01 — The healthcare context

Healthcare leaves no room for approximation.

Highly sensitive patient data, HDS and GDPR requirements, legacy or no-code applications at breaking point, and a constant tension between time-to-market and compliance. Building for healthcare means delivering on both.

Data that cannot afford mistakes

Patient records, imaging, results: the slightest leak compromises your liability and the trust of healthcare professionals. Security is not a luxury—it’s the foundation.

HDS and GDPR are non-negotiable

Certified health data hosting, access traceability, consent, right to erasure: the framework is strict, and it evolves. Better to build it in from the start.

Legacy systems that hinder care

Ageing business applications or no-code tools that can no longer handle the load or business rules: technical debt slows down teams and patients.

Move fast, without compromise

Operations demand delivery, compliance demands security. We refuse to choose: clear scoping, incremental delivery, security and compliance built in from the first line of code.

03 — Compliance & sovereignty

Compliance is not a checkbox.
It’s the foundation.

For a healthcare institution, the real question isn’t “does it work?” but “where does my data go, who accesses it, and can I leave?”. Here are our answers, clearly and without jargon.

Hosting on HDS-certified infrastructure

Your health data is hosted in France, on HDS-certified infrastructure (OVH, Scaleway). Depending on your needs: managed mode or self-hosting under your institution’s direct control.

No data outside the EU

No reliance on non-European cloud providers. Your patients’ data stays in France—this is the starting point, not an option.

RGPD by design

Data minimisation, traceable consent, right to erasure, processing register: RGPD is built in from the start, never added as an afterthought.

RLS on all tables

Row-Level Security at the database level: every access is filtered by role and institution. Data separation isn’t just application-level—it’s embedded in the engine.

Anonymisation & pseudonymisation

Data used for management or research is anonymised or pseudonymised based on use case. Identifiable data does not circulate without reason.

Guaranteed reversibility

The code is yours, the data is exportable, the hosting is transferable. You’re never locked in with Scroll.

06 — FAQ

Your questions, our answers.

The most common questions we address when scoping projects with healthcare institutions or healthtech startups.

HDS (Hébergeur de Données de Santé) is a mandatory French certification for hosting personal health data. It enforces strict security, confidentiality, and traceability guarantees. In practice: any application storing patient data must rely on HDS-certified infrastructure. We host your applications on HDS-certified infrastructure in France (OVH, Scaleway).

In France, on HDS-certified infrastructure. No data leaves the European Union. Depending on your needs, in managed mode or via self-hosting under your institution’s direct control.

Yes, by design: data minimisation, traceable consent, right to erasure, processing register, and Row-Level Security at the database level. GDPR compliance is built in from the scoping phase, not added later.

Yes. We audit the existing system (legacy, no-code, or AI-generated code), secure the data, then rebuild it on a maintainable, compliant foundation—step by step, with no service disruption. See our Migration no-code to code and Application modernisation expertise.

Yes, both. A university hospital, a clinic, a lab, or a healthtech startup have different constraints and rhythms—but the same compliance requirements. We tailor the scoping to your organisation.

Data encryption, Row-Level Security on all tables, access logging, anonymisation based on usage, and systematic code review. Security isn’t a final step—it’s embedded in the architecture.
