Data handling

How we handle your data.

Hosting and data residency

The data plane, telemetry, transactional email and AI inference all run on Scaleway in Paris. No third-country transfer mechanism is involved in delivering the service.

Data residency
Customer data is stored and processed exclusively within the EU, on Scaleway fr-par (Paris).
EU hosting
Managed Scaleway services only: serverless containers, managed PostgreSQL, static hosting. Infrastructure is code, deployed through CI.
Sub-processor changes
One sub-processor covers the whole chain. Customers are notified before one is added or replaced, per the DPA.
Jurisdiction
Qastel AI SAS is a French company, operating as a processor under Art. 28 GDPR.

Access and encryption

Connectors request read-only scopes, listed in the security overview. Inline policy enforcement is a per-tenant flag that is off by default.

Access model
Connectors use read-only scopes (for example Application.Read.All, Directory.Read.All, AuditLog.Read.All on Entra ID). No write permission to customer tenants is requested for discovery.
Encryption
TLS on all public ingress and to the database. Provider-managed encryption at rest; connector credentials additionally encrypted with AES-256-GCM. Managed key rotation is on the roadmap.
Tenant isolation
Every request runs in a database transaction scoped to the tenant, with row-level security on core tables.
Sign-in
Email/password or Microsoft Entra work-account sign-in, rate-limited. Per-tenant enterprise SSO (SAML) and MFA are planned.

Operations

Security is owned by the CTO and operated by the founding engineering team. Every state-changing action is recorded with the acting identity and a trace ID.

Retention and deletion
Raw observations 90 days by default, adjustable per tenant; audit log 24 months. Tenant data is deleted on termination per the DPA; backups expire on a 7-day rolling window.
Audit log
Typed, append-only, enforced at the database level. Tenant administrators can view, filter and export it.
Vulnerability reporting
Write to security@qastel.ai. Application security is addressed through PR review, CI gates and pre-commit secret scanning.
Change notices
Sub-processor changes are notified per the DPA, and this page is updated in the same change.

FAQ

Frequently asked questions

If yours is not here, write to security@qastel.ai.

Where is customer data stored?

Exclusively in the EU: Scaleway fr-par (Paris) for the data plane, hosting, telemetry, transactional email and AI inference. No third-country transfer mechanism is involved.

Do connectors write anything to our systems?

No. Connectors observe and report back; they do not create, modify or delete data in the systems they connect to. The only writes are to Qastel's own database.

Can Qastel see prompts and outputs?

Only for tenants that opt into prompt insights, and then the prompt text is processed in memory for one classification call and never stored. What remains is topic counts and sensitivity categories, never the text.

How do we get the DPA?

Write to security@qastel.ai. The Article 28 template is sent on request.

Do you hold SOC 2 or ISO 27001 certification?

Not yet. Both are planned stages on the certification roadmap on this page, alongside an external penetration test. The compensating controls we run today are listed above.

Need the DPA or the sub-processor list?

We send the documents on request and notify you when they change.
