full record: only the medical data related to the program (e.g. your glycemia and antidiabetic prescriptions, not your dermatology). Client-side filtering, before sending.
Pseudonymization, k-anonymity on identity traits (age bracket, region, sex), differential privacy on aggregates. Your passport and the researcher dataset are never linkable.
One tap in the app. Data already integrated into a study is removed from the next recalculation. Enforceable blockchain proof — including in case of litigation with the laboratory.
This is not a one-way extraction. Every discovery from the cohort is reinjected into contributors' apps — new recommendations, more precise alerts, improved follow-up.
You Consent
Pathology donation opt-in, granular, revocable.
The Researcher Observes
Anonymized aggregated data, without identity.
A Result Emerges
New protocol, new alert, new correlation.
You Benefit
The benefit returns to your app: recommendation, follow-up, prevention.
This loop is also the key to MDMC's data moat: the more we learn, the better we serve you, the more you benefit — without losing sovereignty.

No name, no birth date, no municipality. The researcher sees a citizen, not you.
Never. Written in our Terms of Sale. Labs pay to access cohorts, not to buy you.
Research data is not shared with commercial teams of laboratories. Verifiable contractual separation.
Insurers cannot buy access to our cohorts. Non-negotiable contractual clause.
An independent firm verifies every quarter that donation flows respect the framework. Public reports.
Pathology donation will open in V2. For now, create your V1 passport — zero commitment, free for life.
